Mexican Mid-month CPI (Sep YY) 3.42% vs. Exp. 3.37% (Prev. 3.26%)

Episodes of this kind, where headline inflation drifts back up mid-cycle, have historically slowed the pace of cuts rather than reversed them, particularly when the move sits within or near the upper half of the tolerance band around target. The distinction that matters for MXN and TIIE pricing is between the headline and the core: Banxico's own framing has consistently given more weight to core and services stickiness, so a headline-only uptick tends to fade from the rates path unless the core confirms it. The mid-month print is the leading indicator for the full-month CPI release later in the month, which is the input the board actually deliberates on, and the usual sequence is that the swap curve reprices the size and timing of the next cut on that confirmation. Watch for the core breakdown in the full print and for any shift in tone from Banxico's more dovish members, who have previously driven split votes in this cycle.
