Copper Concentrate TC/RC at Zero: Smelter Economics and the 2026 Benchmark Reset
Analyzes the collapse of treatment and refining charges to zero and negative spot levels, the 2026 annual benchmark between miners and Chinese smelters, and the byproduct credit economics keeping non-Chinese smelters solvent.

Summary
Treatment and refining charges have collapsed to zero and below, an unmistakable signal that smelting capacity has outrun mine supply. This report explains the mechanics, from the annual benchmark negotiation to negative spot charges, and examines how Chinese smelter overcapacity, byproduct acid and precious-metal credits, and contract terms determine which smelters survive. It identifies the capacity most exposed to rationalization.
