Copper futures settled higher on Wednesday due to firm demand with optimism over raising the US debt ceiling limit. However, looming fears of a US recession and a rebound in the US dollar index limited further gains in copper prices.
Copper futures for July delivery gained $0.0875 to settle at $3.7545 a pound on the Comex metals division of New York Mercantile Exchange. Copper on the London Metal Exchange was up by 2.22 percent at $8,302 a ton.
