Copper futures settled higher on Wednesday as the US dollar weakened against its major peers ahead of the key US Q1 GDP data. However, mounting concerns over global economic growth and demand limited further gains.
Copper futures for May delivery gained $0.0055 to settle at $3.8535 a pound on the Comex metals division of New York Mercantile Exchange. Copper on the London Metal Exchange was up by 0.29 percent at $8,552.50 a ton.
