Copper prices have been volatile throughout 2025 and into 2026, fueled by economic uncertainty from an ever-changing US trade policy and strong supply and demand fundamentals.

The International Copper Study Group , the leading copper market watcher, reported an apparent refined copper surplus of 206,000 tonnes through the first 11 months of 2025, above its full year 2025 prediction of a 178,000 tonne surplus. For 2026, the group predicts a deficit of 150,000 tonnes.

Demand from the energy transition and increased wealth and urbanization in the global South are expected to stress supply chains over the coming years, with the International Energy Agency anticipating a 30 percent shortfall in copper supply by 2035.
