B50 and Fuel Security: How Palm Oil Reduces Indonesia’s Diesel Import Risk

Jakarta — Indonesia is positioning its mandatory B50 biodiesel programme as one tool to reduce diesel import risk when geopolitical tensions disrupt global oil supply routes. Energy and Mineral Resources Minister Bahlil Lahadalia said about 23% of Indonesia’s crude oil supply had previously passed through the Strait of Hormuz, while national fuel demand remains far above domestic oil production.

In a CNBC Indonesia report on 12 October 2026, Bahlil put national fuel consumption at around 1.6 million barrels per day and domestic oil lifting at roughly 600,000 barrels per day. The gap is met through imports of crude oil and petroleum products. B50, however, specifically targets diesel, meaning the programme does not eliminate Indonesia’s reliance on imports across all fuel categories.

B50 is designed to cut diesel imports

B50 blends 50% palm-based biodiesel with 50% fossil diesel. The Ministry of Energy and Mineral Resources (ESDM) said the programme was launched on 9 July 2026 as part of a wider energy-security strategy. According to the ministry, Indonesia consumes about 38 million–40 million kilolitres of diesel a year and had previously imported around 3 million–4 million kilolitres of diesel products.

The government expects the additional biodiesel volume under B50 to replace those imports. Bahlil has said Indonesia would no longer need to import diesel after B50. This remains a government claim and should be assessed against official trade data after the programme has operated at full scale.

Geopolitical risks strengthen the government’s case for greater use of domestic energy resources. Shipping disruptions, conflict in the Middle East, oil-price movements and logistics costs can affect importing countries. By converting palm oil into fatty acid methyl ester for diesel blending, Indonesia aims to reduce part of its exposure to international energy markets.

IDR 170 trillion remains a government projection

President Prabowo Subianto and ESDM have said B50 could save up to IDR 170 trillion, or around US$10 billion, in foreign exchange. The figure is an estimate based largely on reduced diesel imports, not a final audited saving.

ESDM compares the B50 projection with the B40 programme. It estimates B40 foreign-exchange savings at around IDR 133 trillion and B50 savings at IDR 170 trillion. Palm oil demand for the biodiesel programme is projected by ESDM to rise from about 15.2 million tonnes to 16.3 million tonnes.

The ministry also claims that palm oil industry value added could increase from IDR 20.92 trillion to IDR 23.49 trillion, employment could rise from 1.8 million to 2.1 million people, and avoided emissions could increase from 39.66 million tonnes to about 44.46 million tonnes of carbon-dioxide equivalent. All of these figures are government policy projections.

Palm supply and fiscal capacity remain constraints

A study supported by the Plantation Fund Management Agency (BPDP) estimates that B50 could require 17.5 million–18 million tonnes of palm oil, above ESDM’s calculation. The difference shows that actual demand depends on assumptions about diesel consumption, conversion yields, production capacity and realised distribution.

BPDP also identifies several risks: stagnant plantation productivity, limited new land, crop disease, reliance on imported methanol and catalysts, the need for further technical testing, and pressure on biodiesel incentive funding. Its study indicates that higher domestic demand could reduce palm oil exports.

B50 may therefore strengthen diesel security, but it is not a complete solution for Indonesia’s broader fuel requirements. The country still needs higher oil lifting, stronger refineries, additional energy feedstocks and policies that prevent higher palm demand from placing excessive pressure on food, exports, farmers or public finances.
