Abstract

We propose a novel measure of the basis, namely the relative basis, as a more precise measure of the convenience yield on commodity markets. The relative basis is defined as the difference between the traditional basis, which is based on the first- and second-nearby futures prices, and a similarly-defined longer-term basis that is based on the second- and third-nearby futures contracts. We argue that the relative basis is a better proxy for the convenience yield because it excludes components in the traditional basis that are related to storage and financing costs. We find that the relative basis exhibits significant return predictability on commodity futures markets — it can subsume the traditional basis in forecasting commodity futures returns in both return predicting regressions and factor portfolio tests. Our empirical findings are robust to a variety of robustness tests and provide strong support to the Theory of Storage on commodity markets.
