Fed Chair Kevin Warsh’s warning to AI investors: ‘Interest rates get in the cracks’

The Fed held its benchmark rate at 3.75%–4%, citing elevated inflation and the need for more economic data; Chair Kevin Warsh said interest rates still influence AI investment and which projects receive financing. Strong growth and broadening capital spending give policymakers room to remain patient but could sustain price pressures, while widening credit spreads point to greater investor selectivity. Marsh economist Julius Bendikas said Treasury yields may have room to fall as expectations for future hikes moderate, though strong growth, elevated energy prices and large fiscal deficits pose upside risks to yields.

Analysis

View: The key transmission is not whether AI capex stops, but who can fund it and who captures returns. Higher discount rates raise the hurdle for projects whose payoff depends on utilization, power availability, and future customer demand. Cash-generative platforms and suppliers with near-term orders should be more resilient than marginal, debt-funded infrastructure projects—but capex could remain high if strategic competition outweighs financing costs. In that case, spending may persist while returns on invested capital deteriorate.

Broadening investment outside tech is a second-order inflation risk: it can sustain demand and keep the Fed constrained even if AI spending cools. That argues against treating a softer policy path as an automatic, broad duration rally. Over the next 1–3 months, inflation data, Treasury issuance/auction demand, credit spreads, and company capex guidance are the key discriminators; over 6–18 months, project utilization and monetization matter more than announced spending. The contrarian risk is that markets focus on capex deceleration while underestimating productivity and cash-rich incumbents’ ability to keep investing. Conversely, headline capex growth can mask weaker project-level returns. Verify actual financing costs, contracted utilization, and realized customer revenue before assigning winners.

Key Decisions for Investors

• Conditional 1–3 month expression: consider a 2s10s Treasury curve steepener if inflation data ease while fiscal supply and term-premium concerns keep the long end supported. Invalidate if a growth shock drives 10-year yields down faster than front-end yields, or if inflation reaccelerates enough to lift expected policy rates.
• Do not buy AI exposure indiscriminately on capex announcements. Prefer cash-generative platforms and nearer-term revenue exposure over marginal projects reliant on external financing; make this a relative-value position only after checking leverage, contracted utilization, and returns on invested capital.
• Watch for a credit-market confirmation trade: if spreads continue to widen for leveraged data-center or AI-infrastructure borrowers while investment-grade technology credit remains resilient, consider shorting the former against the latter. The article gives no spread levels or issuer exposures, so verify the divergence and use defined risk before positioning.
• Reassess after the next inflation releases, Treasury auctions, and earnings guidance on capex and utilization. A sustained widening in funding spreads or weaker project returns would strengthen the selective-credit thesis; stable financing and evidence of monetization would falsify it.
