September 2026 Inflation Hits 3.28%
Statistics Indonesia (BPS) recorded September 2026 inflation at 0.30% month-to-month. The Consumer Price Index (CPI) rose from 111.97 in August 2026 to 112.31 in September 2026.
Year-on-year, inflation reached 3.28%, while year-to-date inflation stood at 2.17%. The data was released by BPS on Thursday (1/10/2026).
BPS Deputy for Distribution and Services Statistics Ateng Hartono said the food, beverages, and tobacco group was the main contributor to monthly inflation, with a 0.26% contribution and 0.88% inflation.
Chilies the Main Drivers
The commodities dominating inflation in the food, beverages, and tobacco group were bird's eye chili with a 0.08% contribution, red chili at 0.06%, broiler chicken at 0.05%, rice at 0.03%, broiler eggs at 0.02%, and water spinach at 0.01%.
BPS pointed to falling output as the culprit. Bird's eye chili production dropped in producing centers such as Garut, Temanggung, Bandung, Sampang, and Magelang, while red chili output fell in Bandung, Garut, and Malang.
The volatile-food component posted 1.46% inflation with the largest contribution of 0.24%, dominated by the same commodities.
Transportation Adds Pressure, 36 Provinces Inflate
Beyond food, transportation also pushed inflation, recording 4.84% with a 0.58% contribution — driven by high gasoline prices, airfares, lubricants, motorcycles, cars, and maintenance costs.
Regionally, 36 provinces recorded inflation and two recorded deflation in September 2026. The highest inflation was in North Sulawesi at 3.53%, while the deepest deflation was in East Nusa Tenggara at 0.35%.
With annual inflation at 3.28%, household purchasing power — especially for food and transportation — bears watching heading into year-end.
BPS also recorded core-component inflation of 0.10% with a 0.06% contribution, dominated by university tuition costs. The government-administered price component posted near-zero inflation.
Notably, gold jewelry was the main deflation driver in the personal-care group, contributing 0.01% to deflation. Overall, all three inflation components — core, administered prices, and volatile food — recorded inflation in September 2026, according to BPS data released on 1 October.
