Strategists report that a severe storm sweeping through Chile's copper mines, causing production disruptions, could intensify the already tight market supply-demand dynamic. As the United States and China compete for this critical industrial metal, the tug-of-war over supply is further pushing up copper prices.
While the near-term production halt appears limited in scale, strategists note that the mining disruptions in Chile coincide with a confluence of bearish factors in the market. Chile accounts for more than one-fifth of global copper production, and the market is already under pressure from multiple influences: expectations of new U.S. tariffs, coupled with a surge in refined copper demand driven by power grids and artificial intelligence infrastructure.
Over the past week, blizzards, flash floods, and fierce winds have struck this South American nation, resulting in 13 fatalities. Operations at top producers, including Anglo American, Antofagasta, Lundin Mining, and Chile's state-owned copper producer Codelco, have been disrupted.
London-listed Chilean mining giant Antofagasta has suspended mining and smelting operations at its Los Pelambres mine. Toronto-based global miner Barrick Gold has evacuated employees from its sites due to the extreme weather.
Lundin Mining stated on Monday that its Caserones copper mine in the Atacama region of northern Chile is expected to take two to three weeks to resume production. The blizzard damaged the mine's power lines, and the Vancouver-based company suspended operations on July 18. Rainfall also affected Lundin Mining's Candelaria copper mine, though it continued processing using existing ore stockpiles before later returning to full capacity.
Amid rising concerns over a global supply shortage, copper prices have surged in recent years, hitting an all-time high of $6.70 per pound ($13,643 per tonne) on June 2. Strategists warn that if the winter storm drags on and continues to hamper Chilean copper output, prices could face further upward pressure.
The construction of AI data centers, along with the production of smartphones, electric vehicles, home appliances, and industrial machinery, are all heavily reliant on copper. Higher copper prices will increase production costs across these industries.
