FX.co ★ Indonesia’s Inflation Edges Up to 3.28% YoY in September 2026

Indonesia’s annual inflation rate inched higher in September 2026, rising to 3.28% year-over-year from 3.19% in August 2026, according to data updated on 1 October 2026. The figures are based on a year-over-year comparison, measuring the change in prices in each month against the same month a year earlier.

The latest reading suggests a modest acceleration in price growth, with September’s “actual” figure reflecting a slightly faster pace of inflation than in August. While the change is small, the uptick may draw attention from policymakers and market participants monitoring the trajectory of consumer prices through the second half of 2026.
