IEA: China's Rare Earth Export Curbs Could Put $6.5 Trillion of Global Production at Risk

Since Beijing rolled out expanded export controls on rare earths in October 2025, suspended a month later until November 2026, the question has always been what happens if China stops delaying and actually flips the switch. The International Energy Agency answered that Thursday, July 16, with a number big enough to make anyone in manufacturing sit up: $6.5 trillion.

That's how much downstream global production the IEA says could be exposed to supply disruptions if China fully implements its rare earth export restrictions, according to the agency's Global Critical Minerals Outlook report. The automotive, high-tech, defence and energy sectors carry the most exposure. The U.S. and Europe together would eat nearly half of that economic impact, the IEA said.

The restrictions in question cover seven heavy rare-earth elements, first targeted by China in April 2025, then expanded in October to cover internationally made products containing rare earths sourced from China. Those expanded measures were suspended for a year, until November 2026, but the IEA says vulnerabilities remain regardless.

Small volumes, massive leverage

IEA Executive Director Fatih Birol put it plainly: "Vast amounts of economic value depend on relatively small volumes of critical minerals, whose supply chains remain highly concentrated and are therefore vulnerable," he said, according to Reuters reporting carried by WMBD Radio and separately by The National News.

Rare earths are a group of 17 metals used in small quantities per unit, a few grams here, a few ounces there. But without them, an F-35 doesn't fly and an EV motor doesn't spin. China remains the world's largest producer of rare earths, and its dominance runs through refining and processing, not just raw ore extraction.

The IEA also flagged a second front: graphite. China announced export controls on graphite at the same time as the rare earth curbs, later postponed those too, but if those take full effect, the agency estimates $300 billion of downstream production outside China would be at risk. China controls more than 90% of global processed graphite output, which matters enormously for EV battery manufacturing.

The Hormuz wildcard

OilPrice.com's coverage adds a detail the other two sources treat more lightly: the closure of the Strait of Hormuz disrupted supplies of aluminium, sulphur and helium, which in turn prompted China to curb sulphuric acid exports, creating ripple effects through mineral and fertilizer supply chains. That's a reminder these mineral chokepoints don't operate in isolation. A Middle East shipping crisis and a Beijing export policy can compound each other in ways that hit fertilizer prices on a farm in Iowa just as easily as a magnet factory in Germany.

Investment in critical minerals actually fell 9% in 2025, according to the IEA, ending a multi-year run of growth. Price volatility and geopolitical tension are the reasons cited. That's a genuinely bad signal if the goal is to build alternative supply chains fast. You can't out-invest a monopoly if investors are pulling back.

Where things are actually improving, slowly

China's dominance is not static, it's eroding, just gradually. New rare earth refining projects in the U.S. and Malaysia pulled China's share of the global rare earth market down to 85% last year from 90% in 2023, according to the IEA. Public financing commitments for new critical mineral projects more than quadrupled between 2023 and 2025, hitting $65 billion.

If planned projects stay on schedule, the IEA projects China's share could fall to 70% by 2035. That's real progress. But 2035 is nine years away, and "if planned projects proceed on schedule" carries significant weight. Government-backed mining and refining projects blow through timelines constantly, whether it's permitting delays in Nevada or financing gaps in Malaysia.

The suspension of both the rare earth and graphite export expansions runs through November 2026. That's four months from now. Whether Beijing extends the suspension again, lets it lapse, or moves forward depends on the state of U.S.-China trade negotiations at the time, none of which the IEA's report addresses. The $6.5 trillion figure is a risk exposure calculation, not a prediction. Whether it becomes a real economic event depends entirely on decisions in Beijing that nobody outside the Chinese government can currently forecast with confidence.
