In August 2026, Indonesia reported a national year-on-year inflation rate of 3.19 percent, with price increases observed across all expenditure groups. Regional variations were noted, with Lebak Regency in Banten recording the highest inflation at 4.00 percent due to rising costs in transportation, health, and personal care. Sumenep Regency in East Java followed with a rate of 3.99 percent, largely influenced by food, tobacco, and beverage expenditures.

In the Papua province, authorities are aiming to maintain an inflation rate of 3.5 percent through the end of 2026 to ensure stability during the holiday season. Local officials reported that Papua’s inflation remains among the lowest in the country, noting that essential food supplies such as rice and chili remain secure.
