Data center supply chain becomes next front in industrial policy debate

The Financial Times is pushing the data center buildout into the same frame that drove reshoring rhetoric in semiconductors: supply chain vulnerability as national security risk. The piece argues that the United States is at risk of ceding control over the physical infrastructure of AI to foreign suppliers, with specific attention to rare-earth elements and other critical minerals embedded in server racks, cooling systems, and power distribution equipment.

The comparison to rare earths is deliberate. China controls roughly 60 percent of global rare-earth mining and 85 percent of processing capacity, a position it built over two decades while the U.S. regulatory environment made domestic production uncompetitive. The argument is that data centers now present a similar choke point: if the hardware that powers large language models and inference engines depends on foreign supply chains, then compute sovereignty is an illusion.

The question is whether the analogy holds. Rare earths became a bottleneck because they require environmentally messy refining and China was willing to absorb the externality. Data centers require land, power, and capital, all of which the United States has in relative abundance. The vulnerability is not in the data center itself but in the components—transformers, batteries, chips, cooling systems—that are globally sourced. If the concern is supply chain resilience, the policy lever is procurement standards and tariffs on inputs, not subsidies for hyperscale construction.

The piece does not specify which components are at risk or which countries dominate supply. It also does not address the capital allocation problem: data center construction is already running ahead of utilization in some markets, and adding domestic content requirements raises costs in a sector where margins are compressing. The FT is correct that industrial policy is now the default frame for any infrastructure bottleneck. Whether data centers belong in that frame depends on whether the supply chain risk is actual or rhetorical.
