I gotta weigh in on this one. I've been debating with others for months that this isn't a real supply-and-demand problem. Despite popular belief, oil supplies have been outpacing demand for some time. The price of oil is speculation-driven, set by the billions of dollars flooding the commodities market. I understand the "risk premium" built into the price of crude--but why does it still go up when the market encounters a problem? Isn't the risk already built in? Here's a link to a bipartisan report (Levin, D-MI and Coleman, R-MN) talking about the role of market speculation and lack of goverment oversight (due to the CFMA of 2000), and below it are a couple more links that may be of interest.
