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.

Housing Affordability and Parental Income Support

In many countries, the cost of housing has greatly outpaced income growth, leading to a housing affordability crisis. Leveraging Canadian loan-level data and quasi-experimental variation in payment-to-income constraints, we document an increasing reliance of first-time homebuyers on financial help from their parents, through mortgage co-signing. We show that parental support can effectively relax borrowing constraints—potentially to riskier borrowers.

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.

The Ecology of Automated Market Makers

Staff Discussion Paper 2024-12 Annetta Ho, Cosmin Cazan, Andrew Schrumm
This paper describes the ecology of automated market makers, which are the most popular decentralized exchange model for the pricing and trading of crypto assets within decentralized finance.

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.

Financial Intermediation and Fire Sales with Liquidity Risk Pricing

Staff Working Paper 2024-18 Yuteng Cheng, Roberto Robatto
We provide a theory of fire sales in which potential buyers are subject to liquidity shocks and frictions that limit their ability to resell assets. Viewed through the lens of the model, the liquidity requirements proposed by the U. S. Securities and Exchange Commission for these intermediaries could hurt the economy.

Finding a Needle in a Haystack: A Machine Learning Framework for Anomaly Detection in Payment Systems

Staff Working Paper 2024-15 Ajit Desai, Anneke Kosse, Jacob Sharples
Our layered machine learning framework can enhance real-time transaction monitoring in high-value payment systems, which are a central piece of a country’s financial infrastructure. When tested on data from Canadian payment systems, it demonstrated potential for accurately identifying anomalous transactions. This framework could help improve cyber and operational resilience of payment systems.
