Brazil’s IGP‑10 inflation index moved sharply back into positive territory in September 2026, reaching 1.5% month-over-month, according to data updated on 16 September 2026. The shift marks a significant rebound from August 2026, when the index had registered a 0.5% deflation (-0.5%) compared to the previous month.

The month-over-month comparison shows a clear inflection in price dynamics: while August reflected a contraction in the IGP‑10, September’s reading points to renewed inflationary pressure. The “Actual” figure for September (1.5%) is measured against August’s change, whereas the “Previous” figure for August (-0.5%) was calculated relative to July, underscoring the strength of the turnaround within just one monthly cycle.

The abrupt move from negative to positive territory in the IGP‑10 will be closely watched by market participants and analysts, as it may signal a change in the short-term inflation trend heading into the final quarter of 2026.
