BPS East Java: Cooking Oil to Onions Drive May Inflation to 1.43 Per Cent

The Central Bureau of Statistics (BPS) has recorded that East Java Province experienced an inflation rate of 1.43 per cent in May 2026 compared to April 2026 (month-to-month/mtm). This increase was driven by rising air transport fares and the prices of food commodities, including cooking oil, shallots, bird’s eye chillies, red chillies, and rice.

“The Consumer Price Index (CPI) rose from 108.06 in May 2025 to 111.83 in May 2026,” stated the Acting Head of BPS East Java, Herum Fajarwati, during a press conference in Surabaya, East Java, on Tuesday.

Herum noted that inflation in East Java last month was underpinned by several factors, such as the increasing cost of industrial raw materials sourced from imports. Additionally, rising prices for various plastic-based products exerted pressure on several commodities, ranging from electronic equipment to bottled water.

Furthermore, food price dynamics influenced May’s inflation, as limited supplies of certain food commodities, such as rice, chillies, and onions, drove price pressures.

In detail, air transport experienced inflation of 5.04 per cent with a contribution of 0.07 per cent; cooking oil rose by 3.96 per cent with a contribution of 0.05 per cent; shallots increased by 11.5 per cent with a contribution of 0.05 per cent; bird’s eye chillies rose by 10.02 per cent with a contribution of 0.04 per cent; and red chillies surged by 31.93 per cent with a contribution of 0.04 per cent.

Other notable increases included rice at 0.67 per cent with a contribution of 0.03 per cent, laptops/notebooks at 2.98 per cent with a contribution of 0.03 per cent, household fuel at 1.47 percent with a contribution of 0.02 per cent, and bottled water at 1.3 per cent with a contribution of 0.02 per cent.

Conversely, several commodities experienced deflation, including gold jewellery at -3.09 per cent, chicken eggs at -6.16 per cent, chicken meat at -2.4 per cent, and garlic at -4.58 per cent.

Across the 11 regencies and cities in East Java, all experienced inflation. The highest rate was recorded in Surabaya at 0.37 per cent, while the lowest was in Probolinggo City at 0.03 per cent.
