Op-ed: It's time for U.S. to treat rare earth metals as instruments of geopolitical power. China already does

China's April 2025 rare earth export controls have exposed critical global supply chain vulnerabilities, given its dominance in mining (70%), refining (90%), and magnet production (92%) for essential technologies and defense. While a recent six-month reprieve allows license approvals, the deal lacks transparency on U.S. concessions and enforcement, and China's licensing process remains invasively data-intensive. This temporary measure underscores the urgent need for the U.S. and its G7 allies, as highlighted by their Critical Minerals Action Plan, to implement a coherent, long-term strategy to build secure, independent critical mineral supply chains, moving beyond short-term fixes to counter China's significant geopolitical leverage.

Analysis

China's April 2025 export controls on rare earth elements (REEs) and magnets have weaponized its strategic dominance over a critical global supply chain. Beijing controls approximately 70% of global REE mining, over 90% of refining, and 92% of high-performance magnet production, creating significant leverage over sectors from defense to electric vehicles. A recently brokered six-month trade framework, which resumes export licensing, is a fragile reprieve, not a solution. The deal's terms are opaque, and the U.S. defense sector remains excluded. Furthermore, China's licensing process is described as a form of "competitive surveillance," requiring firms to submit sensitive data, creating significant intellectual property and competitive risks. The tangible impact of this vulnerability was demonstrated by Ford's production halt at its Chicago plant due to a magnet shortage. While the U.S. and G7 allies are formulating responses, such as the Critical Minerals Action Plan and increased funding proposals, these efforts lag significantly behind China's decades-long strategic investment. U.S. firms like MP Materials are part of the solution but remain hampered by incomplete downstream processing capabilities, underscoring the immense challenge of building a secure, independent supply chain.

Key Decisions for Investors

• Investors should immediately assess portfolio exposure to industries with high dependency on Chinese rare earth magnets, including automotive, defense, and renewable energy, as the six-month licensing reprieve offers only temporary and uncertain supply stability.
• For companies directly impacted, such as those in the automotive and tech sectors, scrutinize supply chain resilience, inventory levels, and progress on sourcing from non-Chinese suppliers, as production halts like Ford's represent a material risk.
• While Western miners and processors like MP Materials are positioned to benefit from long-term onshoring trends, their near-term execution risk remains high due to downstream processing gaps and regulatory hurdles, warranting cautious evaluation.
• Monitor geopolitical developments closely over the next six months, specifically tracking the enforcement of the trade framework, potential Chinese retaliation against G7 members, and any concrete U.S. policy advancements on permitting reform and strategic funding, as these will be key catalysts for the sector.
