**Persistent inflation pressures and the Federal Open Market Committee’s hawkish September projections are the main drivers behind the 74.5% market-implied probability of a 25 basis point federal funds rate increase at the December 2026 meeting.** The Fed raised its target range to 3.75–4.00% in September, with 16 of 18 participants projecting at least one additional hike by year-end in the dot plot. Recent official comments, including from Governor Waller, emphasize the need for further tightening if data remain consistent with above-target inflation, while allowing flexibility on timing. Softer September payrolls (+29,000) and moderating wage growth have reduced odds of an October move, shifting focus to December. August CPI showed headline prices up 0.4% month-over-month and 3.4% year-over-year, with core at 2.4% annually, keeping the path to the 2% goal uncertain. The next CPI release on October 14 and the October 28–29 FOMC meeting will provide key updates ahead of the December decision.
