Overnight USD Index rose 0.20% to 100.42 while copper climbed 2.53% to 6.7825 USD/lb and cobalt eased 0.85% to 39780 USD/t, reflecting immediate supply-side pressure from multiple mine and smelter constraints rather than broad macro flows. Freeport Indonesia extended the Grasberg Block Cave full production restart to early 2028 after the September 2025 mudflow, holding output at 40-50% of capacity and removing several hundred thousand tonnes of annual copper supply; concurrent DRC chemical shipment cancellations of 3800 tonnes SMBS plus Zambia’s extended Mopani and Chambishi smelter outages tightening 2 million tonnes of sulfuric acid output have compounded the copper-cobalt squeeze. Northern Graphite’s Lac des Îles lease suspension in Quebec delays North America’s sole commercial flake graphite restart beyond the prior Q3 2026 target, exposing battery supply chains already facing Chinese export controls through November 2026.
