✦ Synopsis


This article presents a reduced-form, two-factor model to price commodity derivatives, which generalizes the model by Schwartz and Smith (2000). The model allows for two mean-reverting stochastic factors and therefore implies that spot and futures prices can be stationary. An empirical study for the crude oil market tests the new model. Out-of-sample pricing and hedging results for futures and forwards show that the new model dominates the nonstationary model by Schwartz and Smith in the following sense: It works equally well for short-term contracts but leads to major improvements for long-term contracts. This finding is particularly relevant for typical applications like the valuation of commodity-linked real assets with long maturities.
