FX.co ★ Chile’s Copper Slump Deepens in September as Output Falls 15.1% YoY

Chile’s copper production downturn intensified in September 2026, with output contracting 15.1% year-over-year, according to data updated on 30 October 2026. The latest figure marks a sharper decline than in August 2026, when production was down 12.8% compared with the same month a year earlier.

The data highlight a worsening trend in the world’s largest copper producer, as the year-over-year contraction in September exceeded the previous month’s fall. The “actual” indicator reflects the change in copper production in September 2026 versus September 2025, while the “previous” figure captures the change in August 2026 versus August 2025.

The deepening decline underscores mounting pressure on Chile’s mining sector and may have implications for global copper markets, which are highly sensitive to Chilean supply dynamics.
