The Shortage No One Is Pricing In

Highlights

• Global dependence on China-controlled dysprosium and terbium refining threatens Western supply chains for electric vehicles, wind turbines, and defense systems despite available deposits.
• Demand for heavy rare earths will surge through 2035 driven by electrification and robotics, while supply remains geopolitically constrained creating a widening structural gap.
• Great Powers Era 2.0 transforms rare earth supply chains from background infrastructure into strategic power instruments as critical as oil once was.

The world thinks it has a rare earth problem. It doesn’t. It has a dysprosium and terbium problem—and almost no one is talking about it. These obscure heavy rare earth elements sit at the core of electric vehicles, wind turbines, and advanced defense systems. Yet as of 2026, nearly all of the world’s usable supply flows through China-controlled refining systems. The uncomfortable truth? The West isn’t short on deposits—it’s short on the ability to access, process, and scale the materials that actually matter.

A New Era of Power Is Taking Shape

Welcome to what Rare Earth Exchanges™ calls Great Powers Era 2.0—a world where supply chains are no longer background infrastructure, but instruments of power. Rare earth magnets and semiconductors are becoming as strategically important as oil and shipping lanes once were, not to mention those inputs linked to the semiconductor supply chains. The race is no longer about who has resources—it’s about who controls feedstock, refining, and production at scale. And today, the critical feedstock for heavy rare earths remains locked in Southeast Asia, flowing through systems the West does not control.  While Brazil and some sources in Africa and even America show promise, the timing of these assets is not in the couple of years category.

The Demand Shock Is Already Locked In

Between now and 2035, demand for dysprosium and terbium is set to surge—driven by electrification, defense, and the rise of robotics and advanced systems. Supply, meanwhile, remains constrained, fragmented, and geopolitically exposed. The result is a widening structural gap that won’t be solved by new mine announcements or pilot plants. This is not a typical commodity cycle—it’s a system-level constraint unfolding in real time.
