Copper supply tightness deepens
Industry analysts warn copper tightness reflects not just resource scarcity but a shortage of projects that are financeable and executable, and inventories are drawing down faster than the industry can replace them. Reports cite projections such as an ING estimate of a 600,000‑tonne refined deficit in 2026 and argue the problem is structural, not temporary ( ).
Copper is getting tighter because the world is not bringing on enough new supply fast enough to replace what it is using. (think.ing.com) ING said on December 8, 2025 that its 2026 refined copper balance had swung to a deficit of about 600,000 tonnes, after an estimated deficit of about 200,000 tonnes in 2025. The bank tied that shift to mine disruptions, tight concentrate supply and low exchange inventories outside the United States. (think.ing.com) The recent supply hits are concentrated at some of the world’s biggest mines. ING said Freeport’s Grasberg mine in Indonesia, which contributes about 4% of global copper output, is recovering only gradually, while Kamoa-Kakula in the Democratic Republic of the Congo and El Teniente in Chile also suffered disruptions in 2025. (think.ing.com) Copper moves through a long chain: mines produce ore, smelters turn concentrate into metal, and fabricators turn that metal into wire, motors and pipes. Plusmining said on April 13 that the bottleneck now is not only geology but development, with permitting and construction timelines stretching so far that the average lead time from discovery to production is about 17 years. (mining.com) That timeline is colliding with stronger long-run demand assumptions. Plusmining said base-case copper price assumptions used in more than 300 mining studies rose from about $3.00 a pound in 2015-2020 to roughly $4.80 a pound in early 2026, a jump of about 60%. (mining.com) The demand side is not limited to one industry. The International Energy Agency said in its 2025 critical minerals outlook that demand for key energy minerals continues to rise across all scenarios, driven by the rapid deployment of energy technologies, and its copper outlook says grids are the largest source of copper demand from clean energy. (iea.org; iea.org) The supply picture also looks tighter in official industry forecasts, though less severe than ING’s. The International Copper Study Group’s press releases page shows it issued a March 26, 2026 monthly release, and market summaries circulated from that forecast put the group at a 150,000-tonne refined deficit for 2026. (icsg.org; theoregongroup.com) Banks and consultants do not agree on the exact size of the gap, but they are moving in the same direction. J.P. Morgan has projected a roughly 330,000-tonne refined deficit in 2026, between the International Copper Study Group’s estimate and ING’s more bearish call. (jpmorgan.com) Trade policy has added another distortion. ING said traders pulled large volumes of copper into the United States to get ahead of possible tariffs, lifting U.S. refined imports by more than 50% year to date through August 2025 and leaving inventories outside the U.S. with less cushion against new disruptions. (think.ing.com) Mining Journal summed up the issue on April 16 as an “executability gap”: the industry has resources in the ground, but fewer projects that can clear financing, permits, engineering and construction on time. Until that changes, tighter inventories and repeated supply shocks are likely to keep copper markets under pressure. (mining-journal.com)
