OSFI revised the Guideline B-12 on interest rate risk management and published impact analysis statement on the guideline. The guideline provides a risk control framework for deposit-taking institutions to follow in identifying, assessing, and managing their interest rate risk. The revised version of Guideline B-12 will take effect from January 01, 2020 for domestic systemically important banks (D-SIBs) and from January 01, 2021 for other deposit-taking institutions. The current version of Guideline B-12 remains effective for non-D-SIBs until December 31, 2020.
OSFI had, in October 2018, issued a public consultation on revisions to the guideline on the interest rate risk in the banking book (IRRBB). The cover letter to the final guideline contains a summary of material comments received from stakeholders and an explanation of how they have been addressed. The key updates to OSFI Guideline B-12 include the following:
- Additional guidance for the IRRBB governance processes of institutions
- Expectations for the measurement of IRRBB, the development of stress and shock scenarios, and the key behavioral and modeling assumptions institutions should consider
- Introduction of an outlier/materiality test that compares the maximum loss of an institution to its capital base under the prescribed scenarios
The updated guideline reflects international sound practices, as outlined in the 2016 BCBS framework for IRRBB. The OSFI guideline incorporates most of the BCBS guidance to reflect changes in the market; the methods expected to be used by deposit-taking institutions for measuring, managing, and monitoring IRRBB; and updates related to supervisory practices. The revised expectations will ensure that the OSFI standards for measuring and monitoring IRRBB are comprehensive and reflect sound practices. OSFI's application of the Guideline B-12 will be commensurate with each institution's nature, size, business, and complexity as well as its structure, economic significance, and the level of inherent interest rate risk.
Effective Date: January 01, 2020 (D-SIBs); January 01, 2021 (Others)
