I agree it would raise the price.
May I just rebut one thing Ms. Savage said?
An example of the disconnect that can occur between the physical market and the futures market happened some time in 2007. The New York Mercantile Exchange trades a crude called WTI, West Texas Intermediate--the commodity crude--and it is physically produced in Texas. It's used in refineries in and around that area. There were major problems with a couple of refineries in that area, and that crude could not escape that particular market so it couldn't get out. There was tremendous pressure downward on that crude.
Another crude is Brent, which is produced in the North Sea. The typical spread is $2 in WTI's favour. It went to $8 to $10 in Brent's favour. So if there were speculators playing with it, they would have kept WTI up and the rest would have gone up with it.
