@H2O MAN,
Well, prices are off. There could be other reasons, but it doesn't look like a sudden worldwide surge in production. It could certainly be the case that a barrel dumped on the market affects the futures prices of many barrels. It's the nature of that part of the market to be highly leveraged.
I don't know. If it knocked out the speculative influence, we may be able to buy it back for less. Maybe, of course, means exactly the same as maybe not. Should we only consider the taxpayers' price of replacing it, or should we also consider the economic benefits of lower fuel prices?
