Copper futures settled lower on Wednesday due to US-Iran tensions. However, some gains were limited as a tame reading of US inflation eased the threat of higher interest rates and a physical shortage in London pushed the premium on immediate delivery to its widest of the year. Traders remained cautious about potential US import tariffs on copper that continued to divert metal away from international markets and into US warehouses.
Copper futures for September delivery fell $0.0185 to settle at $6.6155 a pound on the Comex metals division of New York Mercantile Exchange. Copper on the London Metal Exchange was down by 0.17% at $14,132 a ton.
