Pricing and Hedging Interest Rate Options:Evidence from Cap-Floor Markets
AbstractWe examine the pricing and hedging performance of interest rate option pricing models using daily data on U.S. dollar cap and floor prices across both strike rates and maturities. Our results show that fitting the skew of the underlying interest rate probability distribution provides accurate pricing results within a one-factor framework. However, for hedging performance, introducing a second stochastic factor is more important than fitting the skew of the underlying distribution. This constitutes evidence against claims in the literature that correctly specified and calibrated one-factor models could replace multi-factor models for consistent pricing and hedging of interest rate contingent claims.
