Chile’s copper production contracted further in March 2026, underscoring mounting pressure on the world’s largest copper producer. According to the latest data updated on 30 April 2026, output fell 9.0% year-on-year in March, a sharper decline than February’s 4.8% year-on-year drop.

The figures, measured on a year-over-year basis, show that the pace of contraction in Chilean copper production nearly doubled in just one month. February 2026 had already marked a negative comparison against February 2025, and March extended that trend, with production levels falling more steeply compared with March 2025.

The deepening downturn in March raises concerns for global copper markets, where Chile plays a pivotal supply role. While the data do not specify underlying causes, the worsening year-on-year performance could amplify market focus on Chilean output trends in the coming months.
