Abstract
One of the most important channels through which monetary policy affects the real
economy is changes in mortgage rates. This paper studies the effects of mortgage rate
changes resulting from monetary policy shifts on homeowners’ spending, debt repayment
and defaults. The Canadian institutional setting facilitates the design of identification
strategies for causal inference, since the vast majority of mortgages in the country
experience predetermined, periodic, and automatic contract renewals with the mortgage
rate reset based on the prevailing market rate. This allows us to exploit quasi-random
variation in the timing of the rate reset and present causal evidence for both rate declines
and increases, with the help of detailed, representative consumer credit panel data. We
find asymmetric effects of rate changes on spending, debt repayment and defaults. Our
results can be rationalized by the conventional cash-flow effect in conjunction with
changes in consumer expectations about future interest rates upon the reset. Given the
pervasiveness of Canadian-type mortgages in many other OECD countries, our findings
have broader implications for the transmission of monetary policy to the household sector.

1 Introduction
One of the most important channels through which monetary policy affects the real economy is
changes in mortgage rates. Lower mortgages rates, for example, reduce long-term borrowing costs
and debt service expenses, increase borrowers’ cash flows, and stimulate consumer spending in
economic downturns. A persistent challenge in evaluating the mortgage-rate channel has been
the identification of exogenous mortgage rate changes and their effects on consumer spending and
savings. Given the difficulty of using time series analysis to isolate the mortgage-rate channel from
all other channels through which monetary policy affects aggregate spending and savings, a growing
number of studies have turned to micro data and cross-sectional empirical strategies.
The work by Di Maggio et al. (2017), for example, focuses on U.S. adjustable-rate mortgage
(ARM) borrowers over a declining interest rate period. Their strategy, however, cannot be applied
to studying the causal effects of mortgage rate increases on consumer behavior in the U.S.,
because creditworthy consumers can always refinance their ARMs to avoid adjusting to higher
rates, creating a selection problem in the estimation. Empirical strategies used by other related
studies have relied on comparing ARM borrowers with fixed-rate mortgage (FRM) borrowers (e.g.,
Jappelli and Scognamiglio (2018); La Cava et al. (2016); Floden et al. (2021)), or comparing
mortgage borrowers with outright homeowners (e.g. Agarwal et al. (2022)), which is prone to the
selection-into-treatment concern. In addition, most studies have focused on a single episode around
the global financial crisis when major central banks slashed their policy rates.
1
The reversal of
the low policy rate environment since late 2021 in major economies has created interest in the
corresponding effects of a monetary tightening.
These challenges motivate us to explore a different institutional setting, the Canadian mortgage
market, using detailed, representative consumer credit panel data. Canada is an interesting case
to consider, because the institutional setting of the mortgage market permits a clean identification
design. The vast majority (about 80%) of mortgages in Canada are “short-term” FRMs that are
subject to predetermined, periodic and automatic contract renewals. Specifically, the interest rates
on these mortgages are fixed within a term (typically 2-5 years) and have to be reset at the end
of the term based on the prevailing market rate, while the balance is automatically rolled over.
1
The only other study that provides evidence for a monetary tightening is Agarwal et al. (2022). Unlike the
strategy used by Agarwal et al. (2022) that compares mortgage borrowers with outright homeowners, our comparison
is between similar mortgage borrowers that only differ in the timing of the contract renewal. Moreover, our sample
is nationally and geographically representative of mortgage borrowers, whereas the sample in Agarwal et al. (2022)
is representative of credit card holders.
1
Borrowers usually renew their contracts with their current lenders, in which case, their credit
scores, loan-to-value (LTV) ratios and debt-to-income (DTI) ratios are not reassessed, unlike when
originating a new mortgage. Moreover, due to large prepayment penalties, most borrowers renew
their contracts and reset their rates as scheduled.
These institutional features imply that the timing of the mortgage rate reset is determined by
past contract choices, and that the change in the mortgage rate upon the reset results from the
change in the prevailing market rate over the contract period, rather than being driven by the
borrower’s financial condition, creditworthiness, or spending decisions. Intuitively, we can compare
the responses of two borrowers that are similar in every aspect except that one borrower resets
the mortgage rate earlier than the other borrower. Our identification strategy, therefore, exploits
quasi-random variation in the timing of the rate reset in the Canadian mortgage-market setting.
Using this strategy, we provide evidence for two recent monetary policy episodes in Canada that
correspond to major policy shifts during our sample period (Figure 1): the expansionary episode of
2015m1-2017m1 and the contractionary episode of 2017m7-2019m6. We start by showing that these
policy changes were passed through to mortgage rates when borrowers renewed their contracts, with
the magnitude of the pass-through depending on the length of the contract term before the reset.
In the expansionary episode, the rate reduction ranged from 16 basis points (bps) to 113 bps, with
the largest reductions experienced by borrowers who had relatively long terms (e.g., four and five
years) prior to the reset. In the contractionary episode, renewing borrowers saw rate increases
of 32-85 bps, with the smallest increases experienced by borrowers who had relatively long terms
before the reset. Changes in rates translate to changes in interest payments. We estimate that
the required mortgage payments fell (rose) by $14-$92 ($34-$83) per month in the expansionary
(contractionary) episode, or by $2,907-$20,891 ($7,072-$19,165) over the remaining life of the loan,
if the borrower uses the same length of time to pay it off.
Given the changes in mortgage rates and payments upon the reset, we examine their effects on
consumer spending using two measures available in our data. One is newly originated auto loans
that capture spending on automobiles. The other is newly originated installment loans (excluding
student loans), which are often used by Canadian consumers to cover large, one-time expenses such
as home improvements and purchases of durable goods (e.g., furniture and consumer electronics).
Standard consumption theory predicts that consumers increase (decrease) their spending when
mortgage payments fall (rise), and that liquidity-constrained borrowers are more responsive to
2
these cash-flow shocks (e.g., Carroll (1997), Deaton (1991), and Kaplan and Violante (2014)).
Our results for the expansionary episode are in line with this theory: Borrowers receiving the
largest cash flows increased spending on automobiles by 16% and spending financed by installment
loans by 18%. Young borrowers and borrowers with higher credit scores are more responsive to
these shocks. In the contractionary episode, however, the types of spending measured in our data
did not change significantly, suggesting that consumers are willing to smooth their consumption
to a larger extent in response to negative cash flows. The asymmetric consumption responses to
income shocks have been documented in other contexts. For example, the work by Baugh et al.
(2021) shows that consumers increase their consumption when receiving tax refunds, but these
same consumers do not cut their spending when making tax payments, regardless of whether these
payments are expected or unexpected.
Another important aspect of household responses to mortgage rate changes is the balance-sheet
adjustment. If lower mortgage rates cause households to deleverage on their debt because of
positive cash flows, for example, the resulting strengthened balance sheets will support future
consumption. We therefore examine debt-repayment responses to rate resets, distinguishing
between mortgage prepayment and the paydown of revolving consumer credit, i.e., credit cards
and lines of credit (LOCs). Again, we find asymmetric patterns. Borrowers renewing their
contracts in the expansionary episode paid down their mortgage principal faster, by scheduling
higher monthly payments than the required amount for the new term, whereas borrowers in the
contractionary episode did not deviate from their required payments, implying no acceleration in
the amortization. For consumer revolving debt, while we do not find a change in the overall balance
in the expansionary episode, we document across-the-board repayments of this type of debt during
the contractionary episode. Taken together, these results imply that consumers deleveraged on
their debt in both episodes.
The asymmetric debt-repayment responses we document are new to the literature. Our findings
suggest that rate resets affect consumers not only through changes in cash flows, as stressed in
the previous literature, but also through other channels. Otherwise, negative cash flows in the
contractionary episode would drive consumers to accumulate more debt to smooth consumption.
We evaluate a number of potential explanations and provide evidence that changes in consumer
expectations about future interest rates help rationalize our findings.
The third aspect of household responses we examine is the change in the likelihood of being
3
delinquent on payments. In line with previous studies (e.g., Fuster and Willen (2017)), we find
lower delinquency rates on mortgages and consumer credit products as borrowers reset to lower
rates in the expansionary episode. In the contractionary episode, however, there is no evidence for
rising delinquencies, which may be explained by high expected costs of default and strict lending
standards in Canadian mortgage and consumer credit markets that ensure borrowers’ resilience to
negative cash flows.
Lastly, given our micro-level analysis, we expect rate resets to generate sizable effects on
aggregate spending when borrowers reset their rates to lower levels, and to contribute to aggregate
savings when borrowers experience rate increases. Since our sample is representative of Canadian
borrowers, we are able to provide estimates of the aggregate effects. Our estimates show that,
between 2015m1 and 2017m1, additional auto spending caused by mortgage rate resets amounted
to $2.02 billion, or 1.53% of aggregate new auto sales, while additional durable consumption financed
by installment loans amounted to $1.38 billion, or 0.42% of aggregate durable consumption. In the
contractionary episode between 2017m7 and 2019m6, deleveraging on revolving debt upon the rate
reset raised aggregate savings by $693 million, or 1.72% of the aggregate saving.
Relation to the literature. The importance of understanding the transmission of monetary
policy to households has given rise to a large number of studies on the effects of mortgage rate
changes on consumption, balance sheets and defaults (e.g., Di Maggio et al. (2017), Agarwal et al.
(2022), Jappelli and Scognamiglio (2018), La Cava et al. (2016), Floden et al. (2021), Tracy and
Wright (2016), Fuster and Willen (2017), Ganong and Noel (2020), Agarwal et al. (2017), Ehrlich
and Perry (2017), Karamon et al. (2017) and Abel and Fuster (2021)). Our paper falls into this
literature.
Among these studies, our paper is most closely related to Di Maggio et al. (2017) with three
major differences. First, as discussed earlier, the Canadian setting allows us to provide causal
estimates not only for the effects of declining mortgage rates, as in Di Maggio et al. (2017), but
also for the effects of rate increases during a monetary tightening period. Second, our results are
based on a nationally and geographically representative sample of Canadian mortgage borrowers,
whereas the sample underlying the main results of Di Maggio et al. (2017) is not representative
of the vast majority of mortgages or borrowers in the U.S., as shown in Appendix A. Specifically,
the jumbo prime interest-only ARMs in their study accounted for only 1.8% of the total U.S.
mortgage origination in 2005-2007, and almost half of this type of mortgages were originated in
4
California alone. Whether the consumption and payment responses of these ARM borrowers can
be generalized to a typical American consumer who is likely to hold a 30-year FRM is unclear.
Third, as in other related studies, Di Maggio et al. (2017) interpret rate resets as cash-flow shocks,
whereas our paper suggests that rate resets also affect consumer responses through expectations of
future interest rates.
More broadly, our work is related to the literature on consumption and saving responses to
income shocks (e.g., Baugh et al. (2021), Agarwal and Qian (2014), Agarwal et al. (2007), Johnson
et al. (2006), Parker et al. (2013), and Kaplan and Violante (2014)), and the literature on the
transmission of monetary policy shocks to households through housing and mortgage markets and
various other channels (e.g., Kaplan et al. (2018), Cloyne et al. (2020), Beraja et al. (2019), DeFusco
and Mondragon (2020), Wong (2021), Greenwald (2017), Chen et al. (2020), Hurst and Stafford
(2004), Bhutta and Keys (2016) and Zhou (2022)). We discuss in more detail the relation between
our work and these studies in subsequent sections.
The remainder of the paper is organized as follows. Section 2 discusses key institutional features
of the Canadian mortgage market, an overview of the Canadian consumer credit market, and
the credit panel data used in our analysis. Section 3 describes the empirical strategy. Section
4 examines the effects of rate resets on mortgage loan-level outcomes. Section 5 examines the
effects on consumer-level outcomes, discusses and evaluates the channels through which resets affect
consumers, and provides evidence from expectations survey data that supports the expectations
channel. Section 6 presents estimates for the aggregate effects of rate resets on spending and debt
repayment. Section 7 provides further evidence and robustness checks. Section 8 concludes.
2 Institutional Setting and Data
2.1 Canadian Mortgage Market
The Canadian mortgage market has several important institutional features that facilitate our
identification design. First, unlike the U.S. mortgage market where long-term FRMs are dominant,
the vast majority of Canadian mortgages have short terms (2-5 years) and long amortization periods
(25-30 years).
2
The amortization period is the length of time it takes to pay off a mortgage, whereas
the term is the length of time the contract, especially the mortgage rate, is in effect. Having a
2
Our credit panel data show that 95% of FRMs in Canada have a term of 2, 3, 4 or 5 years. Since FRMs account for
80% of the market, the four products, 2-, 3-, 4- and 5-year FRMs, together account for 76% of the entire Canadian
mortgage market, with 5-year FRMs most popular (accounting for 60% of FRMs). The Bank of Canada-OSFI
Mortgage Origination Dataset confirms the high presence of these four products (73% of total originations since
2014).
5
mortgage term that is shorter than the amortization period requires the borrower to renew the
contract by the end of the term. Upon the renewal, the remaining balance is rolled over and
the mortgage rate is reset based on the prevailing market rate.
3
Typically, by the end of the
amortization, a mortgage contract would have been renewed several times.
Consumers are allowed to change the length of the term in the renewal process. In our data,
consumers holding the most common contracts, i.e., 2- and 5-year FRMs, tend to keep their previous
contract length at renewal (see Appendix Table D1). For example, 65% of 2-year FRM borrowers
and 68% of 5-year FRM borrowers who renewed their contracts between 2015 and 2017 chose the
