USD Index fell 0.30% to 101.88 while copper prices slipped 0.78% to 6.5895 USD/lb and spodumene SC6 dropped 4.44% to 1290 USD/t, reflecting immediate pressure from physical supply constraints rather than broad macro moves. Oyu Tolgoi underground operations halted after the October 29 rockfall injuring 15 workers, while copper concentrate exports to China fell 70% over two weeks with daily truck convoys reduced from 13-15 to 3-4, creating an estimated 300 million USD revenue shortfall and potential 1.2 billion USD loss if sustained to year-end; Lynas simultaneously idled its Malaysian refinery kiln for one month and Mount Weld for two weeks. Rio Tinto and Lynas Rare Earths face the sharpest operational exposure through direct output losses at Oyu Tolgoi and the Malaysian/Western Australian facilities, with Tsingshan-linked Indonesian nickel assets also at risk if the reported 20-50% MHP and NPI cuts materialize.
