26 MARCH / APRIL 2023 DIRECTORS / SENIOR MANAGEMENT Bank balance sheets were adversely affected in multiple ways by the speed and magnitude of the rising rate environment in 2022. Most noticeable was the effect on investment portfolios, which experienced significant depreciation in market value, some to the point where capital became severely stressed and access to liquidity restricted. The problems had nothing to do with asset quality, poor lending practices or anything credit related. They were entirely a function of the mathematics of rising interest rates. This fact and the lessons learned point out the critical importance of reliable tools and sound processes for managing liquidity and interest rate risk. Asset/liability management (ALM) is the coordinated process of defining, measuring and managing the financial risks faced by bank balance sheets including price risk, liquidity risk and interest rate risk. Interest rate risk specifically is the risk to earnings or capital arising from movements in interest rates. Bank managers most often focus on the risk to earnings and income rather than capital. Capital at risk, however, is an important point of focus for sound macro-management, and it’s something that warrants a deeper understanding. Managing capital at risk involves measurement of the economic value of equity (EVE). This concept gauges the impact of interest rate changes on fair market values of asset, liabilities and equity. Using discounted cash flows and standard valuation methodology, EVE captures the change in economic value of the bank even though that change may not be reflected in the bank’s accounting books and records. Consider the underlying market value of bonds in the investment portfolio. We all know that if interest rates rise, bond prices fall. This is the manifestation of price risk. If we’re focused only on bonds in isolation, though, we can’t know how the rate changes affect the overall economic value of the balance sheet. After all, loans and deposits also have an economic value just like bonds. If market interest rates rise sharply, then existing fixed-rate loans will be worth less from an economic standpoint. Indeed, any financial asset or liability – anything with a cash flow – will have an underlying value that fluctuates as interest rates move up and down. Whereas the value of assets will move inversely to interest rates, the value of liabilities will move directly with rates. This is because existing fixed rate deposits become more valuable to the institution if market interest rates rise. So how do we calculate economic value of equity? Remember from the standard accounting relationship that “assets = liabilities + owners’ equity.” If we can calculate the fair market value of assets and liabilities, then we can simply back into the value of equity capital. Moreover, if we can project the changed value of assets and liabilities under different rate environments, we can measure projected changes in EVE as well. This is precisely what we do when we measure interest rate risk from the economic perspective. Monitoring changes in the economic value of equity is valuable in that it provides a comprehensive meaRevisiting the Economic Value of Equity Asset/liability management in 2023 Jeffrey F.