same term length as in the previous term. Other borrowers, such as those holding a 3- or 4-year
contract, either maintained their previous term length or switched to a more common term, 2 or 5
years, that is closer to their previous term length. We defer the discussion of how the switching of
contract terms can potentially affect our empirical results to Section 7.
Second, most borrowers renew their mortgage contracts with their current lender. We estimate
that among borrowers who eventually renewed their mortgages between 2015 and 2017, 98% did so
with their current lender. This share fell slightly to 97% in 2017-2019.
4
When a mortgage is renewed
with the current lender, the lender in general does not reassess the borrower’s risk measures, such
as the credit score and LTV and DTI ratios. Thus, both rate increases and decreases are passed
on to the borrower automatically. This feature differs from mortgage refinancing in the U.S. that
almost always requires reassessing the underwriting criteria.
Third, the existence of prepayment penalties ensures that borrowers renew their mortgage
contracts as scheduled. Although the penalty varies from lender to lender, it is usually the higher
of (i) three months’ interest on the remaining balance, and (ii) the interest differential based on the
contract rate and the current market rate for a term of the same length as the remaining time left
on the current term. When the mortgage rate declines, the interest-differential penalty captures all
financial gains from prepaying the mortgage in full and originating a new mortgage at a lower rate.
In practice, borrowers may renew their contract slightly earlier than scheduled without paying a
penalty, provided that their current lender allows them to do so. As shown in Figure 2, more than
3
Mortgage rates at the borrower level may vary slightly with the borrower’s bargaining power (Allen et al. (2014,
2019)). In our analysis, we control for borrower fixed effects and a set of borrower characteristics, which help remove
the sources of variation in bargaining power.
4
These shares are computed using information in Appendix Table D2. In the expansionary episode, for example,
the probability of renewing the contract with the current lender conditional on the event that the consumer
eventually renewed her contract is (0.72+0.28*0.1*0.38)/(0.72+0.28*0.1)=0.98. Likewise, this probability is 0.97
in the contractionary episode.
6
98% of renewals in our data occurred in the six months leading up to the scheduled dates, with
on-time renewals accounting for 50%.
5
The existence of prepayment penalties also reduces the incentive of Canadian consumers to
extract their home equity through cash-out refinancing, a process that involves paying off the
current balance and originating a new loan secured by the same property with a higher balance.
Cash-out refinancing is most likely to happen when a consumer approaches her scheduled renewal
date and when prepayment penalties do not apply. Using our data, we identify cash-out refinancing
activity for loans terminated before the scheduled renewal (see Table D2), and then estimate the
annual cash-out refinancing propensity to gauge the quantitative importance of this activity. We
estimate this propensity to be 3% in Canada between 2015 and 2017, which is much smaller than the
7%-11% propensity in the U.S. during the early-2000s refinancing boom, according to Bhutta and
Keys (2016).
6
Compared to cash-out refinancing, taking out home equity lines of credit (HELOCs)
is not subject to prepayment penalties and is more flexible in the amount that consumers can
borrow, hence more prevalent in Canada (Ho et al. (2019)). We study the effect of rate resets on
HELOC balances in Section 5.
2.2 Canadian Consumer Credit Market
A central part of our analysis is the effects of mortgage rate resets on the balances and payments
of consumer credit that includes revolving debt, such as credit cards and LOCs, and non-revolving
debt, such as auto, installment and student loans.
7
As in many countries, consumer credit
constitutes an important part of household debt in Canada, provides indicators for changes in
consumer spending and savings, and is closely watched by policymakers assessing financial risks.
The Canadian consumer credit market shares some common features with the US market.
First, it accounts for a significant share of outstanding household debt in both countries, about
34% in Canada (according to Statistics Canada) and 24% in the U.S. (according to the Federal
Reserve Board) since 2015. The difference is partially driven by the statistical agencies’ treatment
of HELOC debt, which is classified as consumer credit in Canada but as mortgage debt in the U.S.
5
While not fully prepayable, Canadian mortgage contracts allow for an annual prepayment of up to 20% of
the initial balance on top of the scheduled amortization without penalty. This partial prepayment, however, is not
associated with a change in the mortgage rate, and hence does not affect our identification.
6
We estimate the Canadian cash-out refinancing propensity as follows. According to Table D2, among borrowers
scheduled to renew their mortgages, the share of cash-out refinancing borrowers is 13% (=28%*46%). In the
population, the share of borrowers scheduled to renew their contracts among all FRM borrowers is 25% in a year.
Taking these facts together, we estimate the annual cash-out refinancing propensity to be 3% (=25%*13%) over the
2015-2017 period. This propensity is slightly lower in the 2017-2019 period (2.6%), when interest rates moved up.
7
For the purpose of our study, we exclude student loans, which represent 5% of the overall consumer credit balance
between 2015 and 2019 and are even less important among homeowners.
7
Excluding HELOC debt, consumer credit accounts for 22% of Canadian household debt, much closer
to the US share. Second, the per capita balances and credit utilization rates on comparable debt
instruments, such as auto loans and credit cards, are similar in the two countries, after accounting
for the exchange rate (by comparing the TransUnion Canada data and the New York Fed Consumer
Credit Panel Reports). These features suggest broad applicability of our estimates to economies
with similar consumer credit markets.
On the other hand, there are some differences between the two markets. First, apart from
the classification of HELOCs, the importance of HELOC debt in overall household debt differs
substantially. Whereas HELOC balances accounted for less than 4% of US household debt after
2015, it captured almost 12% of Canadian household debt over the same period. This is likely
explained by the less prevalent use of cash-out refinancing as a tool for home equity extraction
in Canada as discussed earlier. The second difference is the lower delinquency rates in Canada
compared to the U.S. The percentage of balances delinquent for more than 90 days in the U.S., across
different consumer credit products, was about four to eleven times as high as the corresponding
percentage in Canada over the period we study. This is likely explained by the tight lending
standards in Canadian mortgage and consumer credit markets, as well as the high expected costs
of default in Canada. As we show in Section 5.5, even in the contractionary episode, delinquencies
did not rise for borrowers who resett their mortgage rates to higher levels.
2.3 Data
We use granular account-level (or trade-line-level) data provided by TransUnion Canada, one of the
two credit reporting agencies in Canada, which collects information on 35 million individuals and
covers nearly every consumer in the country that has had a credit report. The data are available
from 2009 onwards at the monthly frequency.
8
For each consumer, we merge mortgage loan-level
information with consumer-level information on non-mortgage debt that is compiled by ourselves
using account-level data on auto loans, installment loans, credit cards and LOCs. This bottom-up
approach allows us to precisely identify the timing and the amount of a purchase that is financed
by an auto loan or an installment loan.
The mortgage loan-level data have information on the origination date, initial amount, insurance
8
The data collected by TransUnion Canada are reported in accordance with the Metro 2 format of the Canadian
credit reporting guidelines, which specify the variables for reporting. To protect the privacy of Canadians, no
personal information was provided by TransUnion. The TransUnion dataset was “anonymized,” meaning that it does
not include information that identifies individual Canadians, such as names, social insurance numbers or addresses.
In addition, the dataset has a panel structure, which uses fictitious account and consumer numbers assigned by
TransUnion.
8
status, whether the loan is taken out jointly, and whether the borrower is the primary holder of
the loan, as well as other origination information. The data also include monthly updates on the
current balance, scheduled payment, term duration, delinquency status and whether the loan is
terminated. Information on non-mortgage debt follows a similar data structure. Moreover, the
data provide information about a borrower’s age, credit score, and forward sortation area (FSA,
corresponding to the first three digits of a postal code).
For the purpose of our study, knowing the exact timing of a rate reset is crucial. Not all
mortgages in the dataset can be associated with their renewal dates, however, because some lenders
do not report the term duration information, making it impossible to infer the renewal dates of
their mortgages. For this reason, we use mortgages issued by one of the largest commercial banks
and their corresponding consumers as our sample. This bank is the only major bank that reports
the term duration information.
Our sample is representative of the mortgages and borrowers in Canada. First, mortgages
originated by the bank have very similar characteristics to those originated by other federally
regulated lenders (see Table 1). Second, the bank’s share in Canadian mortgage originations and in
the aggregate stock of Canadian mortgages are both close to 20%. Third, the bank operates in all
regions of the country and has a market share of about 20% in each Canadian province, suggesting
the geographic representativeness of our sample.
2.4 Construction of Key Variables
Mortgage rates. Our analysis requires information on the mortgage rate type (i.e., fixed or
variable) and the mortgage rate, which is not provided by the TransUnion data. To identify the
mortgage rate type, we classify a loan as fixed-rate in a term if the scheduled monthly payment
does not change during that term.
9
We then design a procedure to recover the rates associated
with these FRMs. In Appendix B, we describe in detail how these rates are constructed and how
we use two alternative datasets that contain information on actual mortgage rates to validate our
procedure. We show that the distribution of the imputed rate based on this procedure closely
matches that in the two alternative datasets.
Required monthly payments. Given the new mortgage rate upon the reset, we construct a
payment schedule that is not observed in our data but measures the automatic adjustment of
the monthly payment implied by the rate reset. In constructing this variable, we assume the same
9
Although some lenders in Canada offer fixed-payment schedules for variable-rate mortgages, the lender in our
sample typically does not.
9
remaining amortization period and the same outstanding balance as in the month prior to the reset.
Comparing the change in this required payment to the change in the scheduled payment set by the
borrower allows us to examine the choice between mortgage prepayment and cash withdrawal upon
the reset.
Remaining amortization. If a borrower sets a higher monthly payment than the required
amount, the remaining amortization period shortens. For each renewed mortgage, we first use
the pre-renewal rate, balance and monthly payment to infer the remaining amortization had the
mortgage not been renewed. We then use the post-renewal rate and monthly payment and the
pre-renewal balance to infer the amortization after the reset.
Spending measures. We construct two measures for durable spending. First, we use newly
originated auto loans as proxies for spending on automobiles.
10
Since we work directly with
loan-level data, we can precisely identify the timing and the amount of a vehicle purchase that
is financed by an auto loan. Second, we use newly originated installment loans (excluding student
loans) to measure broader types of durable spending. In Canada, these loans are designed to cover
large one-time expenses and are typically used for home improvements and purchases of furniture
or other durable goods.
Classifying HELOCs. The original account-level data do not distinguish between HELOCs,
which are secured by borrowers’ homes, and unsecured LOCs. While both types of LOCs are
revolving debt products, the former have lower rates and provide a more important source for
homeowners to smooth their consumption.
11
Hence, we are particularly interested in understanding
changes in HELOC balances upon the rate reset. We follow the industry practice in classifying
HELOCs as LOCs that have initial credit limits of at least $50,000. Our empirical results are robust
to changing this threshold.
Delinquency measures. Given loan-level information on the delinquency status, we create
consumer-level measures of delinquency on each type of debt as follows. First, we create an indicator
at the loan level that takes the value of one if the loan in the current month approaches a certain
level of delinquency (60 or 90 days). We then count the number of newly delinquent accounts for
each type of debt. Finally, we convert the number of newly delinquent accounts into a dummy
10
According to Watts (2016), as of 2016, 83% of new motor vehicles in Canada were obtained with financing, and
the trend of financed vehicle sales has closely tracked that of total sales. In addition, historical data show that the
average LTV ratio of motor vehicles in Canada is close to 100%.
11
Bailliu et al. (2012) estimate that 40%-50% of the funds extracted from home equity is used for consumption
and home improvement in Canada.
10
variable that indicates new delinquency on at least one account of a given debt category.
Constructing LTV ratios. Since the credit panel data do not provide borrower-level information
on house prices, we instead construct the FSA-level LTV ratio and include its lag as a control
variable in our regressions. Specifically, we use the FSA-level median house price in 2014Q1 (from
the Bank of Canada-OSFI mortgage originations dataset) multiplied by the growth rate of the
Teranet quarterly FSA-level house price index to obtain the FSA’s current-quarter house price. We
then divide the median mortgage balance of the FSA’s consumers by the imputed current-quarter
house price of the FSA to obtain the LTV ratio.
2.5 Summary Statistics
Table 2 shows the summary statistics of key variables at the mortgage loan level and at the consumer
level.
12
We perform the analysis on loans renewed in 2015m1-2017m1 for the expansionary episode,
and on loans renewed in 2017m7-2019m6 for the contractionary episode. For tractability, we restrict
our analysis to FRMs that have (pre-renewal) terms of 2, 3, 4 or 5 years, which jointly account for
95% of the FRM market. Summary statistics are presented for each term separately. Our analysis
is restricted to primary mortgage holders. Borrowers that have more than one mortgages at the
same time are excluded. In total, we have 88,328 loans renewed during the expansionary episode
and 85,376 loans renewed during the contractionary episode.
3 Empirical Strategy
Our empirical strategy is designed to exploit variation in the predetermined timing of mortgage
rate resets in the two episodes. In essence, we compare the responses of two borrowers who are
similar in every aspect except that one borrower resets her mortgage rate earlier than the other
borrower. Our analysis is carried out separately for each mortgage term in each episode, so we can
focus on borrowers with similar contracts and avoid the potential concern of selection into specific

