Recent September core PCE data at 0.3% month-over-month, matching expectations and lifting the year-over-year rate to 3.1%, anchors trader focus on whether October sustains that pace or moderates. With 0.3% and 0.2% outcomes nearly tied in implied probability, markets reflect uncertainty over fading energy pressures, softer CPI components such as gasoline and vehicles, and resilient but cooling consumption trends. The Fed’s preference for additional data before policy shifts, combined with the November 25 release timing ahead of the December FOMC, keeps the contest tight as traders assess if underlying price pressures will align with the central bank’s 3.4% 2026 median projection or ease further.
