Copper futures slipped to around $6.55 per pound on Monday, extending losses to a fourth consecutive session as a stronger dollar weighed on demand for the greenback-priced metal. The decline followed growing expectations that the Federal Reserve will raise interest rates next month after hawkish remarks from Chair Kevin Warsh. Supply conditions offered conflicting signals: the narrowing premium for spot copper over three-month futures and improving LME inventories suggested some easing, while shipments continued to be redirected toward the US ahead of potential new import tariffs. Mining disruptions in Indonesia, Congo and Chile added to global supply concerns.
