Copper futures gained on Monday as the US dollar retreated slightly from its 20-year high. However, some gains were capped after the US Fed officials said they might raise interest rates by another 75 basis points later this month to tackle high inflation.
Copper futures for September delivery gained $0.0335 or 1.04% at $3.2450 a pound on the Comex metals division of New York Mercantile Exchange.
