Few economic forces are more important than commodity prices. When they rise they transfer riches and power from consumers to producers; when they fall, it is as near as anything in economics to a free lunch for consumers. With so much at stake, turning points are important for the global economy. Such a moment appears to be at hand.
Across a wide range of commodities, prices are falling and sometimes falling fast. The Bloomberg commodity index – which acts as a benchmark for commodity investments – fell to its lowest level in five years this week. Prices are being pushed down by the increasing supply of most commodities and a weakening global economy, including a slowing China, the world’s largest consumer for many of these raw materials. Whether it is oil, corn, iron ore, coal, cotton or copper, prices are falling quickly.
The International Monetary Fund estimates that global commodity prices are 8.3 per cent lower than at the start of the year. In its recent World Economic Outlook report, the IMF demonstrated how a $20-a-barrel oil price decline would increase the real income of consumers, boosting domestic demand and growth in consuming countries and hitting exports and demand in producer nations. The fund estimated the net effect would increase world gross domestic product 0.5 per cent alone, and if economic confidence were improved as a result, that figure could rise to about 1.2 per cent. Gavyn Davies, chairman of Fulcrum Asset Management, says the figures were plausible and by any measure “quite big”.
