The article looks at how commodity futures can help predict the value of commodity currencies. While past studies found that changes in commodity prices weren't great at predicting currency returns, this new research suggests that the basis of certain commodities can be useful for forecasting. The basis of commodities with high storage costs seems to be particularly helpful. This is because high storage costs make the basis more sensitive to changes in commodity risk, giving insight into the risk premium for commodity currencies. By combining different forecasting methods, the researchers were able to make the most of this information.
