At a glance: The critical-minerals shortage is not one single shortage. Different minerals, processing steps and export rules create separate vulnerabilities for batteries, chips, electric motors and defence equipment.
First, do not confuse lithium with rare earths
Lithium is central to many rechargeable battery chemistries, while rare earth elements such as neodymium, praseodymium, dysprosium and terbium are vital to high-performance permanent magnets. Gallium and germanium are separate strategic materials used in specialized semiconductor and optical supply chains; graphite is used in many battery anodes. Treating all of them as a single commodity hides where the actual bottleneck sits.
| Material group | Important use | Typical chokepoint |
|---|---|---|
| Magnet rare earths | Electric motors, wind turbines, defence components | Separation, metal/alloy making and magnet manufacturing |
| Lithium | Lithium-ion batteries for vehicles and storage | Chemical refining and battery-grade conversion |
| Graphite | Battery anodes | Battery-grade purification and anode processing |
| Gallium / germanium | Selected semiconductors, electronics and optics | High-purity refining and export licensing |
What China’s controls mean in 2026
The International Energy Agency says export curbs announced in April 2025 disrupted rare-earth magnet supplies and forced some automakers to reduce or temporarily pause production. Broader measures announced in October 2025 were suspended for a year in November 2025, rather than taking full effect immediately. Export licensing and concentrated processing capacity still create commercial risks even when implementation is delayed.
The IEA estimated that full implementation of the more expansive restrictions could expose up to $6.5 trillion of annual downstream production outside China to risk. That is a scenario-based measure of exposed economic activity—not a prediction that $6.5 trillion has already been lost.
Why chip supply chains are not just about chips
Semiconductor fabs depend on specialty gases, high-purity inputs, precision tools and globally distributed components. Some products use gallium or germanium; others depend indirectly on rare-earth-containing motors and equipment. A hold-up in one small component can interrupt an expensive manufacturing line even if the core silicon wafers are available.
A global response is under way
In October 2026 the European Commission selected 46 additional strategic raw-material projects for streamlined support under its Critical Raw Materials Act, according to Reuters. Such project designations can reduce permitting friction, but they do not create immediate processing output. India is also considering mineral stockpiling as a buffer against disruption. New mines, refining capacity and qualified suppliers require years of work.
The price impact passes through several layers
- Export controls and licences can add delay and uncertainty before a shipment moves.
- Scarce qualified alternatives may charge a supply-security premium.
- Manufacturers may increase inventories, redesign components or diversify geographically.
- Ultimately, price or delivery changes may affect electronics, EVs and industrial equipment—but the size depends on each product’s actual material exposure.
How procurement teams can respond
Map critical materials down to the component and sub-tier supplier. Ask where refining and separation occur, not merely where an item ships from. Maintain approved alternatives, realistic qualification timelines, a buffer stock policy and product-design fallbacks. Track policy changes from official trade authorities rather than relying on viral claims about blanket bans.
What to watch next
The next meaningful indicators are new licensing decisions, the commercial ramp-up of non-Chinese separation and magnet plants, battery-grade material capacity, and the actual throughput of newly selected European projects. A project announcement is not equivalent to secure supply.

Frequently asked questions
Are rare earths and lithium the same materials?
No. Lithium is an alkali metal; rare earths are a distinct group of elements with different uses.
Did the IEA report a realised $6.5 trillion loss?
No. It described production potentially at risk in a severe restrictions scenario.
