FX.co ★ Brazil’s September CPI Climbs to 4.58% YoY, Extending Inflation Pickup

Brazil’s consumer price inflation accelerated in September 2026, with the year-over-year CPI reaching 4.58%, up from 4.22% in August 2026. The figures, updated on 9 October 2026, confirm a continued upward drift in prices as measured against the same period a year earlier.

Both the current and previous readings are calculated on a year-over-year basis, comparing each month’s price levels to those of the corresponding month in the prior year. The move from 4.22% in August to 4.58% in September indicates that inflationary pressures have strengthened, potentially reinforcing the perception that price dynamics remain a central concern for policymakers and market participants in Brazil.
