Copper Hit a Record High as Chile Posts Its Weakest Output in 19 Years

London Metal Exchange three-month copper touched an intraday all-time high of $14,694 per tonne on September 8, 2026, surpassing the previous record of $14,527.50 set in January. The metal has come a long way in eight months, and the reason is not a demand surprise. Chile, the world's dominant producer, reported its weakest second-quarter output in at least 19 years and has now cut its full-year production forecast for a second consecutive quarter, projecting a 2.6% annual decline.
