It is commonly asserted that speculative buying by index funds in commodity futures and over-the–counter derivatives markets created a “bubble“ in commodity prices, with the result that prices, and crude oil prices, in particular, far exceeded fundamental values at the peak. The purpose of this paper is to show that the bubble argument simply does not withstand close scrutiny. Four main points are explored. First, the arguments of bubble proponents are conceptually flawed and reflect fundamental and basic misunderstandings of how commodity futures markets actually work. Second, a number of facts about the situation in commodity markets are inconsistent with the existence of a substantial bubble in commodity prices. Third, available statistical evidence does not indicate that positions for any group in commodity futures markets, including long-only index funds, consistently lead futures price changes. Fourth, there is a historical pattern of attacks upon speculation during periods of extreme market volatility.

Long-only commodity index funds have been blamed by other futures market participants for inflating commodity prices, increasing market volatility, and distorting historical price relationships. Much of this criticism is leveled without any formal empirical support or even cursory data analyses. The Commodity Futures Trading Commission makes available the positions held by index funds and other large traders in their Commitment's of Traders report. In this research, we make an initial assessment of the size and activity of index funds in traditional agricultural futures markets. The results suggest that after an initial surge from early 2004 through mid-2005, index fund positions have stabilized as a percent of total open interest. Speculative measures-such as Working's T-suggest that long-only funds may provide a benefit in markets traditionally dominated by short hedging.
