Overnight macro showed the USD Index at 101.73 down 0.14 percent and S&P 500 at 7580 down 1.82 percent, yet nickel rose 2.10 percent to 15540 USD/t and copper 1.28 percent to 6.541 USD/lb, indicating selective strength in base metals despite equity weakness. Rio Tinto restarted underground operations at Oyu Tolgoi after the October 29 rockfall, with the mine running at a 450000 tonnes per year copper rate in Q3 2026; surface milling continued but Ganqimaodu border delays have cut truck availability for concentrate shipments with no production loss tonnage released. ASX-listed Rio Tinto faces direct exposure through ongoing Oyu Tolgoi logistics constraints while Chinese battery makers CATL and BYD captured 73 percent of January-September 2026 EV installations at 994.5 GWh total.
