Copper

The electrical workhorse of civilization — and the market’s favorite economic barometer.

Copper conducts electricity better than any metal except silver, at a fraction of the cost — which makes it the default material for wires, motor windings, transformers, and busbars. "Doctor Copper" earned its nickname because demand tracks global industrial activity so closely that its price is read as an economic diagnosis. Electrification has now added a structural layer on top of that cyclical base: battery-electric vehicles typically require more copper than combustion vehicles, while charging infrastructure, renewables, data centers, and grid upgrades add demand alongside construction and industry. ICA-commissioned research published in 2017 used 83 kg as a battery-electric vehicle benchmark; copper content varies by design, and that figure is not a current fleet average.

Market Dynamics

Copper trades on deep, liquid exchanges — LME, COMEX, and Shanghai — making it a reference market for the mining sector. The core tension is between demand growth and lumpy, slow-arriving supply. The IEA’s 2021 analysis of major mines that entered production in 2010–2019 found an average of more than 16 years from discovery to first production across its sample of minerals; that is evidence of development lead times, not a timetable for every copper project. Declining grades, water constraints and permitting can add pressure. Disruptions such as Cobre Panamá’s suspension — listed on care and maintenance in ICSG’s 2025 factbook — remove capacity, while scrap flows provide another source of metal when prices rise.

Supply Chain

Mined supply concentrates in the Andes — Chile and Peru together supplied about 35% of the world total in USGS’s 2025 estimates — while the DRC ranked second globally, ahead of Peru. China dominates the midstream: USGS estimates 14 million tonnes of refinery output out of a rounded world total of 29 million tonnes in 2025, or about 48%. Refining output and mine output are different measures. Downstream, fabricators turn cathode into wire rod, tube, and sheet close to end markets. Recycling adds both secondary refined metal and scrap used directly by fabricators; those routes must be distinguished before assigning a recycling share.

Outlook

The IEA’s Global Critical Minerals Outlook 2025 projects copper demand growing about 30% to 2040 in its Stated Policies Scenario. Its announced mine-project pipeline implies a potential 30% mined-supply shortfall in 2035 against that scenario’s requirements. These are conditional projections, not a guaranteed shortage: new projects, recycling, substitution and changes in demand can alter the balance. The debate is about the timing and scale of the gap, including how much aluminum substitution and material efficiency can absorb. Copper provides broad exposure to electrification, but prices also respond to industrial cycles, inventories, trade policy and project execution.

Evidence snapshot

Where copper is mined — and where it is refined

These are USGS estimates for 2025, published in its 2026 copper chapter. Compare the two production columns separately: mine output measures copper recovered from mining; refinery output measures refined metal, including primary and secondary production. They are stages in the supply chain, not quantities to add together.

Why mining, refining and scrap tell different stories

A processing hub is not necessarily a mining hub

Chile supplied about 23% of mined copper in these 2025 estimates, but China produced about 48% of refined copper while mining only about 8% of the world total. Concentrate trade and processing capacity connect these different geographies. A mine disruption and a refinery disruption therefore affect different stages.

More smelters do not create more concentrate

Treatment and refining charges are fees for processing concentrate, not the copper metal price. When processing capacity expands faster than mine feed, competition for concentrate can squeeze these fees even while metal prices rise. In a commentary dated , the IEA described exactly this pressure. It is a dated example, not a claim about today’s prices.

A recycling percentage needs a definition

ICSG reports that scrap-derived secondary copper represented 17% of world refined production in 2024. This excludes scrap remelted directly into products without passing through a refinery. It is therefore not the share of all copper use supplied by recycling. Scrap availability, quality and collection also limit how quickly recycling can respond to demand.
