Although interest rates fluctuate randomly, many option-pricing models do not fully take into account their stochastic nature because of their generally limited impact on option prices. However, stochastic changes in stochastic interest rates may exert a significant impact on option prices when issues of maturity, hedging, or stochastic volatility are considered. This study incorporates the term structure of a stochastic interest rate driven by a Hull-White process into a stochastic volatility model in order to assess the sensitivity of option prices to changes in interest rate. It demonstrates that a stochastic volatility model with a stochastic interest rate outperforms a model with a constant interest rate, particularly, for short time-to-maturity European options.
