FX.co ★ Indonesia’s Core Inflation Eases to 2.84% in September, Signaling Mild Price Pressures

Indonesia’s core inflation slowed slightly in September 2026, easing to 2.84% year-over-year from 2.92% in August, according to data updated on 1 October 2026. The latest figure suggests that underlying price pressures in Southeast Asia’s largest economy remain contained.

The year-over-year comparison shows that while prices are still rising compared with the same month a year earlier, the pace of increase has moderated between August and September. The “previous” reading of 2.92% reflected August’s change versus August a year earlier, while the “actual” 2.84% captures the change in September relative to September of the prior year.

The slight deceleration in core inflation may be viewed as a sign of relative price stability, potentially giving policymakers more room to balance inflation control with growth considerations, depending on broader economic conditions and forthcoming data releases.
