OSFI Capital Requirement Changes

OSFI releases its draft advisory regarding revised capital requirements for mortgage insurers, which came into effect January 1, 2017. The new requirements increased the amount of capital required to be held by mortgage insurers due to more drivers involved in the required capital formula. Some of the key determinants of the new capital requirements are:
* LTV and type of mortgage
* Credit score
* How long it has been since the credit score was last pulled
* The likelihood of a borrower’s credit score moving materially up or down
* Amortization period
* How long the mortgage insurance policy has been in force
* Which region the underlying home is located

The price changes represented an approximate 12%–15% increase to high-LTV mortgage insurance. Genworth MI Canada and Canada Guaranty followed suit and matched CMHC’s price increases.

OSFI Announces Final B-20 Guidelines

OSFI unveils its final B-20 guidelines regarding residential mortgage underwriting practices and procedures for federally regulated financial institutions. It includes a new stress test that would require potential borrowers to qualify for underwriting using the higher of their contracted mortgage rate + 200 bps or the 5-year benchmark fixed rate published by the Bank of Canada.

As part of OSFI’s final B-20 guidelines, federally regulated financial institutions are disallowed from arranging (or appearing to arrange) a mortgage or combination of mortgages secured by the same property that would circumvent the maximum LTV ratio as defined in a lender’s underwriting policies or legal requirements.

Finally, OSFI’s new B-20 guidelines introduce greater due diligence, including: intended use of loan (e.g., purchase, refinancing), type of purchase (owner-occupied, recreational, investment, etc.), and type of refinancing (if applicable).
