This paper studies the hedging effectiveness of interest rate swaps using different reference rates for eliminating interest rate risk from floating rate loans. Two different reference rates are studied. The first is a reference rate whose maturity, ∆, matches the payment interval of the floating rate loan. The second is a reference rate whose maturity is ∆/N. The prime examples are LIBOR and SOFR, respectively. We show that the ∆-based interest rate swap provides a good static hedge, but the ∆/N-based swap does not. Although dynamic hedging with the ∆-based interest rate swap is possible under some conditions, it both introduces model risk and increases transaction costs, making it a less practical alternative.
