The Office of the Superintendent of Financial Institutions (OSFI) requires domestic systemically important banks to maintain a minimum 21.5% Parental Stand-Alone Total Loss Absorbing Capacity ratio on a standalone legal entity basis. The framework calculates this risk-based ratio by adjusting consolidated capital and risk-weighted assets for foreign subsidiaries, branches, guarantees, and non-regulated entities to verify the parent's capacity as a source of strength. Implemented on November 1, 2023, the guideline ensures orderly resolution of non-viable banks while protecting depositors, policyholders, and senior creditors from financial sector instability.
