Artificial intelligence may be driving headlines, but one of its biggest vulnerabilities is an obscure metal that few people have ever heard of. Yttrium, a rare earth element first identified more than two centuries ago, has quietly become an essential ingredient in advanced semiconductor manufacturing, according to the Financial Times. As demand for AI chips accelerates, securing reliable access to the metal has become a growing strategic concern.
"We're in the middle of a sea change in terms of how the global economy works."
— Daniel Yergin, vice-chair of S&P Global, describing the shift away from purely efficiency-driven global supply chains.
That concern stems from a simple reality: China dominates the processing and supply of yttrium, along with many other niche metals that modern industries depend on. Over the past several years, Beijing has tightened export restrictions on a number of critical minerals, giving it increasing leverage over global supply chains at a time when geopolitical tensions with the United States remain elevated.
FT writes that while gallium and germanium have received much of the public attention because of their roles in defense systems and electronics, industry executives increasingly argue that yttrium may represent the bigger long-term problem. One semiconductor supplier called it "the killer chokepoint," warning that the industry faces "an existential risk" until alternative supply chains are fully established.
