Global Copper: Chile strike risks add to an already weakening global copper mine-supply outlook
Deutsche Bank highlights possible labour disruptions at major Chilean mines as an additional threat to copper supply amid underinvestment, operational disruptions and declining producer guidance. It identifies GLEN, Anglo, FM and FCX as preferred copper-exposed names.
Summary
Deutsche Bank highlights possible labour disruptions at major Chilean mines as an additional threat to copper supply amid underinvestment, operational disruptions and declining producer guidance. It identifies GLEN, Anglo, FM and FCX as preferred copper-exposed names.
- Strike votes were scheduled at BHP's Escondida and ANTO's Centinela mines, with government mediation required after a vote.
- Chile's copper output fell 9% year on year in July, worsening from a 7% decline in the first half.
- Deutsche Bank's guidance tracker indicates a 2% decline in 2026 output from major global copper producers.
- Global mine production fell 1% in the first seven months of 2026, while refined output rose 1.7%.
- China refined copper output fell 2% year on year in August amid weak concentrate supply and scrap tightness.
Report Interpretation
Overview
This Global Copper industry update examines how Chilean labour negotiations could further constrain mine supply at a time when global production is already weakening. Deutsche Bank links potential strikes, lower Chilean output, guidance cuts and tightening concentrate availability to a supportive copper-supply backdrop.
Core views
Deutsche Bank identifies labour disruption in Chile as a growing additional risk to copper mine supply. Unionised supervisors at BHP's Escondida mine were reportedly urged to reject the latest company offer in a 28–30 September vote, while two unions at ANTO's Centinela mine reportedly called a 26–28 September strike vote after negotiations reached an impasse. In both cases, a strike vote would lead to mandatory government mediation. The report points to Capstone Copper's five-week Mantoverde strike beginning in January, which materially reduced operating rates before a new three-year agreement was reached in February, as evidence that negotiations can affect production. Because Chilean mines commonly negotiate three-year agreements with individual unions and may have multiple unions at a mine, the scheduled renewals imply that strikes could remain a disruption factor through the rest of 2026 and into 2027. Record copper prices could increase wage and bonus demands. The labour risk comes against a broader supply backdrop that the report describes as persistently weak after years of underinvestment and disruptions at major mines. Latest company updates and high-frequency data indicate that global mine supply may decline in 2026 for the first time since 2017, following growth of less than 1% in 2025. Chilean copper output fell 9% year on year in July, compared with a 7% decline in the first half. Deutsche Bank's Global Copper Guidance Tracker forecasts a 2% decline in 2026 output for the major producers it tracks. The largest year-on-year declines are expected at BHP, Ivanhoe and FCX, while recent Chilean storms prompted ANTO and LUN to reduce guidance. The report contrasts constrained mine supply with initially stronger refined production. ICSG data show global copper mine production down 1% in the first seven months of 2026, driven mainly by declines in Chile, Indonesia and the DRC, while global refined output rose 1.7%, largely due to Chinese capacity additions and smelters maximizing scrap usage. However, the report says China is beginning to struggle with weak concentrate availability and scrap tightness: August refined output fell 2% year on year, its weakest growth rate since 2024, and output has been effectively flat month on month since April. Deutsche Bank therefore presents the supply picture as increasingly restrictive and names GLEN, Anglo, FM and FCX as its preferred copper-exposed equities, citing attractive valuations and clear catalysts.
Analysis framework
The report combines Chilean labour-agreement and strike history with mine-level events, national production data, ICSG industry statistics, Chinese refined-output trends, and a company guidance tracker. It uses these inputs to assess how disruptions and lower guidance could affect global copper supply.
Methodology notes
Copper mine and refined-supply tracking
The report compares mine production, producer guidance and disruption risks with refined-output trends to judge whether physical copper supply is tightening.
Global Copper Guidance Tracker
Deutsche Bank aggregates company production guidance to estimate the expected year-on-year change in output among major copper producers.

Impact & implications
The report argues that prospective Chilean strikes could compound an already weak mine-supply trend. It sees tightening concentrate and scrap availability as limiting China's ability to offset upstream weakness through refined-output growth, and identifies GLEN, Anglo, FM and FCX as preferred copper exposures.
Risks
- Labour disputes and potential strikes at Chilean mines could materially disrupt copper production.
- Potential US tariffs are cited as an additional risk factor affecting the copper market.
- Weak concentrate supply and scrap tightness are beginning to constrain Chinese refined production.
What to watch
- Results of strike votes and subsequent mandatory government mediation at Escondida and Centinela.
- The schedule of Chilean labour-agreement renewals through the remainder of 2026 and 2027.
- Further production-guidance changes, particularly from BHP, Ivanhoe, FCX, ANTO and LUN.
- Whether Chinese refined production remains constrained by concentrate and scrap availability.
