Commodity prices, commodity currencies, and global economic developments
In this paper, we seek to produce forecasts of commodity price movements that can systematically improve on naive statistical benchmarks. We revisit how well changes in commodity currencies perform as potential efficient predictors of commodity prices, a view emphasized in the recent literature. In addition, we consider different types of factor-augmented models that use information from a large data set containing a variety of indicators of supply and demand conditions across major developed and developing countries. These factor-augmented models use either standard principal components or ...

The key ...

First, I show that the comovement between metals with and without futures contracts has not weakened in recent years as speculative activity has risen. Specifically, the annual and quarterly price growth rates of the two metal categories have been positively correlated with their growth rates experiencing a structural shift by the ...