13
Economy theory suggests that consumers may respond differently to the same mortgage rate
shocks due to heterogeneity in their wealth and access to credit markets. We consider three
empirical measures to quantify these heterogeneous responses. First, we use the average credit
score over the preceding 12 months as a proxy for the borrower’s access to new credit. Second,
we use the average utilization rate of revolving credit over the preceding 12 months as a proxy for
constraints on existing, available credit. Third, we use ages under 45 or above 65 as a proxy for low
liquidity levels compared to middle-aged consumers. This choice is consistent with the prediction of
standard life-cycle theory and the patterns in household survey data (e.g., the Survey of Consumer
Finances and Panel Study of Income Dynamics). We interact each of these empirical measures with
the post-renewal indicator, P ostRenew
j,t
, for the estimation of heterogeneous effects.
Consumers may change their spending and savings before the reset in anticipation of a rate
change upon the reset. To evaluate the importance of this anticipation effect, we estimate the
dynamic version of equation (1) that includes a set of quarterly dummies to replace the post-renewal
indicator. Specifically, we estimate the α

three quarters before and five quarters after the renewal relative to quarter zero.
One potential concern with our baseline strategy is its inability to account for the mortgage-age
effect. For example, consumers may be less likely to buy a car at the time when they buy a house,
perhaps because they have used up their savings to make the mortgage down payment, or because
13
Our results are robust to including the province-by-quarter fixed effects or the cohort-by-quarter fixed effects.
The first set of fixed effects controls for region-specific time trends. For example, the effect of oil price shocks may
vary substantially across regions, as the oil sector is geographically concentrated in Canada (see Kilian and Zhou
(2020)). The second set of fixed effects controls for unobserved heterogeneity across cohorts.
12
they are too leveraged to be qualified for a new auto loan. As consumers accumulate savings after
the home purchase, they are more likely to buy a car. This means that consumers’ auto spending
increases with the age of their mortgage. The existence of this mortgage-age effect threatens our
identification, because we might attribute the increase in auto spending to the effect of the rate
reset. Ideally, we would include a set of dummy variables indicating the age of the mortgage. These
variables would be collinear with the post-renewal indicator, so we cannot control for them.
We therefore implement two alternative difference-in-difference (DID) strategies for robustness.
First, we consider a design that introduces FRMs with long terms (7 or 10 years) as the control
group. These mortgages were previously renewed at the same time as mortgages in our sample.
Essentially, this strategy compares two mortgages that were both previously renewed in, say,
2010m1. One was renewed again in 2015m1, while the other had to wait for another two years.
In the second design, we introduce as the control group mortgages having the same terms as the
treatment group but not renewed in the episode. For example, in the expansionary episode, we
use 5-year FRMs previously renewed in 2012m1-2013m1 (hence not renewed in the expansionary
episode) as the control group for 5-year FRMs renewed in this episode. This approach mitigates
the selection concern arising from comparing different types of mortgage contracts.
Both designs can be implemented by estimating the following specification:

