Your Republican presidential nominee today, according to his prepared remarks on oil prices:
There is the further problem of speculation on the oil futures market, which in many cases has nothing to do with the actual sale, purchase, or delivery of oil. [...]
[W]e all know that some people on Wall Street are not above gaming the system. When you have enough speculators betting on the rising price of oil, that itself can cause oil prices to keep on rising. And while a few reckless speculators are counting their paper profits, most Americans are coming up on the short end -- using more and more of their hard-earned paychecks to buy gas for the truck, tractor, or family car.
Investigation is underway to root out this kind of reckless wagering, unrelated to any kind of productive commerce, because it can distort the market, drive prices beyond rational limits, and put the investments and pensions of millions of Americans at risk. Where we find such abuses, they need to be swiftly punished. And to make sure it never happens again, we must reform the laws and regulations governing the oil futures market, so that they are just as clear and effective as the rules applied to stocks, bonds, and other financial instruments. In all of these markets, reform must assure transparency, prevent abuse, and protect the public interest.
