Fed's Paulson says "modest further tightening" may be needed, and blames part of it on AI

Philadelphia Federal Reserve President Anna Paulson said on Thursday that the Fed may need to raise interest rates again. "Looking ahead, if conditions evolve as I expect, some modest further tightening may be warranted," she said in prepared remarks opening the bank's 10th Annual Fintech Conference.

Paulson said she supported last week's quarter-point increase, which took the federal funds target range to 3.75%-4%, and called returning inflation to 2% "non-negotiable." CNBC reported that New York Fed President John Williams said earlier in the day it was "reasonable" to expect another hike before year-end, and that CME FedWatch put the odds of an October hike at 64%.

The number behind the number

The headlines will focus on the hike signal. The more useful part of the speech is why she thinks inflation is stuck, because it is not the reason most people assume.

Paulson said underlying inflation, meaning inflation with temporary shocks such as oil swings and tariff price increases stripped out, is running at about 2.5% to 3%, and "that gap has shown little sign of closing." She said inflation has stayed high "only in part" because of tariffs and energy. She named a third driver: the artificial intelligence buildout.

Her evidence was specific. Import prices for computers and computer accessories are up 24% over the last 12 months, she said, and one technology company told the Philadelphia Fed that price pressure from AI spending is running through the whole electronics supply chain, "from circuit boards to capacitors." Her summary: "While the impact of AI on productivity remains unclear, its effect on prices is not."

This matters for how long rates stay high. Oil can fall and tariffs can be rolled back. Data center spending is a multi-year capital program, and Paulson is saying it is adding to demand for chips and construction materials right now. If the Fed treats that as a lasting source of inflation, it has less reason to look through it.

She also said labor is not the problem. Unemployment is 4.1%, which she considers consistent with maximum employment, job gains averaged 74,000 a month over the summer, and "employers report few pressures to raise wages."

Who it hits

Most business credit lines float off the prime rate, which moved to 7% after last week's hike, as we covered in what the hike means for a contractor's floating-rate line. Every further quarter-point move adds $625 a year in interest on $250,000 of borrowing.

The market is already pricing more than one. CNBC reported that fed funds futures imply a rate of 4.8% by the end of 2027. The effective fed funds rate is 3.88% today. If prime tracks that full move of about 0.92 of a point, the same $250,000 balance costs about $2,300 a year more than it does now.

The AI point lands on a second group: any small firm that buys computers, servers or electronic parts. A 24% rise in import prices is a cost that does not show up in the Fed's rate decision but does show up on the invoice.

What traders watch next

The bond market has moved ahead of the Fed. On Treasury's own curve, the 2-year yield closed Wednesday at 4.85%, the 10-year at 5.11% and the 30-year at 5.40%. The next big inputs on the calendar are the September jobs report on Oct. 2 and September CPI on Oct. 14. Track the moves on our 10-year Treasury chart and the markets board.
