Chile Copper Output Falls Most Since 2017

2026-10-30 12:05 By Agna Gabriel 1 min. read

Chile’s copper production plunged 15.1% year-on-year to 387.87 metric tons in September 2026, marking its steepest decline since March 2017 and the third consecutive monthly fall.

Finance Minister Jorge Quiroz warned that output could fall by 8% to 9% this year, worsening his previous forecast of a 7% contraction and putting the world’s largest copper producer on track for its weakest annual production in more than two decades.

The decline reflects fatal mining accidents, extreme weather, operational disruptions and years of underinvestment, which have left aging mines struggling with deteriorating ore grades.

The supply shortfall is adding to tightening conditions in the global copper market, where demand is rising due to investment in data centers and power infrastructure.

Although mining investment projects are increasing, their contribution to output will take time to materialize.

Chile Copper Output Drops in July
Chile’s copper production fell 9.4% year-on-year to 403,424 metric tons in July 2026, reversing a 5.1% increase in June. The decline was attributed to unfavorable weather conditions in northern Chile that disrupted production, as well as maintenance work at major mining operations. The sharp drop in output from Chile, the world’s largest copper producer, added to concerns over tightening global copper supplies.
