Copper Prices Surge as Supply Chain Constraints Tighten

On the London Metal Exchange, prices recently touched $14,300 a ton, while Comex contracts hit an all-time high of $6.70 a pound in August. Warehouse stocks have drained for 42 consecutive days, with nearly half of the remaining metal already earmarked for withdrawal. This volatility stems from a year-long production crisis triggered by a fatal flood at Freeport-McMoRan’s Grasberg mine in Indonesia, which crippled output and forced a reduction in 2026 guidance by roughly one-third. Recovery at the site remains stalled until at least 2027.

Broader structural issues compound the problem. International Copper Study Group data indicates a 1.1% drop in global mine output during the first half of the year, with Chile’s production reaching its lowest second-quarter levels in nearly two decades. Industry veterans point to aging assets and falling ore grades as primary obstacles to rapid replenishment. Meanwhile, U.S. traders are aggressively stockpiling, importing a record 200,000 tons in July to front-run potential 15% tariffs. Despite rising scrap usage, analysts at Citigroup suggest prices could reach $15,000 a ton by year-end, provided that manufacturing demand continues to outpace the industry's ability to extract new metal.
