FX.co ★ Indonesia’s Monthly Inflation Edges Up to 0.30% in September 2026

Indonesia’s month‑on‑month inflation picked up in September 2026, with the rate reaching 0.30%, up from 0.21% recorded in August 2026. The latest data, updated on 1 October 2026, indicate a modest acceleration in consumer price growth compared with the previous month.

On a month‑over‑month basis, the “actual” figure for September reflects the change in prices relative to August 2026, while the “previous” figure represents the change in August compared with July 2026. The move from 0.21% to 0.30% suggests a slight firming in short‑term price pressures, which will be closely watched by market participants and policymakers assessing the near‑term inflation trend in Indonesia.
