Overnight the USD Index rose to 100.75 while AUD/USD fell 0.41% to 0.697, weighing on USD-denominated prices and driving copper down 1.21% to 6.22 USD/lb and nickel 0.50% lower to 16504 USD/t with no offsetting mineral-specific catalysts. Critical minerals markets recorded zero mine outages, export bans, force majeure events or new Chinese licensing actions between 19-20 July 2026, leaving the sole material move as lithium hydroxide climbing 3.40% to 143750 CNY/t on thin volumes. ASX-exposed lithium and nickel producers with hydroxide and matte offtakes face direct margin pressure from the divergent price action while rare-earth names continue to operate under the unchanged 2025-2026 samarium-gadolinium export licensing regime.
