• The Optimum Quantity of Central Bank Reserves

  Staff Working Paper 2025-15 Jonathan Witmer

  This paper analyzes the optimal quantity of central bank reserves in an economy where reserves and other financial assets provide liquidity benefits. Using a static model, I derive a constrained Friedman rule that characterizes the socially optimal level of reserves, demonstrating that this quantity is neither necessarily large nor small but depends on the marginal benefits of reserves relative to alternative safe assets.

• Stress testing central counterparties for resolution planning

  Staff Analytical Note 2025-11 Katherine Brennan, Bo Young Chang, Alper Odabasioglu, Radoslav Raykov

  The Bank of Canada completed its first resolution plan for the Canadian Derivatives and Clearing Corporation (CDCC) in 2024. To estimate the resolution costs, we apply the extreme value theory method to simulate the credit losses that would result from extreme scenarios where multiple clearing members default at the same time.

• The Prudential Toolkit with Shadow Banking

  Staff Working Paper 2025-9 Kinda Hachem, Martin Kuncl

  Can regulators keep pace with banks’ creative regulatory workarounds? Our analysis unpacks the trade-offs between fixed regulations and crisis-triggered rules, showing that the latter are especially prone to circumvention—and can trigger larger, costlier bailouts.

• Effects of macroprudential policy announcements on perceptions of systemic risks

  Staff Analytical Note 2025-4 Thibaut Duprey, Victoria Fernandes, Kerem Tuzcuoglu, Ruhani Walia

  We introduce a history of macroprudential policy (MPP) events in Canada since the 1980s. We document the short-run effects of MPP announcements on market-based measures of systemic risk and find that MPPs can influence the market’s perception of large banks’ resilience.

• Mortgage stress tests and household financial resilience under monetary policy tightening

  Staff Analytical Note 2024-25 Jonathan Hartley, Nuno Paixão

  This note analyzes mortgage stress tests, a macroprudential tool. We find that when mortgage stress tests are applied to all mortgage purchase originations, they improve credit quality and reduce credit and house price growth. They also improve the resilience of borrowers to financial shocks, such as the large increase in interest rates during 2022–23.

• Entry and Exit in Treasury Auctions

  Staff Working Paper 2024-29 Jason Allen, Ali Hortaçsu, Eric Richert, Milena Wittwer

  This paper introduces and estimates a structural model of the Canadian primary market for government debt. We assess the role of dealer exit in this market as a key reason for increased, yet irregular, customer entry and quantify the benefits of greater customer competition against the costs of higher market volatility.

• Credit Card Minimum Payment Restrictions

  Staff Working Paper 2024-26 Jason Allen, Michael Boutros, Benedict Guttman-Kenney

  We study a government policy that restricts repayment choices with the aim of reducing credit card debt and estimate its effects by applying a difference-in-differences methodology to comprehensive credit-reporting data about Canadian consumers. We find the policy has trade-offs: reducing revolving debt comes at a cost of reducing credit access, and potentially increasing delinquency.

• Assessing the Impact of the Bank of Canada’s Government Bond Purchases

  Staff Discussion Paper 2024-5 Chinara Azizova, Jonathan Witmer, Xu Zhang

  In March 2020, the Bank of Canada implemented the Government of Canada Bond Purchase Program, eventually purchasing approximately $340 billion of government bonds. In this paper, we analyze the impact of this program on financial market prices and yields as well as on GDP and inflation.
