We price Asian options on commodity futures contracts in the presence of stochastic convenience yield and interest rates as well as jumps in the commodity spot price. We obtain a closed-form solution for the geometric average case without the presence of jumps. This analytic result enables us to apply suitable control variates to price an arithmetic average Asian option via Monte Carlo simulation. We observe a significant reduction in the size of confidence intervals. Varying the parameters of the model, we obtain a good understanding as to how option prices change accordingly. We then consider a variation of the model through adding jumps to the commodity spot price dynamics. By conditioning on the jump times first and then averaging over the sequences of jump times, we show that our control variate still leads to significant variance reduction, even though a closed form solution for a geometric average Asian option in the presence of jumps is unavailable.
