Copper: Price Rebound and Performance Overview
Copper is one of the key raw materials for electrification, grid expansion, and digitalization. In 2025, the market has increasingly decoupled from oil and iron ore, following its own fundamentals more closely. Performance data as of September 30, 2025, highlights: Copper is up +18.18% year-to-date, while broad commodity baskets perform significantly weaker. Compared to US equities (S&P 500 Total Return), the copper mining sector has also shown robust relative development over the past three to five years. The price increase reflects, on the one hand, intact demand impulses from energy and technology markets, and on the other hand, the market’s increasing sensitivity to new supply-side disruptions.
Supply-Side Shocks Exacerbate Copper Deficit
A central driver of the recent copper price surge is production outages at some of the largest mines. These shutdowns and restrictions span from Indonesia to Chile and the Democratic Republic of Congo. Particularly significant is the disruption at Freeport-McMoRan’s Grasberg operation, the world’s second-largest copper mine: Approximately 591,000 tonnes of production could be lost by December 2026. Additionally, there is reduced output at the Kamoa-Kakula conglomerate (estimated ~300,000 tonnes less after flood events), a lowered annual forecast for Teck Resources (–~60,000 tonnes), and lower volumes at Codelco’s El Teniente (–33,000 tonnes). The ongoing shutdown of Cobre Panamá (First Quantum) since late 2023 further removes more than 300,000 tonnes from the market.
This chain of disruptions exacerbates an already strained foundation: 2025 is shaping up to have the weakest mine growth rate since 2011. Secondary raw materials can only partially close the gap – high-quality copper scrap is scarce, and lower grades require additional refining capacities. Accordingly, major investment banks are raising their copper price targets, citing the increased risk of further supply interruptions. For the market, this means: Any additional incident can trigger noticeable price reactions.
US Industrial Policy Supports Copper Producers and Junior Companies
Politics also acts as a catalyst. In the US, the federal government directly invested in Trilogy Metals (10% stake plus warrants) and, by decree, enabled the construction of the Ambler Access Road in Alaska – an infrastructure project for the development of critical minerals. Comparable measures affected other critical raw materials: At Lithium Americas (Thacker Pass), an equity/financing package was re-established as part of DOE (Department of Energy) funding; at MP Materials, the Department of Defense secured influence and long-term off-take agreements for magnetic materials through preferred equity tranche financing. For the copper sector – especially for US-focused junior producers – such interventions mean faster approval processes, greater planning certainty along the supply chain, and visible political interest in domestic supply.
At the same time, macroeconomic factors influence the picture: A 25 basis point interest rate cut by the US Federal Reserve and debates over tariffs and budgetary issues directed capital flows into tangible assets and “critical minerals”. Copper benefits in this environment as a basic material for grids, electromobility, storage, and defense technologies.
Consolidation in the Copper Sector: Multi-Billion Dollar Bets on Supply and Security Issues
The strategic realignment of major mining companies is evident in a new M&A wave centered on copper. The announced Anglo-Teck merger (valued at $53 billion) would create one of the largest pure-play copper entities and underscores the shift away from coal in favor of long-term, politically supported demand areas. In recent years, other transactions made headlines: Lundin acquired Filo Mining (approximately $3.0 billion for the free float), BHP bought Oz Minerals (AUD 9.6 billion), and Rio Tinto acquired the remaining stake in Turquoise Hill ($3.3 billion). Concurrently, companies like Teck streamlined their portfolios through coal spin-offs, while Anglo American, after fending off a takeover attempt by BHP, separated or divested assets in platinum, coal, and nickel – with a clear focus on copper.
The common thread: Copper combines market size, liquidity, and strategic relevance in a way that makes it a preferred target for investments and consolidations. At the same time, structural challenges persist: low inventories, underinvested project pipelines, and ongoing operational risks. In summary, these factors shape the sector at the start of Q4 2025 – with high attention to supply announcements, approval progress, and further portfolio decisions by the majors. Sooner or later, in our view, well-positioned copper explorers are also likely to come into market focus, as ultimately these are the companies that can ensure supply in the project pipeline.
