Indonesia’s annual inflation rate picked up in January 2026, rising to 3.55% year-over-year, according to data updated on 2 February 2026. This marks an acceleration from December 2025, when inflation stood at 2.92% on a year-over-year basis.
The figures show that price pressures have strengthened at the start of 2026, with the latest reading comparing the change in prices in January 2026 to those in January a year earlier. The previous indicator measured December 2025 against December of the prior year. The move from 2.92% to 3.55% suggests inflationary dynamics are gaining momentum, which will be closely watched by policymakers and financial markets assessing the outlook for interest rates and household purchasing power in Indonesia.
