Recent increases in commodity prices have led to calls for the regulation of speculators. These calls have come from many reputable quarters including leading agricultural and food policy institutions such as International Food Policy Research Institute as well as different members of the U.S. Congress. They are based on an assumption that speculative activities are a primary or major source of the volatility in the markets and that controlling these activities through regulations would bring more stability to the market. The paper tests this hypothesis and assesses the contribution of speculative activities in the commodity markets over the past decade to price inflation. The paper argues that government regulatory policies to control speculation in commodity markets is a second best solution that would probably yield neutral or negative benefits to the very people the policy aims to protect.
