Which prior levels? No they won't be hitting $10 again, bt in 2-4 years time it is quite feasible that they could be back in the $40-60 range. Recession does wonders for conservation, as well as do high prices. They also encourage alternative fuels. In the next few years a LOT of new oil is coming onstream and that too will temper prices. When you consider that at least a quarter of the current runup is due to pure speculation, and another quarter to a weakened dollar, this is a quite realistic expectation. Things are irrational at the moment..........a Nigerian fires a rifle at a pipeline and oil jumps $6 a barrel. Scottish pipeline workers strike for 10 hours and it jumps $12 in two days, etc.......speculation rules the roost and it could all come crashing down.
