Abstract
Spread options are notoriously difficult to price without the use of Monte Carlo simulation.
Some strides have been made in recent years through the application of Fourier transform methods;
however, to date, these methods have only been applied to specific underlying processes including
two-factor geometric Brownian motion (gBm) and three-factor stochastic volatility models. In this
paper, we derive the characteristic function for the two-asset Heston–Hull–White model with a full
correlation matrix and apply the two-dimensional fast Fourier transform (FFT) method to price equity
spread options. Our findings suggest that the FFT is up to 50 times faster than Monte Carlo and yields
similar accuracy. Furthermore, stochastic interest rates can have a material impact on long-dated
out-of-the-money spread options.
