Copper Drops on Concern Economic Growth to Slow in China, U.S.

Copper fell the most in three weeks on concern that economic growth will slow in China and the U.S., the world’s biggest metal users.

The pace of recovery in the U.S. is likely to be “more modest” than forecast, the Federal Reserve said yesterday. In July, industrial output in China had the smallest gain in 11 months, and retail sales, new lending, producer prices and money supply increased more slowly, reports showed. Copper also dropped as the dollar’s surge eroded the appeal of commodities.
