US Copper 'Mountain' Masks Underlying Risk
A surge of late-2025 imports has created a growing “copper mountain” in the U.S., temporarily easing supply constraints. But analysts warn this inventory surplus masks underlying risks, as robust demand for the metal in EVs and construction could quickly reverse the situation if global supply is disrupted.
The surge in copper inventory was driven by fears of new trade policies, leading U.S. refined copper imports to jump 81% in 2025 to a record 1.63 million metric tons. This front-loading, in anticipation of a potential 15% tariff on refined copper, resulted in a surplus of over 700,000 metric tons beyond domestic demand. This domestic surplus contrasts sharply with a tightening global market hobbled by significant supply disruptions. In 2025, operations were impacted by a mudslide at the Grasberg mine in Indonesia, a tunnel collapse at Chile's El Teniente mine, and flooding at the Kamoa-Kakula mine in the DRC, constraining the global supply chain. Meanwhile, demand is accelerating, driven by the green transition and artificial intelligence. A typical battery-electric vehicle requires about 183 pounds of copper, nearly four times that of a conventional car. Concurrently, the build-out of AI data centers could demand an additional 1 million metric tons of copper in the U.S. by 2030. The domestic supply chain faces its own regulatory pressures. In May 2024, the EPA finalized new emission standards for the nation's two remaining primary copper smelters. However, citing national security and the risk of further closures, the White House granted the industry a two-year relief from this rule in October 2025. For publicly traded manufacturers, the SEC's climate disclosure rules, adopted in March 2024, will require reporting on material climate-related risks and, for larger firms, Scope 1 and 2 greenhouse gas emissions. While the rules are currently stayed pending judicial review, they signal a broader push for transparency in supply chain and operational climate impacts. This combination of dislocated inventory, strained global production, and robust demand creates significant price volatility. J.P. Morgan forecasts copper prices could reach $12,500 per metric ton in the second quarter of 20
