Interest rate risk in long‐dated commodity options positions: To hedge or not to hedge?

We empirically assess hedging interest rate risk beyond the conventional delta, gamma, and vega hedges in long‐dated crude oil options positions. Using factor hedging in a model featuring stochastic interest rates and stochastic volatility, interest rate hedges consistently provide an improvement beyond delta, gamma, and vega hedges. Under high interest rate volatility and/or when a rolling hedge is used, combining interest rate and delta hedging improves performance by up to four percentage points over the common hedges of gamma and/or vega. Thus, contrary to common practice, hedging interest rate risk should have priority over these “second‐order” hedges.
