Copper prices climbed to a fresh record on the London Metal Exchange as distortions to trade flows due to concerns over potential U.S. tariffs collided with supply challenges at key mines worldwide.

The surge reflects growing anxiety among traders and investors about the impact of proposed tariff policies on global commodity markets. Market participants are closely watching developments out of Washington, with many fearing that new trade barriers could disrupt established supply chains.

At the same time, operational issues at several major mining operations have tightened available supply. Analysts note that the combination of geopolitical uncertainty and physical bottlenecks has created a perfect storm for price appreciation.

LME copper futures reached $9,500 per metric ton, marking the highest level since records began. The rally has drawn attention from hedge funds and commodity trading houses, including Glencore and Codelco, which are adjusting strategies amid the volatile environment.

Market watchers expect continued turbulence as U.S. tariff decisions loom and mining companies assess their production outlook for the remainder of the year.
