Recent September CPI data, with core rising 0.3% month-over-month amid broad-based gains in services and goods, has anchored trader expectations for the September Core PCE release due October 29. Economist forecasts now cluster around 0.32–0.36% m/m after incorporating firmer CPI components and subsequent PPI details, supporting the 66% market-implied probability for a 0.3% print. This follows August’s softer 0.2% Core PCE reading and reflects persistent underlying inflation pressures that keep the year-over-year core rate near 3.1%. With the FOMC meeting one day prior and markets pricing a December rate hike, the outcome will influence near-term policy expectations while the 0.4% and 0.2% alternatives remain secondary possibilities if revisions or component details shift the final figure.
