On 6 April 2026, Finance Minister Purbaya Yudhi Sadewa made a declaration that drew immediate and widespread attention: the prices of subsidised fuels—namely Pertalite petrol and subsidised diesel—would not be raised for the remainder of the 2026 fiscal year. The commitment was delivered before Commission XI of the House of Representatives (Dewan Perwakilan Rakyat/DPR) at a time when global crude oil prices were climbing sharply, driven by an escalation of conflict in the Middle East. The announcement at once raised a fundamental fiscal question: how robust is Indonesia’s State Budget (Anggaran Pendapatan dan Belanja Negara/APBN) in sustaining such a pledge?This essay presents a comprehensive analysis of the APBN 2026’s fiscal endurance under the strain of swelling energy subsidies. The analysis is structured around three principal dimensions: the initial fiscal position that formed the policy’s point of departure; stress-test scenarios constructed on differing oil price assumptions; and the layered budgetary defences that the government has assembled as shock absorbers.An Analysis of Budgetary Resilience Amid Mounting Fuel Subsidy Pressures and Global Oil Price VolatilityThe Initial Fiscal Position and Structural PressuresThe 2026 APBN was designed with total state expenditure of Rp3,786.5 trillion and a revenue target of Rp3,147.7 trillion, yielding a planned deficit of Rp638.8 trillion, equivalent to 2.48 per cent of Gross Domestic Product (GDP). The macro assumption underpinning the entire framework set the Indonesian Crude Price (ICP) at USD 70 per barrel—a figure that proved to be a significant underestimate of actual market conditions.In the original design, the government allocated Rp210.1 trillion for energy subsidies, comprising Rp25.14 trillion for specific-grade fuel subsidies, Rp80.26 trillion for 3-kilogram LPG cylinders, and Rp104.64 trillion for electricity subsidies. When combined with energy compensation payments, the total subsidy and compensation envelope stood at Rp381.3 trillion. The surge in global oil prices to approximately USD 103 per barrel by early April 2026, however, rendered these figures materially inadequate.The most telling indicator of this pressure is the budget’s sensitivity to oil price movements: every USD 1 rise in the crude price per barrel adds up to Rp6.8 trillion to the subsidy burden. With the gap between the APBN assumption (USD 70/bbl) and the actual price (approximately USD 103/bbl) standing at USD 33 per barrel, the potential additional exposure across a full fiscal year exceeds Rp200 trillion—a pressure that is no longer marginal in character, but structural.Scenario Analysis: Stress-Testing the APBNThe Ministry of Finance has prepared a series of stress-test scenarios reflecting differing oil price trajectories throughout the year. These scenarios provide a clear picture of the critical thresholds at which the APBN’s resilience begins to fracture.Optimistic scenario: USD 86 per barrelAt an average oil price of USD 86 per barrel, with the rupiah exchange rate at Rp17,000 per US dollar, projections indicate that the APBN deficit would reach 3.18 per cent of GDP. This already breaches the legal ceiling stipulated in State Finance Law No. 17 of 2003, which caps the deficit at 3 per cent of GDP. Paradoxically, even the scenario labelled ‘optimistic’ would place the government outside its own statutory fiscal corridor. Exceeding this threshold requires parliamentary approval, carrying significant implications for Indonesia’s fiscal reputation in the eyes of international investors and rating agencies.Moderate scenario: USD 97 per barrelAt USD 97 per barrel with the rupiah at Rp17,300 per US dollar, the deficit is projected to widen to 3.53 per cent of GDP. Significantly, Coordinating Minister for Economic Affairs Airlangga Hartarto stated explicitly that subsidised fuel prices could only be maintained throughout 2026 as long as the average oil price did not exceed USD 97 per barrel. This means the moderate scenario itself effectively represents the upper boundary of the government’s commitment without additional fiscal intervention.Purbaya’s commitment ceiling: USD 100 per barrel annual averageThis is the scenario in which the government has formally pledged to hold subsidised fuel prices. Assuming an annual average of USD 100 per barrel — which implies some months above and some below that figure — the government is targeting a deficit of approximately 2.92 per cent of GDP. This outcome is achievable only if every layer of the budgetary defence mechanism (discussed in Section IV) operates fully and simultaneously. In other words, there is no margin for any single mitigating mechanism to fall short of its target.Pessimistic and tail-risk scenarios: USD 115–150 per barrelAt USD 115 per barrel with the rupiah at Rp17,500 per US dollar, the deficit is projected to reach 4.06 per cent of GDP, equivalent to approximately Rp1,004 trillion. At this level, the government’s debt ratio could approach or exceed 45 per cent of GDP, narrowing monetary policy manoeuvre space and substantially increasing debt servicing costs. At the extreme tail of USD 150 per barrel — a scenario Purbaya himself has acknowledged—the Saldo Anggaran Lebih (SAL) fiscal reserve becomes the only remaining instrument of defence. Under such conditions, the APBN would no longer be able to stand on its own structural footing.Six Layers of Fiscal DefenceThe government is not relying solely on