G7 Finalizes $1.2B Critical Minerals Reserve

G7 nations endorse a $1.2B critical minerals strategic reserve targeting antimony, gallium supply, and rare earth elements to reduce allied dependence on Chinese supply chains ahead of a November 2026 export ban deadline.

Lead

Group of Seven nations, meeting at the G7 Leaders' Summit in Évian-les-Bains, France on June 17, 2026, formalized a $1.2 billion allied Critical Minerals Strategic Reserve that places antimony, gallium, and rare earth elements at the center of allied supply chain defense for the first time. Australian Treasurer Jim Chalmers presented the initiative to G7-plus finance ministers assembled by U.S. Treasury Secretary Scott Bessent, framing it as a mechanism to "shore up access to critical minerals during periods of market disruption." Resources Minister Madeleine King confirmed the reserve will be fully operational before the close of 2026 — a timeline calibrated to China's looming November deadline on suspended export controls.

What Happened

The reserve's architecture deploys AU$1 billion drawn from an expanded AU$5 billion Critical Minerals Facility in government-backed loans and equity support, alongside AU$185 million earmarked for targeted stockpile implementation. Its operational mechanism centers on offtake agreements — pre-committed purchase contracts backed by export finance credits — allowing Australia to build holdings that can be channeled to allied partners facing acute supply emergencies.

The selection of antimony, gallium, and rare earth elements as initial reserve priorities reflects a precise mapping of recent supply chain fractures. Australia's position as a producer or emerging processor in each category makes it a natural anchor for the allied effort, providing the G7 with a source of material outside China's processing dominance that can be drawn upon during episodes of deliberate supply disruption.

China's Export Control Leverage

Beijing's progressive tightening of export controls provides the backdrop. In August 2024, China introduced antimony restrictions that caused Chinese export volumes to collapse by roughly 97 percent, driving global prices approximately 200 percent higher within months. A December 2024 directive extended prohibitions on gallium, germanium, and antimony exports to the United States. In April 2025, seven medium and heavy rare earth elements — including terbium, dysprosium, and samarium, which are essential to permanent magnets in precision-guided munitions, EV drivetrains, and wind turbines — were added to the control list. An October 2025 omnibus measure went further, requiring export licenses for any foreign-made product containing 0.1 percent or more Chinese-origin rare earth content.

The practical consequences were severe. European defense contractors reported shortages of neodymium magnets for precision-guided munitions, while EV manufacturers absorbed estimated material cost increases of $500 per vehicle. Export license approval rates for European industrial buyers fell below 25 percent.

China issued a one-year suspension of the prohibitions in November 2025 following high-level diplomatic engagement — but the suspension is framed internally as a tactical pause and expires in November 2026, compressing the window for allied reserve buildup.

The G7 Coordination Architecture

The $1.2 billion reserve is one instrument within a broader framework the G7 finalized at Évian. The Leaders' Declaration on Securing Supply Chains for Critical Minerals established the Critical Minerals Resilience and Production Alliance and set a binding target: reduce dependence on any single non-G7 supplier of rare earths and permanent magnets to below 60 percent by 2030, with an ambition of reaching 50 percent as quickly as market conditions permit.

A new coordination platform led by the International Energy Agency will monitor mineral markets in real time, issue early supply-risk warnings, and support G7 policy decisions. Lithium and nickel are the two pilot commodities for collective stockpiling, with five additional minerals to be integrated into the framework annually.

The investment mobilization behind the alliance is substantial. G7 members and partner nations have announced 195 critical minerals projects since the start of 2026, attracting €64 billion (approximately $74 billion) in committed capital across equity stakes, offtake agreements, and development finance. The United States separately launched Project Vault, a $12 billion domestic critical minerals program, with its first funding tranche closing in April 2026.

Geopolitical Dimension

The G7 declaration draws an explicit line between rare earth elements G7 supply dependency and national security, citing "grave concerns" over the use of non-market policies and "arbitrary export restrictions" as instruments of economic coercion. The framing marks a doctrinal shift: global supply chain security for critical minerals is now treated as a strategic deterrence asset rather than an industrial policy question — a logic analogous to the strategic petroleum reserve system built after the 1973 oil shock.

China's position remains structurally dominant. Beijing accounted for 69.2 percent of global rare earth production in 2025 — 270,000 of 390,000 tonnes produced worldwide — while controlling an estimated 91 percent of rare earth separation and refining capacity and 94 percent of rare earth permanent magnet output. In antimony, China holds approximately 60 percent of global reserves; in gallium, China's smelting capacity dwarfs all allied sources combined.

Outlook

The $1.2 billion reserve represents the G7's first allied instrument specifically designed to stockpile and deploy antimony, gallium, and rare earth elements to partners during supply emergencies. Reaching operational status before November 2026 would position allied governments to draw on initial holdings at precisely the moment China's export ban suspension expires. Whether the broader G7 architecture — the IEA platform, the €64 billion project pipeline, and the 2030 dependency-reduction targets — can shift market structure at sufficient scale to offset China's processing dominance remains the central, unanswered question. The next benchmark arrives when G7 ministers are expected to finalize specific dependency-reduction targets for lithium, cobalt, and graphite before year-end.
