Copper futures ended lower on Wednesday due to concerns over demand following fading optimism about the progress of a Covid-19 vaccine. A higher dollar makes dollar-denominated commodities more expensive for holders of other currencies.
Copper futures for December delivery fell $0.0215 to settle at $3.1340 a pound on the Comex metals division of New York Mercantile Exchange. Copper on the London Metal Exchange was down 0.68% at $6,885 a ton.
