Tearing apart the rare earth magnet supply chain

Rare earth magnets.

The financial press moved on three months ago. Bloomberg ran its "rare earth truce holds" headline in May. CNBC covered the October 2025 Trump-Xi summit as a diplomatic breakthrough. Canada's Prime Minister Mark Carney called his own meeting with Xi "a turning point for critical mineral supply chains." The consensus, as usual, is comfortable: crisis averted, supply chains stabilizing, move along.

Nobody is looking at the export data.

China imposed licensing controls on seven heavy rare earths — dysprosium, terbium, yttrium, samarium, gadolinium, lutetium, scandium — in April 2025. Reimposed stricter controls in October. Then suspended the October package under a diplomatic truce through November 10, 2026. The headlines said "resolved." But the April controls were never lifted. Export license approval rates for European firms are running below 25%, with two-to-three-month processing windows. The truce didn't reopen the valve. It just gave the valve a nicer name.

The result is a market that has fractured into two separate worlds. Inside China, rare earth prices are stable enough to look normal. Outside China, dysprosium trades at four to five times the domestic Chinese price. Yttrium oxide went from single digits per kilogram to $1,100. That's not a supply chain adjustment. That's a structural severance.

And the truce that was supposed to fix it expires in 82 days.

Here's what the machine actually looks like.

China mines roughly 60–70% of global rare earths. That number gets cited a lot, and it's the least important one. What matters is downstream: China controls over 90% of oxide separation, metal refining, and — critically — around 94% of permanent magnet manufacturing. The magnets are what go into the things that matter. Every EV traction motor. Every offshore wind turbine generator. Every F-35 flight-control actuator and Tomahawk guidance package.

NdPr alloy — the primary neodymium-praseodymium alloy for NdFeB permanent magnets — opened 2026 at approximately $53 per kilogram. It reached roughly $138 by late April and sits near $133 as of early August. China's Rare Earth Price Index reads 259.1. That number is meaningless to anyone buying outside the Chinese border.

The ex-China price for dysprosium and terbium runs four-to-five times higher than domestic Chinese quotes. Japan's dysprosium imports fell 82% in the first half of 2026. Yttrium exports to the United States collapsed from 333 tonnes in the eight months before the April 2025 controls to 17 tonnes in the eight months after. That's a 95% cut in physical flow — during a "truce."

The NdPr market is forecast to remain in deficit for the second consecutive year. Even with emerging ex-China supply from MP Materials and Lynas, output cannot keep pace with demand from 22.9 million EVs projected for 2026, plus the offshore wind buildout, plus defense procurement. Each EV uses roughly 1.5 kilograms of NdFeB magnets. Each large offshore turbine requires 600 to 900 kilograms of neodymium and dysprosium. An F-35 carries approximately 50 pounds of rare earth materials.

There is no substitute at scale. Not yet. Not for years.

Eighty-two days.

That's what's left on the Trump-Xi truce clock. The suspension of China's October 2025 export controls — the ones that included a foreign direct product rule barring re-export of anything containing Chinese rare earths without Beijing's approval — runs out on November 10, 2026. No extension has been confirmed. No diplomatic framework is in place to negotiate one. The financial press is treating continuity as the base case. I've watched enough of these expiry dates to know that the market never prices the tail risk until it's too late.

Here's what the machines are missing. The April 2025 licensing regime is still fully operational. Even during the truce, export license approval rates for European firms have run below 25%. Chinese magnet makers — JL MAG, Ningbo Yunsheng, Zhong Ke San Huan — got streamlined "general licenses." Everyone else is in the queue. Western aerospace manufacturers have flagged that they are rationing yttrium for thermal barrier coatings on jet engine turbine blades. Honda paused production at factories in Japan and China in January over semiconductor shortages.

Analysis suggests F-35 deliveries could undershoot planned numbers by 20 to 30 percent if the full licensing regime snaps back. That's not a trade dispute. That's a defense procurement crisis with a countdown timer.

And the Western alternative supply chain? The U.S. government has committed $7.3 billion across five agencies. MP Materials' 10X magnet facility doesn't commission until 2028. Lynas produced eight tonnes of dysprosium and terbium last quarter. Eight tonnes. Global demand runs in the thousands of tonnes per year. The DOD set a $110/kg NdPr price floor for MP Materials and took a 15% equity stake — bold industrial policy by any measure, and still years from producing at the scale that matters.

I've watched policymakers declare supply chain independence while the actual tonnage tells a different story. The gap between the announcements and the atoms is measured in years, not quarters. November 10 is a cliff, not a deadline.

The sequence is mechanical. If the truce lapses without extension — or if extension comes with tighter conditions, which is what the October 2025 precedent suggests — the foreign direct product rule reactivates. That means any product containing Chinese-sourced rare earths can't be re-exported without Beijing's sign-off. The compliance burden alone freezes procurement cycles.

First wave: defense contractors scramble to certify alternative magnet sources. Lead times extend. F-35 delivery schedules slip further. Second wave: EV OEMs who locked in Chinese magnet supply on long-term contracts discover those contracts are subject to export approval that may not come. Production pauses ripple through the supply chain — again. Honda already showed us what that looks like in January.

Third wave: the market finally prices the structural deficit. NdPr moves past $150. Heavy rare earth premiums outside China go vertical. And then everyone writes the headline that should have been written six months ago.

Where does capital go? Not into the broad rare earth ETFs — those are diluted with junior explorers five years from first production and companies with deposits but no processing capability. The edge, if there is one, sits with the vertically integrated plays: companies that mine, separate, refine, and manufacture magnets under a single non-Chinese jurisdiction. MP Materials with its Mountain Pass mine and Independence magnet facility. Lynas with its Australian mine and Malaysian processing. USA Rare Earth building a mine-to-magnet chain across Texas and Oklahoma.

The $7.3 billion the U.S. government deployed isn't charity. It's an admission that the market, left alone, cannot close this gap in time. And "in time" is November 10.

Financial press says truce. Physical market says fracture. In 82 days, we find out which one was right. I know where my attention is.
