My final question--and I'm sorry I don't have more time--may be more for the afternoon panel.
The U.S. lawmakers, the ones who are concerned about the role of speculation, are saying there's two factors. One is that there were regulators in the past who put limits on the amount, in terms of how much they could have in terms of a commodity exchange, so you would limit the amount that happened, say, in a futures market over commodities like the price of crude. Second is the allowing of what are called private electronic platforms. So the U.S. lawmakers are saying these two things are causing the role of speculators to increase, driving up the price for their benefit, not to actually reflect market price.
I don't know whether you can touch on that. It may be a question for the afternoon panel, but do you want to touch on those two things, whether those two developments are perhaps things we ought to look at?
