OSFI maintains the level of the Domestic Stability Buffer at 3.50% – Letter (June 2025)

To: Domestic Systemically Important Banks (D-SIBs)^{Footnote 1}

Following its semi-annual review, OSFI has decided to maintain the level of the Domestic Stability Buffer (DSB) at 3.5% of total risk-weighted assets as calculated under the Capital Adequacy Requirements (CAR) Guideline. The current DSB level came into effect on November 1, 2023. We expect D-SIBs to continue to target a Common Equity Tier 1 ratio of at least 11.5% of total risk-weighted assets.

The decision to maintain the DSB at 3.5% reflects our current assessment that systemic vulnerabilities have been stable, while near-term risks are rising but still low. In this context, we expect D-SIBs to exercise heightened prudence in their capital management practices.

OSFI remains committed to reviewing the DSB regularly to ensure that it contributes to the safety and soundness of Canada’s financial system while supporting public confidence. We continue to monitor the uncertainty in the risk environment, and we stand ready to reduce the DSB as conditions warrant.
