"Which measurements would you put highest priority on in 2024?"
I’d say that Net Interest Margin (NIM) changes and Economic Value of Equity (EVE) should continue to be the primary focus of IRR management in 2024. Gap calculations rarely give the full picture (focused on timing of reprice, and not magnitude), and Duration measurements can be difficult to understand. Given the extreme rate increases in the past two years and the bank failures in 2023, all financial institution managers and directors should have a clear understanding of how future market rate changes could impact both shorter-term earnings (aka the NIM in the next one and two years) and longer-term capital values (aka the EVE).
