The global copper market is undergoing significant upheaval driven by supply-demand imbalances, China’s evolving role, and U.S. trade policy uncertainty. At this week’s Asia Copper Week in Shanghai, pricing negotiations were unusually intense—miners pressured smelters for record-low processing fees, while annual premiums for refined copper shipped to China hit an all-time high. Mercuria Energy Group’s head of metals research Nicholas Snowdon stated, “This is a historic point of tightness for the copper supply chain”, framing the moment as pivotal for copper bulls.

This led to tough negotiations, with risks of abandoning the global benchmark system (centered on China’s smelters and major miners), complicating supply planning. Aurubis’ Tim Kurth urged long-term focus: the benchmark ...
