Chile’s copper production contraction intensified in August 2026, with output declining 12.8% year-on-year, according to data updated on 30 September 2026. The latest figure marks a sharper fall than in July 2026, when production was down 9.4% compared with July a year earlier.
The data are based on year-over-year comparisons, measuring the percentage change in copper production in a given month relative to the same month of the previous year. The deepening decline from July to August signals mounting pressure on Chile’s key export sector and may raise concerns over supply conditions in global copper markets. Investors and analysts will now be watching upcoming monthly releases to see whether the downturn stabilizes or continues to worsen into the final months of 2026.
