China's Rare Earth Processing Monopoly Unlikely to Be Broken Within a Decade

ING's latest report argues the real bottleneck in America's rare-earth supply chain is not mining but processing, heavy-rare-earth separation, and magnet manufacturing — China controls 91% of global refining and 94% of permanent-magnet output, a dominance that a decade of spending may not dislodge.
Where exactly is the US rare-earth problem?
ING analyst Ewa Manthey frames it bluntly: "The US rare-earth challenge is an industrial problem, not a geological one."
In plain terms = America has ore in the ground; what it lacks are the factories that turn ore into magnets.
Per the IEA, China accounts for roughly 60% of magnetic rare-earth mining, 91% of refining, and 94% of permanent-magnet production — the further downstream, the higher China's share.
This means → even if the US mines more, without processing capacity the ore stays raw material.
Why are heavy rare earths dysprosium and terbium the biggest gap?
Dysprosium and terbium — heavy rare earths that keep magnets stable at high temperatures — are critical to automotive, aerospace, and defense applications.
Production is overwhelmingly concentrated in China and Myanmar, with very few alternative sources.
MP Materials is developing a separation line targeting roughly 200 tonnes per year of dysprosium and terbium, but even if built, feedstock supply remains unresolved.
This reflects an awkward reality: you can build a separation plant, but you cannot build away the geographic concentration of the raw input.
How much has the US government spent — and what has it achieved?
Federal commitments to USA Rare Earth include $277 million in grants, $1.3 billion in priority guaranteed loans, and a 16% government equity stake.
MP Materials received federal investment plus a ten-year magnet procurement contract and a neodymium-praseodymium oxide price floor guarantee.
MP Materials, Vulcan Elements, and USA Rare Earth have each announced plans for 10,000-tonne-per-year magnet facilities.
But all of this is planned capacity — none has produced output yet. The money has arrived; the product has not.
Can the gap close within a decade?
The IEA estimates that by 2035, announced magnet-project capacity outside China will cover well under 20% of non-China market demand.
Barclays' head of global economics, Christian Keller, warns that China's "near-monopoly" in critical materials will persist at least through the end of this decade.
Bloomberg Intelligence analysts questioned whether over $40 billion in federal support can translate into reliable supply in the near term.
This means → even with full policy and capital commitment, the physical ramp-up cycle makes closing the gap within ten years unlikely.
What does this mean for the geopolitical contest?
The US Commerce Department last week announced restrictions on jet-engine parts exports to China, seen as retaliation against Beijing's weaponization of critical-material exports.
The US is also seeking alternative supply from Australia and Brazil and funding rare-earth recycling technology.
Analyst consensus, however, is that these measures are insufficient to break dependence on China within this decade.
In plain terms = the West is coming to terms with a hard reality — supply-chain rebuilding may not keep pace with the tempo of large-scale rearmament.
