FX.co ★ Indonesia’s Core Inflation Edges Up to 2.59% in May, Signaling Mild Price Pressures

Indonesia’s core inflation rose to 2.59% year-over-year in May 2026, up from 2.44% in April, according to the latest data updated on 2 June 2026. The reading indicates a modest pickup in underlying price pressures, measured by stripping out volatile components such as food and energy.

The move from 2.44% to 2.59% suggests that while core price growth remains contained, underlying demand and cost dynamics are firming compared with the same period a year earlier. Both the April and May figures are calculated on a year-over-year basis, comparing each month’s core inflation with its level in the corresponding month of the previous year.

With core inflation still within a moderate range but on a gentle upward path, investors and policymakers will be watching upcoming releases closely for signs of whether this trend consolidates or stabilizes in the coming months.
