Mexico’s Inflation Re-Accelerates At The Start Of 2026, Testing Rate-Cut Optimism

Key Points

• Headline inflation rose to 3.77% year on year in the first half of January, up from late December.
• Core inflation stayed higher at 4.47%, suggesting price pressures remain embedded beyond volatile items.
• The mix of rising everyday costs and easing energy and travel prices complicates the central bank’s next steps.

Mexico began 2026 with consumer inflation ticking up again. It is a reminder that disinflation rarely moves in a straight line. Fresh data from INEGI show prices increased 0.31% over the first half of January.

The update covers the first 15 days. The annual rate rose to 3.77%, from 3.69% at the end of December 2025. Core inflation, which strips out the most volatile items, climbed 0.43% in the fortnight.

It reached 4.47% year on year. Non-core inflation moved the other way. It fell 0.12% over the period and stood at 1.43% annually. That points to calmer swings in energy and some food items.

Behind the national average, price changes varied widely by place and product. INEGI’s regional breakdown showed Yucatán, Campeche, and Quintana Roo posting above-average fortnightly increases.

Durango and Baja California Sur recorded declines. The item list points to a familiar pattern for households. Cigarettes and bottled soft drinks rose notably.

Prices also increased at small, informal food outlets, where many workers buy daily meals. Offsetting those gains, air transport fell sharply. Eggs and household LPG gas also declined, offering relief in common baskets.

For policymakers, the headline number remains inside the target band. Banxico aims for 3% inflation, with a tolerance of plus or minus one point. Yet the core rate matters more for rate decisions.

A 4.47% reading suggests underlying pressure is still sticky. That can slow the pace of interest-rate cuts. For businesses and families, the message is practical.

Some visible prices can fall, while everyday costs keep grinding higher. That mix can prolong uncertainty for wages, contracts, and borrowing costs early in 2026.
