FX.co ★ Brazil’s IGP-DI Inflation Surges to 1.50% in September, Marking Sharp MoM Acceleration

Brazil’s IGP-DI inflation index registered a strong month-over-month acceleration in September 2026, rising 1.50% compared with a modest 0.06% increase in August 2026, according to data updated on 7 October 2026.

The move represents a pronounced shift in the month-over-month dynamic: while August’s reading showed inflation essentially flat, September’s result points to a significantly faster pace of price increases captured by the IGP-DI. On a comparative basis, the “Actual” figure reflects the change in September versus August, whereas the “Previous” figure captures August’s change relative to July.

The sharp uptick in the index is likely to draw attention from market participants and policymakers, as the IGP-DI is closely watched as a broad measure of price pressures across the Brazilian economy. Investors will be monitoring upcoming releases to determine whether September’s acceleration signals the start of a new inflationary trend or a one-off jump in the indicator.
