Copper

Why the concentration exists

Smelting and refining infrastructure is capital-intensive, energy-intensive, and geographically concentrated. A modern smelter costs $1.8-2.5 billion to build and requires sulphur-capture and acid-plant systems to meet modern standards. Building new capacity requires long lead times, access to reliable energy, and regulatory approval. Because the infrastructure is so specialized, higher throughput no longer translates cleanly into higher net copper supply in many regions.[1][9]

Lead times for new copper projects are long, running around 17 years from discovery to production. Many major projects have recently experienced significant delays and cost overruns. Full nameplate production capacity is usually achieved 2-3 years after initial ore is processed. As a result, order books fill and lead times extend, because additional throughput requires new capital expenditure rather than operational adjustments.[3][2][5]

LME Grade A copper cathodes have a purity of at least 99.99% copper and standardized dimensions of 914 x 914 x 12 mm. Copper is used as an industrial metal because of its thermal and electrical conductivity. The maximum recommended distance for copper cable in standard networks is 100 meters. These specifications make copper the dominant electrical conductor across infrastructure applications.[18][4][11]

What the evidence shows

Who supplies it

China's share of global refined copper output is approximately 50%. Refined copper production in China from January to November 2025 reached 13.3 million metric tons, a year-over-year increase of 9.8%. Aurubis produces about 1.2 million tonnes of cathodes per year in Germany, Belgium, and Bulgaria. The Aurubis cathode brands NA-ESN, HK, OLEN, and PIRDOP are registered on the LME.[23][20]

Rio Tinto increased its copper production guidance target for 2025 to 860,000-875,000 tons. VALE expects copper production to be 350,000 to 380,000 tons in 2026. The US mined about 1.06 million tonnes of copper last year, but more than half is exported as concentrate, mostly to Asia. The country's two active smelters produce just over 400,000 tonnes of refined copper.[22][9]

What it depends on, and what depends on it

SX-EW processing accounts for roughly 17% of global refined copper supply. The United States exports more than half of its mined copper as concentrate, mostly to Asia, then re-imports it as cathode or semi-finished products. This trade pattern reflects the geographic concentration of refining capacity outside major mining regions. As a result, the United States imported approximately 60% of its total refined copper needs in 2024.[23][9][24]

Copper cathode prices are linked to the London Metal Exchange daily cash and 3-month rates plus regional premiums. The typical market range in recent quarters was USD 8,000-10,000 per metric ton. In January 2026, the price of copper grade A cathode was $13,012.00 per metric ton. LME-approved copper cathodes guarantee a minimum purity of 99.99%, which distinguishes them from non-LME cathodes that may vary from 98% to 99.7% purity.[16][21][19]

Aurubis copper cathode has a CO2 footprint of 1.289 kg CO2 equivalents per tonne of copper cathode. This compares to a global average of 3.965 kg CO2 equivalents per tonne. The Deziwa project in the Democratic Republic of Congo has copper cathode capacity of 80,000 tonnes per year. China Nonferrous Mining's SMD copper cathode brand and CMOC's TFM 1 copper cathode brand have both been approved for LME listing.[20][17]

What would break it

More than half of operating copper mines globally are over 20 years old. Over the past 25 years, US output of refined copper has dropped by approximately 50%. Codelco's internal audit found that 26,875 metric tons of fine copper were recognized too early in its 2025 production figures. Chuquicamata accounted for 20,000 metric tons of the disputed volume tied to oxide material, and Ministro Hales accounted for 6,875 metric tons tied to calcium arsenite.[24][13]

Copper prices reached record highs in the first quarter of 2026 amid supply disruptions and expectations of stronger demand. Codelco's direct cash cost rose 10% to 231.8 cents per pound in the first quarter of 2026. The increase reflected currency appreciation, lower output, and higher operating expenses. Codelco's copper output dropped 8.1% to 272,000 tonnes in the first quarter of 2026 compared to the same period in 2025.[12][7][14]

What to watch

Freeport plans to restore large-scale production at Grasberg in Q2 2026. Codelco's 2026 output forecast stands at 1.33 million to 1.36 million tons. Codelco needs to boost copper output toward 1.7 million tons to meet demand from data centers and EV transition. The company's 2026 production guidance range is 1.331-1.357 million metric tons.[6][7][15]

BHP is embarking on a $10.8-billion investment program to overhaul aging operations in Chile. The aim is to produce at an average annual rate of about 1.4 million tons next decade in Chile. BHP's Copper South Australia Phase 1 and Phase 2 growth projects are expected to lift BHP's copper output capacity by 790,000 to 910,000 tonnes over the period from 2029 to 2038. VALE's Bacaba copper mine project, with an average annual copper production of 50,000 tons, is expected to be commissioned in the first half of 2028.[8][10][22]

China has planned refining capacity additions of 2.5 million tonnes between 2025 and 2028. Approximately 2 million tonnes of suspended Chinese smelting capacity exist under the current policy cycle. China's top copper smelters announced output cuts to combat negative processing fees in November 2025. Antofagasta agreed zero copper processing charges for 2026 with a Chinese smelter.[23][6]