the existing budget posture. Its fiscal defence strategy is deployed in layers, with each serving as a buffer before the next is activated.The first layer is the energy subsidy allocation within the APBN itself (Rp210.1 trillion), constituting the primary line of defence. The second is expenditure efficiency across ministries and government agencies, implemented in stages by trimming budget lines deemed less of a priority. The third layer draws on windfall gains from Non-Tax State Revenue (PNBP) in the energy and mineral resources sector: paradoxically, elevated oil and coal prices simultaneously boost state revenues, a portion of which can be redirected to offset the very subsidy burden they create. The fourth layer involves PT Pertamina acting as a temporary absorber, whereby the state-owned enterprise initially bears the price differential before receiving government compensation of approximately 70 per cent per month on a rolling basis.The fifth layer is the B50 biodiesel programme, scheduled to take effect on 1 July 2026. By reducing dependence on fossil-based fuel by approximately 4 million kilolitres, the programme is projected to cut the energy subsidy burden by up to Rp48 trillion — a saving of considerable significance. The sixth and final layer is the SAL reserve of Rp420 trillion, held at Bank Indonesia (Rp120 trillion) and a consortium of state-owned banks or Himbara (Rp300 trillion). The SAL represents an accumulation of unspent budget surpluses from previous fiscal years, and Purbaya has stated unequivocally that this instrument will only be activated under genuinely pressing circumstances, and only with the consent of Commission XI of the DPR.Critical Pressure Points and Medium-Term RisksWhilst the APBN can technically sustain the fuel price freeze through end-2026 under the government’s central commitment scenario (USD 100/bbl annual average), several risks demand careful scrutiny.First, exchange rate risk functions as an amplifier. Every Rp100 depreciation in the rupiah per US dollar does increase state revenues by approximately Rp5.3 trillion, but it simultaneously raises state expenditure by Rp6.1 trillion — yielding a net deficit-widening effect. Should rupiah depreciation coincide with a surge in oil prices, the cumulative impact would be considerably more severe than the arithmetical sum of either factor in isolation.Secondly, there is a high degree of dependence on the simultaneous success of all defensive layers. The government’s target of a 2.92 per cent deficit at USD 100/bbl is only realisable if ministry expenditure efficiency, PNBP windfall revenues, the B50 programme, and Pertamina’s absorptive capacity all perform in accordance with their respective targets. Failure in any single one of these mechanisms would push the deficit dangerously close to the legal 3 per cent ceiling.Thirdly, the fiscal position as at end-March 2026 already shows a deficit of Rp240.1 trillion, or 0.93 per cent of GDP, within the first three months of the fiscal year alone. Should this pace of expenditure continue — and subsidy pressures tend to intensify rather than ease as oil prices rise — the annual deficit target will come under increasing strain. Tax revenue growth of 20.7 per cent year-on-year provides a degree of relief, but the 3 per cent decline in PNBP, attributable to the rerouting of state-owned enterprise dividends to the Danantara investment vehicle, is a signal that warrants vigilance.Fourthly, under the pessimistic scenario (USD 115/bbl), even the Rp420 trillion SAL would prove insufficient to bridge the deficit gap on its own. At a deficit level of 4.06 per cent of GDP (Rp1,004 trillion), the gap between the actual deficit and a fiscally sustainable position exceeds what the SAL can patch without fundamentally compromising its function as a long-term national reserve.ConclusionIndonesia’s 2026 APBN finds itself in a position that is technically manageable, yet genuinely precarious. The government’s commitment not to raise subsidised fuel prices is a pledge that can be honoured through end-2026 — but only under one very specific and demanding set of conditions: that the average annual crude oil price does not exceed USD 100 per barrel, that the rupiah exchange rate remains relatively stable, that every mitigation programme performs as designed, and that no additional external shocks arrive to further erode the fiscal position.Put differently, the APBN 2026 possesses sufficient resilience to complete this fiscal year without reneging on its subsidy commitment, but with virtually no margin for error. The Rp420 trillion SAL is a formidable last line of defence — but it is not an inexhaustible one. In the medium term, absent a more targeted subsidy reform and a broadened national revenue base, the policy of suppressing fuel prices in an era of geopolitical instability will continue to place Indonesia’s public finances on an ever-narrowing ledge each time global oil markets are thrown into turmoil.The most important lesson of this analysis is not whether the APBN will hold—but rather the price that must be paid for that resilience, and whether that price is commensurate with the social protection it affords to the population it is designed to serve.

Layers of fiscal defence — stacked buffers
Layers are deployed sequentially. The government has stated SAL will only be activated if Layers 1–5 prove insufficient. Each layer narrows the fiscal gap, reducing dependence on the reserve.
