Mexican Mid-month Core CPI (Aug YY) 3.93% (Prev. 3.95%)

A marginal downtick in mid-month core inflation, effectively flat against the prior reading, sits within the kind of gradual disinflation path Banxico has conditioned its easing cycle on: the board has historically moved in measured steps while core remains above target, and incremental cooling of this sort has tended to validate continuation rather than acceleration. The mid-month print is the early read on the full-month CPI due shortly after, and episodes where the two diverge have typically seen the market defer to the fuller release. The distinction worth drawing is between core and headline: Banxico's reaction function has leaned more heavily on the core trend and on services stickiness within it, so the composition of the follow-up print matters more than the small move here. The transmission runs through the front end of the TIIE curve and the MXN carry trade, where positioning around the pace of cuts has been the dominant driver. The follow-ons are the full-month CPI and the next Banxico decision, with any shift in the board's split voting pattern the usual tell.
