What I don't understand is why speculation is blamed for the oil prices.  Speculators can't receive the oil and knowing that, all they can do is contribute to volitility, since they don't consume the product and must sell at some point.  Also while we look hard at our own oil inventories, the price of oil is set globally.  So increases in our inventories can have the opposite effect that one might expect, because someone had to go without.

Here is another interesting article:

I agree BaSE.  Maybe your article had a bit of truth to it if they were talking about short-term movements, I couldn't really tell what their timeframe was.  I do some trading in the gold market, and there is no doubt in my mind that the gold market is being manipulated by...the central banks!  I have no doubt that they would do anything to keep the price of gold down, and the apparent value of their currencies up.  So, I wonder if this last plunge in the oil price wasn't caused by intense selling by folks like the Saudis.  Anything to keep the boat from rocking, but then again, I am so cynical that I shock myself sometimes.
