Latest figures

The latest release for OCT, published on 22 October 2026, came in at 3.78%, above the consensus of 3.70%, down from 3.79% the time before.

A higher figure than expected makes the Banco de México (Banxico) more likely to keep rates high or raise them: it tends to support the Mexican peso and push bond yields up, and is often a weight on stocks.

Over the last 12 releases it ranged from 3.78% to 4.52%, averaging 4.21%; it has been falling for three releases in a row.

Why it matters

Food and energy prices jump with harvests and oil, then fall back. The core rate shows the underlying trend that the Banco de México (Banxico) can actually influence, so it often moves markets more than the headline. Services inflation, driven by wages, is the stickiest part.

How it is calculated

INEGI takes the consumer price index basket, removes the excluded items and re-weights the rest; the change is measured month on month and against the same month a year earlier.

Core inflation (yoy) = core index ÷ core index 12 months ago − 1

What changes mean

  • A core rate falling towards the target lets the Banco de México (Banxico) ease; a stubborn core keeps rates high.
  • Monthly core changes of 0.2% compound to about 2.4% a year; 0.3% to about 3.7%.
  • Markets compare the figure with the consensus to one decimal; a 0.1-point surprise moves currencies.

Higher than expected: A higher figure than expected makes the Banco de México (Banxico) more likely to keep rates high or raise them: it tends to support the Mexican peso and push bond yields up, and is often a weight on stocks.

Lower than expected: A lower figure than expected gives the Banco de México (Banxico) room to cut or hold rates lower: the Mexican peso tends to soften and bond yields to fall.

A short history

Economists Robert Gordon and others popularised excluding food and energy in the 1970s, when oil shocks made the headline rate misleading; most central banks now publish or watch a core measure.
