This Week in the Indonesian Economy (22-28 May 2026)

The week of 22 to 28 May 2026 will be remembered as one of the most turbulent in recent memory for the Indonesian economy, with global geopolitical shocks colliding with domestic vulnerabilities to produce a picture of both resilience and acute strain. At the centre of the storm was the escalating US-Iran military confrontation in the Strait of Hormuz, which sent global oil prices surging toward USD 96 per barrel, battered emerging market currencies, and forced policymakers in Jakarta into a series of rapid and sometimes improvised responses.

The Rupiah Under Siege

The most visible sign of distress was the Indonesian rupiah, which weakened to historic lows throughout the week, trading as low as Rp 17,873 in offshore markets and nearing the psychologically significant Rp 18,000 level onshore. The currency’s decline was not merely a reflection of dollar strength; economists were quick to point out that the rupiah had depreciated against ten Asian currencies this year, including the Singapore dollar and the Malaysian ringgit, exposing deeper domestic vulnerabilities. Bank Indonesia’s widening current account deficit – reported at 1.1 per cent of GDP in the latest quarter, up from 0.7 per cent – compounded the pressure, as foreign currency outflows exceeded inflows from exports and services.

Bank Indonesia’s 50-basis-point rate hike to 5.25 per cent, announced earlier in May, provided limited relief. Trimegah Securities’ chief economist Fakhrul Fulvian argued the currency should trade far closer to Rp 16,800-17,000 given Indonesia’s economic fundamentals, but stressed that Bank Indonesia cannot stabilise the rupiah alone without coordinated fiscal support. Senior economist Wijayanto Samirin delivered a sterner warning, cautioning that the real danger lies not in import costs or debt service but in eroded market confidence – evoking the psychological spiral of 1998, though most analysts were careful to note that today’s fundamentals remain structurally sounder. Finance Minister Purbaya Yudhi Sadewa dismissed the weakness as illogical given Indonesia’s 5.61 per cent GDP growth in the first quarter of 2026 – the strongest expansion since the third quarter of 2022 – but international rating agencies expressed concern over the controversial establishment of PT Danantara Sumberdaya Indonesia (DSI), the new state-owned export entity, warning of potential trade disruptions and capital outflows.

Global Energy Shocks and Their Domestic Fallout

The US-Iran confrontation, which entered its third month during the week, saw American forces launch multiple strikes near the Strait of Hormuz, downing Iranian drones and targeting missile launchers and mine-laying vessels. Iran retaliated by striking a US airbase in Kuwait, prompting Kuwait to activate its air defences. The IRGC reported that it was supervising vessel transits through the strait, and the Netherlands deployed a minesweeping vessel to a NATO task force with potential Hormuz deployment. Oil prices swung wildly – at times surpassing USD 96 a barrel before dipping on news of diplomatic overtures, only to surge again – while President Trump threatened to attack Oman if it attempted to control the waterway.

For Indonesia, the consequences were direct and severe. As a net oil importer, the country faces mounting fuel subsidy costs and imported inflation. Pertamina’s subsidiary PHE temporarily halted production at Iraq’s West Qurna field, losing up to 100,000 barrels per day and raising concerns about the company’s full-year lifting targets. The government extended its work-from-home policy for civil servants by two months – citing a near 9 per cent reduction in Pertalite consumption in April – and the Coordinating Ministry for Economic Affairs urged regional governments to strengthen local resource-based economies. Coordinating Minister Airlangga Hartarto also confirmed the Rp 7.8 trillion second-quarter stimulus package, which features transport discounts, a 1.5 per cent final income tax rate for authors, and expanded vocational training programmes.

Sumatra’s Blackout and the Grid’s Fragility

The week also laid bare the fragility of Indonesia’s electricity infrastructure. On the evening of 22 May, a fault on the 275 kV Muara Bungo-Sungai Rumbai transmission line in Jambi – attributed to severe weather – triggered a cascading blackout across Jambi, West Sumatra, Riau, North Sumatra and Aceh, affecting roughly 13.1 million customers and disrupting telecom networks operated by Telkomsel, XL Smart and Indosat Ooredoo Hutchison. PLN’s president director Darmawan Prasodjo personally oversaw the recovery effort, which restored power to 8.35 million customers by the morning of 23 May, though full normalisation took several days.

