December Inflation Climbs to 0.64% Monthly, 2.92% Annually, Aceh Tops Provinces

JAKARTA, Investortrust.id — Indonesia records inflation of 0.64% month on month and 2.92% year on year in December 2025 in Jakarta on Monday, Jan 5, 2026, as higher food prices and gold costs lift consumer prices while staying within the government and central bank target range. The increase reflects seasonal demand and supply disruptions, with Aceh posting the sharpest regional rise.

Statistics Indonesia said annual inflation and calendar-year inflation were identical because they compared the same CPI points. “Annual inflation and calendar-year inflation are the same because what is being compared are two identical points, namely the December 2025 CPI and the December 2024 CPI,” said Pudji Ismartini, Deputy for Distribution and Services Statistics.

On a monthly basis, the consumer price index rose to 109.92 in December 2025 from 109.22 in November 2025. Food, beverages, and tobacco recorded the largest increase at 1.66%, contributing 0.64 percentage points to overall inflation.

Key food commodities drove the rise, led by bird’s eye chili, followed by broiler chicken meat, shallots, fresh fish, and eggs. Personal care and other services also added to inflation, supported mainly by higher gold jewelry prices.

Transportation prices increased during the month, reflecting higher gasoline prices and airfares. At the same time, several commodities posted deflation, including red chili, which slightly offset overall inflation.

Pudji said the monthly increase was mainly driven by volatile food prices. “The volatile food component experienced inflation of 2.74% with a contribution of 0.45%,” she said. Core inflation also rose modestly, supported by gold jewelry and cooking oil.

Administered prices edged higher, reflecting increases in fuel, air transport, and intercity transport tariffs. All provinces recorded monthly inflation, with Aceh posting the highest increase at 3.6%, while North Maluku recorded the lowest rise.

On an annual basis, inflation reached 2.92% as the CPI climbed from 106.80 in December 2024 to 109.22 in December 2025. Core inflation accounted for the largest share, driven by gold jewelry, cooking oil, housing rents, education fees, and ground coffee.

Administered prices also contributed to annual inflation, supported by higher water tariffs in multiple regions, fuel prices, and cigarette products. Volatile food prices remained elevated, led by chili, fish, rice, poultry, shallots, and eggs.

Statistics Indonesia said inflation dynamics in December 2025 were influenced by a sustained global gold price rally and weather-related supply disruptions. Heavy rainfall linked to tropical cyclone activity affected food production, particularly in Aceh, North Sumatra, and West Sumatra.
