As of November 21, the SMM Imported Copper Concentrate Index (TC) stood at -$42.32/dmt, marking a full year of 2025 with spot TC levels persistently in negative territory, the weakest in historical record. The market widely expects that 2026 long-term contract TC will likely remain negative. From a supply-side perspective, global greenfield project additions are extremely limited. At the same time, existing mines have faced frequent operational disruptions, with some producers failing to meet output targets. The incremental ramp-up of smelters in Indonesia and Africa has also temporarily diverted copper concentrate flows. Against this backdrop, the supply-demand imbalance in copper concentrate is deepening.
In response to the persistently worsening TC, smelters worldwide are actively adjusting. Since the start of Q4 2025, global smelters have shown significantly more aggressive bidding activity compared with previous years. Notable examples include SPCC, Anglo, and LS, which have launched tenders for 2025–2026 delivery slots in order to lock in 2026 processing margins early, ease financial statement pressure, and gain leverage ahead of long-term contract negotiations. Some companies have also significantly raised prepayment ratios to ensure stable feedstock supply and mitigate liquidity risks.
On the Chinese side, domestic smelters are also actively adjusting their export structure to counteract rising costs and negative TC pressure. In recent weeks, several major Chinese smelters have initiated preliminary negotiations for 2026 USD-denominated cathode export long-term contracts, relying on stable downstream demand to support export order locking under processing trade frameworks. Thanks to robust demand for copper rod and tube products, Chinese smelters have notably expanded their market share in Southeast Asia and the Middle East. According to SMM research, China’s copper cathode exports in 2025 are expected to reach approximately 700,000 tons, an increase of around 200,000 tons YoY. This strategy has helped hedge against the pricing loss caused by negative imported TC while expanding smelters' market influence across the Asia-Pacific region.
Looking ahead to 2026, the tight balance in the copper concentrate market is expected to persist.
Constrained by project commissioning schedules and ongoing mine operation uncertainties, global supply elasticity remains limited, while refined copper smelting capacity expansion is still mainly concentrated in China, Africa, and Indonesia. Based on the current market structure, COMEX-LME arbitrage pricing mechanisms have already been reflected in some long-term contract offers by smelters. In 2026, regional supply-demand mismatches are likely to create key arbitrage opportunities, making this one of the most important themes in the spot copper concentrate trade.
