OPEC and all the speculators jack up prices at any opportunity. It's disgusting.

The only way to stop that is to force the person or firm "buying" the commodity to actually take possession of the barrels. Then watch how quick the shenanigans stop. It's ridiculous that a shipment of oil can be bought and sold 20 times before it reaches port. It's always going to end up at a refinery anyway. Everyone in the middle are just scumbags manipulating the prices for personal gain.
