IEA Warns $750 Billion Investment Needed in Critical Minerals Mining and Refining by 2040 to Close Supply Gaps

The Quick Take

• The IEA projects critical mineral demand will surge significantly through 2040, with supply gaps persisting under current investment levels.
• The Stated Policies Scenario requires more than $750 billion in mining and refining investment between now and 2040.
• Lithium, cobalt, nickel, and copper face the most acute supply-demand mismatches given accelerating EV and grid storage demand.
• The IEA warns that current project pipelines are insufficient to meet demand, creating long-term price support for miners.

The International Energy Agency's latest critical minerals assessment delivers a stark message: the energy transition's raw material requirements are structurally outpacing investment in mining and refining capacity. Under the IEA's Stated Policies Scenario — which models current government commitments, not aspirational targets — the world needs more than $750 billion in mining and refining investment through 2040. The gap is largest for materials central to battery technology: lithium, cobalt, nickel, manganese, and graphite.

The supply concern is not hypothetical. Lithium carbonate prices have already experienced dramatic boom-bust cycles as supply additions failed to anticipate the pace of EV adoption. The IEA's analysis suggests this volatility is structural rather than cyclical: mine development timelines of 10-16 years mean that decisions made today determine supply availability in the late 2030s, when EV penetration in major markets is projected to reach critical mass. The refining bottleneck — particularly for lithium and cobalt, where Chinese processors dominate — adds a geopolitical dimension beyond simple supply economics.

For investors, the IEA's $750 billion figure provides a macro anchor for the critical minerals investment cycle. Mining companies with shovel-ready assets in lithium, nickel, and copper — particularly those outside China's processing dominance — are positioned to attract infrastructure fund and sovereign wealth capital seeking energy transition exposure. Watch for the IEA's annual critical minerals roadmap update in the fall and government procurement announcements from the US, EU, and Japan as they operationalize their mineral security strategies.
