Copper prices surge amid supply shortages and U.S. tariff concerns

Global copper prices have surged, reaching record levels on the London Metal Exchange (LME) due to a combination of supply constraints and market speculation. A significant driver of recent price volatility is the anticipation of proposed U.S. tariffs on refined copper imports, potentially beginning in 2027. This has led to increased stockpiling within the United States, with Comex-approved inventories accounting for approximately 70% of globally traceable stocks, thereby tightening availability for other international markets.

Supply-side pressures are further exacerbated by shortages in copper concentrate. Mining companies like Antofagasta have faced challenges, including negative treatment charges for concentrate sales. Meanwhile, demand remains robust across sectors such as renewable energy, electric vehicles, and artificial intelligence infrastructure. In India, the price surge and a weak rupee are threatening to increase import bills and rising working capital costs for manufacturers, as domestic production only meets about half of the country's refined copper demand.

In China, while economic growth exceeded expectations in the third quarter, fixed capital investment saw a decline. Low inventories in China have contributed to rising premiums, even as global market dynamics remain influenced by shifting demand in the technology and defense sectors.
