Mexico’s upward inflation trend continued in September, reaching 3.76% at an annual rate , down from 3.57% last August, according to data published Thursday by the National Institute of Statistics and Geography (INEGI) .
This increase was framed by the core price index – which does not take into account the most volatile goods and services – which increased 0.33% monthly , with a rise in the prices of merchandise of 0.34% and services of 0.32 percent .
Meanwhile, the non-core price index , which includes goods and services whose prices are subject to fluctuations such as weather conditions, decreased 0.10% monthly . Within this index, agricultural product prices fell 0.14% and energy prices fell 0.06% .
Products with price increases and decreases
The INPC’s behavior in the ninth month of the year caused a price increase for products such as serrano peppers (17.60%), green tomatoes (12.93%), onions (8.05%), and beef (0.92%). It also increased the price of some services, such as primary school tuition , which rose 5.98%, and university tuition , which rose 1.82%.
On the other hand, the products with the greatest price decrease in September 2025 were avocados , with a price decrease of 11.34%, oranges with a 7.74% decrease, air transportation with a 4.27% decrease, eggs with a 2.28% decrease, and domestic LP gas with a decrease of 0.67%.
Chiapas, Aguascalientes, and Tlaxcala were among the country’s states with a variation below the national average in the INPC, while Sonora, Mexico City, and Tamaulipas were the states with the largest increases in this indicator.
The increase in prices for some basic products contributed to the rise in inflation in September 2025.
The figures come in the context of a slower Mexican economy , where consumers have been cautious when purchasing goods and services.
