Fed's Cook Warns the AI Data Center Boom Is Broadening Inflation Beyond the Tech Sector

The AI boom is no longer just raising the price of chips. According to Federal Reserve Governor Lisa Cook, it is starting to show up in everyone's electricity bill.

Speaking at Oakland Tech Week on Sept. 28, Cook said AI-driven investment has been one of the factors keeping inflation above the Fed's 2 percent target over the past year. Coming from a sitting governor who just voted to raise rates, that is a pointed message.

From chips to concrete

The first-order effect is obvious. Prices for AI-related goods such as chips, computers, and software have surged as companies race to build capacity.

Cook argued that some of this is concentrated demand in one sector, the kind of thing central bankers usually look through. The problem is that data centers do not only consume GPUs. They pull on construction labor and on energy that the rest of the economy also uses, and that is how a sector boom turns into broader price pressure.

She pointed to electricity and water costs, each up around 5 percent over the past year, which she said may be partly attributable to AI. Core goods prices have been running at more than a 3 percent annual pace so far this year. And AI-linked stock gains have made households feel wealthier, feeding consumer spending.

Most of the spending has not happened yet

The number that should worry markets is this one: companies have spent only a small fraction of roughly $2 trillion in announced AI-related plans. If the pressure is already visible, the bulk of the buildout is still ahead.

Cook does expect AI to eventually lift productivity, which could ease inflation modestly. But she does not expect that to arrive in time to offset the broadening pressure later this year. On jobs, she said there is limited evidence of displacement so far, though she is watching coding, translation, and hiring of new graduates.

She is not the only Fed official sounding this alarm. Chicago Fed President Austan Goolsbee has raised similar concerns about data centers and prices.

A hawkish backdrop

Cook voted with the rest of the FOMC for a 25 basis point rate hike at the September meeting. She cited total inflation around 3.8 percent and core inflation around 3.4 percent over the 12 months to August, well above target.

Put together, her speech reads as a warning that the Fed cannot treat the AI boom as a tech story. As long as the data center buildout keeps pulling on power, water, and workers, it is part of the inflation problem the Fed is raising rates to fight.
