This Week in the Indonesian Economy (11-17 Sep 2026)

Indonesia’s economic week was dominated by a leadership transition at the Ministry of Finance, a global energy shock that tested the government’s fiscal nerve, and a maritime tragedy that continues to expose weaknesses in the country’s transport safety regime. Layered on top of these were significant infrastructure milestones in Jakarta, an escalating push to formalise state control over natural resource exports, and mounting anxiety over fuel distribution that briefly turned into open queues in Makassar.

The most consequential development was the swearing-in of Suahasil Nazara as Finance Minister, replacing Purbaya Yudhi Sadewa in the third such change under President Prabowo Subianto. Commission XI chairman Mukhamad Misbakhun expressed confidence in Nazara’s fiscal credentials, while business groups including Kadin, Apindo and Hipmi welcomed the move as a signal of continuity, urging him to preserve the state budget’s credibility while unblocking investment bottlenecks. Economists were less sanguine about the environment he inherits. Analysts at CORE Indonesia and Trimegah Sekuritas flagged hidden fiscal liabilities, from energy compensation debts to potential cooperative loan guarantees, while others noted the 2027 draft budget’s assumptions look increasingly detached from a world of a strengthening dollar and Brent crude flirting with $108 a barrel. Nazara has pledged to hold the deficit below 3% of GDP even as DPD RI pushes for regional transfers to rise to Rp780.22 trillion and some lawmakers in Commission XI argue the deficit ceiling itself should be revisited to escape the middle-income trap. The rupiah’s slide to around Rp17,700 against the dollar underscored the stakes.

That currency pressure was compounded by a genuine external shock: drone attacks on Saudi Arabia’s East-West Pipeline and Houthi advances along the Red Sea and Bab el-Mandeb corridor sent Brent crude surging past $108 and threatened up to 4% of global oil supply. Energy Minister Bahlil Lahadalia has been the government’s most visible crisis manager throughout the week, repeatedly asserting that national crude supplies remain secure, including through government-to-government imports from Russia, while pledging that subsidised Pertalite and Biosolar prices will not rise before 31 December 2026. This promise carries a real fiscal cost given Indonesia imports roughly a million barrels a day against domestic production of around 600,000, but economists broadly endorsed holding the line to protect purchasing power and contain inflation. President Prabowo has meanwhile pushed an ambitious energy sovereignty agenda through the National Energy Council, chairing sessions on E20 and E50 ethanol blending, B50 biodiesel, and instructing the preparation of two million hectares of sugarcane land. A new Special Oil and Gas Business Entity, BUK Migas, is being designed to report directly to the President and replace SKK Migas, part of a broader Oil and Gas Bill now with the executive branch.

The energy volatility had immediate domestic consequences. Long queues for subsidised fuel in Makassar dominated headlines for days, with Bahlil attributing the shortage to consumers switching from non-subsidised to subsidised fuel and to hoarding via modified vehicle tanks capable of carrying a tonne of fuel. Pertamina Patra Niaga apologised repeatedly and extended operating hours, while the ministry signalled new regulations to stop wealthier motorists exploiting subsidised fuel. El Niño-driven drought compounded matters by cutting hydropower output in Sulawesi and Kalimantan, prompting Bahlil to convene PLN on contingency generation.

Maritime safety returned to the forefront following the sinking of KM Virgo Transport 8 in the Java Sea near the Masalembu Islands, with 129 of 243 passengers still missing by week’s end. Basarnas deployed the KRI Canopus and prepared a salvage operation with experts from Hong Kong and the United States, while the Ministry of Transport launched an investigation into the vessel’s import legality, given the ferry was reportedly imported despite exceeding age limits. Naval Kopaska divers and ITS hydrodynamics experts, including Professor I Ketut Aria Pria Utama, have raised pointed questions about whether a 39-year-old Japanese-built ferry designed for calm inland waters was ever suited to Indonesia’s open seas. The tragedy has galvanised parliamentary calls for stricter seaworthiness inspections and a nationwide fleet audit, alongside Transport Minister Dudy Purwagandhi’s directive that safety inspections take precedence over commercial schedules.

Jakarta’s infrastructure story was more celebratory. President Prabowo personally inaugurated the Kelapa Gading-Manggarai LRT extension, a Rp12.1 trillion, 12.2-kilometre project expected to carry 80,000 passengers daily, complete with an eight-day promotional fare of just Rp8. The President publicly praised Governor Pramono Anung despite their differing party affiliations and instructed Danantara to help finance further extensions to Dukuh Atas, JIS and the Whoosh Halim station, with construction slated from January 2027. This sits alongside Prabowo’s broader “Indonesia ASRI” green city agenda and confirmation that Jakarta’s investment realisation reached Rp173.6 trillion by mid-2026, some 17.2% of the national total.

Elsewhere, the drive to tighten control over natural resource exports gathered pace, with Prabowo asserting that Indonesia has lost roughly Rp15,000 trillion over 34 years to under-invoicing and transfer pricing, and unveiling plans to expand DSI’s single-window export monitoring from 1 January 2027. MIND ID’s leadership faced tough parliamentary questioning over private sector dominance of resource rents, while PT Timah’s profits surged following Presidential Regulation 79/2026 on tin mining governance in Bangka Belitung. The Bogor Raya 1 Waste-to-Energy plant broke ground under Danantara, backed by Rp2.8 trillion investment and a power purchase agreement with PLN, part of Coordinating Minister Zulkifli Hasan’s push to cut 160 regulations down to three to accelerate similar projects nationwide.

Looking ahead, Suahasil Nazara’s early tenure will be judged on whether he can keep the budget deficit credible while global oil prices, a fragile rupiah and rising debt service costs squeeze fiscal space simultaneously. The Makassar fuel queues and El Niño’s grip on hydropower suggest energy security will remain a live domestic issue well into the final quarter, even as Bahlil’s Russia and Africa diversification strategy takes shape. The KM Virgo investigation, once concluded by the KNKT, could reshape vessel age regulations and force a reckoning with Indonesia’s ageing inter-island fleet. Meanwhile, Jakarta’s LRT expansion, the Bogor waste-to-energy rollout and the DSI export monitoring regime all point to a government leaning heavily on Danantara and state-directed investment vehicles to deliver visible wins ahead of the harder structural reforms, tax ratio improvement, deindustrialisation risk, and genuine downstreaming value-add, that economists insist remain unfinished business.
