Copper Treatment Charges Collapse: A Structural Shift in Global Supply
Copper treatment charges have remained negative for nearly two years, signaling a structural reconfiguration in the copper value chain. This shift is driven by a capacity mismatch between Chinese smelters and global mine supply growth.
The traditional processing relationship, where miners pay smelters to process concentrate into usable metal, has inverted due to the collapse of treatment charges (TCs) and refining charges (RCs). The current record-low TCs have been fueled by China's aggressive expansion of smelting infrastructure, which outpaced mine supply growth.
A key factor contributing to this capacity mismatch is Chile's copper supply disruption. Major operators, such as Antofagasta and Codelco, have experienced production setbacks due to extreme rainfall events, power outages, and ongoing repairs to pipeline platforms and water management infrastructure.
