On December 12, the Basel Committee released a report on the “Recalibration of shocks for interest rate risk in the banking book,” as an adjustment to the Committee’s 2016 commitment to recalibrate the interest rate shock parameters.

The Committee began its calibration of interest rate shocks before the March 2023 banking issues transpired and is now following up on fundamental shortcomings in traditional risk management of banks, including interest rate risks. The report is brief and focuses on specified topics: for the first topic, the current calibration and methodology outlining current interest rate shocks (measured in basis points), the calculation of average interest rates from 2000 to 2015, the application of three tiers for shock parameters, and problems with the methodology; for the second topic, a proposal of a new methodology and calibration using a formula with outlined steps for countries to adopt, a comparison between the existing and new methodology, and a recalibration table; and, the third and final topic emphasizes additional issues and next steps, including caps, non-parallel shocks, and impact assessment.

The Committee noted in its press release that these changes “are needed to address problems with how the current methodology captures interest rate changes during periods when interest rates are close to zero.” Comments can be submitted to the Committee until March 28, 2024.
