Indonesia’s Inflation Cools to 3.48% in March as Price Volatility Eases

JAKARTA, Investortrust.id — Indonesia’s inflationary heat showed signs of subsiding in March as the headline consumer price index (CPI) rose 3.48% on an annual basis, a marked deceleration from the 4.76% pace recorded in February.

Statistics Indonesia (BPS) reported on Wednesday that the CPI climbed to 110.95 in March 2026, up from 107.22 a year earlier. Ateng Hartono, BPS Deputy for Distribution and Service Statistics, noted that while the annual figure cooled, the economy continues to grapple with specific pressure points in housing, utilities, and personal care.

This cooling trend provides much-needed breathing room for Bank Indonesia, the nation's central bank. The significance of this data lies in its timing: as Indonesia enters the peak consumption period of Ramadan and the Idulfitri holidays, the deceleration in headline inflation suggests that previous fiscal interventions—including energy price caps—are successfully blunting the impact of global commodity volatility. However, the persistence of "administered price" inflation indicates that the government’s budget remains the primary shock absorber for the public.

Utilities and Gold Drive Annual Gains

The housing, water, electricity, and household fuel category emerged as the most significant contributor to the annual figure, posting a 7.24% gain. This sector alone accounted for a 1.08 percentage point contribution to the total inflation rate, driven primarily by adjustments in electricity tariffs.

Personal care and other services also saw a dramatic jump of 15.32%, fueled by the global rally in gold prices. Meanwhile, the food, beverage, and tobacco group—a critical component for the country’s lower-income households—rose 3.34% year-over-year. BPS officials pointed out that the first quarter of 2026 is facing a "low base effect" due to electricity discounts offered by the government in early 2025.

The Ramadan Consumption Spike

On a sequential basis, prices rose 0.41% in March compared to February. This monthly uptick was almost entirely driven by the "volatile foods" category, which rose 1.07% as households stocked up for the Islamic holy month of Ramadan.

Key commodities driving the monthly increase included fresh fish and poultry, significant drivers of protein inflation; rice and eggs, essential staples that remain sensitive to supply chain shifts; and lastly chili and cooking oil, traditional triggers for Indonesian CPI volatility.

After months of fueling inflationary heat, airfares and gold jewelry cooled in March, providing a modest 0.03 percentage point drag each on the overall monthly climb.

Regional Disparities and Core Strength

The inflationary experience remains fragmented across the archipelago. Aceh province recorded the nation’s highest annual inflation at 5.31%, while Lampung saw the lowest at a mere 1.16%. In terms of monthly gains, the remote Papua Highlands saw a staggering 2.57% increase, contrasting with a 0.75% deflationary trend in Maluku.

Core inflation, the metric closely watched by policymakers to gauge long-term trends, stood at 2.52%. This component was influenced by diverse factors including gold jewelry, higher education tuition, cooking oil, and house rentals.

Government-regulated prices, or "administered prices," rose 6.08% annually. This segment continues to be pressured by electricity costs and the rising prices of machine-rolled (SKM) and hand-rolled (SKT) clove cigarettes—staple consumer goods that face periodic excise tax hikes.