The incident drew immediate comparisons to the 2019 Java-Bali blackout and prompted calls for urgent action. Public policy analyst Agus Pambagio warned that delays in the 500 kV SUTET transmission projects, combined with land acquisition bottlenecks and cross-regional permitting challenges, risked worsening supply as demand grew. Puskepi’s Sofyano Zakaria urged development of a stronger Sumatran power backbone, citing international precedents from Australia and the United Kingdom. North Sumatra Governor Bobby Nasution demanded PLN prevent a recurrence ahead of the AFF U-19 tournament, while industry experts warned the outage was already damaging Indonesia’s data centre investment pitch, with concerns that investors could redirect commitments to Malaysia or Thailand. Consumer rights group YLKI insisted PLN must provide automatic compensation without complex claims processes, citing energy ministry regulations.

Rare Earth Smuggling and Illegal Mining

In the Riau Islands, the Forest Area Clearance Task Force and the Indonesian Navy thwarted what authorities described as a trillion-rupiah illegal mineral smuggling operation, seizing 390 tonnes of rare earth elements and radioactive materials at Batam’s Kodaeral IV Terminal. Investigators from the Attorney General’s Office are examining potential corruption, abuse of power and document forgery. Separately, the Ministry of Forestry named four Chinese nationals as suspects in an illegal gold mining case in Nabire, Central Papua, where nearly 200 hectares of forest had been cleared and ten units of heavy machinery seized. The suspects face up to fifteen years’ imprisonment under the Forest Destruction Prevention Act. The Ministry of Energy and Mineral Resources meanwhile revealed it was probing seven illegal mining operations across Kalimantan, Java, Sumatra and Maluku, with potential state losses of Rp 857.55 billion.

Holiday Traffic, Domestic Consumption and Tourism

Against this turbulent backdrop, the Eid al-Adha and Pancasila Day long weekend provided a vivid reminder of Indonesia’s domestic economic engine. Jasa Marga recorded 321,039 vehicles departing Jabotabek – a 19.62 per cent rise from normal – while traffic on the Trans-Java toll roads surged by as much as 94.9 per cent at the Cikampek Utama gate. KAI sold more than 911,000 tickets for the holiday period, with the Gambir-Yogyakarta route the most popular, and the Compartment Suite service posting a 79 per cent year-on-year rise in passengers for the first four months of 2026. Ragunan Zoo welcomed 16,000 visitors on the joint-leave day alone, while InJourney Airports forecast three million passengers across its 37 airports during the holiday period.

Tourism was not without its shadows. The fatal collapse of a suspension bridge at Cunca Wulang Waterfall in Labuan Bajo, which killed two Austrian tourists, prompted the West Manggarai regent to order a full safety audit of all sites in the region and reignited concerns about infrastructure maintenance at what is designated a national super priority destination. Meanwhile, heavy traffic at Tanjung Priok forced Jakarta Governor Pramono Anung to issue a public apology after container handling operations at Depo Budi Dharma caused extensive congestion in the Priok-Cilincing corridor, underscoring persistent weaknesses in the capital’s logistics infrastructure.

Investment, Energy Transition and Digital Economy

Several significant investment announcements punctuated the week. Indonesia’s first wind energy-to-electricity conversion project in Batam, led by PT McDermott Indonesia and backed by Bappenas, secured a USD 240 million investment commitment projected to create 7,000 jobs. HSBC China unveiled a USD 4 billion credit facility to support Chinese clean energy firms expanding into Indonesia, aligned with the country’s estimated USD 97 billion clean energy investment needs by 2030. Danantara Investment Management reported 85 entities had qualified for the second phase of the Waste-to-Energy programme – a 254 per cent rise from the first round – while PHE, PGN and Pupuk Indonesia signed a Joint Study Agreement to develop Carbon Capture and Storage technology for low-carbon ammonia production. South Korea introduced a temporary visa waiver for Indonesian tourist groups, a modest but welcome signal for the tourism sector’s recovery.

Outlook

The weeks ahead will test Jakarta’s capacity to hold these disparate pressures together. The trajectory of US-Iran negotiations will determine whether oil prices ease or push toward the USD 100 mark that several analysts warned could become a sustained new floor, with damaging consequences for Indonesia’s subsidy bill and current account. The rupiah’s stability hinges on whether the government can deliver the fiscal-monetary policy coordination that economists have repeatedly demanded, and whether the controversy surrounding PT Danantara Sumberdaya Indonesia can be managed without further unsettling international investors. On the structural side, the Sumatra blackout has placed energy grid reform firmly back on the national agenda, while the Batam wind project and the HSBC credit facility suggest that the energy transition pipeline is deepening – provided governance and implementation keep pace. Indonesia’s GDP growth fundamentals remain genuinely solid, but turning that macro headline into durable household prosperity will require the government to translate stimulus announcements into ground-level delivery with a speed and quality that the People’s Schools project, still only 63 per cent complete, has yet to demonstrate.
