Ras TanuraTo move the price of oil, you must first be able to move oil. The last tanker to leave Ras Tanura yesterday, it's belly full of cheap Saudi oil, triggered a spike upward in the price of oil as there was no other ships to follow it's example. The ability to move the price of oil is curtailed by the physical inability to get more oil from the port to sea. If you can't get a product to your customers, then the price matters not.
The vast majority of the oil leaving Ras Tanura will be a while seeing the inside of your gas tank. Oil storage is at a premium, and traders are taking advantage of contango in the oil space. Traders know that oil closer to the end of the year is going for $65, a nice premium to today's price of $45. They know that the storage fees will be less that the gain at the end of the game. Guaranteed profit. So all of this cheap oil is being sopped up, the glut going into storage.
Once the only oil moving to sea, or elsewhere, is oil coming from suppliers that don't share the Saudi lust for world power, then the price will spike upwads to reflect other agendas.
