Read the scope beneath the chart
The IEA's 2026 rare-earth supply chart defines magnet rare earths and separates scenario-based primary requirements from total demand. Its notes account for secondary supply and refining losses, showing why the chart's boundary matters as much as its headline values.
Record the publication edition, target year, elements and material basis. Do not compare an all-rare-earth total with a magnet-element scenario as if they measure the same market. Scenario labels also need their definitions from the relevant edition rather than assumptions carried over from an older report.

Identify what causes the difference
Break the scenario into activity levels, technology choices and material intensity where the source allows. More vehicles or equipment do not necessarily imply proportionately more of every rare earth if design choices or per-unit requirements change. Recycling assumptions can also alter the requirement for primary material.
For an industrial decision, connect the market view to the actual product and stage. A long-term aggregate requirement does not establish near-term demand for one supplier's specification. Keep the scenario as context and investigate the named route, customer and execution evidence separately.
A useful sensitivity exercise
In a hypothetical case, unit demand increases by 20% while material required per unit falls by 10%. Material demand becomes 1.2 multiplied by 0.9, or 1.08 times the original amount: an 8% increase before other changes. Showing the assumptions makes the conclusion more useful than repeating the 20% headline as a mineral-demand forecast.
Before comparing two demand numbers
| Field | Check |
|---|---|
| Scope | Same elements and product basis? |
| Scenario | Same policy and technology assumptions? |
| Supply requirement | Total demand or primary material after recycling? |
Your review checklist
- Record the source edition and target year.
- Match the material boundaries.
- Separate intensity from activity growth.
- Connect market context to product-specific evidence.

Is a scenario a probability-weighted forecast?
Not necessarily. Use the publisher’s definition rather than assigning probabilities to scenario labels.
Can growing demand prove one project will succeed?
No. Product fit, cost, timing, execution and commercial access still require project-level investigation.
