OSFI cuts capital buffer to 3%, freeing C$74B for Canada's big banks

Canada's banking regulator cut its capital buffer by half a percentage point, releasing C$74 billion to spur lending as the economy faces recession risk.

Canada's banking regulator lowered the domestic stability buffer for the country's six largest banks to 3% from 3.5%, releasing C$74 billion in capital to support lending as the economy contracts.

"By lowering both the level and top end of the range of the domestic stability buffer, OSFI will enable the banking sector to deploy its excess capital in support of Canada's economic adaptation to new opportunities," Superintendent Peter Routledge said.

The change, effective immediately, reduces the expected common equity Tier 1 ratio for the six lenders by half a percentage point to 11%. The banks — Bank of Montreal, Bank of Nova Scotia, Canadian Imperial Bank of Commerce, National Bank of Canada, Royal Bank of Canada and Toronto-Dominion Bank — held CET1 ratios ranging from 13% to 14.3% as of the end of April, well above the new minimum. The regulator also lowered the top end of the buffer range by a full percentage point to 3%.

The move comes as Canada's economy shrank 0.1% in annualized terms in the first quarter after a 1% contraction in the final three months of 2025, raising the risk of a technical recession. Prime Minister Mark Carney's government is seeking to strengthen domestic investment and reduce reliance on the U.S., supported by major development projects in natural resources, infrastructure and defense. The C$74 billion in freed-up capital implies room for an expansion in risk-weighted assets of C$673 billion, giving the banks significant capacity to increase lending.

The buffer, introduced in 2018 to ensure systemic stability, is set twice annually based on household debt, asset imbalances and other financial trends. The regulator last raised it by half a percentage point in June 2023. At 3%, OSFI judged the buffer sufficient to absorb potential costs from a range of prudential vulnerabilities.

The Bank of Canada has held its benchmark interest rate unchanged at each of its last five policy meetings, though officials have said they remain ready to act if inflation broadens beyond gasoline and energy prices or trade is further disrupted by the renegotiation of the North American trade agreement.

Banks Welcome a Business-Friendly Ottawa

Bank executives have welcomed what they describe as a more supportive regulatory environment since Carney was elected on a platform of boosting exports beyond the U.S. and accelerating approval for major energy and infrastructure projects. Royal Bank of Canada Chief Executive Dave McKay said at a Bloomberg event in Toronto this week that there is a "risk on" environment for investing, helped by plans for port development, pipelines and the government's increasing defense spending. "I think you'll see some announcements coming soon, particularly on a number of pipelines, but we have to expedite that approval process because this capital that's excited about Canada will not wait," McKay said.

The capital buffer reduction shows that OSFI views the banking system as well-capitalized enough to absorb potential losses while also supporting economic growth. The six largest banks have continued to buy back shares and most have increased their quarterly dividend payouts, even as their CET1 ratios remained well above regulatory minimums. With C$74 billion in capital now available for deployment, the banks face pressure to channel funds into commercial and consumer lending rather than returning excess capital to shareholders.

Recession Risk Looms as Trade Uncertainty Persists

Canada's GDP contracted in back-to-back quarters for the first time since the pandemic-era downturn, though early data points to a rebound in activity in April. Hiring has recovered recently and exports have risen, but the economy faces structural challenges as the U.S. shifts trade policy and embraces tariffs, immigration slows and technologies like artificial intelligence reshape industries. The C$673 billion in potential risk-weighted asset expansion represents a substantial lever for the banks to support the economic transition.
