Brazil’s General Market Price Index (IGP-M) posted a sharp turnaround in September 2026, advancing 1.57% month-over-month after recording a 0.22% decline in August. The latest figure, updated on 29 September 2026, underscores a marked reversal in price dynamics within just one month.

In August 2026, the IGP-M had fallen by 0.22% compared with July, signaling a brief period of deflationary pressure. By contrast, September’s 1.57% rise shows a robust rebound, indicating that price pressures have strengthened again across the components captured by the index.

On a month-over-month basis, the September result (actual) is measured against August’s performance (previous), highlighting the speed and magnitude of the shift in inflation momentum. Market participants and analysts will likely scrutinize the drivers behind this swing to gauge whether the September jump signals a temporary adjustment or the start of a more persistent upward trend in Brazilian wholesale and contract-based prices.
