Stifel outlines critical minerals investment thesis amid China export controls

Stifel published a note on September 27, 2026, titled "National Security Critical Materials & Supply Chain: Own the Bottlenecks." The report argues that China's tightening export controls are creating an urgent need for stable critical materials production outside of its borders. The analysis suggests that a strong defense cycle combined with committed support from the US customer base structurally improves growth for producers in this sector.

The report highlights that China is a top-four supplier for 14 of 31 minerals and the single largest for eight. The findings suggest that the global critical minerals supply chain is undergoing a strategic shift away from reliance on China due to geopolitical pressures and US defense industry requirements.
