The Office of the Superintendent of Financial Institutions (OSFI) issued this guideline to establish large exposure limits for Domestic Systemically Important Banks (D-SIBs) on a consolidated basis. It mandates that D-SIBs cap aggregate exposures to single counterparties or connected groups at 15%, 20%, or 25% of Tier 1 Capital depending on the counterparty's status, while requiring timely reporting and robust internal risk management processes. The framework also details specific exemptions for government exposures, high-quality liquid assets, and central counterparties, alongside precise measurement rules for banking book, trading book, and structured vehicle exposures.
