Frederick Kaufman explains how our daily bread has become fodder for Wall Street speculators, at Foreign Policy.com.

Since the bursting of the tech bubble in 2000, there has been a 50-fold increase in dollars invested in commodity index funds. To put the phenomenon in real terms: In 2003, the commodities futures market still totaled a sleepy $13 billion. But when the global financial crisis sent investors running scared in early 2008, and as dollars, pounds, and euros evaded investor confidence, commodities — including food — seemed like the last, best place for hedge, pension, and sovereign wealth funds to park their cash. “You had people who had no clue what commodities were all about suddenly buying commodities,” an analyst from the United States Department of Agriculture told me. In the first 55 days of 2008, speculators poured $55 billion into commodity markets, and by July, $318 billion was roiling the markets. Food inflation has remained steady since.

The money flowed, and the bankers were ready with a sparkling new casino of food derivatives.
