The Magnet Gap: U.S. and European Automakers Enter the REEx Transition Vulnerability Window

Highlights

• China supplied ~94% of global sintered permanent magnets in 2024, giving Beijing leverage it has already exercised through 2025 export controls that disrupted automaker production.
• GM, Ford, Stellantis, Rivian and Lucid all show significant rare-earth magnet exposure, with GM's VAC contract termination illustrating how even federally backed supply deals can collapse.
• Automotive qualification processes APQP and PPAP mean a new magnet factory cannot automatically replace a qualified Chinese supplier—validation alone can take years.
• BMW and Renault offer the most credible near-term escape by engineering electrically excited synchronous motors that eliminate permanent rare-earth magnets from traction drives.
• REEx forecasts broad automotive independence from Chinese rare-earth magnets is unlikely before late 2020s and more realistically 2030 and beyond for high-volume programs.
