A thorough and in-depth review of the interest rate risk policy is performed to ensure regulatory adherence and completeness of the IRR modeling and management program. This includes reviewing other related policies where they relate to interest rate risk management. This review is performed in consideration of the credit union’s asset size, complexity, and balance sheet interest rate risk profile.
The overall interest rate risk management governance framework is reviewed, including roles and responsibilities of the board, ALCO, and senior management. This coincides with testing governance requirements as identified through policy.
A review of the IRR measurement process, including a detailed evaluation of modeling inputs (data capture, integrity, and accuracy), model setup (chart of account level of disaggregation and a review of chart of account characteristics), model processing (including a review of IRR characteristic behaviors and measurement calculation), and outputs (a review of measurement output results relative to expected balance sheet characteristics and interest rate risk measurement monitoring), is completed. This review also incorporates overall modeling functional adequacy relative to balance sheet complexity. This includes a review of interest rate risk measurements utilized and their associated calculations, output reporting, and monitoring.
A review of the modeling assumptions utilized, including how well they reflect balance sheet behaviors, their derivations, and industry/peer expectations and comparisons. These generally include, but are not limited to, forecasted volumes, forecasted new/repricing rates, prepayments, rate sensitivities, indeterminate account average life estimates, lagging behaviors, rate drivers and spreads, and implied cap/floor behaviors. Major assumptions will be evaluated relative to their origin and industry/peer comparisons. Their periodic review, sensitivity/stress testing, change control management, and support will also be evaluated.
Controls are essential to a consistent and effective program. This review will include both operational and governance controls in the IRR modeling and management process. An evaluation of controls adequacy and consistency and aspects of operational and governance controls will be tested. Governance control evaluations will include reviewing and testing the reporting framework process to management, the ALCO, and the board. This will be tested through historical committee meeting documentation. Operational controls will be evaluated by reviewing the modeling process, including a review of procedures and a reconciliation of input data, particularly current position data accuracy. This will also include a review of how well the reports are utilized in managerial decision-making.
A back test will be performed on the NII simulation results from a previous period. This will include a major balance sheet category comparison of model results to actual results and a rate/volume variance analysis of the differences. This will also include reasonable explanations of the variances or modeling aspects that may need to be reviewed due to unexplainable and unreasonable variances.
A preliminary written and graphical report detailing the review conducted for each subsection will be delivered for the credit union’s review. Subsections are taken from regulatory guidance for an IRR management program review. Subsections may include either Recommendations, Considerations, or Comments. Recommendations tend to be more material or regulatory-driven to the program’s effectiveness. Considerations are suggestions to adhere to the industry’s best practices. Comments are generally consultative in nature and may pertain to the current regulatory or interest rate environment.
A preliminary report will be provided to allow the credit union the opportunity to address items and discuss them with a consultant. Credit union input is welcome as the goal of the engagement is to not only check the regulatory box but also provide value-added benefits to the credit union. The credit union will generally have the final review/edit to achieve a final report as the engagement is viewed as a collaborative effort with the credit union. We are here to work with you and provide support, not against you!
