Battlefield rare earths: How the U.S. lost to China

What It Covers

Planet Money traces how the U.S. rare earths industry collapsed from a Molycorp monopoly at California's Mountain Pass mine in the 1960s to China controlling 90% of global processing today, and examines the U.S. government's current multi-billion dollar effort to rebuild domestic rare earth supply chains.

Key Questions Answered

• •Industrial policy replication: China's rare earths dominance was built through four specific policy levers: preferential low-cost government financing, domestic processing mandates blocking raw ore exports, foreign company restrictions requiring in-China facilities, and state-funded scientist training programs. The U.S. is now deploying the same playbook — government loans, grants, equity stakes, and coordinated price floors with Japan, Mexico, and Europe.
• •Price weaponization risk: When Molycorp announced plans to double Mountain Pass output to 40,000 tons in 2010, China flooded global markets with rare earth supply, crashing prices and bankrupting Molycorp. Any company rebuilding domestic rare earth capacity should anticipate deliberate price suppression from state-backed Chinese producers and secure government price floor agreements before scaling production.
• •Processing is the strategic chokepoint: Mining rare earth ore is not the hard part — refining it into usable materials is where China's dominance is most entrenched. Mountain Pass mine, even after reopening, shipped raw ore to China for processing until 2024. Building domestic refining capacity, not just mining, is the critical gap the U.S. must close to achieve genuine supply chain independence.
• •Dependency exposure timeline: China's 2010 informal rare earth export ban against Japan — triggered by a fishing boat arrest dispute — cut off Japanese car and electronics manufacturers within weeks, causing prices to spike 600–700%. Supply chain managers in defense, automotive, and consumer electronics should audit rare earth dependencies and map which specific elements, like neodymium or terbium, lack non-Chinese sourcing alternatives.
• •Phased expansion discipline: Molycorp CEO Mark Smith identifies the single strategic error that destroyed the company: announcing a capacity doubling to 40,000 tons before Phase 1 operations were stable and proven. For capital-intensive resource projects, validating and optimizing initial production capacity before publicly committing to expansion prevents triggering competitive retaliation before the business has sufficient financial resilience.
