Copper Inventory Rises 7,300 mt WoW, Down 12,800 mt YoY as Regional Trends Diverge

Copper prices advanced towards a record closing high as tightening physical supply continued to support the market alongside resilient long-term demand. The London Metal Exchange (LME) three-month copper contract strengthened as sustained inflows of metal into the United States and increased buying activity from China reduced the availability of copper in other regions. Large volumes of refined copper have been shipped into the U.S. this year as traders positioned ahead of a potential decision on refined copper import tariffs. At the same time, stronger purchasing activity from China has intensified competition for available material, further tightening the physical market. These developments have contributed to copper gaining approximately 14% since the beginning of 2026, building on three consecutive years of annual gains. Beyond near-term supply tightness, the market continues to be supported by long-term demand from power infrastructure, renewable energy, electric vehicles and artificial intelligence-related data centres. However, declining ore grades at existing operations and the increasing cost and complexity of developing new mines continue to constrain future supply growth. The latest price gains highlight a market increasingly influenced by physical supply constraints rather than demand alone. With inventories remaining tight and new mine supply struggling to keep pace with long-term consumption growth, sustained price strength could continue to support investment in mine expansions, brownfield redevelopment and domestic copper processing capacity.

[Deep Seismic Risks Emerge, Codelco Suspends Andes Norte Expansion Project at El Teniente Copper Mine] Codelco temporarily suspended development and construction activities at the Andes Norte project of the El Teniente copper mine due to potential new-type seismic risks emerging in deep areas, while other production areas of the mine remain in operation. The company will further strengthen seismic monitoring and technical assessment and has not yet announced a resumption time. Andes Norte is an important project for the deep resource succession of El Teniente. This suspension may increase uncertainty over the mine’s medium and long-term production recovery and the commissioning of deep projects.