is the indicator for loan j to be renewed in an episode. Other variables are similarly
defined as in equation (1). The parameter of interest is β
1
, which captures the DID effect. As we
discuss in Section 7, the estimates using the baseline strategy are similar to these DID estimates.
4 Mortgage Loan-Level Adjustments
We start by estimating the changes in the mortgage rate and required monthly payment upon the
reset, and then turn to the change in the monthly payment scheduled by the borrower. The latter
reflects the borrower’s choice of whether to pay down the mortgage principal faster by deviating
from the required payment. Heterogeneity in this choice across borrowers shows support for the
prediction of standard consumption theory.
4.1 Changes in Mortgage Rate and Required Payment
Column (1) of Table 3 shows the change in the mortgage rate for each term. In the expansionary
episode, borrowers renewing their mortgages experienced substantial downward adjustment in the
13
rate. The magnitude, however, depends on the term prior to the reset. Mortgages with relatively
longer terms had larger declines in rates. For example, the average decline was 113 bps for 5-year
FRMs, but 16 bps for 2-year FRMs. This difference is due to the fact that the prevailing market
rate had already been declining before the episode started, leading to larger cumulative changes for
mortgages with longer terms.
Lower mortgage rates imply savings on required interest payments. In column (2), we estimate
the change in the required monthly payment, which quantifies the maximum payment reduction
per month the borrower can realize in the new term. Consistent with the rate-change pattern,
5-year FRM borrowers had the largest reduction in the new required payment, $92 per month on
average, whereas the reduction for 2-year FRM borrowers was only $15 per month. Given the
remaining amortization for each type of mortgage, we estimate the total interest savings upon the
reset, assuming that the amortization and mortgage rate do not change. This ranged from a modest
amount of $2,907 to a substantial amount of $20,891, depending on the pre-renewal term (see Table
4). As we show in Section 4.2, borrowers also shortened their amortization upon the reset, implying
further interest savings.
In the contractionary episode, borrowers renewing their mortgages experienced rate increases.
The magnitude decreases with the term prior to the reset, due to the reversal of the declining rate
trend. Borrowers with 2-year FRMs, for example, experienced the largest rate increase of 85 bps,
whereas borrowers having 5-year FRMs encountered a 32-bp rate increase on average. We estimate
that the monthly required payment increased by $34-$83, depending on the pre-renewal term.
Assuming the amortization and current rate unchanged, the total increase in interest payments
upon the reset in this episode ranged from $7,072 for 5-year FRM borrowers to $19,165 for 2-year
FRM borrowers.
These estimates represent the average changes experienced by borrowers who renewed their
mortgages in an episode. At the individual level, however, the changes may differ depending
on the timing of the renewal. In the contractionary episode, for example, the prevailing market
rate increased gradually following the policy rate movements (Figure 1), implying that borrowers
renewing their mortgages early in the episode experienced smaller increases in rates and payments
than borrowers renewing their mortgages later, even though they held the same type of contract.
Our estimates put more weight on mortgages renewed early in an episode (due to more observations
of these loans in the post-renewal period), which could cause us to underestimate the true average
14
increases in rates and payments.
To address this concern, we provide estimates using the sample that restricts the post-renewal
observations to be within four quarters for each loan. The results are shown in Appendix Table D4.
For the contractionary episode, the average increases in rates and payments are indeed larger than
the baseline estimates, with differences of 20 bps in rates and $20 in required payments. For the
expansionary episode, the average decreases in rates and payments are smaller than the baseline
estimates. These loan-level differences, however, do not affect much our borrower-level outcomes,
i.e., durable consumption and debt repayment, as shown in Section 5.
4.2 Changes in Scheduled Payment and Amortization
When renewing the mortgage contract, a borrower, given the new rate, may choose a different
monthly payment from the required amount. In principle, the payment chosen by the borrower must
not fall below the required level. Scheduling a higher monthly payment than the required amount
allows the borrower to pay down the mortgage principal faster and to shorten the amortization.
Comparing the change in the required payment to the change in the scheduled payment, therefore,
allows us to infer the borrower’s decisions on mortgage prepayment and liquidity withdrawal.
In the expansionary episode, we find that, indeed, borrowers did not set their new payments
to the low levels required by lenders (Table 3, column 3). For example, 5-year FRM borrowers on
average only lowered their monthly payments by $46, despite the maximum possible reduction of
$92 per month. A similar pattern is found for other types of renewing mortgages. This implies that
only part of the interest savings were realized, and that the rest were used to pay down the principal
faster. How much faster? We estimate the change in the remaining amortization in column (4) of
Table 3. Depending on the term, the amortization period was shortened by 4-14 months. Taking
this into account, we estimate that total interest savings upon the reset ranged from $4,830 to
$23,925 for renewing borrowers (Table 4).
In the contractionary episode, we find that borrowers set their new monthly payments to the
levels required by the lenders, leaving the amortization essentially unchanged. The asymmetric
responses of scheduled payments are not surprising, given that lenders in general do not allow
borrowers to schedule a payment lower than required, nor do they permit extensions of the
amortization.
Another way of paying down the mortgage principal is to make a large, one-time payment at
the point of the renewal. The data, however, do not seem to support the prevalence of such large
15
prepayments upon the reset. We find that, only 3.7% of borrowers reduced their balances by more
than 5% upon the reset in the expansionary episode, and that this fraction dropped to 3.2% in the
contractionary episode. In addition, the fraction of borrowers who reduced their balances by more
than 20% is at most 1% in each episode.
4.3 Heterogeneity in Mortgage Payment Choices
We showed that, in the expansionary episode, borrowers used part of their interest savings from the
reset to pay down their mortgage principals faster. There are reasons to believe that this pattern
varies across borrowers. Standard consumption theory predicts that liquidity-constrained borrowers
would allocate more of their interest savings to spending and less to debt prepayment. Here we
focus on borrowers who experienced large payment declines (i.e., 4- and 5-year FRM borrowers) and
examine whether constrained borrowers responded differently from others. Liquidity constraints
are measured using the credit score, credit utilization and age, as described in Section 3.
Table 5 supports the theoretical prediction. We compute the ratio of the change in
the scheduled payment to the change in the required payment as a measure of liquidity
realization. Consider two groups of borrowers who renewed their 5-year FRMs, one with high
credit scores and the other with low credit scores. Our estimates show that the liquidity
realization ratio for high-credit-score borrowers is 37% (=30.02/82.24), whereas it is 65%
(=[30.02+32.90]/[82.24+14.09]) for low-credit-score borrowers. Similarly, this ratio is 37% for
borrowers with low credit utilization and 68% for borrowers with high credit utilization. Likewise,
this ratio is 57% for young borrowers, 47% for middle-aged borrowers, and 58% for old borrowers.
Turning to borrowers renewing 4-year FRMs, we find the similar pattern that liquidity-constrained
borrowers converted more of their interest savings to liquidity than other borrowers.
In contrast, we do not find heterogeneity in this ratio in the contractionary episode (not shown
to conserve space). Borrowers set their scheduled payments to the required levels and left the
amortization unchanged, regardless of the liquidity measure. The lack of heterogeneity in the
payment choice in this episode may again be explained by lenders’ policy that the scheduled payment
in general cannot fall below the required level.
5 Mortgage Rate Resets and Consumer-Level Responses
This section examines the effects of rate resets on consumer spending, debt repayment, and defaults.
We find interesting asymmetric responses that cannot be fully explained by the cash-flow channel
16
of the rate reset. This motivates the discussion of alternative channels. We evaluate a number of
possible explanations and provide evidence for the consumer expectations channel using household
survey data.
5.1 Consumer Spending
We find that consumers experiencing the largest rate and payment reductions, i.e., 5-year FRM
borrowers, increased their durable spending significantly in the expansionary episode. On average,
monthly auto spending and spending financed by installment loans rose by $19 and $44, respectively,
equivalent to a 16% and an 18% increase relative to the sample mean (Table 6, columns 1 and 3).
The results also show that rate resets led some consumers who otherwise would not have spent on
these goods to do so. For example, the likelihood of purchasing an automobile increased by 7 bps
in a month (column 2), equivalent to a 19% increase from the mean; the likelihood of taking a new
installment loan increases by 14 bps in a month (column 4), equivalent to a 15% increase from the
mean.
14
We also address the question of whether these borrowers may have already raised their spending
before the reset, and whether their spending was completely reversed after the initial increase. The
dynamic responses in Figure 3 show that sharp increases in auto and installment-loan-financed
spending occurred in the quarter of the reset. The two types of spending remained high for the
next few quarters. In five quarters, total spending reached $400 for automobiles and $500 for that
financed by installment loans, suggesting somewhat lasting effects of rate resets on spending.
Before turning to the contractionary episode, we examine spending heterogeneity, focusing on
5-year FRM borrowers. Standard consumption theory predicts that liquidity-constrained borrowers
would be more responsive to positive cash flows. On the other hand, since interest savings are not
realized immediately but over the course of the new term, difficulties in obtaining new credit may
create a hurdle for some consumers who would have borrowed to finance their current spending.
Our findings can be summarized into three points (see Table 7). First, while all borrowers increased
their spending upon the reset, low-credit-score borrowers were less responsive, suggesting that they
may have limited access to new credit or face high borrowing costs. Second, young borrowers are
more responsive than other age groups, consistent with the theory. Third, there is no significant
heterogeneity across credit utilization, which may be explained by the inability of high-credit-usage
borrowers to obtain more credit.
14
We do not find significant spending responses of borrowers renewing other terms of mortgages. This is not
surprising, given that the size of the rate reduction is small for these borrowers.
17
In the contractionary episode, interestingly, we do not find decreases in spending. In fact, with
