Recent hotter-than-expected September CPI data, showing a 0.6% monthly rise and 3.7% annual inflation with core measures at 2.6%, has reinforced trader expectations for additional Fed tightening amid sticky price pressures. This aligns with the September FOMC dot plot, where 16 of 18 officials projected at least one more 25-basis-point hike by year-end, and recent comments from policymakers including Waller, Williams, and Collins signaling flexibility on timing but a need for further firming to reach the 2% target. Cooling September payrolls and subdued wage growth have reduced odds of an October move, concentrating market-implied odds on a December 25-basis-point increase. The Fed's current 3.75%-4.00% target range and upcoming data releases will shape final positioning ahead of the December FOMC meeting.
