“This paper focuses on the pricing of variance and volatility swaps in the energy market. An explicit variance swap formula and a closed-form volatility swap formula (using the Brockhaus–Long approximation) for energy assets with stochastic volatility are found. These formulas follow the continuous-time generalized autoregressive conditional heteroskedasticity(1,1).GARCH.1; 1//model (meanreverting) or the Pilipovi´c one-factor model. A numerical example is presented for the AECO natural gas index.”
