Mexico’s consumer price inflation inched higher in September 2026, interrupting the recent easing trend and edging further above the 3% mark. Year-over-year CPI rose to 3.45% in September, up from 3.26% recorded in August 2026, according to data updated on 8 October 2026.
The figures are based on year-over-year comparisons, measuring price changes in each month against the same month a year earlier. The latest reading suggests a mild reacceleration in price pressures after a period of gradual disinflation, and will likely be closely monitored by market participants assessing the outlook for monetary policy in Mexico.
With inflation still contained but no longer slowing, investors and analysts will watch upcoming releases to determine whether September’s uptick represents a temporary fluctuation or the start of a more persistent upward move in consumer prices.
