Rare-earth demand is projected to grow substantially, but that does not guarantee a boom in prices, mining-company profits or returns for investors. The strongest case for growth is rising use of permanent magnets in electric vehicles, wind turbines, industrial motors and other technologies. The harder question is whether new mines, refineries and magnet plants can come online quickly enough—and profitably enough—to diversify a supply chain that remains highly concentrated.
What the rare-earth boom forecast actually says
The International Energy Agency’s (IEA) 2025 Stated Policies Scenario projects total rare-earth demand rising from 91 kilotonnes (kt) in 2024 to 123 kt in 2030 and 150 kt in 2040. These are scenario-based estimates for rare-earth elements as a group, covering clean-technology and other uses. They are not forecasts of an individual element’s price or a promise that announced projects will deliver the supply required. IEA, Rare earth elements 2025.
| IEA Stated Policies Scenario | 2024 | 2030 | 2040 |
|---|---|---|---|
| Clean-technology demand (kt) | 19 | 38 | 47 |
| Other demand (kt) | 72 | 85 | 103 |
| Total demand (kt) | 91 | 123 | 150 |
| Secondary supply and reuse (kt) | 27 | 32 | 43 |
| Primary supply requirement (kt) | 64 | 91 | 107 |
In this scenario, clean-technology demand doubles between 2024 and 2030, but it is not the whole story: other uses make up most projected demand in every year shown. The IEA’s figures also distinguish total demand from primary supply requirements; recycling and reuse contribute to supply, though they do not eliminate the need for newly mined material.
“Boom” is therefore best understood as a forecast of growing demand and strategic investment needs. The outcome for any company or commodity depends on which elements it can produce, where it sits in the value chain, project costs and delivery, customer demand, policy, substitution and recycling. Demand growth alone is not an investment case.

Why permanent magnets are central to the outlook
Permanent magnets are the fastest-growing and strategically most important rare-earth application, accounting for around 95% of rare-earth consumption by value, according to the IEA. Neodymium-iron-boron (NdFeB) magnets are among the strongest permanent magnets used in industry. They are primarily made with neodymium and praseodymium; dysprosium and terbium are often added to improve performance.
These magnets are used in electric vehicles, wind turbines, industrial motors, data centres, medical equipment, aerospace and defence. Automation, robotics and digital technologies could add to demand beyond 2030. But magnet-related elements are only a subset of the rare-earth market: growth in NdFeB magnets should not be mistaken for identical demand prospects for every rare earth.
From mine to magnet: where supply can get stuck
A mine announcement is not the same as a new source of finished magnets. Rare earths must pass through multiple stages, each with its own facilities, expertise, costs, environmental controls and potential bottlenecks:
- Extraction: ore or other mineral-bearing material is mined.
- Beneficiation and concentration: processing separates and upgrades the mineral-bearing material.
- Chemical upgrading and separation: processes produce individual rare-earth oxides from mixed material.
- Refining and metallisation: oxides are refined into metals.
- Alloying: metals are combined into materials suitable for magnets.
- Magnet manufacturing: alloys are made into finished magnets, including sintered permanent magnets.
Capacity at one stage does not guarantee capacity at the next. A diversified mine can still rely on concentrated refining, metal production or magnet manufacturing. The location and dependencies of each link matter when assessing whether a project can provide a buyer with a usable alternative.

How concentrated is rare-earth supply?
For the four magnet rare earths—neodymium, praseodymium, dysprosium and terbium—the IEA reports that China accounted for 60% of global mined production and 91% of refined output in 2024. China produced 94% of the world’s sintered permanent magnets that year, compared with around half in 2005. Those figures refer specifically to magnet rare earths and sintered magnets, not to every rare-earth product or every stage of the broader market. IEA, Executive summary — Rare Earth Elements.
Rank #2
The broader rare-earth series shows concentration at the top of the country rankings as well. In the IEA’s 2025 analysis, the top three countries accounted for 86% of mining in 2024 and 74% in its 2030 scenario; the corresponding shares for refining were 97% and 92%. These broader-series figures have a different scope from the China-specific magnet rare-earth and magnet-manufacturing shares above.
What export controls revealed about supply risk
In April 2025, China introduced export controls on seven heavy rare-earth elements, related compounds and magnets. The IEA reports that export volumes fell sharply in April and May; automakers in the United States, Europe and elsewhere had difficulty sourcing magnets, and some reduced factory utilisation or temporarily stopped production. Volumes recovered after licences were granted, but a premium remained for magnets made outside China. The episode illustrated how a disruption at a concentrated stage can affect manufacturers far downstream.
China announced expanded controls in October 2025, covering five additional elements and extending licensing requirements to certain internationally made parts, components and assemblies containing Chinese-sourced rare earths or made using Chinese technologies. The IEA’s 2026 outlook says the expanded measures were suspended for a year, until November 2026. That date is close, and the legal scope and status of trade measures can change; the suspension should not be treated as a permanent resolution. IEA, Executive summary — Global Critical Minerals Outlook 2026.
The IEA’s 2025 analysis estimated that, if the controls were fully implemented, downstream production worth USD 6.5 trillion per year outside China could be at risk, including more than USD 3 trillion in potential direct automotive losses. These are modelled exposure estimates under full implementation—not losses that occurred, and not probability-weighted forecasts.
Can new supply outside China catch up?
The IEA projects magnet rare-earth demand outside China to rise 50% by 2035 under its current-policy setting. Even when planned expansions are included, expected diversified capacity in 2035 covers only part of projected demand outside China. The measures below compare expected capacity with demand at each stage; they do not mean every announced facility will be built, operate at full output or have the right inputs available.

