Indonesia Cuts Natural Gas Exports to Singapore

Indonesia began reducing natural gas exports to Singapore by 31 billion British thermal units per day (BBTUD) on October 24, 2026. The reduction follows a shift in government policy as Indonesia moves to prioritize domestic energy security amid global geopolitical uncertainties.

As of October 24, 2026, the cuts affect gas supplied via pipelines originating from Natuna and Sumatra. The move was confirmed by SKK Migas, Indonesia's upstream oil and gas regulator, which noted that the reduction specifically impacts pipelines connected to the city-state.

Why it is trending now

The trend is driven by official announcements from the Indonesian government regarding a potential shift in long-term export arrangements. Earlier in the week, Indonesia’s Coordinating Minister for Downstreaming and Energy Transition, Bahlil Lahadalia, suggested the country might stop renewing gas export contracts with neighbouring nations. This policy shift is framed by Jakarta as a necessity for national energy security.

Key facts

• Indonesia’s upstream regulator, SKK Migas, confirmed the 31 BBTUD reduction commenced on October 24, 2026, according to The Straits Times.
• The cuts specifically target gas from the Jambi Merang field in Sumatra, as reported by The Straits Times.
• Singapore GasCo CEO Alan Heng stated on October 23 that the company is focused on building a diversified and flexible portfolio to ensure energy security, according to The Business Times.
• Singapore currently uses natural gas to generate 95 per cent of its total electricity, as noted by The Business Times.

Why this is trending in Singapore

This development is of high interest in Singapore because the city-state is heavily dependent on natural gas to power its grid. With Indonesia being a key supplier, any adjustment to export volumes directly impacts discussions regarding Singapore's energy resilience and the stability of electricity prices.

Background and context

Indonesia has historically been one of Singapore's largest natural gas suppliers. In 2025 alone, Singapore received 3.22 million tonnes of natural gas from Indonesia. The current situation follows recent comments from Indonesian officials indicating a tougher stance on energy exports, particularly toward countries perceived as not respecting Indonesia’s interests.

What happens next

It is not confirmed how long these supply reductions will last or if further cuts are scheduled. Singapore GasCo has indicated it will continue working with regional partners to maintain energy resilience, though analysts cited by The Business Times have warned that supply curbs could influence power prices in the city-state.
