Core PCE MoM September 2026 prediction

The latest official figure on core inflation is the year-over-year reading: the Bureau of Economic Analysis page, dated September 30, 2026, shows the core PCE price index up 3.0% from a year earlier in August, the same as July and June, and down from 3.2% in May. That is the trend. It is not the number that decides this question. The deciding measure is the one-month change in core PCE, excluding food and energy, for September 2026, seasonally adjusted and rounded to one decimal. The BEA page was read on October 3, 2026, and it does not yet publish that figure. Nothing cited from elsewhere is that figure. So the forecast leans against a 0.3% print for a plain reason: the question asks for one specific rounded tenth, and the other tenths remain available. The steady 3.0% annual pace in recent months is the only recent core reading in the supplied evidence, and it does not pin down any single month's rounded change. An older June record in the packet carries no publication date and is labelled 2025, so I am not using it. BEA's own schedule, in records dated September 30, 2026, lists the September Personal Income and Outlays release for October 29, 2026, at 8:30 a.m. Eastern. Until then this is a call on an unpublished number. What to watch: that release itself. A core monthly change printed at 0.3% would overturn this forecast.
