最新报道:U.S. copper prices hit record highs as supply shortages drive premiums, with spot prices surging 15% above futures contracts. Analysts warn prolonged high costs could slow manufacturing and renewable energy projects, particularly in electric vehicles and solar infrastructure. The premium reflects tight domestic supply amid rising demand and logistical bottlenecks, with some buyers paying up to $1.50 per pound over benchmark rates. Industry groups urge policymakers to address permitting delays for new mines while recycling efforts ramp up to ease the crunch. Copper-intensive sectors face margin pressures as they struggle to pass costs to consumers.
