Indonesia’s Subsidized Fuel Buffer Dips to 16 Days as Drivers Abandon Pricier Gasoline

JAKARTA, Investortrust.id — A mass consumer migration away from market-priced gasoline has drawn down Indonesia’s national reserve buffer of subsidized 90-octane Pertalite fuel to between 16 and 18 days, down from historical operating baselines above 20 days.

Coordinating Minister for Downstreaming and Energy Transition Bahlil Lahadalia clarified that the reserve drawdown is confined strictly to Pertalite, while sovereign inventories across all other refined petroleum grades remain well within safe operating margins.

Speaking at a press conference at the Ministry of Energy and Mineral Resources Secretariat in Jakarta on Friday, Oct. 16, 2026, Bahlil attributed the run on supplies to the wide price disparity separating state-subsidized Pertalite from commercial market fuels such as 92-octane Pertamax and 95-octane Pertamax Green. At the pump, subsidized Pertalite remains pegged at Rp 10,000 ($0.55) per liter, compared to commercial Pertamax retailing at Rp 15,950 ($0.88) per liter and Pertamax Green at Rp 19,150 ($1.06) per liter.

"The drawdown in national reserve days to 16–18 days has occurred specifically in RON 90," Bahlil told reporters. "Why did this happen? Because of consumer shifting. Motorists who previously used RON 92 and 95 shifted to 90 because the price difference is substantial."

Maintaining a minimum 20-day fuel buffer has long served as a vital macroeconomic shield for Southeast Asia’s largest economy, which remains vulnerable to volatile maritime supply chains across its archipelago. When global oil volatility widens pump price disparities, consumer demand shifts almost overnight toward state-backed grades, straining refinery blending cycles and testing physical storage limits. While short-term drawdowns remain manageable, lingering bottlenecks risk turning localized distribution snags into broader inflationary headaches if retail forecourts run dry.

Mandatory National Emergency Standards

Bahlil stressed that the current 16-to-18-day reserve buffer satisfies mandatory national emergency standards. The government anticipates replenishing total national inventories back toward 20 days of forward consumption in about a week as refinery blending schedules and supply allocations normalize.

"Under national standards, the reserve level is secure," Bahlil said. "To reach the 20-day benchmark will take us roughly a week. In a week, it will be completed. But sitting at 16 to 18 days does not mean we have fallen beneath the minimum safety threshold."

The minister emphasized that supplies of diesel, as well as higher-octane fuels—including 92, 95, and 98 RON—face no operational constraints. As a result, the national reserve reduction represents a sharp surge in Pertalite retail demand rather than an across-the-board refinery breakdown.

Addressing localized fuel shortages and vehicle lines reported in tourist corridors such as Bali and parts of Southeast Sulawesi, Bahlil maintained that the snarls stem from maritime logistical delays rather than product deficits at domestic refineries. Distribution into Bali relies heavily on sea transport originating from storage terminals in East Java.

"There is no issue with supply. There is no issue at the refineries," Bahlil affirmed. "The issue lies within the distribution corridor, which is precisely why we are deploying additional transport vessels."

To restore regular forecourt deliveries, Bahlil ordered state oil and gas company PT Pertamina to expand its maritime transport fleet immediately, aiming to eliminate island-bound shipping delays and prevent prolonged distribution backlogs across inter-island transit links.
