Mexico’s core Consumer Price Index (CPI) rose 0.20% month-over-month in September 2026, edging up from a 0.16% increase in August, according to data updated on 8 October 2026. The core CPI excludes volatile items and is closely watched as a gauge of underlying inflation trends.
The acceleration, though modest, indicates that price pressures in the Mexican economy remain persistent. On a month-over-month basis, September’s reading shows a slightly faster pace of underlying inflation compared with the previous month, when August’s 0.16% gain reflected a softer increase versus July.
The data, measured on a month-over-month comparison, suggest that while headline inflation dynamics are not provided, the core component is not yet showing a clear easing trend. Market participants and policymakers are likely to view the uptick from August to September as a sign that inflation risks remain present heading into the final quarter of 2026.