one exception, spending did not change significantly. The only exception is the change in the
likelihood of auto purchases for 2-year FRM borrowers, which is positive, not negative. Nor did
spending decrease at longer horizons (5 quarters). Among borrowers with the same type of contract,
the only noticeable heterogeneity is that low-credit-score borrowers reduced their spending relative
to others, confirming the role of credit market access in explaining spending divergence.
The lack of spending responses in the contractionary episode raises the question of whether
our measures of spending are inadequate for capturing overall consumption responses to negative
cash flows. This is possible, given that our data only measure durable spending financed by auto
or installment loans. However, asymmetric consumption responses have also been documented in
other studies using more comprehensive consumption measures. Baugh et al. (2021), for example,
using detailed account-level data on spending made by credit cards, debit cards, and checking and
savings accounts, find that consumers respond asymmetrically to positive and negative cash flow
shocks. Specifically, while consumers increase their consumption upon receiving tax refunds, these
same consumers do not cut their spending when making tax payments in other years, regardless of
whether these payments are expected or unexpected.
15
5.2 Revolving Debt Balances
Previous studies have documented debt repayment as an important use of positive cash flows (e.g.,
Di Maggio et al. (2017), Bhutta and Keys (2016), and Baugh et al. (2021)). Our results in Section
4.2 showed that consumers pay down their mortgage principal faster when resetting to lower rates,
in line with these studies. We now examine the responses of the balances on revolving credit, i.e.,
credit cards and LOCs.
In the expansionary episode, we find that consumers on average paid down their credit card
debt by about $130-$250 upon the reset (or 3%-6% of the mean balance), as shown in column (6)
of Table 6. Deleveraging on credit card debt, however, was completely reversed by rising LOC
balances (column 7), and in particular by higher HELOC balances (column 8). The rise in HELOC
balances indicates that homeowners extract their home equity in response to lower rates (see Bhutta
and Keys (2016)). As a result, the total revolving balance did not change significantly (column
5). Figure 4 shows the dynamic responses of credit card and LOC balances for 2- and 5-year FRM
15
One may also be concerned that the insignificant estimates are driven by the lack of power of our tests. Recall that
we find strongly statistically significant spending responses in the expansionary episode for 5-year FRM borrowers.
For the contractionary episode, we apply exactly the same estimation strategy on the sample of a similar size, so the
insignificant spending responses in this episode cannot be attributed to a lack of power.
18
borrowers. Credit card balances fell sharply in the quarter of the reset and stayed roughly flat for
the next few quarters, whereas LOC balances rose gradually.
The change in the revolving balance displayed substantial heterogeneity across borrowers. Panel
I of Table 8 shows the results for 5-year FRM borrowers (with similar patterns observed for other
renewers). Overall, high-credit-score, low-credit-usage and old borrowers deleveraged more. The
fact that low-credit-score and high-credit-usage borrowers deleveraged less, sometimes even raising
their leverage, suggests that these borrowers may rely more on existing credit to smooth their
consumption in response to positive cash flows. This can also be seen from the relatively smaller
reduction in their credit utilization rate compared to other borrowers.
16
Turning to the contractionary episode, our findings for the responses of revolving debt balances
to rising mortgage rates and payments are novel to the literature. We find that consumers paid
down their credit card debt by about $210-$270 upon the reset, equivalent to 5%-6% of the average
balance (Table 6, column 6). Unlike in the expansionary episode, credit card deleveraging was not
offset by rising LOC balances (column 7). Nor do we observe equity extraction through HELOCs
(column 8). Even over longer horizons, LOC balances did not rise (Figure 4, panel b). As a result,
the revolving balance fell by $260-$900 upon the reset, except for 4-year FRM borrowers who
displayed no significant change. Among borrowers with the same type of contract, high-credit-score,
low-credit-usage and old borrowers deleveraged more, similar to the patterns observed for the
expansionary episode (Table 8).
5.3 Other Channels of Rate Resets
While our results at the consumer level for the expansionary episode support the conventional
interpretation of rate resets being cash-flow shocks, the findings for the contractionary episode
reveal that other channels are at work in driving consumer responses. This is because, if the
cash-flow effect dominates when rates increase, consumers are expected to cut their spending or
to raise their debt to smooth the effect of negative cash flows, according to standard consumption
theory. In contrast, we find spending unchanged and revolving balances reduced. We consider
several potential explanations of this fact and evaluate their plausibility.
17
16
Regarding heterogeneity in the age dimension, first, we find that old borrowers deleveraged more than other
borrowers on both credit cards and LOCs, consistent with the prediction of life-cycle theory. Second, young borrowers
deleveraged less on credit card debt than other borrowers, but more on LOCs than middle-aged borrowers. The second
finding may be explained by the fact that young borrowers have high LOC utilization (90%), compared to credit-card
utilization (55%).
17
The fact that rate increases led to higher mortgage payments, that consumer spending was unchanged, and
that revolving debt was paid down means that consumers must have reduced their savings to finance these increased
payments. We do not observe household assets in our data, but evidence in Baugh et al. (2021) supports this point
19
First, one may argue that changes in revolving debt balances simply reflect changes in
expenditures not captured by our data (e.g. nondurables and services), and that the reduction
in these balances means lower consumption. This would support the view that negative cash flows
are the main channel through which rate resets affected consumers in the contractionary episode.
This explanation, however, is challenged by two facts. First, it cannot explain why consumers who
experienced the largest negative cash-flow shocks (i.e., 2-year FRM borrowers) did not deleverage
more than borrowers who experienced the smallest cash-flow losses (e.g., 5-year FRM borrowers).
Second, it implies that liquidity-constrained borrowers would cut their spending more and hence
reduce their debt balances more than other borrowers, which is the opposite to what we find in the
data.
Second, lenders may force borrowers to deleverage on revolving debt when borrowers reset their
mortgage rates to higher levels, due to the concern that borrowers’ repayment ability may be
undermined by rising mortgage payments. We test this hypothesis by estimating changes in banks’
credit supply to consumers in response to rate resets in the contractionary episode. Columns (1)
and (2) of Table 9 show the change in the likelihood of experiencing a more than $1,000 increase in
the credit limit. This likelihood did not fall, but increased, for credit card debt and for LOC debt.
Columns (3) and (4) show the dollar changes in these credit limits, confirming the patterns in the
previous two columns. Lastly, we estimate the change in the required-payment-to-balance ratio,
which reflects the interest rate on the debt (especially for interest-only products). We do not observe
any significant change in this ratio (columns 5 and 6). To summarize, we do not find supporting
evidence for deleveraging driven by the lender-side tightening of credit in the contractionary episode.
Third, we consider a monthly debt-service-ratio hypothesis that predicts that consumers act to
maintain a constant debt service ratio, i.e., the ratio of monthly debt service payments over monthly
income. Testing this hypothesis is equivalent to testing the hypothesis of constant debt service
payments, provided that consumers’ monthly income does not change.
18
When mortgage payments
rise, for example, the latter hypothesis suggests that consumers pay down their non-mortgage debt
to keep their total debt service expenses unchanged. We test this hypothesis by estimating the
change in monthly total debt service payments (on mortgages, auto and installment loans, and
revolving debt) to the rate reset. The null hypothesis is no change. The results are shown in
by showing that consumers make account transfers, rather than reduce their consumption, in response to net income
losses resulting from tax payments.
18
The two hypotheses are equivalent in our setting because our empirical strategy exploits variation in the timing
of the rate reset which is exogenous to changes in consumers’ income (e.g., labor, government transfers, etc.).
20
Appendix Table D3. We find that total monthly payments moved closely with monthly mortgage
payments, with the difference mainly driven by payments on revolving debt. In the contractionary
episode, in particular, the declines in revolving debt expenses were too small to offset the rising
mortgage payments. Hence, we do not find strong support for this hypothesis.
Lastly, we consider an explanation which postulates that, when consumers reset their mortgage
rates to higher levels in the contractionary episode, they expect interest rates to increase in the
future as well.
19
Since revolving debt often has variable rates, the expectations about rising
future rates drive consumers to pay down this type of debt. Our credit panel data do not
contain information on expectations, so we employ an alternative dataset for the expectations
of representative Canadian consumers to evaluate this hypothesis in Section 5.4.
This expectations channel is closely related to the standard intertemporal-substitution (IS)
channel that predicts that consumers pay down their debt (or equivalently, increase their net
savings) when the current interest rate rises. The expectations channel generalizes the standard IS
channel in two dimensions. First, it links the deleveraging response not only to the current interest
rate but also to the expected future interest rates. Second, it does not necessarily imply symmetric
interest-rate expectations or symmetric deleveraging responses, consistent with our findings.
20
5.4 Consumer Expectations
We use the Canadian Survey of Consumer Expectations (CSCE) to evaluate the expectations
channel in explaining consumer deleveraging in the contractionary episode. The CSCE data are
collected every quarter since 2014Q4 from a nationally representative household sample. The
survey asks questions related to households’ financial conditions and their expectations about
macroeconomic variables. A detailed description of the data, the survey questions underlying
our analysis, and key summary statistics can be found in Appendix C.
For comparability with our consumer credit panel data, we restrict the CSCE survey sample
to homeowners with mortgages. We establish two sets of results using the CSCE data that jointly
19
The fact that borrowers holding 2-year FRMs were more likely to switch to longer terms in the contractionary
episode than in the expansionary episode suggests that these borrowers may expect rates to rise for an extended
period (Appendix Table D1).
20
These differences are driven by the standard assumption in rational expectations dynamic equilibrium models
that interest rates are constant over time. This assumption gives the standard Euler equation: u

