Rare Earth Investment Risks: What Can Go Wrong
The main risks of investing in rare earths are price volatility, China's control of processing and export policy, delays and financing needs at new projects, substitution by rare-earth-free magnets, and thin trading in smaller stocks and funds. The table sets out each risk with the evidence behind it and where to read more.
| Risk | What the evidence shows | Read more |
|---|---|---|
| Price volatility | USGS annual averages for neodymium oxide were $134/kg in 2022 and $56/kg in 2024, a fall of more than half; the 2025 estimate is $73/kg. Producer earnings and share prices swing with it. | Price charts |
| China controls processing | The IEA estimates that China accounts for around 90% of rare earth refining. New capacity outside China takes years to permit, build and ramp up. | Separation and refining |
| Export controls and policy change | China introduced export licensing for several medium and heavy rare earths in April 2025, and later measures have been suspended and reinstated. Rules can change on short notice, in either direction. | Export controls timeline |
| Two-tier prices and ex-China oversupply | Heavy rare earths cost several times more outside China, while Benchmark reported ex-China NdPr falling below $110/kg in 2026 on oversupply of light rare earths. A company's revenue depends on which tier it sells into. | China vs ex-China prices |
| Project execution and financing | Several Western separation plants are not planned to reach full output until 2027 or later, for example Iluka at Eneabba and Ucore in Louisiana. Delays, cost overruns and new share issues are common risks for developers. | Due diligence checklist |
| Government support is contract-specific | Price floors protect only the producers that hold them, for the volumes and terms in the contract. Arafura has a non-binding letter of support, not a floor. | Price floors |
| Substitution | BMW and Renault already build rare-earth-free motors, and Niron Magnetics expects its iron nitride magnet plant in Minnesota to start production in 2027. NdFeB still dominates, but substitution is a long-term risk to demand. | Rare-earth-free magnets |
| Liquidity | Rare earth funds are small: as of October 2026 REMX held $1.48 billion, and the other US-listed funds compared on this site held between about $3.7 million and $66.5 million. Smaller stocks can also trade thinly, with wide bid-ask spreads. | Rare earth ETFs compared |
| Environmental and permitting | Monazite and some other ores contain thorium and uranium, which end up in processing residues. Permitting, waste storage and public opposition can delay or stop projects. | Environmental and ESG |

Managing Rare Earth Investment Risk
No approach removes these risks, but they can be sized and spread:
- Size for a deep fall. Hold only what you could watch fall by more than half. See portfolio construction.
- Spread across stage and region. Combine producers, processors and funds rather than relying on one project.
- Read the contracts. Check whether a company has signed offtakes or a price floor, or only a letter of support or intent. The due diligence checklist lists what to check.
- Use funds for liquidity. Funds spread single-company risk, but check assets, volume and spreads first, since most rare earth funds are small.
- Track policy. Re-check export control status when rules or suspension dates change.
Rare Earth Investment Risks FAQ
What are the main risks of investing in rare earths?
The main risks of investing in rare earths are price volatility, China's control of processing and export policy, project delays and financing needs for new producers, substitution by rare-earth-free magnets and motors, and thin trading in smaller stocks and funds.
Are rare earth stocks volatile?
Yes. USGS annual averages for neodymium oxide fell from $134/kg in 2022 to $56/kg in 2024, and rare earth stock prices often move further than the underlying price. Size any position so that a fall of more than half would not derail your wider plans.
Does a price floor remove the risk of investing in a rare earth company?
No. A price floor protects against a fall in the price of the covered product, for the volumes and years in the contract. It does not cover production problems, cost overruns, share dilution or political change.
Could rare-earth-free magnets replace NdFeB?
Not soon, but it is a long-term risk. Some carmakers already use rare-earth-free motors, and iron nitride magnets are due in commercial volume from 2027, but NdFeB magnets still dominate EV and wind applications.
