Do you trust that large banks can remain stable during a major stock market crash?
Moody's Ratings identified a stock market crash as the primary credit risk for large Canadian banks in an analysis published Wednesday, October 21, 2026. The report examined how market-driven revenue sources leave major institutions vulnerable to economic downturns.
Why it matters
A market crash decreases revenues from wealth management, asset management, and retail brokerage, which directly threatens the profitability of major financial institutions. Understanding these risk factors is essential to assessing the stability of the broader Canadian banking sector.
Moody's Ratings analyzed the Big Six banks across 9 credit risk scenarios. Institutions such as Royal Bank of Canada, Toronto-Dominion Bank, and National Bank of Canada generate at least 20 percent of their revenue from market-driven sources.
The players

Royal Bank of Canada
As Canada's largest bank by market capitalization, it is a key focus of the report regarding market-driven revenue.
Toronto-Dominion Bank
This major financial institution is noted for both its market-driven revenue and its exposure to consumer credit card and auto loan defaults.
National Bank of Canada
This bank is highlighted as one of the institutions deriving at least 20 percent of its revenue from market-driven sources.
Equitable Bank
This financial institution is identified in the report for its specific high exposure to real estate market stress.
The details
The report highlights that trading volumes and fees tied to market valuations decline sharply during a crash, pressuring institutions with significant exposure. While Equitable Bank faces risks from real estate stress, Toronto-Dominion Bank remains highly exposed to consumer defaults.

Market Dynamics
This risk assessment functions alongside the Basel III capital requirements by highlighting specific market vulnerabilities that current regulatory frameworks are designed to mitigate. The findings underscore how modern banking revenue models are increasingly tethered to equity market fluctuations.
Retail investors should consider how market-driven revenue concentration at institutions like Royal Bank of Canada or Toronto-Dominion Bank might affect dividend stability during downturns. These findings suggest that bank portfolios may be more sensitive to equity volatility than historical interest-rate-dependent models might imply.
The takeaway
Investors should diversify their exposure across sectors to mitigate risks associated with banks that rely heavily on market-driven fees. Monitoring these credit risk reports can help individuals better gauge the resilience of their personal banking and investment choices.
