Persistent inflation above the Federal Reserve’s 2% target remains the dominant driver of trader sentiment on the federal funds rate path before 2027. September 2026 CPI rose 0.6% month-over-month to 3.7% year-over-year, with core CPI at 2.6%, fueled by energy prices and resilient demand. After the September 25-basis-point hike to the 3.75–4.00% range, the median dot plot projects 4.1% by year-end 2026. Markets now assign elevated odds to a December increase, with the terminal rate potentially reaching 4.25% or above amid hawkish official commentary. Key upcoming catalysts include the October 27–28 FOMC decision and December meeting with updated projections, alongside fresh CPI and labor data that could shift rate expectations.
