The Indonesian Economy in Review (September 2026)
The Indonesian economy moved through September 2026 against a backdrop of fiscal consolidation, energy policy recalibration, and persistent currency jitters, even as the government touted record budget figures and ambitious green growth targets. The month’s defining moment came on 29 September when the House of Representatives, under Speaker Puan Maharani, ratified the 2027 State Budget (APBN) into law, setting state expenditure at a record Rp4,106.26 trillion against revenue of Rp3,435.10 trillion, with the fiscal deficit capped at 2.4 per cent of GDP. Finance Minister Suahasil Nazara repeatedly stressed that the budget had been designed with “measured efficiency” and credibility in mind, a message echoed directly from President Prabowo Subianto, who instructed that public welfare, social protection and infrastructure must remain the budget’s organising priorities. The administration’s growth ambition is bold: 6 per cent in 2027, rising towards 8 per cent by the end of the decade, according to Coordinating Minister for Economic Affairs Airlangga Hartarto, who outlined a roadmap built on investment expansion, productivity gains and high-value exports.
A central feature of this fiscal architecture is the evolving division of labour between the Ministry of Finance and the Danantara Investment Management Agency. Prabowo convened his economic ministers specifically to delineate responsibilities, with the state budget tasked with public services and basic infrastructure while Danantara drives large-scale, profit-oriented investment and job creation. Danantara’s Chief Operating Officer clarified that the agency is not yet obliged to remit the much-discussed Rp120 trillion dividend to the treasury, and the fund has also been pushed to ensure continuity of the LRT City project with Adhi Commuter Properti and to press Pertamina Gas to accelerate household gas network expansion, a move aimed at curbing costly LPG imports. Bank Indonesia Governor Destry Damayanti, meanwhile, forecast growth accelerating to between 5.2 and 6 per cent in 2027, contingent on strengthened private investment, while HSBC projected a more modest but still resilient 5.4 per cent for 2026 despite what it called three external shocks. Not everyone shares this optimism: economists from Universitas Gadjah Mada and think tank CORE Indonesia warned that investment growth, which hit Rp1.93 quadrillion in 2025, has failed to translate into proportional formal job creation, with roughly 53,000 layoffs recorded between January and August alone, even as unemployment paradoxically touched a 32-year low.
Energy policy dominated much of the month’s agenda. The government confirmed subsidised Pertalite and Biosolar prices would remain frozen through year-end despite Brent crude surging past US$107 a barrel amid US-Iran tensions over the Strait of Hormuz, a stance reinforced by Deputy Minister Yuliot Tanjung and the Directorate General of Oil and Gas. Energy subsidies for 2027 were trimmed to Rp261.5 trillion, a cut of Rp11.44 trillion, with the savings expected to come from sharper targeting via the National Single Socioeconomic Data system rather than blanket reductions. Full nationwide rollout of B50 biodiesel began on 1 October, though the Palm Oil Farmers Union (SPKS) and sustainability group Madani Berkelanjutan both cautioned that over-reliance on palm oil risks both forest expansion and smallholder exclusion. On the renewables front, the 100 GWp solar programme gathered momentum, with Bakom projecting Rp4.6 trillion in annual budget savings from the first 15 plants and the government eyeing the punitive 114 per cent US tariff on Indonesian solar panels as an unlikely boost to domestic absorption of the country’s 11 GW production capacity. Coal-to-methanol conversion hubs in East Kalimantan and South Sumatra, alongside the Ministry of Investment and Downstreaming’s identification of a US$618.1 billion green downstreaming pipeline across 28 commodities, underscored Jakarta’s intent to climb the value chain from raw smelting towards batteries, BESS and advanced manufacturing. Indonesia also overtook China as the world’s largest processed nickel producer, its global share surging from 1 to 41 per cent, a milestone for the Downstreaming Task Force even as critics urge deeper technological mastery rather than mere volume.
The rupiah’s fragility was a persistent undercurrent. The currency drifted towards the psychologically sensitive Rp18,000 mark, with Bank Indonesia and the government jointly attributing the pressure to a current account deficit that widened to US$12.5 billion in the second quarter, compounded by rising oil import costs. Governor Destry Damayanti and Airlangga Hartarto both called for export-led remedies, while the DPR urged BI to actively strengthen rather than merely stabilise the currency. The Jakarta Composite Index wobbled accordingly, falling as investors digested global headwinds, new IDX regulations and the budget’s implications.
Transport safety emerged as a serious policy flashpoint following the KNKT’s release of its findings on the fatal April collision between the Argo Bromo Anggrek and a commuter train at Bekasi Timur Station, which killed 16 people. Investigators identified six compounding factors, including signalling design flaws, catastrophic communication breakdowns between drivers and controllers, and scratched locomotive windshields impairing signal visibility. The subsequent naming of the train driver as a suspect drew sharp criticism from DPR Commission V chairman Lasarus, who argued that systemic failures, not individual error, were to blame, a view echoed by independent transport experts. PT KAI pledged full cooperation with both KNKT and police, while simultaneously pursuing plans to import second-hand Japanese commuter trains to relieve chronic overcrowding on Jabodetabek lines.
Elsewhere, infrastructure and investment stories painted a mixed picture of ambition and friction. The Rebana Area in West Java, developed with JICA support, recorded Rp131.62 trillion in investment and over 320,000 jobs. The Prosiwangi and Rangkasbitung toll roads advanced towards completion, while the BDx AI data centre project in Jatiluhur was abruptly suspended by West Java Governor Dedi Mulyadi over unresolved permits and fears for agricultural water supplies, highlighting growing tension between digital economy ambitions and resource constraints. Minister Sakti Wahyu Trenggono pressed ahead with a Rp1.2-1.27 trillion transformation of Bali’s Pengambengan fishing port, relocating industrial fishing away from Benoa. Mandalika’s MotoGP continued to be held up as a flagship success, with Erick Thohir citing almost Rp5 trillion in economic impact, even as he conceded Indonesia captures barely 0.5 per cent of the global sport tourism market. Meanwhile, premium rice shortages in modern retail, driven by the withdrawal of disputed fortified rice brands, and a logistics bottleneck at Ketapang-Gilimanuk caused by truck driver protests, served as reminders of how quickly localised frictions can ripple into headline economic anxieties.
Looking ahead, Indonesia enters the final quarter of 2026 with a historically large budget in hand, a renewed energy transition push, and clearer institutional lines between fiscal policy and Danantara-led investment. Yet the test will lie in execution: whether subsidy retargeting protects the vulnerable without stoking inflation, whether downstreaming ambitions translate into formal employment rather than informal churn, and whether the rupiah can find stability as global oil markets remain hostage to Middle East brinkmanship. With a 6 per cent growth target for 2027 now law, the coming months will reveal whether Prabowo’s economic team can convert fiscal scale and green investment pipelines into tangible productivity gains for ordinary Indonesians.
