Is the Fed About to Raise Rates for the First Time Since 2023?

Fed Chair Kevin Warsh delivers his first interest rate decision today, and an AI story is arguably driving Fed policy as much as inflation is.

What's Happening Today

The Federal Reserve's two-day meeting wraps today, September 16, 2026, with the rate decision landing at 2:00 PM ET and Warsh's press conference at 2:30 PM ET. The current target range is 3.50%-3.75%. Markets are pricing in close to 87% odds of a quarter-point hike to 3.75%-4.00%, the first increase since 2023. Several major banks reversed earlier "hold" predictions after Warsh's hawkish Jackson Hole speech and a hotter-than-expected August inflation reading.

Why AI Spending Is Tangled Up in This

Trillions in AI data center and chip spending have helped drive real growth, but growth adds inflationary pressure, exactly what a hike is meant to cool. The 30-year Treasury yield hit a 19-year high above 5.3% this month, and the 10-year yield also pushed past levels last seen in 2007. That pressure already reached homebuyers: the 30-year fixed mortgage rate hit 6.76% as of September 10, up from 6.16% in January, adding roughly $250 to $400 a month to a typical home purchase.

The Industry Is Nervous Too

Just days before this decision, Anthropic, OpenAI, and Microsoft publicly backed slowing AI development. Anthropic CEO Dario Amodei published an essay called "We Must Pace the Frontier," warning AI systems could become capable of "taking over the entire internet" within 6 to 12 months without outside checks. Nvidia's Jensen Huang called extinction fears "made up," and President Trump called AI safety warnings a "hoax" the same week.

That same weekend, the Philadelphia Semiconductor Index dropped 5.9% on Monday, its steepest fall since March, with Nvidia down 3.4%, Intel down 5.6%, and Micron down about 7%.

What This Means for Businesses

Whatever the Fed announces today, the transmission chain is already moving: Fed policy affects Treasury yields, which affect the risk-free rate assumptions baked into venture funding models, which affect what investors will pay for late-stage AI startup rounds.

A few things worth doing regardless of today's outcome:

• Revisit AI infrastructure budgets against a higher-for-longer rate environment

• If growth plans depend on a funding round in the next two quarters, model a tighter valuation environment now
