Banxico's calendar gives eight dates and reserves the right to act on others
Banco de México's published calendar for 2026 sets out eight scheduled monetary policy announcements, delivered - as in 2025 - on Thursdays at 13:00 CST. September's date was the 24th. Minutes of the Governing Board's monetary policy meetings follow two weeks after each announcement, also on Thursdays, with December handled separately. Quarterly reports are dated in advance too: 26 February for Q4 2025, 27 May for Q1 2026, 26 August for Q2, 26 November for Q3.
One sentence in the document does more work than the rest of it. Banxico states that, as in previous years, it reserves the right to adjust its monetary policy stance on dates other than those pre-scheduled, should extraordinary events arise requiring the Central Bank's intervention.

What it means
That reservation is standard text and it is not decoration. For an emerging market central bank the calendar is a commitment device - it says surprises will arrive at known moments, which is worth real basis points in how foreign investors price the risk of holding local currency debt. The carve-out is the acknowledgement that the commitment has a limit, and in an economy exposed to external shocks the limit is the part that gets tested.
It is also worth reading next to today's ECB research finding that speeches and interviews between Governing Council meetings move markets as much as the formal decisions. Eight dates a year is eight decisions and a great deal of time in between; an institution that publishes a precise calendar for its announcements and its minutes has scheduled the formal channel tightly, which makes everything said outside that schedule the less governed half of its communication. The ECB work suggests that half is not smaller in effect.
For anyone positioning around Mexican rates, the practical items are the two-week minutes lag and the 26 November quarterly report covering Q3 - the minutes are where the distribution of views inside the Board becomes visible, and a calendar that fixes their release removes one source of noise while concentrating the information into a known instant. The genuinely unpredictable event remains the one the reservation clause exists for.
