Inflation rises to 3.45% in September as fruit and vegetable prices climb nearly 9%

What does Mexico’s 3.45% annual inflation rate mean for prices in September?

Annual inflation compares the overall cost of a consumer basket with its cost 12 months earlier. Mexico’s 3.45% rate therefore means that basket cost 3.45% more in September 2026 than in September 2025. It does not mean every product became exactly 3.45% more expensive.

INEGI also reported a 0.42% increase from August to September. Different categories moved at different speeds. Fruit and vegetables rose 8.78% annually, while meat prices fell 4.46%. These changes combine into one weighted headline measure, reflecting household spending patterns.

The September rate rose from 3.26% in August and marked a second consecutive monthly increase. It remained inside Banxico’s tolerated 2%-4% range, although above its 3% target. The next policy meeting is scheduled for Nov. 5, when the board can assess whether inflation is moving sustainably toward that target.

How much did fruit and vegetable prices increase, and how did that compare with meat prices?

Fruit and vegetables recorded an 8.78% annual price increase in September. That was the largest increase among the goods and services categories tracked by INEGI. Meat prices, by contrast, declined 4.46% over the same period. The gap shows why an overall inflation rate can hide sharply different experiences across products.

INEGI groups fruit, vegetables and meat within broader agricultural goods. That category rose 0.79% annually, because the strong fruit and vegetable increase was partly offset by falling meat prices. Agricultural prices therefore did not rise as quickly as the most expensive individual subgroup.

These figures matter because food purchases are frequent and visible to households. The article does not quantify their effect on each family’s budget, but food categories can influence the headline index when their prices change. September’s overall annual inflation was 3.45%, while core inflation, excluding volatile food and energy, was 3.75%.

Why did headline inflation rise even though core inflation fell from 3.88% to 3.75%?

Headline inflation covers the broad consumer basket, including volatile food and energy prices. Core inflation removes those volatile categories to show underlying price pressure more clearly. Because the two measures include different items, headline inflation can rise even when core inflation falls.

In September, annual headline inflation increased from 3.26% to 3.45%. At the same time, core inflation declined from 3.88% to 3.75%. Fruit and vegetable prices rose 8.78% annually, while energy prices, including electricity and gasoline, rose 3.81%. These movements contributed to the broader headline result, while the core measure excluded volatile food and energy prices.

The split suggests that September’s increase was not driven by a broad acceleration across core items. Services still recorded 4.27% annual inflation, and processed food, beverages and tobacco reached 4.57%. Banxico will next review conditions at its Nov. 5 monetary policy meeting, with its 3% target and 2%-4% range as reference points.

What effect can a rise in food prices have on Mexican households and on the inflation rate measured by INEGI?

A rise in food prices reduces what households can buy with the same income. Families may spend more on meals and have less available for other purchases. The effect varies by household because spending patterns differ, but food is a regular part of most budgets. The article itself does not measure household impacts.

INEGI’s headline index combines price changes across many goods and services. When food categories rise, their weighted contribution can lift the overall index. In September, fruit and vegetable prices rose 8.78% annually, while meat prices fell 4.46%. Broader agricultural goods prices increased 0.79%, showing that individual food movements can offset one another.

The September headline rate reached 3.45%, up from 3.26% in August. Core inflation fell to 3.75% because it excludes volatile food and energy prices. This means food can raise headline inflation without necessarily signaling a similar increase in underlying price pressure. Banxico monitors both measures when considering policy.

How close is Mexico’s 3.45% inflation rate to Banxico’s 3% target and its tolerated range of 2% to 4%?

Banxico targets annual inflation at 3% but tolerates outcomes between 2% and 4%. Mexico’s September headline rate was 3.45%. That puts inflation 0.45 percentage points above the target, while keeping it 1.45 points above the bottom of the range and 0.55 points below the top.

The comparison shows that inflation is not at the center of Banxico’s preferred target, but it remains within the stated tolerance band. The rate rose from 3.26% in August, so its direction was less favorable in September. It was also the highest annual rate since May, although below the 4.59% peak recorded in March 2026.

Core inflation was higher than headline inflation at 3.75%, despite falling from 3.88% in August. Banxico’s board had maintained its benchmark interest rate at 6.50% two weeks before the data release. Its next monetary policy meeting is scheduled for Nov. 5.

What tools can the Bank of Mexico use, especially interest-rate changes, to bring inflation back toward its target?

The Bank of Mexico uses monetary policy to influence demand and inflation. Its main tool is the benchmark interest rate. Higher rates generally make loans more expensive and saving more attractive, which can reduce spending and investment over time. Lower rates can support demand, but may be less appropriate when inflation is above target.

Banxico can raise, hold or cut its benchmark rate. It can also guide expectations through policy statements and use market operations to keep short-term conditions aligned with its decision. These broader tools are established central-bank practices; the article specifically reports only the benchmark rate and the board’s decision to maintain it.

The board kept the benchmark rate at 6.50% two weeks before September’s inflation figures were published. Headline inflation was 3.45%, above the 3% target but inside the 2%-4% tolerance range. Core inflation fell to 3.75%. Banxico’s next meeting, on Nov. 5, is the next stated policy checkpoint.

How is an inflation index built from the changing prices of many goods and services, and why can volatile items such as food and energy move it sharply?

An inflation index tracks how the cost of a representative basket changes over time. Statistical agencies assign weights based on how much households typically spend on categories such as food, services, goods and energy. They collect prices, compare the basket with an earlier period, and combine the category changes into one index. INEGI reported the national consumer price index at 146.075 in September.

The basket can contain items moving in opposite directions. Fruit and vegetable prices rose 8.78% annually, while meat prices fell 4.46%. Energy, including electricity and gasoline, rose 3.81%. Their different weights and movements were combined into September’s 3.45% annual headline inflation and 0.42% monthly increase.

Volatile items can change quickly because weather, harvests, fuel costs or other short-term conditions affect prices. Core inflation excludes volatile food and energy to show underlying pressure more clearly. In September, core inflation was 3.75%, below headline inflation’s 3.45%? Actually, it was higher at 3.75%, despite falling from August.
