Copper prices are flirting with historic highs as global inventories plummet and geopolitical tensions create a perfect storm for the red metal. Recent data from the London Metal Exchange shows a dramatic drawdown in warehouse stocks, which crashed to around 107,050 metric tons by late August from over 166,000 just a week prior. A similar trend has emerged in China, where Shanghai Futures Exchange stocks dropped nearly 20 percent. Interestingly, the United States is seeing the exact opposite trend, with inventories hitting record levels as traders scramble to import refined copper before a looming 15 percent tariff takes effect on January 1, 2027.
This frantic stockpiling in the U.S. comes amid broader instability across the global supply chain. Major mining operations are struggling to return to full capacity following a series of disasters. In Chile, Codelco has paused expansions at its El Teniente operation due to seismic risks following a fatal mine collapse last year. Meanwhile, heavyweights like Freeport McMoRan’s Grasberg mine and Ivanhoe Mines’ Kamoa Kakula project are still recovering from previous incidents and may not hit full output until 2027. Further complicating matters is a recent furnace failure at the Gresik smelter, which has knocked more available copper off the market for several weeks.
Adding fuel to the fire is the escalating conflict between the U.S. and Iran, now entering its seventh month. The closure of the Strait of Hormuz has constrained supplies of sulfuric acid essential for production while sending oil prices volatilely upward. Because copper production is energy intensive, analysts note that every jump in oil prices directly inflates operational costs for miners. With Brent crude climbing past 91 dollars a barrel recently, there is growing concern that these overhead costs will push copper contracts toward new all time highs on both the Comex and LME exchanges.
