Copper Supply Glut Seen Tripling as Prices Sink 10%: Commodities

The worldwide glut of copper supply is poised to almost triple in 2014, driving prices to the lowest in at least three years at a time when the International Monetary Fund says economic growth will be weaker than forecast.

The surplus will reach a 13-year high of 272,000 metric tons, according to data from Barclays Plc and the International Copper Study Group in Lisbon. Codelco and Freeport-McMoRan Copper & Gold Inc., the biggest producers, are among those scheduled to add supply next year. The metal will drop as low as $6,450 a ton in 2014, or 10 percent less than last week’s close, the median of 22 analyst estimates compiled by Bloomberg shows.
