The implementation of mandatory B50 biodiesel is widely regarded as a pivotal strategic move to significantly bolster national energy security. This ambitious policy, which mandates a blend of 50% fatty acid methyl ester (FAME) with 50% fossil diesel, is projected to achieve several critical objectives. Foremost among these is the complete cessation of diesel imports, a major step towards reducing Indonesia’s reliance on foreign energy sources. Furthermore, it is expected to generate substantial foreign exchange savings, estimated at approximately IDR 170 trillion annually, providing a significant boost to the national economy.
However, a recent comprehensive study conducted by the NEXT Indonesia Center offers a more nuanced perspective, indicating that the elimination of diesel imports will not automatically translate into a reduction in diesel subsidy expenditure within the State Budget (APBN). This critical finding underscores the necessity of a thorough and holistic evaluation of the fiscal benefits associated with the B50 implementation. Understanding the full financial impact requires a deeper look beyond just import figures.
Herry Gunawan, the esteemed Director of the NEXT Indonesia Center, clearly articulated that the cessation of diesel imports and the reduction of energy subsidies represent two distinct and separate issues. He emphasized that while curtailing diesel imports undeniably strengthens energy resilience and conserves the nation’s foreign exchange reserves, the ultimate magnitude of energy subsidies remains contingent upon a complex interplay of various economic factors. These include the economic price of fuel, prevailing global oil prices, the rupiah exchange rate against major currencies, the total volume of fuel distributed nationwide, and the specific structure of the biodiesel incentive scheme.
“Therefore, stopping imports does not necessarily directly reduce the burden on the State Budget,” Herry Gunawan stated in Jakarta on Sunday, July 26, 2026. His remarks highlight the intricate economic dynamics at play, urging policymakers to consider all contributing elements when assessing the financial viability and overall impact of the B50 program. The fiscal implications extend far beyond the initial savings from reduced imports.
The implementation of B50 arrives at a crucial juncture for Indonesia, as the nation’s oil and gas trade balance has been under persistent pressure for over a decade. Since 2012, Indonesia has consistently failed to record a surplus in its oil and gas trade, signaling a growing structural imbalance. This deficit, which stood at US$5.6 billion in 2012, dramatically escalated to US$19.7 billion by 2025. The trend continued into the current period, with the deficit already reaching US$12.3 billion between January and May 2026, underscoring the urgency of addressing energy import dependencies.
A primary contributor to this widening deficit has been the substantial volume of diesel imports. Over the period spanning 2016 to 2025, Indonesia imported approximately 48 million tons of diesel, representing a staggering value of US$30.3 billion. Even in 2025, after accounting for exports, net diesel imports remained significant, totaling around 4.3 million tons, valued at approximately US$2.8 billion. This persistent reliance on imported diesel has been a drain on the nation’s financial resources and a vulnerability for its energy security.
Concurrently, national diesel consumption has been on a relentless upward trajectory. Data from the Ministry of Energy and Mineral Resources (ESDM) reveals a substantial increase in diesel consumption, rising from 29.9 million kiloliters in 2020 to 39.2 million kiloliters by 2024. This represents an increase of nearly 31 percent in just four years. The vast majority of this consumption comprises BioGasoil, which is diesel blended with FAME in accordance with Indonesia’s mandatory biodiesel policies. However, despite the increasing blend of FAME, the overall surge in consumption means that the demand for the fossil gasoil component within the blend continues to grow, posing challenges for import reduction targets.
According to simulations conducted by the NEXT Indonesia Center, the full implementation of B50 would necessitate approximately 18.8 million kiloliters of FAME per year, assuming national BioGasoil consumption remains at 2024 levels. Currently, the actual utilization of FAME stands at only about 13.2 million kiloliters. This significant disparity implies that Indonesia would require an additional production of approximately 5.6 million kiloliters of FAME, representing an increase of about 42.6 percent compared to present production capacities. This substantial increase highlights the scale of the challenge in meeting the B50 mandate.
“FAME production capacity is the key to the success of the B50 program,” Herry Gunawan emphasized. He further elaborated that “without adequate supply increases, the target of stopping diesel imports will be difficult to achieve sustainably.” His statement underscores the critical importance of scaling up domestic FAME production to match the ambitious targets set by the B50 policy. Without this foundational element, the broader objectives of enhanced national energy resilience and reduced import dependency could be jeopardized.
From a purely mathematical perspective, the additional FAME requirement of 5.6 million kiloliters is even greater than Indonesia’s total diesel import volume in 2024, which was around 4.3 million kiloliters. This presents a compelling opportunity. If BioGasoil consumption remains relatively stable, domestic fossil gasoil production does not change, and the additional FAME supply is entirely utilized to substitute imported diesel, Indonesia stands a strong chance of eliminating its diesel imports. This scenario positions FAME as a direct replacement for foreign oil.
Nevertheless, Herry Gunawan reiterated his earlier caution: stopping imports is not synonymous with saving energy subsidies. He explained that diesel subsidies are specifically designed to bridge the gap between the economic price of fuel and its selling price to the public. Consequently, the value of these subsidies remains susceptible to fluctuations in various factors, including global oil prices, the strength of the rupiah, the total volume of fuel distributed across the country, and the government’s prevailing pricing policies. These elements collectively determine the true cost to the APBN.
Data from the Central Government Financial Report (LKPP) illustrates the historical trend of these expenditures. Between 2016 and 2025, the total spending on diesel oil subsidies amounted to a staggering IDR 173.2 trillion, averaging IDR 17.3 trillion annually. This significant financial outlay highlights that while the primary benefit of B50 implementation is expected to be felt through reduced energy imports and substantial foreign exchange savings, its actual impact on the APBN must be carefully calculated. This calculation must factor in the costs associated with FAME production, the various biodiesel incentives provided to producers, and the operational expenses for blending and distribution.
Herry Gunawan strongly advocates for a broader metric of success for B50, arguing that it should not be solely measured by the cessation of diesel imports. More importantly, he stressed the need to ensure overall cost efficiency across the entire supply chain, guarantee the long-term sustainability of FAME supply, and deliver tangible fiscal benefits to the nation. It is crucial, he warned, to prevent a scenario where the foreign exchange savings achieved through reduced imports are ultimately offset by a heavier burden of incentive costs, thereby negating the intended financial gains.
The NEXT Indonesia Center also highlighted that the anticipated increase in FAME demand, driven by the B50 implementation, must be meticulously matched by the readiness and capacity of the national palm oil industry. This preparedness encompasses several critical aspects: ensuring the consistent availability of raw materials, expanding biodiesel production capacity, developing robust blending infrastructure, and optimizing the entire distribution system. Strengthening these prerequisites is essential to prevent potential supply disruptions or an undesirable surge in production costs, which could undermine the economic viability of the program.
Should all these essential prerequisites be diligently met and effectively managed, the implementation of B50 has the profound potential to serve as a cornerstone in fortifying Indonesia’s national energy security. Simultaneously, it could play a crucial role in significantly improving the nation’s overall trade balance, moving towards a more sustainable and resilient economic future.
