Quote from spidey:
They are cornering the market. Enron pulled this trick in California. Oil bulls never mention how since the futures markets were de-regulated a few years ago, this is when we have seen the runup in commodities. There is no shortage of oil, wheat, corn, etc. so why are prices rising? This is pure manipulation, and it's being done via sophisticated methods, between parties utilizing Nymex, Ice and Dubai exchanges. They basically trade back and forth with each other, as well as accumulate positions.
