Copper futures settled down on Wednesday as China's October factory gate inflation hit a 26-year high, which could renew pressure on policymakers of the world's top consumer of copper to lift interest rates. Firm US dollar against its major peers too weakened the appeal of dollar-denominated metals.
Copper futures for December delivery fell $0.05 to settle at $4.3230 a pound on the Comex metals division of New York Mercantile Exchange. Copper on the London Metal Exchange was down 0.21 percent at $9,533 a ton.
