There is now a growing discomfort about the role of speculative finance in the US, the capital of global finance. In an open letter addressed to all airline customers, leaders of airlines in the US have recently requested the passengers to join them in pushing legislation to add more transparency and disclosure in the oil markets. 

They argue that "twenty years ago, 21% of oil contracts were purchased by speculators who trade oil on paper with no intention of ever taking delivery. Today, oil speculators purchase 66% of all oil futures contracts, and that reflects just the transactions that are known.

Speculators buy up large amounts of oil and then sell it to each other again and again. A barrel of oil may trade 20-plus times before it is delivered and used; the price goes up with each trade and consumers pick up the final tab. Some market experts estimate that current prices reflect as much as $30 to $60 per barrel in unnecessary speculative costs."  Speculators have indeed sharply increased their allocation to commodity markets from $13 billion in 2003 to $260 billion in 2008 and at present they are not adequately constrained by rules about margin requirements and other regulations about buying and selling which apply to equity trades. In fact, there has been further deregulation in the US in recent years with respect to speculative futures trading in oil and commodity indices covering a wide spectrum of commodities including food and metals.

Eminent financiers such as George Soros and powerful US senators, such as Joe Lieberman, are arguing that commodity index speculators are a big part of the increase in commodity prices. Michael Masters, a hedge fund manager in his testimony before the US Congress, has said that gasoline prices could fall to $2 a gallon, half of today's price with legislation barring commodity index funds. There are now more than 10 legislative proposals before the US Congress calling for better regulation of commodity index markets.
