America gave up its rare earth edge. China took full advantage.

China’s dominance of rare earth processing creates a strategic supply-chain chokepoint that affects everything from consumer devices and data-center hardware to telecom, EVs, and defense systems. For CIOs and technology leaders, the key business risk is not just higher component costs, but potential shortages, delayed deployments, and reduced vendor flexibility if export controls tighten again after the current suspension window. IT organizations should treat rare earth dependency as a resilience issue, mapping exposure across hardware and supplier tiers and recognizing that rebuilding alternative sourcing will take years, not months.
