Copper price holds above $14,400: supply–demand risks mapped for mine planners
Reviewed by Tom Sullivan

First reported on MINING.com
30 Second Briefing
Copper held at $14,446/t on the LME on Tuesday, near this month’s $14,875 record, as workers in two unions at Antofagasta’s Centinela mine in Chile rejected a final contract offer and triggered a mediation period ahead of a possible strike. Wage talks at BHP’s Escondida, the world’s largest copper mine, have also been delayed after a fatal accident, compounding supply concerns. ICSG data show mine output running at an annualised 23 Mt in July versus refined demand of 29 Mt and supply of 28.4 Mt, with Deutsche Bank projecting prices could reach $22,000/t by Q2 2027.
Technical Brief
- Two unions at Antofagasta’s Centinela mine have formally rejected a final collective contract offer.
- The strike vote at Centinela initiates a mandatory mediation period before any legal walkout can start.
- Wage negotiations at BHP’s Escondida have been postponed specifically due to a recent fatal onsite accident.
- Large refined copper inventories are accumulating in US warehouses as traders pre-empt potential import tariffs.
- China’s Yangshan copper import premium is trading near its highest level since 2022, signalling strong seaborne demand.
- ICSG reports July mine output at an annualised 23 Mt, 4% lower than June’s annualised rate.
- Refined copper demand reached an annualised 29 Mt, with refined supply at 28.4 Mt, implying a 0.6 Mt annualised deficit.
- Deutsche Bank’s $22,000/t copper price projection by Q2 2027 assumes intensified competition for constrained physical supply.
Our Take
In our database, Antofagasta and BHP feature repeatedly in 2026 copper-price coverage, with earlier pieces (e.g. the August 19 and September 1 items) already flagging a structural squeeze, so strike risk at Chilean assets like Escondida and Centinela likely amplifies an existing supply‑side tightness rather than creating it.
Chile‑linked producers such as Antofagasta, Codelco and BHP recur across several recent copper items in our coverage, suggesting that operational or labour shocks in Chile now carry disproportionate signalling power for global copper and critical minerals markets relative to other Latin American jurisdictions.
