Duration Hedging as a Shield Against Rising Interest Rates

The strategy game Risk, where players attempt to capture each other’s territories until the final player occupies all 42 territories on the board, was originally invented by a French filmmaker in 1957. The French version was aptly called La Conquête du Monde, or The Conquest of the World. Parker Brothers purchased the rights to the game in 1959, and thus Risk was born. Risk is widely considered to be the blueprint for later war-and-strategy games for multiple players and requires players to plan ahead and think strategically in order to win. Financial institutions must use similar tactics to manage their own risk, especially when it comes to interest rate risk. To help manage it, financial institutions can employ duration hedging — typically with investments and/or other financial products that hedge against the effects of interest rate swings on longer-duration bonds. Duration hedging is common practice at big financial institutions, but its use is less frequent elsewhere, particularly among community financial institutions (CFIs).One common barrier to hedging for CFIs managing these programs in-house is that it requires a lot of attention and staff to run such a program effectively on their own. In addition, a hedge carries its own costs and reduces the income from the underlying securities that are being hedged. For these reasons, having a correspondent bank partner the CFI can count on to help manage the logistics of a hedged loan is the most viable option for offering duration hedging.A recent paper written by four university scholars that looked at one duration hedging method — interest rate swaps — during the run-up in interest rates in 2022 found that more than three-quarters of financial institutions never used them. Financial institutions that were most exposed to interest rate risks had used even less hedging than others. Defining Duration HedgingSo, what is duration hedging exactly? It is a strategy to reduce interest rate risk. One of the key ways that financial institutions manage their held capital is through bond investment to earn interest. The longer the bonds, the greater the risk of loss if interest rates rise. In the case of Silicon Valley Bank last March, that institution had a high balance of deposits that it invested in fixed-interest, longer-term bonds just as the Fed began hiking interest rates. They had planned to hold those bonds until they matured, but that proved to be a billion-dollar mistake, as interest rates rose sharply and the bank run occurred before the bonds matured.Duration Hedging StrategiesTo guard against these types of interest rate swings, there are a number of established duration hedging strategies that CFIs should consider:

Investing in longer-term bonds is a standard way of managing cash for financial institutions, but those instruments are subject to interest rate risks that can be serious. Duration hedging can help dampen those risks and could be well worth the resources it takes to devise such a system.
