When people talk about semiconductor supply chains, they talk about TSMC, ASML, and Nvidia. They rarely talk about helium — which is a significant oversight, because without helium, none of those advanced fabs work.
Helium is used in semiconductor manufacturing as a coolant and purge gas. Its extremely low boiling point makes it irreplaceable for maintaining the cryogenic temperatures required in certain fabrication steps. There is no substitute at current technology levels. When you run out of helium, the fab stops.
Global helium supply is heavily concentrated — the U.S., Qatar, Russia, and Algeria account for the vast majority of production. Russia’s Gazprom operates one of the world’s largest helium facilities in eastern Siberia. Sanctions, supply disruptions, or deliberate restriction could tighten an already constrained market with very little warning.
Craig Tindale’s broader argument applies here with full force. The material dependencies of the technology economy run far deeper than the technology economy acknowledges. We have built an extraordinarily complex industrial system and then systematically dismantled our understanding of what holds it together. Helium is one of those invisible load-bearing walls. It doesn’t appear in most supply chain risk assessments because it doesn’t fit neatly into the categories that analysts use.
The same pattern repeats across dozens of industrial gases and process inputs: chlorine, ammonia, sulfuric acid, argon. Each one is essential to some critical production process. Each one is either supply-constrained, geographically concentrated, or both. The lesson from helium is the same as from copper, gallium, and tantalum: the modern economy’s vulnerabilities are not financial. They are physical. And physical constraints don’t respond to monetary policy.
