Critical-mineral export controls and the energy transition

Critical minerals rose from almost nothing to one of the fastest-growing keywords across the tracked journals this year. Export controls on gallium, germanium, graphite and some rare earths since 2023 are natural experiments. Do they raise costs for clean-energy producers, speed up substitution and new supply, or both?

What prompted this

Across all journals, "critical minerals" had 9 papers in July–September 2026 against about 1 expected from its earlier share (see the trends page). Since October 2025 it appears on 14 papers, "rare earth elements" on 12 and "lithium" on 11, most of them in economics and finance journals.

Questions

After an export control is announced, how do prices outside the controlling country, and the share prices of the firms that use the mineral, respond?
Do controls speed up substitution (new materials and chemistries) and new mines elsewhere, and how fast?
Which clean-energy supply chains are most exposed, by product and country?

Data that could help

Export-control announcement dates, trade flows by product (UN Comtrade, China Customs), mineral prices, firms' supplier links, and patents on substitute materials.

Next step

Build a list of critical-mineral export controls since 2023 and run an event study of the share prices of firms that use the minerals.
