The Office of the Superintendent of Financial Institutions (OSFI released the final version of the capital adequacy requirements guideline for the big banks on Tuesday.

The updated requirements are due to take effect in the first quarter of 2019.

The final version incorporates the standardized approach to counterparty credit risk for calculating derivatives exposures, which replaces the current method for computing that risk. It also includes changes to the treatment of securitized assets, among other changes.

OSFI has also finalized its changes to the capital requirements for bank exposures to central counterparties and the securitization framework.

In addition, the revised guideline includes changes to the capital floor and eliminates certain transition arrangements.

OSFI notes that it will consult separately on the latest reforms to the capital adequacy framework for global banks, known as Basel III, which features further revisions to the leverage ratio requirements, including a buffer for global systemically important banks and other technical amendments.
