Griftopia: Bubble Machines, Vampire Squids, and the Long Con That Is Breaking America

With the speculator, however, everything runs smoothly. The corn grower goes to the market with his corn, maybe there are no cereal companies buying, but the speculator takes his crop at $2.80 a bushel. Ten weeks later, the cereal guy needs corn, but no growers are there—so he buys from the speculator, at $3.00 a bushel. The speculator makes money, the grower unloads his crop, the cereal company gets its commodities at a decent price, everyone’s happy. This system functioned more or less perfectly for about fifty years. It was tightly regulated by the government, which recognized that the influence of speculators had to be watched carefully. If speculators were allowed to buy up the whole corn crop, or even a big percentage of it, for instance, they could easily manipulate the price. So the government set up position limits, which guaranteed that at any given moment, the trading on the commodities markets would be dominated by the physical hedgers, with the speculators playing a purely functional role in the margins to keep things running smoothly.
