USD Index at 99.83 and CNY/USD at 6.745 showed negligible overnight shifts, leaving critical minerals prices driven by physical supply rather than currency or equity macro flows. Copper held near record levels above $14,000/t as the sole Tier-1 event dominated pricing. Indonesia’s Gresik smelter, jointly owned by Mitsubishi Materials and PT Freeport Indonesia and processing Grasberg ore, halted operations on August 8-9 due to a boiler leak with no restart date, directly tightening refined copper availability from the combined 400kt cathode capacity of Gresik and Manyar. Freeport-McMoRan’s Grasberg output recovery from the 2025 mudslide remains on track for end-2027 only, amplifying the refined supply gap. ASX-listed copper producers with Indonesian offtake exposure face immediate contract delays while tungsten prices jumped 9.60% to 665.57 USD/mtu on separate supply tightness unrelated to the copper outage.
