# Copper > The most-used industrial metal after steel, copper underpins every electric grid, EV, and clean-energy system, making Chile, the DRC, and Peru the indispensable suppliers to a decarbonising world. **Meta:** type: reference · date: 2026-07-03 · heads: · 4 takes · 1 lenses · 3 regions ## What it is Copper (chemical symbol Cu) is a reddish, ductile metal and the most electrically conductive base metal available at industrial scale. It moves electricity through grid cables, EV motors, solar inverters, and data-centre busbars more efficiently than any affordable substitute. End markets, per the International Copper Study Group (ICSG), split into electrical and electronic products (roughly 65% of demand), construction, industrial machinery, transport, and consumer goods. Benchmark pricing runs on the London Metal Exchange (LME) and CME Group's COMEX in New York. The dominant corporate actors are Chile's state company Codelco, Freeport-McMoRan (Grasberg, Indonesia's Papua province), CMOC Group (Tenke Fungurume Mine, Democratic Republic of Congo), Glencore, and BHP. ## History Copper has been smelted since at least 4000 BCE, underpinning the Bronze Age; industrial-scale mining in Chile's Atacama Desert accelerated through the late 19th century. Chile's Codelco was created by nationalisation in 1971 and remains the world's largest single copper-producing company. BHP's Escondida mine in Chile's Atacama began production in 1991 and is the world's largest copper mine by output. Panama's Cobre Panama mine reached full production in 2019 before Panama's Supreme Court ordered its closure in late 2023 after mass protests over a concession dispute. The United States added copper to its Critical Minerals List in 2025, reflecting both strategic stockpiling and defence-supply concerns. ## Current state As of mid-2026, global copper mine production runs at roughly 22 to 23 million tonnes per year. Chile is the top producer (roughly 5.3 million tonnes, 23% of world output), followed by the DRC (roughly 3.2 million tonnes, 14%), Peru, China, and the United States. The US produced approximately 1.0 million tonnes in 2025, valued at roughly US$11 billion. World reserves stand at approximately 980 million tonnes, with Chile holding the largest national share at about 190 million tonnes. Supply disruptions tightened the market through 2025 and into 2026. A September 2025 mud rush at Grasberg in Indonesia's Papua province forced [Freeport-McMoRan](/en/n/freeport-grasberg-mudflow-2026) to cut its 2026 copper guidance by 300 million pounds to about 3.1 billion pounds. A June 2026 work stoppage at CMOC's [Tenke Fungurume Mine](/en/n/cmoc-tfm-strike-quota-2026) in the DRC compounded a DRC government cobalt export quota restricting CMOC to about 27% of its 2025 cobalt volumes. Panama's [Cobre Panama mine](/en/n/cobre-panama-restart-2026) scored 88% on an independent audit in June 2026 but has not received government approval for a full restart; 330,000 tonnes per year remain offline since late 2023. On the supply addition side, Ivanhoe Mines' [Kamoa-Kakula smelter](/en/n/kamoa-kakula-copper-smelter-2026) in the DRC, Africa's largest copper smelter, produced 71,417 tonnes of copper anodes in Q1 2026 after commissioning in December 2025. In the United States, the threat of a Section 232 tariff on refined copper (recommended at 15% from 2027, rising to 30% from 2028) drove COMEX stocks to a record 652,000 tonnes by late June 2026 as traders front-loaded imports. The US Commerce Department's [Section 232 report](/en/n/refined-copper-232-review-deadline-2026) was due to President Trump by June 30, 2026, and the outcome will determine whether the [COMEX inventory build](/en/n/copper-comex-tariff-squeeze-2026) unwinds or persists. ## Relationships Copper is structurally tied to two macro-trends. The energy transition drives demand: each electric vehicle contains three to four times more copper than a combustion-engine car, while offshore wind turbines, solar arrays, and grid-scale storage require dense cabling. The World Bank projects copper demand rising by up to 50% under a net-zero scenario by 2040, requiring roughly US$490 billion in new mining investment. The second trend is US-China competition: China processes roughly 40% of the world's refined copper and dominates concentrate purchases from Chile, the DRC, and Peru; a US tariff on refined copper reshapes global trade flows and raises US fabrication costs. ## What to watch Two near-term decisions will shape the copper market. First, the US Administration's response to the Section 232 report will either confirm or cancel the proposed tariff, with immediate effects on COMEX stocks and the LME-COMEX price spread. Second, Panama's government must rule on a full Cobre Panama restart, which could return 330,000 tonnes per year to the global market and ease the forecast 2026 deficit. Longer term, the IEA has flagged a potential 30% supply shortfall by 2035 under net-zero demand, driven by declining ore grades and a 10-to-15-year mine development lead time, making minerals diplomacy with the DRC and Panama a durable pressure point. ## Regional takes (batched by bias / lens) ### official record - **USGS Mineral Commodity Summaries 2026, Copper** (United States, en) — Annual USGS compendium covering 2025 US copper mine output estimated at 1.0 million tonnes (valued at roughly US$11 billion), world reserves at approximately 980 million tonnes, Chile and the DRC as the leading global producers, and copper's addition to the US Critical Minerals List in 2025.
