Copper prices reach record highs driven by AI demand, supply constraints, and U.S. tariff uncertainty
Copper futures on both the LME and Comex reached all-time highs in September 2026, with LME benchmark copper hitting approximately $14,510 per tonne. The rally was driven by tightening mine supply, strong demand from AI data center infrastructure and EV manufacturing, and anticipation of potential U.S. tariffs on refined copper imports. American buyers stockpiled copper ahead of possible tariff announcements, draining inventories from LME and Shanghai warehouses while Comex stockpiles surged.
