Canada’s federal banking regulator has announced that it will keep the Domestic Stability Buffer (DSB) unchanged at 3.5 per cent, signaling confidence that the country’s major banks are resilient in the current economic environment but that vulnerabilities remain elevated. This buffer is an additional layer of capital that Canada’s six largest, systemically important banks are required to hold so they can absorb losses and continue lending through periods of stress.

The regulator, the Office of the Superintendent of Financial Institutions (OSFI), conducts a review of the DSB twice a year — in June and December — and assesses the broader risk landscape before deciding whether to adjust the level. By maintaining the buffer at 3.5 per cent, OSFI is indicating that while risks such as high household debt and corporate credit vulnerability remain, they are currently stable enough that an increase is not warranted.

OSFI also noted that Canadian banks are holding capital well above regulatory minimums, with strong common equity ratios providing a substantial cushion against potential losses. This buffer helps ensure that lenders can continue providing credit to consumers and businesses even during financial disruptions, supporting economic stability.

Household debt has been a particular concern for regulators, as high levels of borrowing relative to income mean that shifts in interest rates or economic conditions could strain borrowers’ ability to service debts. Likewise, corporate debt growth has moderated but credit quality could be affected if trade-related challenges intensify. Despite these vulnerabilities, OSFI judges that the financial system’s overall capital position remains adequate.

Keeping the DSB steady at this level also helps avoid adding unnecessary strain on bank lending at a time when broader economic growth is modest. A higher buffer would require banks to hold even more capital, which can constrain lending capacity and economic activity. Should systemic vulnerabilities worsen appreciably, however, the regulator has the flexibility to raise the buffer to reinforce the banking system’s shock absorption capacity.

In practical terms for Canadians, this decision means that major banks are being encouraged to maintain strong capital positions without overly restricting credit. The move strikes a balance between safeguarding the financial system and supporting ongoing lending activity, contributing to broader financial stability heading into 2026.
