Fed Chair Kevin Warsh Warns AI Investors That Interest Rates Get in the Cracks

At an October 28 news conference following the Federal Reserve's decision to hold its benchmark rate steady at 3.75% to 4%, citing the need for more economic data amid still elevated inflation, Fed Chair Kevin Warsh pushed back on the idea that the AI investment boom sits outside the reach of monetary policy. "Interest rates get in the cracks," Warsh said. "Interest rates affect directly, or indirectly, almost everything."

Warsh argued that higher financing costs shape which AI projects get funded and how much capital they are able to raise, pointing to widening credit spreads as evidence that investors are growing more selective, favoring borrowers with credible paths to cash flow over those relying on optimistic assumptions about future returns.

He also noted that strong economic growth outside the tech sector is making inflation harder to bring under control, even as massive capital commitments to data centers and computing infrastructure remain exposed to execution risk if rates stay elevated.

The remarks carry implications for markets beyond AI stocks. Fewer expected rate increases could support Treasury prices in the near term, though Warsh suggested persistent inflation, resilient growth, and large fiscal deficits could still limit how far longer term yields are able to fall.
