　　Bankers and policymakers may be wringing their hands about the prospects for the world economy, but commodities traders, it seems, see no cause for concern. On Wednesday February 20th the oil price hit a new record of $101.32 a barrel. Soyabeans and platinum, among others, have also reached record prices in the past week. Vale, a Brazilian mining firm, has persuaded some steelmakers to pay as much as 71% more this year for its iron ore. Across the world the inflationary impact is tangible. In America consumer prices in January were up 4.3% on a year-over-year basis. Excluding food and energy, they were up 2.5%, well above the Federal Reserve’s comfort level.

　　Despite a few years of rising raw-materials prices, many traders remain bullish in part because of further bad news about supply. A shortage of electricity in South Africa, which has forced several big smelters to shut down, has helped cause platinum’s giddy ascent. The political upheaval in Kenya has pushed tea prices higher. A leaking pipeline in Nigeria and a row between Exxon Mobil and Hugo Chávez, the president of Venezuela, have contributed to oil’s recent gains.

　　Mining and oil firms are struggling to increase output, partly because it takes years to develop new mines or oilfields, partly because shortages of equipment and labour are hampering expansion, and partly because governments in resource-rich countries are becoming ever more prone to jacking up royalties or expropriating resources. Citigroup, for example, expects global copper production to rise by just 2% this year, even though the price is now five times higher than it was five years ago and stocks amount to less than three days’ demand.

　　Most analysts expect demand for raw materials to remain firm despite the gloomy economic news. Although Goldman Sachs, for one, expects oil consumption to fall in America, it also predicts that continued growth in booming spots such as China and India will underpin global demand. The International Energy Agency, a watchdog group for consuming countries, still expects the world’s consumption of oil to rise 1.9% this year.
