In the context of the continuous expansion of copper consumption driven by the energy transition, the supply constraints at the copper mining end are becoming the core contradiction influencing the direction of the copper market.
From the demand side, the construction of photovoltaic and wind power projects, energy storage facilities, new energy vehicles, and grid upgrades all lead to a rigid consumption of copper resources. The demand growth brought by emerging industries is long-term and certain, which has also made the market pay special attention to the output release capacity of the copper mining end. However, the actual supply situation has sent out a signal of tightness. According to statistics from the International Copper Study Group (ICSG), in the first half of 2026, global copper mine production declined by 1.1% year-on-year. The production pressure of industry leaders is prominent, and the copper mine production of major companies such as the Chilean National Copper Company and Freeport-McMoRan has experienced double-digit declines.
The underperformance of major mining companies' output was not an isolated incident; it has become a common problem across the industry. Several multinational mining companies have successively lowered their production targets for 2026, and the actual output from mines has often fallen short of market expectations. The reasons for this situation come from multiple aspects: in core copper-producing regions such as South America and Indonesia, the ore grades of old mines have been continuously declining, maintenance and repair of equipment have increased, the ramp-up progress of new projects has fallen short of expectations, and new production capacity cannot fill the gap caused by the reduction in output from old mines; in addition, the mining industry has suffered from insufficient capital investment for many years, and the exploration, approval, and production cycles of large copper mines are lengthy, making it difficult to release sufficient growth in a short period. Overall, the supply elasticity of global copper mines is relatively weak.
The changes in production data have also prompted institutions to revise their previous market judgments. Overseas institutions originally expected an increase in copper mine supply this year. For example, Morgan Stanley's latest assessment has significantly adjusted its expectations, believing that the annual copper mine production may remain flat or even decline slightly. Based on the current production trend, it is expected that in 2026, there will be the first annual decline in global copper mine production since 2017, and the bottleneck of copper mine capacity growth becomes increasingly clear.
The expectation of supply contraction has been transmitted to the trading market. International copper prices have remained strong throughout the year, and market funds have begun to price in the long-term premium brought about by copper mine shortages. On one hand, supply growth has encountered significant obstacles; on the other hand, demand in emerging sectors is still steadily expanding. The risk of a long-term imbalance in the future supply and demand in the copper market has thus risen.
The final trend of the copper mine output for the entire year mainly depends on three major variables: the recovery levels of production capacity of each mine in the second half of the year, the uncertainties brought by the weather in the South American production areas, and the effectiveness of the production plans of major mining enterprises. In the long term, the tight supply of copper mines will provide a solid fundamental support for the copper price.
