What's Happening?
The copper market is experiencing a paradox where the metal's price is near all-time highs, yet smelters are struggling due to a collapse in processing fees. This situation has arisen because China has rapidly expanded its smelting capacity, outpacing
the supply of raw materials from global miners. As a result, smelters are increasingly reliant on by-products like gold, silver, and sulfuric acid for financial stability. The annual benchmark treatment and refining charges (TC/RCs) have plummeted from $80 per metric ton in 2024 to zero in 2026, with spot treatment charges turning negative. This means smelters are effectively paying miners to process copper concentrate. The shift in revenue sources has been exacerbated by China's continued increase in refined copper production, which rose by 8% in 2025, while global mine production only increased by 1%.
Why It's Important?
The current dynamics in the copper market highlight significant challenges for smelters, particularly those outside China. The collapse in processing fees threatens the viability of smelters with older infrastructure and higher fixed costs, which are more dependent on these fees. This situation poses a risk to the Western copper supply chain, as many of these vulnerable smelters are located outside China. The shift in revenue sources from processing fees to by-products like sulfuric acid and precious metals underscores the need for smelters to adapt to changing market conditions. The ongoing competition for raw materials and revenue in a structurally under-supplied market could lead to further consolidation and closures among less competitive smelters.
What's Next?
The future of the copper smelting industry may see a shift towards spot index pricing, as proposed by Chilean producer Antofagasta, to better reflect market realities. However, this proposal may face resistance from the China Smelters Purchase Team (CSPT), which has recently expanded its membership to strengthen its negotiating power. Without significant reductions in Chinese production, the gap between annual benchmark deals and spot market conditions is likely to widen. Smelters with modern technology and efficient by-product recovery systems may continue to survive, while those with outdated infrastructure may struggle to remain viable. The Western copper supply chain could face further challenges as it competes with China's dominant position in the market.
