The rounded print beats consensus while the three-decimal detail tells a softer story, a combination that has historically split the reaction: the algos and the headline read the rounded miss against expectations first, and the follow-through depends on whether desks treat the deceleration in the unrounded series as the more informative signal. The core month-on-month run rate, annualised, sits well above target-consistent levels even at the lower unrounded figure, so the distinction between a 0.3 that is nearly 0.25 and one that is nearly 0.35 has mattered more than the rounding in past prints of this kind. The transmission is through the front end and the terminal-rate debate: firmer-than-expected core readings have tended to steepen the expected path or push out the timing of easing, with the belly and the dollar following the two-year. What has typically resolved the ambiguity is the composition, whether the heat is in shelter, where persistence is expected and discounted, or in core services ex-housing, which the central bank has flagged as its preferred gauge of underlying pressure. The follow-ons are the supercore detail, the revisions, and how the print interacts with the next labour data in the sequencing the committee has described. As a single month, one hot core print has rarely shifted policy on its own; two or three in succession have.
