In the first half of October 2026, the annual general inflation rate in Mexico stood at 3.62% , after the National Consumer Price Index (INPC) increased 0.41% compared to the previous two weeks, the National Institute of Statistics and Geography (Inegi) announced .
The result represented an improvement compared to the 3.42% recorded in the first half of September, although it remained slightly below the 3.63% observed in the same period of 2025.
“The year-on-year variation accelerated for the third consecutive time, due to pressures in agricultural and energy products, accompanied by a rebound in the core index, after it slowed down between August and September,” explained the Financial Group Ve por Más (BX+) .
According to INEGI, the core inflation index —which excludes highly volatile goods and services— rose 0.25% on a biweekly basis . Within this index, merchandise prices increased 0.17% and services prices rose 0.31%.
“The increase in the underlying asset was the largest for a first half of October since 2022, highlighting the rise in air transport prices, partly reflecting a seasonal pattern and, in addition, possible pressures from fuel costs,” BX+ stated in an analysis.
Meanwhile, the non-core price index —which includes goods and services whose prices are subject to fluctuations— rose 0.98% biweekly . Prices for agricultural products fell 0.11%, while energy prices and government-regulated tariffs increased 1.85%.
This latest increase was driven by the end of the summer electricity subsidy in 18 cities across the country, a seasonal adjustment that put pressure on the overall indicator.
Electricity and air transport on the rise
Among the products with the greatest price increases in the first half of October were electricity with an increase of 18.51%, air transport with 14.77%, green tomatoes with 22.07%, zucchini with 16.27%, and LP domestic gas with a bi-weekly increase of 1.38%.
In contrast, the price of lemons fell by 10.43%, avocados by 4.79%, oranges by 4.58%, bananas by 4.15%, tomatoes by 3.04%, and potatoes and other tubers by 2.53% on a bi-weekly basis.
The behavior shows that the bi-weekly rebound was mainly concentrated in energy and some services, while the underlying component maintained moderate increases.
In that regard, the Ve por Más Financial Group considered that the inflationary outlook is still challenging and that the variable could accelerate “somewhat more towards the end of the year”.
