Mexico's October inflation rose to 3.75% after Banxico had cut rates to 6.25%. The sequence shows why remaining inside a target band is not the same as reaching the goal.

Mexico's inflation report has arrived in an awkward order for its central bank. On November 5, Banco de México lowered its benchmark interest rate; on November 9, the statistics agency published figures showing that annual consumer-price inflation had accelerated again in October. The new reading was 3.75%, up from 3.45% in September. That was the third consecutive monthly increase in the annual inflation rate, not a third consecutive rise of that size in prices themselves.

The bank's quarter-point cut to 6.25% was made before the full October numbers were available. It was not a response to the November 9 release, and that release alone cannot establish that the decision was mistaken. What it does expose is a difficult distinction for policymakers and households: inflation can sit inside a central bank's permitted range while prices are still climbing faster than the bank's central objective.

## The numbers behind the October rise

INEGI's consumer price index reached 147.026 in October, a 0.65% increase from September. Its 3.75% annual rate compares the average measured basket with October 2025, whereas the monthly figure compares October with September 2026. The annual pace had been 3.26% in August and 3.45% in September. Reuters reported that economists surveyed before the release had expected a 3.65% annual rise. The actual reading exceeded that poll figure by 0.10 percentage points; it was not a 0.10% jump in the price level.

Underlying inflation, which excludes selected volatile or administratively influenced prices, rose to 3.80% annually from 3.75% in September. On a monthly basis, that core index gained 0.34%, rather than the 0.33% carried by an earlier radar draft. The non-core index rose 1.75% during October and was 3.59% above a year earlier. These readings matter together: the headline acceleration was not simply a single headline number detached from the behavior of the index's other components.

## Electricity and groceries do not move together

Price changes across the consumer basket were uneven. Contemporary reporting of INEGI's product tables put the October monthly rise in electricity at 18.51%, airfares at 26.36% and green tomatoes at 35.58%. Electricity was affected by the scheduled end of summer tariff subsidies in 18 surveyed cities. That is an important qualification: a seasonal tariff change in covered locations cannot be read as an identical increase for every electricity customer across Mexico, nor as evidence of the same pressure every month.

Some prices moved in the opposite direction. Reports based on INEGI's release identified declines in lemons, potatoes and bundled internet, telephone and pay-television services. The index combines such movements with weights representing household expenditure rather than giving every item an equal vote. Consequently, one family's electricity bill or produce purchases can diverge sharply from the national average. Nor does lower inflation on any future reading automatically reverse earlier increases: slower price growth is not the same thing as a fall in the overall price level.

## A divided board acted four days earlier

The November 5 decision lowered the overnight policy-rate target by 25 basis points, from 6.50% to 6.25%, effective November 6. The official monetary-policy announcement records three votes for the cut: Governor Victoria Rodríguez Ceja and Deputy Governors José Gabriel Cuadra García and Omar Mejía Castelazo. Deputy Governors Galia Borja Gómez and Jonathan Heath voted to leave the rate at 6.50%. This was a narrow majority, not an unanimous judgment that inflation risk had disappeared or that subsequent reductions were already approved.

The bank described the step in Spanish as an ajuste puntual, a specific adjustment, and said keeping the new rate for a prolonged period would support convergence toward its inflation objective. It pointed to spare capacity and limited expected pass-through from exchange-rate movements to consumer prices, while acknowledging risks to growth. The rate had been held at 6.50% in June, August and September after a reduction in May. A policy-rate decision is a judgment about the future path of prices and activity, not a retrospective vote on one forthcoming statistical release.

## Inside the band, still above the goal

Banxico's central inflation objective is 3%, surrounded by a tolerance interval extending from 2% to 4%. October's 3.75% headline reading and 3.80% core reading both fit within that interval. Being within the band, however, is not equivalent to reaching 3% or to achieving stable prices in everyday experience. An annual inflation rate of 3.75% means that, on average, the measured basket remained more expensive than twelve months earlier. The band is a way to assess deviations, not a guarantee about the cost of living.

The central bank revised its forecast for headline inflation in the fourth quarter of 2026 to 3.7%, up from its previous 3.5%. Its corresponding core forecast rose to 3.7% from 3.6%. These are forecasts for quarterly average year-on-year inflation, not verified full-quarter results or predictions of a 9% year-end rate. The bank still projects convergence to the 3% objective in the fourth quarter of 2027. That longer horizon is essential to understanding why one rate reduction and a subsequent high reading can coexist.

## Why a pause is a signal, not a promise

The November statement judged the balance of risks around its inflation projection to be tilted upward. It identified persistent underlying inflation, further peso depreciation, trade-policy disruptions, geopolitical conflict, climate impacts and cost pressures as possible sources of higher prices. It also listed weaker economic activity and reduced cost pass-through among the downside possibilities. This two-sided assessment explains why the board did not treat either subdued demand or a recent inflation rise as a simple instruction to move rates in one direction indefinitely.

Financial markets and forecasters may interpret the bank's preference for an extended hold as a pause in its easing cycle. Reuters quoted economists expecting the current rate to remain in place for some time. But the board did not pre-commit itself to a particular result at the next meeting. Changes in bank borrowing costs also reach households and firms gradually, through lenders' pricing, contracts and decisions about spending. There is no basis for promising an immediate reduction in loan payments just because the official overnight target moved lower.

## The next tests are already on the calendar

Banxico's published 2026 schedule sets November 19 for the minutes of its November 5 meeting and December 17 for the next policy announcement. The minutes may add detail about how members weighed inflation persistence against economic slack, although the names and votes are already disclosed in the announcement. New INEGI price figures will also help show whether October's energy and fresh-food changes persist, reverse or are offset by movements elsewhere. None of those later outcomes can be assumed in advance.

The decisive question is not whether a single October figure invalidates a November decision. It is whether the inflation path that justified a one-time cut remains credible as additional evidence comes in. A longer pause could follow even if annual inflation stays within the tolerance band; a different decision could follow if the outlook changes. For Mexican households, the distinction remains practical: the policy rate is a tool aimed at future inflation, while current supermarket and electricity prices reflect expenses they are already paying.
