Pentagon’s aluminium squeeze deepens as 60% U.S. import reliance meets years-long build times

AI Market Summary
U.S. defense-driven demand for high-purity aluminium is colliding with limited domestic capacity and multi-year timelines for new smelters, keeping near-term supply tight. Disruption to a key UAE supplier highlights import fragility, while tariffs have not materially closed the supply gap as U.S. import dependence remains high. Elevated Midwest physical premiums signal ongoing scarcity, supporting aluminium market tightness despite policy incentives and potential Canadian prioritization.

The U.S. defense sector has an urgent need for high-purity aluminium, but domestic capacity is limited and new facilities take years to come online. The United States relied on imports for 60% of its aluminium last year, and high-purity supplies have become more exposed after an attack on a key supplier. Tariffs have only modestly lifted output, leaving a large domestic shortfall, while Canada could offer a short-term backstop. The federal government has committed $500 million to support related projects.