| Stage outside China | Expected coverage of projected 2035 demand | Additional expansion beyond planned capacity to fully cover projected needs |
|---|---|---|
| Mining | About 50% | Capacity would need to roughly double |
| Refining | About 25% | Capacity would need to quadruple |
| Magnet manufacturing | Well below 20% | Capacity would need to increase sixfold |
The IEA’s 2026 outlook adds a separate comparison: diversified refining capacity in place or announced is equivalent to around two-thirds of expected mined supply in 2035, while planned magnet production represents about one-third. These comparisons use different stages and denominators. They show that plans are advancing, not that all mine supply will be used or that announced facilities will be commissioned on schedule.
The project pipeline is also uneven. Projects announced by early 2026 represented more than 50 kt of planned diversified mining capacity by 2035, less than 40 kt of planned refining and separation, and around 18 kt of planned metals, alloys and finished magnets. These are planned-capacity figures, not verified production. The IEA estimates around USD 60 billion in investment over the next decade would be needed to meet demand in diversified regions, with nearly half for refining and about one-third for magnet manufacturing.

That can make financing harder precisely when projects need capital to reach commercial scale.

The IEA estimates recycling could reduce primary rare-earth supply requirements by up to 35% by 2050. Manufacturing scrap currently accounts for most secondary supply and is concentrated where magnets are made. As more electric-vehicle motors, wind turbines and electronics reach the end of their useful lives, they could provide additional material. The IEA projects Europe will generate half of global magnet scrap from wind and a quarter from EVs by 2030; these are projections, not guarantees of recovered or market-ready supply.
Turning scrap into usable material depends on collection, disassembly, separation technology, economics and recovery rates. The volume of material that could theoretically be recovered is not the same as the secondary supply actually produced. Recycling can reduce pressure for primary supply, but its contribution depends on putting the necessary collection and processing systems in place.

Environmental impacts also vary with geology, processing methods, jurisdiction and enforcement. The IEA describes acidic leachate and radioactive tailings associated with in-situ leaching of ionic-clay deposits; air emissions, toxic sludge and community-health pressures from chemical processing; and naturally occurring thorium and uranium that can become concentrated in tailings and residues. Those risks make water management, emissions, tailings, radioactive-material handling, permitting and community impacts material to evaluating a particular project. They should not be assumed to be identical across all deposits or producers.
What to examine when assessing a rare-earth project
For a reader weighing the financial significance of this sector, “rare-earth exposure” is too broad to evaluate on its own. A project’s stage, customer qualification, cost base and place in the chain can matter as much as the overall demand forecast. Useful questions include:
- What does the project actually produce? Distinguish mining, separation and refining, metal or alloy production, and finished magnets. Check which stages depend on other suppliers.
- Where is capacity located, and what inputs does it need? A facility may diversify one step while remaining dependent on concentrated sources for feedstock, technology or intermediate products.
- How mature is the project? Separate operating production from facilities under construction, funded or approved projects, announcements and conceptual plans. Capacity figures do not establish actual output.
- What is the element mix and co-product profile? Deposits produce different mixes; lower-value cerium and lanthanum co-products can affect project economics.
- Have customers qualified the material and committed to buy it? Testing, technical performance and offtake agreements can influence a project’s route to commercial operation and financing.
- Can the operation compete on cost and execution? Consider capital requirements, energy, feedstock, skilled labour, logistics, infrastructure and the ability to scale.
- How are environmental and community risks managed? Review water use, emissions, tailings, radioactive-material management, permitting and local impacts.
- What resilience does it add? Consider exposure to export controls, the availability of alternative suppliers and whether inventories or stockpiles could bridge a disruption.
- Is its recycling claim practical? Look for accessible scrap volumes and a workable processing route, and distinguish potential recoverable material from actual secondary supply.
What could strengthen or weaken the boom thesis?
The demand case is stronger if magnet use expands as projected and planned diversified facilities are financed, qualified by customers and brought into operation. Recycling could ease the need for new supply as end-of-life material becomes available. Conversely, delayed or uneconomic projects would leave concentration harder to reduce; substitution, weaker-than-expected adoption or other changes in demand could moderate growth. Policy shifts and trade controls may alter both costs and the value buyers place on alternative supply.
For personal-finance decisions, the central distinction is between a growing strategic need and an attractive investment outcome. The IEA’s outlook supports the first; it does not establish the second for any particular company, project or rare-earth element.
