A Fed governor just said AI data centers are part of the inflation problem. Here is her case.

A recap, not financial advice. I build apps and invest in index funds, I am not a financial advisor.

Most of the AI and money talk this year has been about stock prices. On Monday, a Federal Reserve governor talked about something closer to home: what building all this AI costs everyone else. Governor Lisa Cook gave the opening keynote at Oakland Tech Week, co-hosted by the Kapor Center, and spent a good part of it on how the AI build-out is feeding into inflation. (Federal Reserve)

The short version

• The money is mostly still coming. Cook said companies have announced about $2 trillion in data center plans, and "have only spent a small fraction" of it so far.
• It competes with everyone else. Her words: "Data-center investment relies on inputs, like construction labor and energy, that are broadly used in many sectors."
• Utility bills are already moving. She said electricity and water costs are each up around 5 percent over the past year, "potentially attributable in part to AI."
• The real worry is spillover. Even if prices in the narrow AI sector cool off, she warned, "new and more broadly based price pressures may take its place."

Why a data center can raise your electric bill

A software boom used to mean more people writing code. This one needs physical stuff: buildings, substations, transmission lines, cooling, and enormous amounts of power. The electricians, concrete crews, and utilities building a data center in one county are the same ones a hospital, a factory, or a housing project down the road is trying to hire.

When that much demand shows up at once, prices for those inputs go up, and those costs land in places that have nothing to do with AI. That is the difference Cook is pointing at. A price spike inside the AI industry is one thing. Higher costs for power and construction labor across the whole economy are harder for the Fed to wait out.

Where inflation stands

Cook put total inflation at an estimated 3.8 percent over the 12 months into August, which she called "almost double our target." She also confirmed she voted with the rest of the committee for the quarter point hike in September, the one I covered in the September 18 finance recap. (Federal Reserve)

Other outlets read the speech the same way: AI spending is now one of the things keeping inflation from getting back to 2 percent. (The Hill) (CFO Brew)

She is not anti-AI

This was not a doom speech. Cook called AI "the most significant technological shift of our lifetime" and said she expects it to bring "modest disinflation within the next few years" as productivity gains show up. Her catch is that higher productivity also raises wages and wealth, which raises demand, so the relief may be smaller than people hope.

She also cited a number worth noting: nearly half of small employer firms are using AI, and 71 percent of those report productivity gains, based on the Fed's Small Business Credit Survey. On jobs, she flagged early displacement in coding and simultaneous translation, and a harder market for recent graduates. Her hope is that AI spreads "at a pace and in a way that allows job creation to match or exceed job destruction." (Federal Reserve)

What it means for a boring index portfolio

• Rates may stay higher for longer. If AI building keeps power and labor costs up, the Fed has less room to cut. That keeps pressure on the 10 year yield I wrote about in Wednesday's post.
• The AI trade cuts both ways. Data center spending is great news for the companies selling chips and power gear, and VTI owns them. The same spending raises costs for a lot of other companies VTI also owns.
• Savers still win a little. Higher rates mean cash and bond funds like BND keep paying more than they did a few years ago.

My plan does not change on a speech. VTI, VXUS, and BND, steady contributions, and no guessing which AI stock wins. If you want to watch what your holdings actually pay you instead of the daily price, that is why I built Holdwise, my dividend tracker for buy and hold investors.

Bottom line: a Fed governor is now saying out loud that the AI build-out is part of the inflation story, not just a tech story. That does not mean sell anything. It means rates may stay up longer than the headlines about AI efficiency suggest.
