World Copper Giant’s Alarm Bell; Chile’s Production Decline and Continued Supply Tightness

مس شیلی

Chile, the world's largest copper supplier with over 20% share of global supply, after recording a historic two-decade production low, has announced a slow and fragile recovery of this red metal’s production next year; an event influenced by ore grade decline in aging mines and climate crises, keeping the global refined copper market in a critical phase amid a surge in energy transition demand and on the brink of a supply deficit.

News Base «Madan Name»: The Chilean government copper commission (Cochilco) in its latest report downgraded this country’s copper production estimate for the current year by 8.4% to 4.94 million tons and forecasted that production in 2027 would improve mildly by only 3% to 5.08 million tons; a figure that still remains considerably below the country’s previous records and capacities.

Grade decline in mining giants; main cause of production fall

According to Cochilco data, Chile’s copper production in the quarter ending in September has dropped to the lowest seasonal level in two decades. The focus of this decline has been the large complexes managed by the companies “Codelco” and “BHP Group,” which alone accounted for 77% of the net production decline. Analysts attribute the primary reason for this protracted trend to a sharp drop in ore grade, complex geological challenges, and frequent operational stoppages.

Minimal safety margin in the global copper market

Despite the slow recovery trend, Chile alongside the Democratic Republic of Congo is expected to contribute a 37% share of the estimated 3.4% growth in global copper supply next year. However, Cochilco has warned that the refined cathode copper market will remain extremely tight; with a supply surplus next year equal to only 0.8% of the total estimated consumption, representing a fragile safety margin against operational risks or a surge in electric vehicle industry demand.
