Market Manipulation

Has the world supply of oil been cut in half in the past year?
Has the demand for oil world wide increased by double in the past year? surely everyone knows neither case is true so what caused the price of oil to double since last year?
deregulation of the energies futures markets. congress had hearings 2 weeks ago to find out how they could stop the speculators from destroying our country by up bidding the price of oil not on the basis of supply and demand, but on hedging their bets. on unregulated gambling on the energies markets. no collateral needed just lots of money to keep reinvesting over and over till oil is up to what ever it can be.
In the hearing we found out that if the word "energy" were reintroduced into already existing commodities (things we need to survive as an economy) regulations, the price of oil would drop between 25% and 50% in one day. Why haven't they put that regulation back into the legislation? Republicans are stopping the legislation from going through. Filibustering.