and are symmetric in these models. In contrast, a more general model that relaxes the constant-rate assumption

that both the current rate and the expectations about future rates matter for the current saving decisions and that

21
support the expectations channel. First, consumers who perceive that interest rates have risen over
the past 12 months tend to expect the interest rates to be even higher for an extended period (at
least 5 years). Second, in response to their expectations about rising future rates, consumers are
more likely to pay down debt, cut spending and save more. These patterns persist in the overall
sample and, in particular, in the contrationary episode.
To establish the first fact, we estimate the following fixed-effect linear probability model (LPM)
that relates consumers’ perception of recent interest rate changes to their expectations of the rate
in the next 12 months,

= γ

where ExpectH

is an indicator equal to 1 if consumer i in quarter t expects the average interest
rate to be higher in the next 12 months. CurrentH
i,t
is an indicator equal to 1 if the consumer
perceives that interest rates have risen over the past 12 months. x
i,t
is a vector of consumer
characteristics (i.e., age, gender, marital status and education). γ
i
and δ
t
are consumer and time
fixed effects. The standard errors are clustered at the consumer level. Column (1) of Table 10
shows that consumers who perceive that interest rates have risen are more likely to expect rates to
be higher in the next 12 months.
We next consider expectations at longer horizons. The survey asks consumers about their
expected levels of interest rates in one, two and five years, which allows us to construct indicators
for the rising path of expected future rates. Specifically, we construct an indicator for expecting
rates to rise in the next two years, which equals one if the consumer (i) expects rates to be higher
in the next 12 months, and (ii) reports the level of the expected rate in two years greater than
the level of the expected rate in one year. Likewise, an indicator for expecting rates to rise in the
next five years is constructed, which equals one if the consumer meets conditions (i) and (ii), and
reports the level of the expected rate in five years above the level of the expected rate in two years.
The results in columns (2) and (3) of Table 10 show that consumers who perceive current rates to
have risen are also more likely to expect future rates to increase for an extended period.
To establish the second fact, we take advantage of the survey question that asks consumers
about the actions they are taking or plan to take in response to their interest rate expectations,
including paying down debt, cutting spending/saving more, postponing major purchases, and
bringing forward major purchases. Respondents can choose multiple actions, so we estimate a
series of LPMs similar to equation (4) with one action being a dependent variable at a time.
22
Columns (4) to (7) in Table 10 show that consumers who perceive rates to have risen are more
likely to pay down their debt, as well as to cut their spending/save more, providing direct support
to the expectations channel in explaining deleveraging in the contractionary episode.
For the expectations channel to explain our earlier results based on the consumer credit panel
data, we have to argue that rate resets must have helped consumers to better understand the
current interest rate, which then triggers changes in their expectations about future rates. This is
not unreasonable, given that mortgage renewals are one of the most important financial decisions
for consumers that require their attention. Moreover, interactions with the lender in the process
are likely to draw consumers’ attention to the current market rate. At other times, consumers are
less likely to pay attention to movements in interest rates, as inattention in general is a well known
problem in the household finance literature (e.g., Keys et al. (2016), Andersen et al. (2020) and
Agarwal et al. (2016)).
We use the CSCE data to provide some evidence for the effect of rate resets on household
expectations. Since the survey does not ask questions about mortgage renewal, we use the indicator
for having a variable-rate mortgage, V RM

The results support our hypothesis. For the contractionary episode, the point estimates, ˆη

=
0.1 and ˆη
2
= 0.07 (both strongly statistically significant at the 1% level), imply that borrowers that
frequently or recently reset their mortgage rates are more likely to perceive interest rates to have
risen. For the expansionary episode, the point estimates, ˆη
1
= 0.03 and ˆη
2
= 0.01, suggest that
these borrowers are also more likely to perceive interest rates to have fallen over this episode.
One more piece of evidence supporting the expectations channel is that the average consumer
does not seem to have symmetric expectations about future interest rates. Appendix Table C1
shows that, in the contractionary episode, the majority of consumers perceived rates to have risen
(76%), and that 81% of these consumers expected rates to be higher in the next year. In contrast,
in the expansionary episode, while the majority of consumers perceived rates to have fallen or
unchanged (82%), only 49% of them expected rates to be lower or unchanged in the next year.
23
These patterns suggest that, while expectations played a key role in explaining deleveraging in
the contractionary episode, they may not have a symmetric effect on debt accumulation in the
expansionary episode, which is consistent with our findings in the credit panel data.
5.5 Mortgage and Consumer Credit Delinquency
Previous studies using U.S. data have found that lower mortgage rates help reduce mortgage
defaults, shedding light on the policy design that aims to support households in the aftermath
of the global financial crisis.
21
As major economies start to move away from the low policy rate
environment, additional research on the impact of rising interest rates on credit defaults is called
for.
There has not been a causal-inference based study of this issue, however. One challenge in using
U.S. data is that, before the financial crisis, ARM resets in the U.S. almost always led borrowers
to increase their monthly payments, and many borrowers responded by refinancing (Fuster and
Willen (2017)). This introduces a selection problem, because borrowers in poor credit conditions
are unlikely to refinance. Thus, comparing ARM borrowers who end up resetting to higher rates
(i.e., who are unable to refinance) with ARM borrowers who are still in the initial rate-fixation
periods could overestimate the effect of rate increases on default. In fact, this selection problem
poses an identification challenge not only for estimating the effect on default, but also for the
spending and savings responses using ARM resets.
Focusing on the Canadian mortgage borrowers allows us to circumvent this problem, as discussed
in Section 2.1. The results are shown in Table 11. In the expansionary episode, we find that
lower mortgage rates through the reset reduced mortgage delinquencies, especially for 5-year FRM
borrowers, in line with studies using U.S. data. We also find that delinquencies on other types of
debt fell for these borrowers. However, we do not find that delinquencies change significantly for
other renewing borrowers.
In the contractionary episode, we do not find that delinquencies increase for borrowers resetting
their rates to higher levels. This is consistent with our earlier finding that consumers deleveraged on
revolving debt over this period. It may seem surprising that higher mortgage payments did not cause
rising delinquencies. One explanation is that strict lending standards in Canada ensure borrowers’
resilience to negative cash-flow shocks ex post. For mortgages, for example, the regulatory and
supervisory framework has successfully kept mortgage delinquencies at very low levels even during
21
See, e.g., Tracy and Wright (2016), Fuster and Willen (2017), Ehrlich and Perry (2017), Agarwal et al. (2017),
Ganong and Noel (2020), Karamon et al. (2017), and Abel and Fuster (2021).
24
the global financial crisis, with the highest arrears rate being only 0.45% in January 2011 according
to the Canadian Bankers Association. After the global financial crisis, the government tightened
mortgage qualification rules, further pushing down the delinquency rate. Another explanation is
the high expected cost of default. For example, almost all mortgages in Canada have recourse
provisions (Crawford et al. (2013)).
The Canadian consumer credit market also faces tight lending standards. The subprime loans
have been a very small segment of the market, effectively reducing delinquencies on auto loans and
credit cards, for example. Moreover, the prevalent use of HELOCs as consumer credit means that
this credit is secured by properties, lowering the overall delinquency rate.
In both episodes, we find that the average credit score increased upon the reset across all
contract types. This is consistent with our findings that (i) in the expansionary episode, borrowers
who reset their rates paid down mortgage debt, and (ii) in the contractionary episode, borrowers
who reset their rates paid down revolving debt.
6 Aggregate Effects of Mortgage Rate Resets
Given our micro-level analysis, we expect mortgage rate resets to generate sizeable effects on
aggregate spending when borrowers reset their rates to lower levels, and to contribute to aggregate
savings when borrowers experience rate increases. Since our credit panel data are representative of
Canadian borrowers, we are able to estimate the aggregate effects on spending and savings.
Specifically, the effect of rate resets on aggregate spending or savings at time t can be computed
by integrating the corresponding effects across borrowers with different types of FRMs who renew
their mortgages at t,

where D denotes the pre-renewal mortgage term. R

is the average change in the mortgage rate
upon the reset for borrowers with term-D FRMs.
D

is the interest rate semi-elasticity, i.e., the
change in spending or savings for a 100-bp change in the mortgage rate. φ
t
(D) is the total number
of borrowers who renew their term-D FRMs at t. We next describe how this formula is computed
for each category: (i) auto spending, (ii) durable consumption, (iii) mortgage pay-down, and (iv)
revolving debt pay-down. A summary of these aggregate effects can be found in Table 12.
Aggregate effect on auto spending. We estimate that the total increase in auto spending
caused by rate resets in the expansionary episode (2015m1-2017m1) was $2.02 billion, equivalent
25
to 1.53% of the Canadian aggregate new auto sales over this period. This spending estimate is
obtained as follows. R
D
t
is set to the corresponding rate change in Table 3 (column 1, panel I).
The interest rate semi-elasticity of auto spending,
D
t
, is set to $1,380 for all borrowers.
22
φ
t
(D) is
estimated using Census data on the total number of mortgages in Canada, multiplied by the share
of term-D FRMs, further multiplied by the fraction of renewers among term-D FRM borrowers.
We estimate this effect for 2-, 3-, 4- and 5-year FRM borrowers, add these effects together, and
divide this sum by 95% to reflect the share of these four products in the Canadian FRM market.
We also estimate a lower bound for the aggregate auto-spending effect, which is solely based on
the effect of 5-year FRM renewals, setting the effects of all other renewals to zero. This gives an
increase in aggregate auto spending of $1.55 billion, or 1.17% of Canadian aggregate new auto sales
over this period. For the contractionary episode, since we do not find a significant causal change
in auto spending at the micro level, the estimated aggregate effect is zero.
Aggregate effect on durable consumption. A similar calculation is used for the effect on
aggregate durable consumption. The only difference is the calibration of
D
t
, which is set to $942.
23
We estimate that the total increase in durable consumption caused by rate resets in the expansionary
episode (2015m1-2017m1) was $1.38 billion, equivalent to 0.42% of Canadian aggregate durable
expenditures over this period. The aggregate effect of 5-year FRM renewals, which may be viewed
as the lower bound for this effect, was $1.06 billion (0.32% of aggregate durable expenditures). For
the contractionary episode, the aggregate effect was zero, given that no causal evidence was found
for a change in durable expenditures financed by installment loans at the micro level.
Aggregate effect on mortgage pay-down. As shown in Section 4, in the expansionary episode,
borrowers used part of their monthly interest savings to pay down their mortgage faster. Here we
assess the total mortgage principal paid down over the lengths of borrowers’ new contracts upon the
resets. For each term D, we multiply the difference between the required and scheduled payments
(Table 3) by the length of the new term (assumed to be D). The aggregation is similar to that for
estimating aggregate spending. We estimate that $3.56 billion of mortgage debt was paid down in
borrowers’ new terms due to the resets in the expansionary episode. Most of this effect came from
the contribution of 5-year FRM borrowers, who paid down $2.71 billion of mortgage debt in their

