The degree of comovement in commodity futures curves intensifies during periods of financial and macroeconomic turmoil and increased geopolitical risk. In contrast, our analysis shows that the gold futures market becomes more backwardated (contangoed) when the rest of the commodity futures markets become more contangoed (backwardated).\n"]
