Core argument: A 30% disruption to U.S. neodymium supply drives a 2.2% GDP loss ($600bn), while China’s rare-earth exports total $3.4bn, creating.
Chinese rare earths offer a clear-cut case. In 2024, China earned approximately $3.4 billion from exporting rare-earth elements and magnets. Meanwhile, researchers at the U.S. Geological Survey estimate that a 30% disruption to the United States’ supply of the rare-earth element neodymium alone would reduce the country’s GDP by 2.2 percent—more than $600 billion. In other words, China would have to forgo no more than a couple of billion dollars in export revenue to inflict over half a trillion dollars of damage on the U.S. economy. This asymmetry is what gives Chinese export controls their power. It also highlights a broader reality about economic warfare. When they have a choice, states don’t weaponize interdependence—they weaponize dependence.How to Fight an Economic War
AI Summary. China earns ~$3.4bn annually from rare-earth exports, yet a 30% supply disruption of neodymium alone would reduce U.S. GDP by 2.2%, or $600bn+. This asymmetry means economic warfare is most powerful when one side holds a dependency the other cannot quickly replace.

Edward Fishman makes the case for deeper integration of Western economies in order to manage chokepoints; integration “can preserve the scale modern economies require while neutralizing the coercive power of rivals.”
