Have a look at this article: http://www.philstockworld.com/2008/05/26/OilManipulationsExposed/ "Many traders have moved to the unregulated over-the-counter exchanges that do not require companies like ExxonMobil or Goldman Sachs & Co. to disclose information about trades. "The lack of information on prices and large positions in OTC markets makes it difficult in many instances, if not impossible in practice, to determine whether traders have manipulated crude oil price," said Tyson Slocum, research director at Public Citizen[..]" "At the peak of June trading there were close to 450,000 open contracts but the NYMEX allows traders to "roll" open contracts to longer months WITHOUT PENALTY and by the close of the June contracts, less than 30,000 contracts (30M barrels) were actually finalized for delivery. The other 420M barrels that were, at some point, contracted to be delivered in June, were "rolled" into July, August, Sept.. contracts[..] Notice how there are 378,974 barrels "ordered" for July and 91,509 for Aug and 94,177 for Sept and 49,177 for Oct. I will tell you for a fact, right now, that on June 24th (close of July trading) there will be LESS than 40,000 contracts accepted for delivery. All but 40M of the now 378M barrels that could be delivered to the US PER THE EXISTING CONTRACTS will be cancelled by these evil manipulative bastards in oder to create an artificial shortage of oil each month while driving up the apparent demand for the next month by rolling the contracts forward. Thatâs how the scam works."
