Copper concentrate supply remains constrained as Freeport-McMoRan's Grasberg mine in Indonesia, one of the world's largest copper operations, continues its ramp-up at a slower pace than market expectations. The delays compound an already tight concentrate market.
Jefferies analysts estimate an average annual supply deficit of 491,000 tonnes from 2025 through 2030, driven by depletion at existing mines, declining ore grades, and a thin project pipeline. New mine developments face 10-15 year lead times, limiting near-term relief.
On the demand side, global refined copper consumption continues to grow at 2.5-3% annually, led by electrification, AI data center infrastructure, and renewable energy deployment. Electric vehicles require roughly 80kg of copper per unit, triple that of an ICE vehicle.
The potential 25% US tariff on refined copper imports, expected by June 2026, is already reshaping trade patterns. Importers are accelerating pre-tariff stock-building, with copper flows redirected toward US warehouses. This has tightened availability in Europe and Asia.
LME copper inventories stand at 364,100 tonnes, down 0.87% week-on-week. While absolute levels are not critically low, the trend is declining amid steady drawdowns across Asian and European warehouses.
Supply risk is skewed to the upside through H2 2026. Consider indexing new contracts to LME + a negotiated premium rather than fixed price, as the direction of tariff policy and Grasberg recovery will determine whether prices break $14,000/mt.
