Persistent inflation and recent hawkish signals from Federal Reserve officials are driving the near-97% market-implied odds of another federal funds rate increase before year-end. October CPI data showed core prices rising 0.3% month-over-month for the third straight month, exceeding expectations, while officials including Governors Christopher Waller and Dallas Fed President Lorie Logan have explicitly backed at least one 25-basis-point hike at the December 8-9 FOMC meeting, with some open to 50 basis points. Economist surveys reflect unanimous consensus for a December move to the 4.00%-4.25% target range, building on the September increase. The primary catalyst remains above-target PCE and CPI readings alongside resilient growth. A tail-risk scenario that could alter the outcome would require unexpectedly soft November data or a sharp policy reversal ahead of the meeting.
