Indonesia Consumer Inflation Climbs to 3.19% in August
In this article (7)
Indonesia’s headline inflation jumped to 3.19 per cent year on year in August 2026, driven by rising grocery bills, gold jewelry costs and higher transport fares.
The increase from 2.28 per cent in July lifted the national consumer price index to 111.97 from 108.51 a year earlier, according to the Central Statistics Agency (BPS). The headline print remains inside Bank Indonesia’s target corridor of 2.5 per cent plus or minus one percentage point.
Food and Personal Care Drive Basket Costs
Food, beverages and tobacco delivered the heaviest punch to household budgets, climbing 3.86 per cent and adding 1.13 percentage points to the headline number. Broiler chicken, fresh fish, cooking oil and rice led the increases alongside bird’s eye chili, beef and cigarettes. Volatile food prices alone advanced 4.06 per cent over the twelve months.
Personal care and other services recorded the steepest category increase at 9.25 per cent, contributing 0.63 percentage points. High retail demand and elevated prices for gold jewelry accounted for most of that category gain.
Transportation expenses climbed 4.79 per cent from August 2025, adding 0.58 percentage points to headline inflation. BPS Deputy for Distribution and Services Statistics Ateng Hartono said higher gasoline prices, costlier airfares, vehicle lubricants, and rising prices for cars and motorcycles drove the transport index up.
Core Price Pressures Across Provinces
Core inflation, which strips out volatile food and government-regulated tariffs, stood at 2.92 per cent year on year. It contributed 1.87 percentage points to the overall index, buoyed by gold jewelry, prepared rice meals, cooking oil, mobile phones and laptops. Government-administered prices rose 3.32 per cent on higher household fuel and air travel costs.
All 38 Indonesian provinces recorded annual price increases during the month. North Maluku logged the country’s highest regional inflation at 5.28 per cent, while North Kalimantan posted the lowest reading at 2.17 per cent.
For consumer brands and supermarket operators, the sharp uptick in poultry and staple grain prices tests grocery basket sizes after a period of quiet monthly deflation in July. Packaged food manufacturers face immediate margin pressure across basic cooking ingredients, while discretionary retailers must contend with higher transport outlays eating into urban household disposable income.
Bank Indonesia next reviews its benchmark policy rate later this month, with policymakers balancing rupiah stability against the latest pickup in core consumer prices.
