Copper futures ended marginally lower on Tuesday due to concerns over the delivery of US President Joe Biden's $1.9 trillion pandemic relief package. Meanwhile, global investors are awaiting the US Federal Reserve's monetary policy decision. However, weakness in US dollar makes metals cheaper for holders of other currencies and capped losses in copper prices.
Copper futures for March delivery lost $0.01 to settle at $3.6195 a pound on the Comex metals division of New York Mercantile Exchange. Copper on the London Metal Exchange was up 0.5% at $8,008.50 a ton.
