Is gasoline gas price commodity speculation and fuel oil speculation more responsible for prices than oil ?

Sounds a lot like the price of housing a couple of years ago.And of course the Internet stocks a bunch of years ago.It is coming close to the end though,when the price goes up daily , no matter what happens,it is becoming irrational.A pipeline carrying 70,000 barrels a day is stopped and the price goes up $3.00 a barrel.It's just a matter of time and the price will fall and the drop will be rapid.
