My thoughts are that if the Gov. is(or was) pulling light sweet out of the SPR and putting into the open market to try to put a cap on prices then they are incredibly stupid, replacing it with heavy sour nonetheless.
My original point in posting the article was to point out that it is possible that Gov. has its hands in "free" markets and some markets are in fact manipulated. According to the article it is Gold and Oil. Ultimately, I believe, that any commodity thats price is manipulated can only be done so for so long until a drastic repricing, or rebalancing if you will, occurs. It could go on for years, technically, but at some point the facade falls and true price rationing will occur.