This semi-elasticity is computed using the estimated monthly increase in auto spending of 5-year FRM borrowers
($18.56) multiplied by 84 to reflect the length of auto loans (usually 7 years), further divided by the rate change of
5-year FRM borrowers upon the reset (113 bps) for normalization.
23
This semi-elasticity is computed using the estimated monthly increase in spending financed by installment loans
of 5-year FRM borrowers ($44.36) multiplied by 24 to reflect non-auto durable consumption in 2015m1-2017m1,
further divided by the rate change of 5-year FRM borrowers upon the reset (113 bps) for normalization.
26
new 5-year term. The aggregate mortgage principal paid down due to resets in the contractionary
episode was much smaller, about $0.4 billion at most.
Aggregate effect on revolving debt pay-down. We apply formula (6) to estimate this effect.
R
D
t
and φ
t
(D) are calibrated similarly as before.
D
t
is term-specific, set to the corresponding
change in total revolving debt (Table 6, column 5) divided by the change in the mortgage rate
(Table 3, column 1) for normalization. The aggregation shows that, in the contractionary episode,
$693 million of revolving debt was paid down, accounting for 1.72% of aggregate saving over this
period. The contribution from 5-year FRM renewing borrowers was relatively small, about $300
million, as deleveraging was across the board (except for 4-year FRM renewers). Since we do not
find significant change in revolving debt upon the reset in the expansionary episode, the aggregate
effect was zero for that episode.
Time variation in aggregate effects and policy implications. Formula (6) suggests that the
aggregate effect of rate resets may vary over time due to the change in the rate upon the reset, R
D
t
,
even though the interest rate semi-elasticity,
D
t
, and the distribution of borrower types, φ
t
(D), are
stable over time. The Canadian interest rates have been declining since the global financial crisis,
so there were other periods when borrowers experienced sizeable rate changes upon the reset. It
is useful to understand the effects of rate rates in the historical context. To this end, we extend
our analysis from the two recent episodes to the entire period for which the credit panel data are
available and apply formula (6) at the monthly frequency.
Panel (a) of Figure 12 shows the change in the mortgage rate for 5-year FRM borrowers upon
the reset, which displays substantial time variation. The largest decline occurred around December
2012, about 250 bps. These borrowers previously reset their rates in late 2007, right before the
Bank of Canada slashed the policy rate in response to the global financial crisis. This sharp decline
in the mortgage rate led to substantial aggregate spending effects, as shown in panels (b) and (c).
For example, total spending on automobiles increased by about $180 million in December 2012,
accounting for almost 6% of the Canadian aggregate new auto sales in that month. Similar patterns
are observed for durable consumption.
These patterns are consistent with those in the related studies: Mortgage borrowers resetting
their rates after the global financial crisis through adjustable-rate mortgages in the U.S. (Di Maggio
et al. (2017)) or through variable-rate mortgages in Australia (La Cava et al. (2016)) experienced
substantial consumption growth. Our analysis also suggests that, as countries have been staying
27
in the low-policy-rate environment for a long time since the financial crisis, and as the room for
cutting the conventional policy rate becomes constrained, the reduction in the mortgage rate for
borrowers who experience resets may be limited, weakening the potency of the rate-reset channel
of monetary policy (Berger et al. (2021)).
7 Further Evidence and Robustness Analysis
This section provides additional analysis and robustness checks that support our findings in Sections
4 and 5. They help address a number of potential concerns arising from the switching of terms,
issues with the baseline identification strategy, the anticipation effects, and institutional features
of the Canadian mortgage market.
Switching of terms. As discussed in Section 2.1, some borrowers switch to a different term length
during the renewal, while others stay with the same length as in the previous contract. For the
baseline estimates, we do not restrict the term length to be the same before and after the reset.
Thus, these estimates capture the average effects across all post-renewal terms. One concern is that
if borrowers with shorter-term FRMs systematically switch to longer-term FRMs at the renewal or
vice versa, our baseline estimates of rate changes, for example, would be confounded by the rate
spreads between different types of mortgages. As shown in Table 2, the mortgage rate is increasing
in the mortgage term.
To address this concern, we redo the analysis in Sections 4 and 5 with the sample that restricts
the term length to be the same before and after the reset. Table D5 shows the results. As expected,
the rate reduction for 2-year FRM borrowers is larger than the baseline in the expansionary episode,
and the rate increase is smaller in the contractionary episode. Changes in rates for other FRM
borrowers are similar to the baseline estimates. The responses of payment choices, consumption
and debt repayment are similar to the baseline estimates. For example, borrowers use part of
their interest savings to pay down mortgage debt in the expansionary episode. In addition, 5-year
FRM borrowers increase their spending when rates decline. Spending does not change when rates
increase. We also see that borrowers deleverage on revolving debt in the contractionary episode
and find no evidence of rising delinquencies.
Difference-in-difference (DID) estimates. As discussed in Section 3, one concern with our
baseline strategy is the inability to account for the mortgage-age effect that could confound the
effect of rate resets. To address this concern, we employ a DID design with the control group
being 7- and 10-year FRMs previously reset at the same time as the FRMs in our baseline sample.
28
Table D6 shows the results using this approach. At the loan level, it confirms that mortgages reset
in the two episodes experienced substantial changes in rates and payments with the magnitudes
varying with the pre-renewal term. The asymmetric mortgage prepayment choices are preserved
as in Section 4.2. The consumer-level responses of spending, debt repayment and delinquencies
are quantitatively similar to the baseline estimates. The only noticeable difference is that, in the
expansionary episode, deleveraging appears on both credit card debt and LOC debt.
The main reason why we do not use this alternative specification as the baseline strategy is that
the size of the control group is small, as not many Canadian borrowers take longer-term FRMs. In
the data, 7- and 10-year FRMs account for only 2% of the mortgage stock. In addition, one might
be concerned about the endogenous selection into these mortgage products. For these reasons, we
estimate a second DID specification with the control group being FRMs that had the same terms as
the treatment group but were not renewed in the two episodes. As shown in Table D7, these DID
estimates are similar to the baseline estimates and to the first set of DID estimates. One caveat of
the second DID approach is that we are unable to obtain a control group for 2-year FRMs, because
all existing 2-year FRMs would be renewed in a 2-year episode.
Anticipation effects. An interesting question is whether the consumer-level responses in Section
5 should be interpreted as the responses to anticipated mortgage rate changes. Economic theory
suggests that unconstrained, rational-expectations consumers respond to the news of the shock, not
the anticipated realizations of the shock. It is possible that consumers may have already anticipated
the change in their mortgage rates before the actual reset. If this is true and if consumers are not
liquidity constrained, in the expansionary episode, we would see a jump in their spending before
the actual reset. This is not what we see in the data, however. Spending increased only when
consumers actually reset their rates. One may argue that this is due to the presence of the liquidity
constraint that prevents consumers from reacting before the cash flow arrives. This is unlikely,
because liquidity-constrained consumers only account for a small fraction of the population.
Another way of assessing the importance of the anticipation effect is to compare consumers’
responses in a period when mortgage rate changes are unexpected to the responses in a period
when rate changes are of similar sizes but more likely to be anticipated. The monetary policy rate
29
cut in January 2015 was widely considered as a surprise to the market.
24
We therefore compare the
responses of borrowers who renewed their mortgages in 2015Q1 to the responses of borrowers who
renewed their mortgages in 2015Q2. Our premise is that, if the anticipation effect is important,
borrowers in the former group should have stronger responses than in the latter group. We do
not find significantly different responses across the two groups of borrowers. This pattern holds
even when we compare borrowers who who renewed their mortgages in February 2015 to those who
renewed their mortgages in March 2015. These results suggest that anticipation effects, if they
exist, are weak and are unlikely to alter our estimates.
25
Ahead-of-schedule renewals. As shown in Figure 2, about 50% of borrowers renew their
mortgages earlier than scheduled. This raises the question of whether on-time renewals and
ahead-of-schedule renewals result in different responses to the same shock. We perform additional
analysis to address this question. First, we restrict the sample to borrowers who renew their
contracts on time and estimate their responses to rate resets. The results are similar to the
baseline estimates. Second, we interact the post-renewal indicator with a set of dummies that
indicate the months ahead of the scheduled renewal. Again, we do not find different responses of
borrowers making ahead-of-schedule renewals. We do find, however, that the mortgage rates from
early renewals are slightly lower than on-time renewals, but the differences are small compared to
the overall rate changes.
Mortgages renewed in both episodes. When assessing the asymmetric effects of rate resets,
we would ideally focus on the same borrowers who experienced resets in both episodes. Due to
the timing of the two episodes, we only observe a subset of 2- and 3-year FRM borrowers who
experienced resets in both episodes. None of the 4- or 5-year FRM borrowers in our sample had
two resets with one in each episode. Nevertheless, we perform a robustness check using the sample
of the 2- and 3-year FRM borrowers who experience both resets. In unreported results, we show
that the loan-level and consumer-level responses are very similar to those in Table D5.
24
Although the monetary policy statement makes it explicit that the decision was in response to the sharp drop
in oil prices, the decision, when it came, was unexpected by many observers. In fact, the market had been predicting
a rate increase later that year. See, for example, Shecter (2015), “Bank of Canada’s surprise rate cut seen hurting
Canadian banks’ profits,” Financial Post, January 21, 2015; “Bank of Canada shocks markets with cut in key interest
rate,” CBC Business News, January 21, 2015.
25
This finding may be explained by consumers’ inattention to movements in interest rates or the uncertainty about
the realizations of the mortgage rate change.

