Copper futures settled down on Tuesday as a stronger dollar makes copper more expensive for buyers using other currencies. Copper prices weakened further on subdued demand after incoming US President-elect Donald Trump's latest tariff proposal for some of the country's biggest trading partners sparked risk-off moves across global markets.
Copper futures for March delivery lost 0.73% to settle at $4.1288 a pound on the Comex metals division of New York Mercantile Exchange. Copper on the London Metal Exchange was down by 0.50 percent at $9,000.50 a ton.
