Speculators set up a casino where the chips were the stomachs of millions. What does it say about our system that we can so casually inflict so much pain?
It starts with an apparent mystery. At the end of 2006, food prices across the world started to rise, suddenly and stratospherically. Within a year, the price of wheat had shot up by 80 per cent, maize by 90 per cent, rice by 320 per cent. In a global jolt of hunger, 200 million people – mostly children – couldn't afford to get food any more, and sank into malnutrition or starvation. There were riots in more than 30 countries, and at least one government was violently overthrown. Then, in spring 2008, prices just as mysteriously fell back to their previous level. Jean Ziegler, the UN Special Rapporteur on the Right to Food, calls it "a silent mass murder", entirely due to "man-made actions."
Most of the explanations we were given at the time have turned out to be false. It didn't happen because supply fell: the International Grain Council says global production of wheat actually increased during that period, for example. It isn't because demand grew either: as Professor Jayati Ghosh of the Centre for Economic Studies in New Delhi has shown, demand actually fell by 3 per cent. Other factors – like the rise of biofuels, and the spike in the oil price – made a contribution, but they aren't enough on their own to explain such a violent shift.
For over a century, farmers in wealthy countries have been able to engage in a process where they protect themselves against risk. Farmer Giles can agree in January to sell his crop to a trader in August at a fixed price. If he has a great summer, he'll lose some cash, but if there's a lousy summer or the global price collapses, he'll do well from the deal. When this process was tightly regulated and only companies with a direct interest in the field could get involved, it worked.
Then, through the 1990s, Goldman Sachs and others lobbied hard and the regulations were abolished. Suddenly, these contracts were turned into "derivatives" that could be bought and sold among traders who had nothing to do with agriculture. A market in "food speculation" was born.
