Indonesia began cutting natural gas exports to Singapore on Saturday, October 24, reducing pipeline supplies by 31 billion British thermal units per day (BBTUD), the head of upstream regulator SKK Migas, Djoko Siswanto, said on Friday evening, according to Indonesia's state news agency Antara, reported by The Straits Times and other regional outlets.

The reduction is split between the two pipeline sources that feed Singapore directly: 15 BBTUD from the Natuna fields and 16 BBTUD from Sumatra, with the Sumatra cut coming from the Jambi Merang field, Djoko said. He stressed that no other country is affected, because the pipelines in question go only to Singapore.

In Singapore, importer Gas Supply — one of the city-state's largest gas suppliers, wholly owned by Temasek — told The Straits Times on Saturday that its deliveries to customers had been affected by 'temporary reductions' in supply from its Indonesian supplier, and that it was in direct communication with affected customers while engaging closely with its upstream supplier to manage the situation.

The volumes are small against Singapore's total demand — energy analyst David Broadstock estimated the cut at about 2.25 percent of Singapore's gas usage, citing December 2025 data — but the exposure matters because natural gas generates about 95 percent of Singapore's electricity, according to figures cited by Reuters and The Straits Times.

Jakarta says the gas is being redirected to domestic electricity generation and industry. SKK Migas linked the move to safeguarding domestic supply, and it follows remarks this week by Energy and Mineral Resources Minister Bahlil Lahadalia, who said Indonesia — which uses about 70 percent of its gas production at home and exports about 30 percent — would review export allocations and could consider not renewing gas export arrangements with neighbouring countries, citing national energy security and the needs of its downstream petrochemical sector.

Indonesia had already agreed in 2022 to extend gas supplies to Singapore until 2028 at lower volumes than under the previous contract, and a gas-swap arrangement signed in May 2025 was designed to let more Sumatra gas serve Indonesian users. Neither SKK Migas nor the Singapore authorities have said publicly how long the current reduction will last.
