China’s Looming Rare Earth Bans Put $6.5 Trillion in Global Tech at Risk

Global industrial manufacturing outside of China faces a substantial threat, with an estimated $6.5 trillion in downstream economic output at risk if Beijing fully implements its proposed rare earth export restrictions. According to the International Energy Agency (IEA) in its Global Critical Minerals Outlook report, these impending regulations could severely disrupt critical global supply chains. Although China initially announced these expanded export controls and licensing mandates in October of the previous year, it subsequently agreed to a twelve-month postponement. The prospective activation of these measures now threatens key international industries.

Rare earths consist of seventeen specialized metallic elements that, despite being utilized in minor quantities, remain indispensable for manufacturing high-tech electronics, commercial aircraft, automotive vehicles, and national defense systems. The IEA warns that a full enforcement of these restrictions would directly expose the global automotive, clean energy, technology, and aerospace sectors to severe material shortages. Geographically, Western economies will bear the brunt of this disruption, with the United States and Europe combined accounting for approximately half of the projected $6.5 trillion economic vulnerability. Fatih Birol, the Executive Director of the IEA, emphasized that massive segments of global economic value remain dangerously dependent on highly concentrated supply chains for these essential minerals.

In addition to rare earth metals, the report highlights comparable risks associated with China's intended export limits on graphite, a foundational component in electric vehicle battery manufacturing. Initially introduced alongside the rare earth restrictions and similarly delayed, the full implementation of graphite controls could imperil roughly $300 billion in downstream manufacturing outside of China. This vulnerability is compounded by the fact that China currently commands over 90 percent of the global processing capacity for graphite, leaving international battery manufacturers with few immediate alternatives.

In response to these vulnerabilities, Western governments have accelerated efforts to establish independent, resilient supply chains for critical minerals. Public funding allocated to these initiatives has surged dramatically, with state-backed financial commitments more than quadrupling between 2023 and 2025 to reach a total of $65 billion. These investments are already beginning to yield results. Thanks to newly operational refining facilities in the United States and Malaysia, China's share of the global rare earth market declined from 90 percent in 2023 to 85 percent in the subsequent year. If current and planned processing projects proceed according to their established timelines, the IEA projects that China's share of global supply could decrease further to approximately 70 percent by the year 2035, gradually mitigating the geopolitical leverage associated with these critical resources.
