Warsh Says Higher Rates Are Reaching the AI Investment Boom

Fed Chairman Kevin Warsh said higher interest rates are reaching the investment surge and that economic growth is broadening beyond it, according to a Wall Street Journal report published October 29, 2026. The comments follow a Federal Open Market Committee (FOMC) meeting on October 27 and 28. The FOMC is the group that sets the Fed's main interest rate target. Reuters had reported before that meeting that the Fed was expected to keep its federal funds target range at 3.75% to 4.00%. That range is the band the Fed sets for overnight lending between banks, and it feeds into borrowing costs for credit cards, auto loans, and adjustable-rate mortgages.

The policy backdrop is a pause. Reuters reported on October 26 that the Fed had paused rate hikes, a decision that came less than a week before the November 3 elections.

In its semiannual Monetary Policy Report testimony on July 14, the Fed said equipment investment overall rose about 8 percent over the year ending in the first quarter. Equipment investment is spending by businesses on machines, tools, and computers. At the July 29 press conference, Warsh's transcript cited four-quarter growth of nearly 20 percent in the AI-related category of high-tech equipment and software. The July Monetary Policy Report stated that economic headwinds were partially offset by the surge in AI-related investment.

Warsh's position, as he has argued it, is that an AI boom will raise productivity, meaning output per worker, without reigniting inflation, the steady rise in prices across the economy. The Journal reported on August 30 that he reaffirmed the Fed's 2 percent inflation target and argued that AI would drive prices down and allow the Fed to cut faster. Other officials have been less persuaded. Fed officials have flagged inflation running above 2 percent as a reason to doubt the productivity argument, and at Warsh's first meeting as chairman, more officials pointed to the AI build-out as a source of persistent inflationary pressure.

Chicago Fed President Austan Goolsbee has taken the opposing view. He argues that an AI boom everyone sees coming pulls demand forward, and that this requires higher interest rates.

The broader context here is that the disagreement is less about whether AI spending is real than about its timing and its effect on demand. If the spending raises productivity, supply grows alongside demand, and the Fed can tolerate lower rates for a given inflation path. If the spending arrives early and pulls demand forward, the same investment looks inflationary. Warsh's October remarks suggest he believes tighter policy is already working through the investment side of the economy, and that growth is spreading to other sectors. That is a claim about how policy transmits through the economy, and the next few quarters of capital spending and inflation data are the best place to test it.

In my view, the gap between the two growth figures matters too. A broad equipment increase of about 8 percent sits alongside an AI-linked slice growing close to 20 percent. Strong growth concentrated in one category can cut both ways. It can lift productivity in the sectors that adopt the technology, but it can also push up demand for scarce chips, power, and skilled labor faster than the rest of the economy can absorb it. Whether that pressure stays in one corner or spreads is the question that divides the committee.

For savers and borrowers, the practical question is the rate path, meaning where rates head next. Deposit yields, the return a bank pays on savings, and loan costs stay elevated for longer if the Fed holds rates high to cool an investment boom. If the Fed concludes that productivity is doing the work of disinflation, it could cut sooner. The Fed's own officials are split on which scenario is more likely, and the pause, coming days before the November 3 elections, puts the next decision under close public attention.

In my view, both sides are making forecasts about a technology whose productivity payoff is still being measured. Warsh's case rests on AI pushing prices down, Goolsbee's on AI pushing demand up, and the Fed's next decisions will show which effect dominates in practice.
