China's Rare Earth Export Controls Highlight US Supply Chain Vulnerabilities
Key points
- China uses rare earth export controls as leverage, even during trade truces.
- US companies MP Materials and USA Rare Earth were placed on an export control list.
- US efforts to rebuild supply chains lack scale and durability despite available capital.
- Authors propose a contingent convertible security to incentivize private investment.
China's Export Control Strategy
Since October 2025, Beijing has implemented sweeping controls on rare earth exports, which have been temporarily suspended multiple times, most recently until November 10, with a broader trade truce through January 10, 2027. These reprieves have consistently followed American concessions, underscoring China's significant leverage in the rare earth market. Even during these truces, China has restricted sales, leaving buyers with limited options.
Impact on US Supply Chain Efforts
In June, while a suspension was in force, China placed MP Materials and USA Rare Earth, two key US companies intended to establish an alternative rare earth supply, on an export control list. This action directly impacts Washington's strategy to reduce reliance on Chinese rare earths.
Challenges in US Rebuilding Efforts
The United States has allocated up to $100 billion in loan authority for critical minerals through the One Big Beautiful Bill Act, indicating sufficient capital. However, the effort to rebuild the supply chain has not achieved the necessary scale or durability. The primary obstacles are a lack of alignment among stakeholders and insufficient political patience for the decade-plus timeline required to reconstruct a complex supply chain.
Market Failure and Proposed Solutions
The current situation is described as a market failure, where capital markets efficiently finance supply but struggle to insure against a monopolistic state seller capable of manipulating price and availability. Existing US government tools, which are market-based, are deemed insufficient to incentivize private investors in this environment. The authors propose a contingent convertible security that would convert into ownership if China weaponizes its supply, aiming to overcome both economic and political hurdles.
Historical Context of China's Dominance
China's strategic focus on industrial capacity, including rare earths, dates back to Deng Xiaoping's 1964 directive to develop the world's largest rare earth deposit near the Mongolian border. This long-term commitment has contributed to China's current dominant position in the global rare earth market.

Reporting from
China has repeatedly imposed and suspended rare earth export controls, demonstrating its leverage and hindering US efforts to build alternative supply chains. Despite significant US funding allocated for critical minerals, a lack of aligned interests and long-term political commitment impedes progress in establishing a resilient supply.
