The current surge in gas prices has almost nothing to do with energy policy. It doesn't even have much to do with global supply and demand. It has most to do with America's continuing failure to adequately regulate Wall Street. Oil supplies aren't being squeezed. Over 80 percent of America's energy needs are now being satisfied by domestic supplies. In fact, we're starting to become an energy exporter. Demand for oil isn't rising. Oil demand in the U.S. is down compared to last year at this time. The American economy is showing only the faintest signs of recovery. Meanwhile, global demand is still moderate. Europe's debt crisis hasn't gone away. China's growth continues to slow. But Wall Street is betting on higher oil prices. Hedge-fund managers and traders assume that mounting tensions in the Middle East will hobble supplies later this year. Wall Street speculators also assume global demand for oil will rise in the coming year. These are just expectations, not today's realities. But they're pushing up oil prices just the same, because Wall Street firms and other big financial players now dominate oil trading. Where there's money to be made, Wall Street will find a way of making it. And when it comes to oil, so much money is at stake that gigantic sums can be made if the bets pay off. Speculators figure they can hedge against bad bets. Financial speculators historically accounted for about 30 percent of oil contracts, producers and end users for about 70 percent. But today speculators account for 64 percent of all contracts.
