Copper futures settled higher on Friday as the American currency weakened against its major peers overseas after US President Donald Trump threatened to impose a new 50% tariffs on European Union imports from June 1 and a 25% tariff on Apple iPhones made outside the United States. However, worries over the United States' worsening fiscal health, limited further gains in copper prices.
Copper futures for July delivery gained $0.157 to settle at $4.8365 a pound on the Comex metals division of New York Mercantile Exchange. Copper on the London Metal Exchange was up by 1.15 percent at $9,610 a ton.
