Ok you stupid liberals and Democrats, think about it like this. Speculators can't make any money unless they eventually sell the asset they've been holding. They also don't use up any of the oil because they are just holding it. So demand is increased and supply is decreased at the time of buying. But since speculators need to eventually sell and they don't actually use up any of the oil, they will decrease demand and increase supply at the time of selling. Add the fact that futures speculators usually don't take delivery of the physical asset, and physical supply hasn't changed either. So in the long run, what exactly has changed? The answer is nothing, unless you think the speculators are willing to hold on to the oil indefinitely for the lulz.
