USD Index at 99.97 and CNY/USD at 6.7423 showed negligible overnight shifts, leaving critical minerals prices largely range-bound with only tungsten posting a 23.10% decline to 891.43 USD/mtu. Copper eased 0.21% to 6.583 USD/lb despite S&P 500 gains of 0.65%. Antofagasta cut full-year 2026 copper guidance by up to 45,000 tonnes to 625,000–655,000 tonnes after weather-driven shutdowns at Los Pelambres reduced H1 output 9% to 285,000 tonnes, while Antaike flagged Chinese refined copper output falling for a second month on feedstock shortages with treatment charges at minus $175.7 per tonne. Antofagasta shares on the LSE face immediate volume exposure from the Los Pelambres curtailment and pipeline repairs, while ASX copper names linked to concentrate markets absorb the downstream impact of record-low Chinese treatment charges.
