Fed Sept 16 Decision: 25bp Hike Would Be First Since 2023

A quarter-point increase on Wednesday would put the federal funds target range at 3.75%-4.00%, up from the 3.50%-3.75% the Federal Open Market Committee voted to keep at its July meeting. The decision lands at 2 p.m. Eastern on September 16, and as of the meeting's first day nothing has been announced: what exists is futures pricing, one hawkish speech from the chair, and inflation data that points in two directions at once.

What the Fed itself has put on the record

The Federal Reserve's published meeting calendar sets the September session for Tuesday, September 15 and Wednesday, September 16, with the policy statement released at 2 p.m. Eastern on the second day and a press conference by the chair afterward. This is one of the four meetings a year that also carries a Summary of Economic Projections and the accompanying dot plot. As the Yahoo Finance live blog notes, the plot carries up to 19 dots, one per participant, and is anonymous.

The most recent official account is the minutes of the July 28-29 meeting, published by the Fed. According to those minutes, nine members agreed to maintain the target range at 3-1/2 to 3-3/4 percent and reaffirmed the policy of keeping ample reserves in the banking system. The same document records what markets were pricing at the time: investors expected no action in July as a base case but put roughly a one-in-three chance on an increase, and at longer horizons were fully pricing a 25 basis point hike by the September meeting. The minutes also note nominal Treasury yields rose 25 to 30 basis points, driven by higher real rates.

The move in expectations came on August 28, when Chair Kevin Warsh delivered his keynote at the Jackson Hole Economic Policy Symposium, the text of which the Fed has published. CNBC reported him saying that while the summer's inflation readings were better than expected, they "do not tell me that underlying trends have meaningfully improved," and that he recommitted to the 2% PCE goal as a "firm, fixed target." Two accounts of the same speech differ in emphasis rather than fact: The Washington Post reported Warsh said he was "impressed" with the economy's strength but "stopped well short of clearly signaling an interest-rate increase" at the next meeting, while CNBC's analysis framed the speech as more hawkish than his tone after the July meeting. Both are consistent with a chair who described inflation as the priority without committing to a September action.

How likely is a hike, and what the odds actually measure

Reported probabilities have moved and they differ by platform. CNBC reported on August 28 that fed funds futures implied a nearly 56% chance of a quarter-point hike in September, with prediction market Kalshi at 48%, and that before Warsh's speech the odds of no change had been close to 70%. A Yahoo Finance report roughly a week before the meeting put CME FedWatch above 60%, Kalshi at 57% and Polymarket at 49%. Forbes reported a 66% FedWatch reading on August 31.

These are not contradictions. They are different instruments read on different dates: FedWatch derives probabilities from 30-day fed funds futures prices, while Kalshi and Polymarket are event-contract markets with their own liquidity and fee structures. All of them are dated, model-based estimates of what traders will pay, not statements by the Federal Reserve about what it will do. The honest summary is that since Jackson Hole the market has priced a hike as more likely than not, in a range from roughly half to two-thirds, and that pricing can change again before 2 p.m. Wednesday.

Three inflation gauges, three different answers

The July data released by the Bureau of Economic Analysis on August 26 is the last full PCE reading before the decision. CNBC reported the PCE price index rose a seasonally adjusted 0.2% for the month, putting the 12-month rate at 3.7%, both 0.1 percentage point above the Dow Jones consensus, while core PCE excluding food and energy rose 0.2% on the month and 3.3% over 12 months, in line with forecasts. Separately, the Dallas Fed's trimmed mean PCE, which discards the most extreme price movers each month, was 2.3% over the 12 months through July.

Those three numbers are directly comparable in one respect only: all are 12-month changes through July 2026. What they cover is different. Headline PCE includes food and energy and therefore absorbs the energy prices that several accounts of this cycle point to; core strips both categories out entirely; trimmed mean removes whichever categories moved most in each month regardless of what they are. That is why a reader can see 3.7% and 2.3% in the same release month without either being wrong, and it is the concrete version of the argument Warsh made about "underlying" inflation. Do not mix bases: a 0.2% monthly change annualizes to roughly 2.4%, which is not the same statistic as the 3.3% twelve-month core rate and should not be set against it.

For borrowers, a 25 basis point increase in the target range applies to an overnight rate at which banks lend reserves to each other. It passes through fastest to products priced directly off short-term benchmarks. It does not mechanically set 30-year mortgage rates, which track longer-dated yields; the 25 to 30 basis point rise in nominal Treasury yields recorded in the July minutes is a separate observation about the long end, not a policy-rate effect.

What remains unknown before Wednesday afternoon

Three things the available evidence does not settle. First, the vote: the July minutes record nine members supporting a hold, which tells you nothing about the September tally or whether there will be dissents. Second, whether any hike would be a single move or the start of a sequence; Warsh, per CNBC, declined to offer forward guidance or a reaction function. Third, the projections themselves, since the dot plot released Wednesday is the first read on where participants now see rates ending 2026 and 2027.

Dated items on the calendar: the statement and dot plot at 2 p.m. Eastern on September 16, followed by the chair's press conference; the Dallas Fed's next trimmed mean update on September 30, alongside the BEA's August personal income and outlays data; and the FOMC's remaining 2026 meetings on October 27-28 and December 8-9, per the Fed's published schedule.
