Brazil’s official mid-month inflation gauge rose 0.32% in October, slower than the 0.43% economists expected, IBGE said on Friday 23 October at 8:00 a.m. ET. It was a sharp slowdown from 0.70% in September, but the yearly rate still climbed to 4.62%, above the ceiling of the central bank’s tolerance range, a key reading for Brazil inflation watchers.
The data lands two days before the presidential runoff and 12 days before the central bank’s next rate decision. For dollar investors in the Brazil economy, it says that price pressure is cooling in power bills and airfares but not at the supermarket.

Why the Yearly Rate Still Rose
Twelve-month inflation moved up from 4.47% to 4.62% because this October’s 0.32% replaced a much lower 0.18% from October 2025. A slower month can therefore still lift the yearly figure.
Prices are up 4.15% so far in 2026. Ten of the 11 areas surveyed saw increases, led by Belém at 0.76%, while Curitiba fell 0.27% on cheaper flights and water bills.
What It Means for US Readers
The central bank has cut the Selic rate to 13.75% in five steps since March. A below-forecast month supports further cuts, but a yearly rate above 4.5% argues for caution, which matters for Brazilian bonds and ADRs such as Itaú (ITUB) and Nubank (NU).
Travellers may find cheaper flights inside Brazil, while the cost of a restaurant meal rose 0.61%. The real barely moved at about 5.05 per US dollar in morning trading.
What Is Not Known
It is not known whether the food spike will last into November, since tomato prices are volatile. The full October IPCA, the figure the central bank uses for its target, is due on 12 November.
What Prediction Markets Say
- Polymarket, “Bank of Brazil decision in November?”: 25 bps decrease 84.5%, no change 14.2%, 50+ bps decrease 1.7% (US$73,755 traded).
