Hedging Interest Rate Risk With Real And Nominal Treasury Yields

 | Nov 09, 2022 00:45

The recent rise in real yields for inflation-indexed Treasuries (TIPS) looks compelling for locking in relatively attractive payout rates, but the usual risks with bonds still applies. That inspires looking at a somewhat unorthodox strategy of holding TIPS and conventional Treasuries as a hedging strategy.

The issue is that while buying and holding a TIPS security when it offers a comparatively attractive positive real yield is tough to ignore, there’s no way of knowing if that payout rate will rise further (or fall) in the future. For example, buying a 5-year TIPS currently offers a 1.72% real yield (as of Nov. 7). Buying and holding through maturity guarantees that you’ll earn that rate. The question is whether higher or lower real yields await? No one knows, but one way to mitigate the risk is by diversifying the allocation to a 5-year maturity with an equal mix of real and nominal yields. (A similar case applies to other maturities, but we’ll use 5-Year Treasury as an illustration.)

The logic here is that real and nominal Treasury securities are complimentary in that the former offers a constant real yield with a fluctuating nominal yield. By contrast, standard Treasuries offer the opposite: a constant nominal yield and a fluctuating real yield. By holding both securities you tap into both features. Does the combination offer a stronger risk-adjusted profile than holding either Treasury security alone? To explore the possibility consider how an equal weight of real and nominal yields compares with the components in isolation for the 5-year maturity.