8 Conclusion
One of the most important channels through which monetary policy affects the real economy is
changes in mortgage rates. This channel is particularly relevant for policymakers in countries
dominated by variable-rate mortgages, adjustable-rate mortgages and Canadian-type fixed-rate
mortgages, as changes in the policy rate in these countries are passed through automatically to
most homeowners, affecting their consumption and savings.
We study the effects of mortgage rate changes driven by monetary policy shifts on consumer
spending, debt repayment, and defaults in Canada, taking advantage of the institutional features of
the Canadian mortgage market. This setting facilitates the design of a clean identification strategy
for causal inference. In addition, the high-quality consumer credit panel data allow us to examine
changes in a consumer’s entire credit portfolio at a monthly frequency. Most importantly, we are
able to provide a detailed analysis of how consumers respond to rate increases and decreases.
Our findings for the expansionary episode, while new, are broadly in line with those using data
from other countries. Consumers increase durable spending, pay down mortgage debt, and reduce
the likelihood of being delinquent. In the cross-section, liquidity-constrained borrowers obtain
more cash from their interest savings, but their ability to use debt to finance durable spending is
limited by their access to new credit. Since cash flows resulting from lower mortgage payments are
realized over the course of several years, the difficulty in accessing credit markets may dampen the
immediate effect of monetary stimulus on consumer spending.
Our findings for the contractionary episode call into question the conventional wisdom.
Specifically, we do not find that durable spending decreases when mortgage rates increase. This
implies that consumers either dissave to maintain their consumption or cut other types of spending.
We also document a robust pattern that consumers lower, rather than increase, their revolving
debt level, which cannot be reconciled with the cash-flow interpretation of rate resets. We provide
evidence that this pattern is explained by changes in expectations about future rates. Finally, we
do not see rising delinquencies or tightening of credit supply for borrowers who reset their rates to
higher levels.
Our analysis of the contractionary episode suggests that mortgage rate resets do not appear to
discourage durable spending, render consumers more leveraged or increase the likelihood of defaults,
as commonly asserted in the financial press. Of course, our paper examines only one aspect of
mortgage rate changes, namely, the resets experienced by existing homeowners. There are other
31
channels through which mortgage rate changes may affect households, for example, home sales and
house prices, wealth effects resulting from changing asset prices, and home equity extraction. We
leave these issues for future research.
The Canadian-type short-term FRMs we focus on are quite common in other OECD countries.
Previous studies of the relationship between mortgage payments and consumer behavior have largely
relied on data from the U.S.. It is unclear whether the U.S. evidence can be generalized to other
countries. The U.S. is unique in having an unusually high share of long-term FRMs, the extensive
use of securitization in housing finance, and the absence of prepayment penalties (see Lea (2010)).
Although our estimates may depend on the choice of the episodes and the Canadian socio-economic
conditions, our qualitative insights should apply more broadly to other countries.

Source: Bank of Canada. The overnight rate is the interest rate at which major financial institutions borrow and
lend one-day (or “overnight”) funds among themselves. The Bank of Canada sets a target level for that rate, often
referred to as the Bank’s policy rate. The first vertical line indicates the beginning of our micro data. The other two
lines indicate the beginning of the two episodes in our study, 2015m1 and 2017m7.

Source: CoreLogic; Di Maggio et al. (2017).
Di Maggio et al. (2017) provided a comprehensive analysis of the effects of ARM resets on consumer
spending and mortgage repayment in the U.S. during the Great Recession. The sample underlying
their main results consists of mortgages in a specific segment of the U.S. mortgage market: jumbo
prime ARMs. Their study finds large, persistent increases in durable spending at the micro level,
which argues for the potency of the mortgage rate channel of monetary policy in stimulating the
U.S. economy. To assess the aggregate effects of ARM resets and to provide policy prescriptions,
however, it is important to understand the representativeness of the mortgages in their study.
26
To shed light on this issue, we accessed the CoreLogic Private Label Securities-MBS dataset
through the Federal Reserve System’s RADAR Data Warehouse. The dataset covers over 90 percent
of the loans of prime jumbo securities in the market. We first assess the share of the loans underlying
the main results of Di Maggio et al. (2017) in the U.S. mortgage market, i.e., jumbo prime 10-year
interest-only ARMs originated in 2005-2007 with an initial fixed interest-rate period of 5 years. We
estimate that these loans accounted for about 1.8% of the overall U.S. mortgage originations at the

Another issue with assessing the aggregate effects of ARM resets during periods of declining rates in the U.S. is
that long-term FRM borrowers would also take advantage of the low rates to refinance their mortgages, confounding

time.
27
We next examine loan characteristics of these ARMs. The summary statistics are shown in Table
A1. Overall, the distributions of the credit score, LTV ratio and initial interest rate are similar in
the two datasets. The main difference is the balances of 5-year ARMs, which are $570K on average
in our data, compared to $360K in the BlackBox Logic data. This discrepancy is not driven by the
outliers in our data. The 25th percentile of the balance distribution, for example, is $350K in our
data. Despite this difference, the average loan balances in both datasets are much larger than that
on representative agency FRMs, which was between $214K and $275K in 2005-2007, according to
Freddie Mac.
A somewhat surprising finding is the geographic concentration of this type of loans. California
alone accounted for 46% of its originations (compared to the state’s population share of 12%).
Another state that disproportionately originated these loans was Virginia. In addition, we find
that these loans had high prepayment rates, about 50%. About 70% of the prepayments were
voluntary payoffs and 20% were foreclosures.
To conclude, the small share of these loans in the U.S. mortgage market and their distinct
features and geographic concentration suggest that the behavior of the corresponding borrowers may
not be representative of a typical American consumer who is likely to hold a 30-year FRM contract.
This also highlights that more research and broader evidence might be needed to understand the
rate reset channel of monetary policy.
27
This market share is computed as follows. The share of jumbo loans originated in 2005-2007 is close to 30% of
the market (see, FDIC Quarterly Volume 13(4), 2019). In our prime-jumbo sample, 10-year interest-only ARMs over
the same period accounted for 20%, of which loans with an initial fixed interest-rate period of 5 years are about 30%.
The market share, therefore, is 1.8% (=30%×20%×30%).
51
B. Construction of Mortgage Rates
We take a series of steps to impute the rates associated with the FRMs in our sample. First,
assuming no prepayment in addition to scheduled payments, the outstanding balances and scheduled
payments can be used to pin down the mortgage rate (adjusted to annual rate). Second, from the
rates obtained in the first step, we remove the ones that are either too low (most likely due to
prepayment beyond the amortization schedule) or too high (most likely due to delays in payments).
Third, we take the median of the remaining rates within each term of a mortgage as the contracted
rate. Finally, we winsorize our contracted rates using the 1% cutoff at the top and bottom the
distribution. A minor caveat of this procedure is that we are unable to recover the rates for a small
fraction of loans that feature either systematic prepayment or frequent delays in payments.
To externally validate our procedure, we compare the imputed rates in our data with the actual
rates reported in two datasets. One is the average 5-year FRM rate quoted by national mortgage
brokers, and the other is the loan-level rate recorded in the Bank of Canada (BOC)-OSFI mortgage
originations dataset. The broker data span a long time period, but do not have a cross-sectional
dimension. The BOC-OSFI dataset allows us to further break down the data by mortgage insurance
status and purpose, but is available only since 2014. Mortgages in both sources are new originations,
so we compare their rate distributions with those of the new originations in our sample.
Figure B1 shows that the average and median of our imputed rates track the brokers’ rate
quite closely over time. Classifying mortgages by their insurance status, Figure B2 shows that the
imputed rates are similar to the rates in the BOC-OSFI dataset, and that the rate differentials
for insured and uninsured mortgages are small. Although our sample does not distinguish between
loan purposes, the BOC-OSFI dataset suggests that the rates for home purchases and for cash-out
refinances are similar, especially for uninsured mortgages. We also compare the standard deviations
of our imputed rates with those in the BOC-OSFI dataset by insurance status. The standard
deviations are similar, with a gap of about 20-30 bps over the sample period.

C: Canadian Survey of Consumer Expectations
The Canadian Survey of Consumer Expectations (CSCE), launched by the Bank of Canada in
2014Q4, provides comprehensive information about consumer expectations of inflation, interest
rates, labor markets, credit markets and housing markets. The survey also collects information on
households’ demographics, employment situation and financial conditions. Data are collected from
a nationally representative sample of 1,000-2,000 household heads every quarter. The survey has a
rotating panel structure with respondents participating in the panel for up to a year. The design
of the survey largely follows that of the New York Fed’s Survey of Consumer Expectations. See
Gosselin and Khan (2015) for a detailed description of the CSCE.
For our analysis in Section 5.4, we restrict the sample to homeowners with mortgages to make
it comparable with our consumer credit panel data. Summary statistics of the regression variables
are presented in Table C1. The following survey questions are used to construct the key variables
in the regressions.
1. “How would you say interest rates on things such as mortgages, bank loans and savings have
changed over the last 12 months? Fallen a lot, fallen a little, about the same, risen a little,
risen a lot?” We use the answer to this question to construct an indicator variable for
perceiving that interest rates have risen. The indicator equals one if the consumer answers
risen a lot or risen a little.
2. “What do you think is the percent chance that 12 months from now the average interest rate
on things such as mortgages, bank loans and savings will be higher than it is now?” We use
the answer to this question to construct an indicator variable for expecting the rates to be
higher in the next 12 months. The indicator equals one if the consumer gives a numerical
answer greater than 50%.
3. “At what level do you think that interest rates on things such as mortgages, bank loans and
savings will be in...?” Please enter a number.
(a) One year from now, interest rates will most likely be __%
(b) Two years from now, interest rates will most likely be __%
(c) Five years from now, interest rates will most likely be __%
We construct an indicator for a consumer expecting rates to rise in the next two years, which
equals one if the consumer (i) expects rates to be higher in the next 12 months (based on the
54
answer to question 2), and (ii) reports the level of the expected rate in two years (answer to
question 3b) greater than the level of the expected rate in one year (answer to question 3a).
An indicator for expecting rates to rise in the next five years is constructed similarly, equal
to one if the consumer meets conditions (i) and (ii), and reports the level of the expected rate
in five years (question 3c) greater than the level of the expected rate in two years (question
3b).
4. “Which, if any, of the following actions are you taking, or planning to take, in light of your
expectations for interest rates?” Select all that apply.
Bring forward major purchases (such as furniture or appliances)
Postpone major purchases
Cut back spending and save more
Pay debt
Take no action
We construct a series of indicators for taking a specific action.

Notes: Each cell presents the results from estimating one regression using equation (1). ** and *** denote significance
levels at 5% and 1%. Standard errors are clustered at the loan level. All regressions include a set of control variables
(see Section 3), month fixed effects, and loan fixed effects. Column (1) shows the responses of total monthly debt
service payments, which include scheduled mortgage payments (column 2) and required non-mortgage payments
(column 3). The latter consist of required payments on revolving debt (column 4) and on non-revolving debt (auto
and installment loans).
