Food PRICE RISE

ONE of the odder features of last weekend's vote in Venezuela was that staple foods were in short supply. Something similar happened in Russia before its parliamentary election. Governments in both oil-rich countries had imposed controls on food prices, with the usual consequences. Such controls have been surprisingly widespread—a knee-jerk response to one of the most remarkable changes that food markets, indeed any markets, have seen for years: the end of cheap food.
In early September the world price of wheat rose to over $400 a tonne, the highest ever recorded. In May it had been around $200. Though in real terms its price is far below the heights it scaled in 1974, it is still twice the average of the past 25 years. Earlier this year the price of maize (corn) exceeded $175 a tonne, again a world record. It has fallen from its peak, as has that of wheat, but at $150 a tonne is still 50% above the average for 2006.
