Mexico's inflation rises to 3.62% in the first half of October as electricity jumps 18.51%, INEGI says

The end of the summer electricity subsidy in 18 cities was the main driver; airfares also rose.

Consumer prices in Mexico rose 0.41% in the first half of October 2026 from the previous two weeks, lifting annual inflation to 3.62%, the National Institute of Statistics and Geography (INEGI) reported on Thursday, October 22.

The two-week increase was larger than in the same period of 2025, when prices rose 0.28% and the annual rate stood at 3.63%. The National Consumer Price Index (INPC) stood at 146.739 points.

What pushed prices up

According to INEGI, the biggest upward pressure came from electricity, which rose 18.51% in the period. The increase reflects the end of the warm-season electricity rate program in 18 Mexican cities: once the summer subsidy ends, bills return to regular rates, and that shows up in the index.

Other items with notable increases were green tomatoes (tomatillo), zucchini and air travel.

Underlying inflation

Core inflation — which strips out the most volatile prices, such as farm products and energy, and is used to gauge the trend — rose 0.25% in the period and reached 3.78% year over year. Within it, goods rose 0.17% and services 0.31%.

Non-core prices climbed 0.98%, driven by energy and government-set tariffs, while farm products overall fell 0.11%.

Both the headline and core figures remain above the Bank of Mexico's 3% inflation target, though within its tolerance band of plus or minus one percentage point.

What it means for your wallet in Cancún

  • Check your power bill. The national figure reflects the return to unsubsidized rates in cities where the summer program has ended. If your bill went up, compare this period's kilowatt-hours with the previous one on your bill or in the CFE Contigo app to see whether the increase comes from the rate or from your usage.
  • Airfares. If you plan to fly elsewhere in Mexico over the year-end holidays, the rise in air travel prices is a reason to compare fares early and across airlines.
  • Groceries. Farm products fell overall, but some, such as tomatillos and zucchini, went up. Before a big grocery run, consumer agency Profeco publishes store-by-store price comparisons in its "Quién es Quién en los Precios" tool (gob.mx/profeco).
  • Savings and loans. With inflation at 3.62%, cash that earns nothing loses purchasing power at that pace; a savings product paying less than that yields below zero in real terms.

INEGI will publish the second-half and full-month October figures in November, according to its release calendar.
