Brazil’s IPCA-15 Inflation Preview Jumps 0.70% in September, Above Forecasts
Brazil · Economy
Key Facts
—The number. Brazil’s IPCA-15 inflation preview rose 0.70% in September 2026, reversing August’s 0.40% deflation; the year reads 3.82% and the 12-month rate 4.47%.
—The driver. Housing costs jumped 2.07%, led by a 7.42% rise in residential electricity as the Itaipu bonus expired and the yellow tariff flag took effect.
—The surprise. The print came in above the 0.55% median forecast of economists surveyed by the financial press — and above the top of their estimates.
—The breadth. All nine spending groups and all eleven regions surveyed by statistics agency IBGE rose; Goiânia posted the highest reading at 0.95%.
—The context. The 12-month rate of 4.47% sits just below the 4.5% ceiling of Brazil’s inflation target band; the Selic base rate stands at 13.75% after this month’s cut.
Brazil’s inflation preview snapped back from deflation, and the main driver lands directly on household budgets: the electricity bill.
What Drove the September Reading
Brazil’s statistics agency IBGE released the September IPCA-15 on Friday, 25 September 2026. The index — the mid-month preview of the country’s official inflation gauge — rose 0.70%, a swing of 1.10 percentage points from August, when it had fallen 0.40%.
The housing group posted the largest increase, up 2.07%, and within it residential electricity climbed 7.42%. Two forces combined: the expiry of the Itaipu bonus, which had discounted power bills in August, and the return of the yellow tariff flag, which adds a surcharge to bills. Piped gas was also readjusted in cities including Curitiba and Rio de Janeiro.
Personal expenses rose 0.96%, pulled by a 14% jump in cigarette prices. The print overshot expectations: economists had penciled in a median of 0.55%, and the result landed above the ceiling of their estimates, according to surveys published by Folha de S.Paulo and Estadão.
Food and Transport Turn Back Up
Food and beverages, which had been falling for months, rose 0.40%. Food consumed at home increased again, led by tomatoes at 20.76%, rice at 2.39% and meat at 1.30%. Moving in the opposite direction, carioca beans fell 6.33%, onions dropped 4.41% and ground coffee eased 1.36%.
Transport advanced 0.60% even as fuel prices declined on average: airfares jumped 9.82%. The remaining groups posted more moderate increases, from 0.03% in education to 0.55% in household goods. It was the first time in months that all nine groups moved higher together, and all eleven regions covered by the survey recorded positive readings — Goiânia highest at 0.95%, pressed by cigarettes and electricity.

What It Means for Rates
The 12-month reading accelerated to 4.47% from 4.24%, moving closer to the 4.5% ceiling of Brazil’s inflation target band, which centers on 3% with a tolerance of 1.5 points in either direction. The quarterly IPCA-E measure came in at 0.36%.
The central bank’s Copom cut the Selic to 13.75% on 16 September, and market pricing had been consolidating around a hold for the remainder of the year. A stronger-than-expected preview does not force the committee’s hand by itself — but it narrows the room for further easing if the full-month IPCA confirms the reacceleration in October.
What This Means
For households and the expat community, the transmission is immediate: electricity bills rise this month as the Itaipu credit disappears and the yellow flag adds its surcharge. Rent contracts indexed to broader inflation gauges will feel the 12-month rate only gradually.
The September print also closes a chapter: the same Itaipu bonus that produced August’s rare deflation reading has now unwound, returning the index to the inflationary path that had pushed the 12-month rate toward the top of the target band earlier this year.
What We Could Not Confirm
Whether the full-month September IPCA, due in October, will match the 0.70% preview is an open question. Market reaction in the Ibovespa and the real was still forming at the time of publication, and IBGE’s release does not break down city-level detail beyond the eleven regional readings cited above.
