Singapore is accelerating its push to diversify energy suppliers, expand storage and build new infrastructure after Indonesia unexpectedly announced gas export cuts over the weekend of 24 to 26 October, a move that tests the city-state's carefully engineered supply resilience.
Speaking at Singapore International Energy Week on Monday, 26 October, Minister for Energy, Trade and Industry Tan See Leng said there is no risk of shortages, according to Yahoo News. Indonesia's reductions represent less than 2 per cent of Singapore's daily gas demand.
A calibrated response to resource nationalism
The cuts, framed by Jakarta as necessary to bolster domestic energy supplies, landed days before the region's premier energy conference. Singapore's response has been deliberately low-key: acknowledge the risk, quantify the exposure, and keep investing in alternatives.
“We can keep calm and carry on,” Tan said in his opening address. “Our households and our businesses can be assured that our energy security is always at the top of our minds.”
The minister was blunter about the structural trend behind the episode. “Singapore will not be able to insulate ourselves from global or regional shocks,” he said. “When there is a supply crunch, countries may also prioritise their own domestic needs, and this trend of resource nationalism is particularly concerning.”
What Indonesia says about its commitments
Indonesian Energy and Mineral Resources Minister Bahlil Lahadalia told reporters in Jakarta on Monday that the reduction does not breach contract, arguing that a violation would require cutting more than 10 per cent of piped supplies.
“We are a country that honors contracts and rules,” Lahadalia said. “Don't try to teach Indonesia about commitment to honor and respect contracts.”
For Singapore, the legal question may not be closed. The Straits Times reported that Gas Supply, the national gas importer, may pursue remedies if the cuts are found to breach contractual terms. Singapore has said it expects all parties to honor their commitments.
How exposed is Singapore's power system?
Singapore relies on imported natural gas for almost all of its power generation, a structural fact that has shaped two decades of energy policy. But dependence on Indonesian pipelines has fallen sharply as LNG has taken a larger share.
“About half of our gas is imported as LNG from a global diversified portfolio of sources, such as the US, Africa, the Middle East, and Australia,” Tan said. The country expects to increase LNG import capacity by 50 per cent once a second terminal starts operations by 2030, alongside new power plants and larger fuel stockpiles, Bloomberg reported via BusinessMirror.
The Energy Market Authority has separately confirmed the country holds sufficient supplies, according to The Edge Malaysia, and Singapore requires power generation companies to maintain diesel reserves as a backstop against gas disruptions.
Analysts: manageable now, harder after 2028
Market observers broadly agree the immediate impact is limited. Morgan Stanley said in a 26 October report that higher imports from Malaysia or more spot LNG purchases should offset the shortfall, though at higher gas costs.
The bigger question is the contract renewal cycle. “The bigger test will come when existing export contracts start expiring in 2028,” said Prateek Pandey, head of oil and gas analysis for Asia Pacific at Rystad Energy. “Indonesia has good reason to prioritize its own energy needs.”
Indonesia's overseas gas shipments have been declining in recent years as a growing share of output is directed to domestic consumption. The country ships LNG to China, Japan and South Korea, and pipes gas to Singapore and Malaysia. The current cutbacks should remain manageable for Singapore unless they deepen or production fields are affected, Pandey added.
SLNG ready for disruption
Singapore LNG Corporation, the state-owned terminal operator, said it is prepared to manage disruptions.
“We are always prepared,” Leong Wei Hung, SLNG's chief executive officer, said. “We actually do exercises within the operations just in case something like this happens.”
Tan also announced a non-binding agreement for Saudi Arabia to store crude oil in caverns beneath Jurong Island from the second half of 2027, adding another layer to Singapore's role as a regional energy hub.
The Singapore model meets neighbourhood reality
The episode is a case study in why Singapore's technocratic approach to energy security, diversify early, contract hard, hold reserves, remains the regional benchmark. Jakarta's move is less a breach than a signal: a resource-rich giant increasingly tempted to look inward, with feet of clay where long-term export commitments are concerned.
For ASEAN, the lesson is that resource nationalism does not respect regional solidarity rhetoric. For Singapore, the strategy is already in motion, and the second LNG terminal by 2030 will be the real test of whether the island can keep calm and carry on when the 2028 contract expirations arrive.
Frequently asked questions
How much of Singapore's gas supply did Indonesia cut?
The reductions represent less than 2 per cent of Singapore's total daily gas demand, according to the Energy Market Authority.
Does Singapore face an energy shortage from the cuts?
No. Minister Tan See Leng said on 26 October that there is no risk of shortages, and SLNG said it is operationally prepared for disruptions.
When do Indonesia's gas export contracts to Singapore expire?
Existing export contracts begin expiring in 2028, which Rystad Energy's Prateek Pandey called the bigger test for Singapore's supply security.
