The answer, in one paragraph

Markets anticipated the September increase because the July meeting had three regional presidents favoring a hike, and Kevin Warsh subsequently said inflation was too high and that the Fed might have work to do. August payrolls rose 162,000 and lifted hike odds to 60 percent, producer prices rose 0.4 percent in August, and consumer prices also rose 0.4 percent after a 0.1 percent July increase. By September 11, investors put the probability of an increase at 85 percent. The FOMC then unanimously raised its target range to 3.75 percent to 4.00 percent on September 16.

The argument runs in 3 strands, in the order the answer makes them, not by date; inside a strand the steps run forward in time. Each step is a dated entry with its source.

The hawkish shift

1Three hike dissentsJul 29, 2026Announcement
Fifth straight hold; three regional presidents dissent in favour of a rate increase
The FOMC voted 9 to 3 to keep the range at 3.5 to 3.75 percent, with Hammack, Kashkari and Logan preferring a quarter-point increase, the first dissents for a hike since 2019 and a sign the debate under Warsh had flipped from when to cut to whether to tighten. Inflation remained elevated relative to target and core PCE was running near 3.3 percent.
Federal Reserve Board · Voting against the monetary policy action were Beth M. Hammack, Neel Kashkari, and Lorie K. Logan, who preferred to raise the target range for the federal funds rate by 1/4 percentage point at this meeting.
Why it matters here. The dissents for a quarter-point increase were followed by Warsh’s Jackson Hole warning that inflation was too high and the Fed might have work to do.

2Warsh warns on inflationAug 28, 2026Announcement
Jackson Hole: Warsh says inflation is too high and the Fed may have work to do
In his first Jackson Hole keynote, on his hundredth day as chair, Warsh declined to offer forward guidance or a reaction function, said this summer's better inflation readings did not show underlying trends had meaningfully improved, and set his standard as confidence that inflation is moving to target clearly and at sufficient speed. He also argued AI investment could lift growth substantially. Two-year yields jumped and futures moved to better than even odds of a September hike.
Federal Reserve Board · Here is my standard: We must be confident that underlying inflation is moving to our objective, clearly and at sufficient speed. Otherwise, we have work to do.
Why it matters here. Warsh’s inflation warning was followed by an August payroll report strong enough to push traders’ hike odds above even.
