Two economists at the St. Louis Federal Reserve have published findings that indicate that Wall Street speculation is responsible for 15 percent of the increase in oil prices over the past decade, a finding with significant implications for the recent sharp rise in gas prices.
While politicians have little ability to alter the price swings of commodities like oil, regulators have both the authority and policy tools to do so. The Commodity Futures Trading Commission is responsible for overseeing the financial market for oil. The 2010 Wall Street reform bill gave the CFTC new power to limit excessive speculation, but the rule will not go into effect until later this year.

Commodity indexes allow speculators to bet on the price of several commodities at once, and have become very popular investment tools for both Wall Street investment companies and pension funds. Between 2004 and 2008, the total volume of trading activity in commodity indexes jumped from $13 billion to about $260 billion, according to research by Michael Masters, founder of Masters Capital Markets and the financial reform nonprofit Better Markets.
Masters and others have noted that speculation can exaggerate price swings otherwise dictated by fundamental supply-and-demand dynamics, and can also force prices to move contrary to supply-and-demand predictions. During 2008, when oil prices soared to their highest level on record, they did so during a period in which global demand was low and global supply was high — what should have been a recipe for lower prices.
