Rare Earth Elements (REEs): Overview — Uses, Supply Risks & Investment Signals
Why REEs power the green transition and modern defense, why supply is dangerously concentrated, and what signals matter for investors and policymakers.
- What: REEs are 17 elements vital for magnets, electronics, renewables, and defense tech.
- Why it matters: China controls ~90% of refining and magnet-making capacity.
- Investor cue: Monitor NdPr/Dy/Tb prices, export curbs, and stockpile news.
- Neodymium (Nd), Praseodymium (Pr): EV motors, wind turbines, HDDs.
- Dysprosium (Dy), Terbium (Tb): Heat-resistant magnets for defense & EVs.
- Cerium (Ce), Lanthanum (La): Catalysts, glass polishing, converters.
- Europium (Eu), Yttrium (Y): LEDs, sensors, superconductors.
- Other critical uses: Lasers, radar, guidance, optical fibers, nuclear rods.
Production is concentrated; demand is booming from EVs and wind energy.
| Metric | Highlight |
|---|---|
| 2023 Output | ~350,000 t REO; China ≈68%, U.S. ≈12%, Myanmar & Australia follow. |
| Major Reserves | Australia 105 M t, China 44 M t, Vietnam 22 M t, Brazil 21 M t. |
| Value Share | Magnet REEs (Nd, Pr, Dy, Tb) = 30% volume but >80% market value. |
| Growth Outlook | Magnet demand may triple by 2035, led by EVs and renewables. |
- China’s dominance: Mines >50%, refines ~90% of global REEs → leverage in global tech chains.
- Export curbs (2025): Restrictions on NdFeB magnets hit global EV supply chains.
- Myanmar conflict: Heavy-REE flow (Dy/Tb) disrupted by fighting in Kachin region.
- Environmental limits: Non-China projects face costly permitting & waste handling.
- Processing gap: Few separation plants outside China → major bottleneck.
- 2025 Prices: NdPr oxide ~$150/kg (+56% YTD), Dy ~$454/kg (+29%), Tb ~$1,983/kg (+42%).
- Forecast: Analysts expect long-term tightness unless new refining ramps up.
- Volatility: Price gap widening between China and overseas markets.
- India: Building critical-minerals stockpile, magnet incentives (₹7,300 cr plan).
- U.S.: $7.5 bn funding + Pentagon purchases to secure defense supply chains.
- EU: Joint REE reserves proposed, funding 13 strategic raw-material projects.
- Alliances: U.S.–India, Quad & EU partnerships to diversify REE refining.
- Top Producers: MP Materials (U.S.), Lynas (Australia), Iluka, Arafura, Greenland Minerals.
- ETFs: VanEck REMX — diversified REE/battery-metal exposure.
- Risks: Policy shifts, environmental delays, financing & over-capacity risks.
