Recent softening in the August core PCE reading to 0.2% month-over-month, below the 0.3% consensus, alongside downward revisions to prior months and a 3.0% year-over-year rate, has anchored trader expectations for a similar 0.2% September outcome at 32% implied probability. This print, released alongside strong consumer spending, reinforced Fed officials' signals of no urgency for an October rate hike after the September tightening, shifting focus to December while inflation stays well above the 2% target. Key swing factors include incoming CPI and PPI prints, potential seasonal effects, and any further annual revisions, with the October 29 release arriving just ahead of the FOMC meeting and leaving a wide distribution across outcomes from 0.1% or lower to 0.5%+.
