Fed Governor Cook warns AI investment risks broadening inflation
Federal Reserve Governor Lisa Cook said artificial intelligence investment is adding to inflation that has run above the Fed’s target for five straight years, and that broader price pressure tied to AI may not ease before year end. Cook laid out the analysis in a speech Monday, September 28, 2026, at the Oakland Tech Week Opening Keynote in Oakland, California, an event cohosted by the Kapor Center.
- Cook said companies have spent only a small fraction of $2 trillion in announced AI investment plans
- Electricity and water costs are each up about 5 percent over the past year, core goods prices over 3 percent
- Watch whether AI-linked price pressure broadens further in coming inflation data before year end
- $2T announced AI investment, only a small fraction spent
- 5% rise in electricity and water costs over past year
- 3%+ core goods price pace versus pre-pandemic decline
- 71% of AI-using small firms reporting productivity gains
Federal Reserve Governor Lisa Cook told the audience that AI-related price pressure is spreading beyond the technology sector itself and into inputs used across the economy. In the speech, titled “An Update on AI and the Economy,” Cook said inflation has stayed above the Fed’s 2 percent target for the past five years and that AI-driven investment has been a factor over the past year, with prices for AI-related chips, computers and software surging.
Cook says data-center buildout is bleeding into broader inflation
Cook said data-center investment relies on construction labor and energy that are used broadly across the economy, which could push prices up in sectors well outside AI itself. She cited electricity and water costs each up about 5 percent over the past year and core goods prices running above a 3 percent annual pace, both trends she linked in part to AI-related demand and to equity gains from AI enthusiasm feeding into household spending.
She said even more capital is queued up behind what has already been deployed. Cook noted that “companies have only spent a small fraction of the $2 trillion in announced plans,” and separately said “I do not expect those effects to arrive in time to offset the broadening inflationary pressure later this year,” referring to any disinflationary boost from AI-driven productivity gains.
Cook rules out using rate policy to chase sector-specific prices
Cook said narrowly concentrated price surges in AI-related goods should resolve on their own as supply chains adjust, without a monetary policy response.
“Our tools are too blunt to target narrow sectors, and addressing relative price shifts is not our role.”

She distinguished that narrow effect from the broader, economy-wide pressure she said AI investment and related wealth effects are now generating, which she said falls squarely within the Fed’s purview.
Labor market has held steady, but coding, translation and entry-level jobs show strain
Cook said the unemployment rate and layoffs have remained low and relatively flat over the past two years even as AI adoption has accelerated. She said there is evidence AI may be reducing labor demand in coding jobs in software and in simultaneous translation, and that recent college graduates are facing more difficulty finding first jobs, which she said is possibly linked to AI absorbing entry-level tasks.
She flagged a scenario in which AI produces a temporary rise in unemployment driven by a mismatch between workers’ skills and available jobs rather than a shortfall in demand. In that case, she said the Fed would have limited tools, since cutting the federal funds rate to address unemployment in that scenario could risk fueling inflation instead.
Small firms outpacing the large-company narrative, survey shows
Cook pointed to the Federal Reserve’s Small Business Credit Survey, released earlier this year, which found nearly half of small employer firms are using AI and 71 percent of those report increased productivity as a result. She said AI tools have made it cheaper and easier to start businesses, which she linked to a recent boom in new business formation, and said this challenges the assumption that only large, resource-rich firms can deploy AI effectively.
The BlockWest read. Cook is telling markets the Fed will not lean against AI capex inflation with rate hikes, which keeps financing conditions for data-center and GPU buildouts unchanged for now even as electricity costs and core goods prices climb. For allocators and banks underwriting AI infrastructure debt, the signal is that a supply-mismatch labor scenario, not sector-specific price spikes, is the risk that would actually move policy.
Cook did not say whether other FOMC members share her read on AI-driven inflation or how it will factor into the committee’s next rate decision, leaving that assessment for upcoming inflation and employment data to answer.
