IEA warns China's rare earth export curbs risk $6.5 trillion in global downstream production

The International Energy Agency (IEA) has warned that full implementation of China's rare earth export restrictions could put an estimated $6.5 trillion in annual downstream production outside the country at risk, according to its Global Critical Minerals Outlook 2026 released on 16 July 2026 (IEA).

The report states that rare earth export controls introduced by China in April 2025 on seven heavy rare earth elements forced some automakers to reduce production or temporarily suspend operations. These controls were further expanded in October 2025 to cover additional materials and licensing requirements, including internationally made products containing Chinese-sourced rare earths or using Chinese technologies, though implementation was delayed for one year until November 2026 (IEA executive summary; Reuters).

If enacted fully, the measures could expose about $6.5 trillion of production across the automotive, high-tech, defence and energy sectors to supply disruptions, the IEA said. The United States and Europe would account for nearly half of the economic impact (Reuters). Rare earths, a group of 17 metals used in small quantities, are essential for electric vehicles, smartphones, aircraft, wind turbines and advanced defence systems.

The agency also flagged risks from China's planned export controls on graphite, a key material for electric vehicle batteries. Full disruption of battery-grade graphite trade could put over $300 billion per year of downstream production outside China at risk, with China accounting for more than 90% of global processed graphite output (IEA; Reuters).

IEA Executive Director Fatih Birol said: “Our latest analysis shows that vast amounts of economic value depend on relatively small volumes of critical minerals, whose supply chains remain highly concentrated and are therefore vulnerable.” The report notes that the recent expansion of export controls globally has transformed concerns around high supply concentration from a theoretical vulnerability into an immediate economic security challenge (IEA).

Supply concentration in refining has increased for most minerals. Over the past two years, the top refiners—Indonesia for nickel and China for other key energy minerals—accounted for over three-quarters of total growth in refined supply. Excluding rare earths, the average share of the top refining country rose to 72% in 2025 from 70% in 2023. Rare earth refining saw modest improvement, with China's share falling from over 90% in 2023 to 85% in 2025 due to new projects in the United States and production increases in Malaysia; it is projected to reach 70% by 2035 if planned projects proceed (IEA).

Critical mineral investment fell by 9% in 2025, ending several years of growth, amid price volatility and geopolitical tensions. Public finance commitments more than quadrupled between 2023 and 2025 to $65 billion. The report highlights a structural imbalance, with investment concentrated in mining while refining and downstream capacity lag; planned rare earth magnet production outside dominant suppliers amounts to just one-third of expected mine output by 2035 (IEA executive summary; Metal Tech News).

Prices of critical minerals rebounded in 2025 and early 2026 after prior declines, with base metals such as copper rising sharply and strategic minor minerals seeing significant gains amid export controls. The IEA recommends greater focus on emergency preparedness, including strategic stockpiles for high-risk materials at a modest net annual cost, alongside efforts to address technology, equipment and workforce gaps to build resilient supply chains (IEA).

Why this is uncovered

The IEA report received coverage from Reuters and specialist outlets in mining, metals and energy sectors, along with some financial sites, but saw limited pickup or deeper analysis in broader mainstream consumer media. Its technical focus on supply chain metrics and long-term projections likely kept it primarily in trade and industry reporting rather than general news cycles.
