What happened during the American financial crisis and could the stress test in Canada prevent the same crisis in Canada?
The American financial crisis, commonly referred to as the Global Financial Crisis (GFC) of 2007-2008, was a severe worldwide economic crisis that originated in the United States. The crisis had multiple causes and contributing factors, with significant impacts on the global economy. Key elements of the crisis included:
- Subprime Mortgage Lending: A significant factor was the widespread issuance of subprime mortgages in the U.S., which were loans made to borrowers with poor credit histories and a high risk of default.
- Housing Bubble: The U.S. experienced a housing bubble, where housing prices were driven to unsustainable levels due to speculative buying and easy credit.
- Securitization of Risky Mortgages: Many of these subprime mortgages were bundled into mortgage-backed securities (MBS) and sold to investors globally. The risks associated with these securities were often underestimated or not fully understood.
- Financial Derivatives: The use of complex financial derivatives, such as collateralized debt obligations (CDOs), amplified the risks. When homeowners began defaulting on their mortgages, the value of these securities plummeted.
- Bank Failures and Financial Institution Distress: The collapse of major financial institutions, notably Lehman Brothers, and the distress of others led to a severe credit crunch, impacting businesses and consumers worldwide.
- Government Intervention: The crisis prompted massive government interventions, including bailouts of financial institutions and stimulus packages to stabilize the economy.
Regarding the potential for the mortgage stress test in Canada to prevent a similar crisis, the stress test is designed to address some of the issues that contributed to the GFC:
1. Improved Lending Standards: The stress test ensures that borrowers are evaluated against higher interest rates, reducing the likelihood of lending to individuals who cannot afford their mortgage payments under different economic conditions.
2. Reducing Risk of Default: By ensuring that borrowers can withstand higher interest rates, the stress test aims to lower the risk of widespread mortgage defaults, a key issue in the GFC.
3. Financial System Resilience: The stress test contributes to the overall resilience of the financial system by promoting prudent lending practices and reducing the risk of a housing market collapse.
4. Consumer Protection: The stress test helps protect consumers from overextending themselves with mortgage debt, which was a significant problem in the U.S. leading up to the GFC.
Affordability Crisis
To prevent a similar crisis in Canada, stress tests (and there have been several) have exacerbated another problem for Canadians: they make housing more unaffordable and inflame Canada’s housing affordability crisis. With each new stress test, the maximum mortgage Canadians can get becomes less at the same time house prices increase, pushing many Canadians out of the housing market. To address this problem, the government changed its policy in 2024, and for the first time,e Canadians can obtain a larger mortgage. However, the maximum mortgage amount has returned to the 2018 levels, which is still grossly out of line with house prices today.
While the mortgage stress test in Canada is a valuable tool for promoting financial stability and responsible lending, it is not a guarantee against a financial crisis. A crisis can result from a complex interplay of various factors, including economic, regulatory, and market dynamics. The stress test is one of several measures needed to maintain a stable and sustainable financial system. Other factors, such as global economic conditions, regulatory oversight, and the behaviour of financial institutions and investors, also play critical roles in preventing a financial crisis.
