Chile's August copper export value fell to $4.62 billion, down 14%
month-on-month and 3.2% year-on-year, the lowest monthly level since July 2025,
central bank data showed. The drop came as the average August copper price was
more than 40% higher year-on-year. Heavy rain, snow and strong winds in July and
August disrupted mine operations, while rough seas periodically constrained port
activity. Chile produces about one-quarter of global mined copper; these
production setbacks are supporting copper prices and further tightening a global
supply picture already affected by outages elsewhere.
