US Core PCE Index (Aug MM) 0.2% vs. Exp. 0.3% (Prev. 0.1%)

A miss of one tenth against consensus on a series this smooth is the kind of deviation that has historically repriced the front end modestly unless it compounds a run of similar prints; what has moved the rate path is the sequence, since two or three consecutive soft core readings have tended to be the threshold at which pricing of the next meeting shifts decisively. The prior print rounding up from a low base is worth noting, as the year-on-year comparison and the supercore services ex-housing component typically draw more attention than the headline core when the monthly figure is ambiguous. The follow-ons are the income and spending detail in the same release, any revisions to prior months, and how Fed speakers in the days after frame the print against their stated reaction function. As a single soft tenth, the established pattern is a brief bull-steepening impulse at the front of the curve that fades absent corroborating data.
