Abstract

The sharp raise of the price of agricultural commodities between 2006 and 2008 seems to have a rationalization that goes beyond the mere interaction between supply and demand. Data evidence suggests that financial factors, rather than real determinants, played an important role in determining the dynamics of agricultural commodity prices. In particular, there seems to be a common source underlying food price changes and the financial markets dynamics. Evidence based on principal components supports the view that large fluctuations of food commodity prices can be related to portfolios adjustments of financial agents. We find robust evidence of a strong inverse correlation between financial markets’ returns and the movements of food commodity prices. Moreover, such an inverse relationship has clearly emerged during the recent financial crisis.
