BANGKOK – Singapore is considering a trade arrangement that would exchange refined fuel products for dependable Indonesian natural gas. The proposed Singapore-Indonesia gas deal could give Singapore steadier access to energy supply stability while helping it preserve its role as Indonesia’s major fuel supplier.
The idea comes as Jakarta seeks to reduce fuel imports from Singapore and shift some purchases toward the United States and other suppliers. Singapore Minister of State for Transport and Finance Gan Siow Huang has described the arrangement as a possible win-win, but negotiations, approvals, prices, and supply volumes for this crucial gas partnership remain unresolved.
Key Takeaways
- Singapore wants uninterrupted Indonesian natural gas access while continuing to sell refined fuels to Indonesia.
- The proposal is a policy idea, not a signed energy contract.
- Indonesia could gain a reliable gas buyer, fuel access, investment, or better commercial terms.
- Singapore’s earlier gas arrangements show useful infrastructure, but regulatory failures and declining production remain serious risks.
- A final agreement would need confirmed volumes, pricing, contract terms, and Indonesian government approval.
The proposed structure is straightforward. Singapore would continue supplying products such as gasoline, diesel, and jet fuel, while Indonesia would provide a steady flow of natural gas for Singapore’s power stations and industries.
That arrangement would connect two existing trade relationships. Indonesia has long sold pipeline gas to Singapore, while Singapore has refined imported crude and shipped fuel products across the region. A formal exchange could give both sides more certainty, especially when energy prices and international supply routes are volatile.
However, the proposal is still a negotiating position. No completed agreement guarantees that Indonesia will send uninterrupted gas or that Singapore will remain Jakarta’s preferred source of refined fuel.
Gan Siow Huang’s comments point to a possible commercial compromise. Singapore could protect an important export market, and Indonesia could secure a dependable customer for gas production. The final result would depend on whether the governments and companies can agree on terms that fit Indonesia’s domestic energy policy.
Why Singapore needs reliable natural gas imports
Singapore relies heavily on imported natural gas to generate electricity. Gas-fired power plants produce most of the country’s electricity, so interruptions could affect households, manufacturers, data centers, and the wider economy, ultimately driving up every consumer and industrial energy bill.
The country has previously received pipeline gas from Indonesia’s South Sumatra and West Natuna areas. Earlier supply arrangements included gas linked to the Grissik Gas Plant, the Jabung Block, Batam, and the Gajah Baru field. These contracts connected Indonesian production with Singapore’s power market for long periods.
Historical deals matter because gas infrastructure requires large, long-term investments. Pipelines, processing facilities, and power plants cannot be planned around short-term cargoes alone. Singapore therefore has an interest in securing long-term contracts that guarantee a specific volume over many years.
The issue has become more pressing as older fields mature and new projects face delays. Singapore can import liquefied natural gas, but LNG cargoes often carry higher shipping, storage, and market costs. A nearby natural gas service can reduce some of that exposure, provided Indonesia can maintain production, stabilize the necessary gas pressure, and ensure consistent pressure throughout the transmission network.
What Indonesia could gain from supplying gas
Indonesia would receive a dependable buyer close to its producing regions. Singapore’s demand could support upstream projects that might struggle to secure a long-term market elsewhere.
A gas arrangement could also strengthen bilateral energy ties. Indonesia may seek better prices, investment in fields and pipelines, or support for domestic energy projects in return for export commitments. Those benefits could make the trade more attractive than selling gas through shorter contracts.
Still, Jakarta would need to balance export revenue against domestic demand. Indonesia has repeatedly used domestic market obligations to reserve gas for power generation, fertilizer plants, and industrial users. Any promise to Singapore would need to fit those priorities.
The country could also negotiate fuel-related benefits. If Singapore continues supplying selected refined products, Indonesian buyers might gain access to reliable cargoes during refinery outages or periods of strong demand. The deal would have value only if those fuel terms remain competitive with supplies from the United States, the Middle East, or domestic refineries.
Singapore’s refined fuel position faces a new challenge
Refined fuel exports are central to Singapore’s proposal because the country is one of Asia’s largest refining and trading centers. Its location near major shipping lanes, storage terminals, and regional consumers has made Singapore a convenient source for gasoline, diesel, jet fuel, and marine fuels.
Indonesia has long relied on Singapore for a substantial share of refined fuel imports. The relationship supports Indonesian supply, but it also leaves Jakarta exposed to Singapore-based pricing, shipping conditions, and regional market changes. A look at Singapore’s energy trade hub shows how the city-state’s refining and trading role reaches across Southeast Asia, effectively influencing the energy balance of every service area connected to its maritime supply routes.
Jakarta now wants to reduce that dependence. In May 2025, Energy and Mineral Resources Minister Bahlil Lahadalia said Indonesia could redirect as much as 60% of refined fuel imports away from Singapore within about six months. He also said the country could eventually aim for zero imports from Singapore.
The policy shift has links to Indonesia’s trade discussions with the United States. Reuters reported that Jakarta planned to source more energy from the US, including refined fuel and LNG. Indonesia also discussed increasing energy imports from the US by roughly US$10 billion.
Why Jakarta may hesitate to accept gas imports
Indonesia’s fuel policy creates a direct obstacle for any exchange arrangement. The government wants greater control over energy supply, stronger domestic refining, and less reliance on a nearby foreign supplier.
Pertamina was directed in 2025 to stop or reduce fuel imports from Singapore over time. S&P Global Commodity Insights reported that Pertamina excluded Singapore from two second-half 2025 gasoline tenders. Those tenders covered up to 2.65 million barrels per month of 90 RON gasoline and 1.35 million barrels per month of 92 RON gasoline, which must meet strict chemical purity standards where even trace gas particles are monitored during processing.
The change does not mean every fuel shipment from Singapore ended immediately. Reports described a gradual shift, with some purchases moving to the United States and possibly the Middle East. Even so, the direction makes Singapore’s proposed fuel-for-gas arrangement harder to negotiate.
Jakarta may ask Singapore for lower prices, longer payment terms, storage support, or investment in Indonesian refining. Political leaders will also need to show that any continued imports serve national interests rather than preserve an old dependency.
The role of Pertamina, PLN, PGN, and Medco
Several Indonesian companies and agencies would shape a future agreement.
Pertamina would matter because it controls much of Indonesia’s fuel procurement and distribution. Its buying decisions would determine whether Singapore remains an accepted source for particular products.
PLN would influence the gas side through electricity demand. If Indonesian gas is reserved for power generation, PLN’s requirements could limit export volumes. PGN, the country’s gas infrastructure company, could help manage pipeline networks, transportation, and delivery contracts.
SKK Migas oversees Indonesia’s upstream oil and gas sector. Its approval would matter for production plans, export allocations, and field development. Medco Energi is also relevant because it has interests in West Natuna production, including the Mako field.
These parties would need to coordinate with Singapore’s importers, power generators, and gas distributors. A government announcement alone cannot create dependable deliveries. Each company must accept the commercial and operational terms.
Past Singapore-Indonesia gas deals offer both a model and a warning
Singapore and Indonesia have decades of energy cooperation. Early pipeline agreements covered about 2.27 trillion standard cubic feet over 20 years, with an estimated value of roughly US$9 billion. Later arrangements expanded attention to gas from West Natuna and nearby offshore fields.
Those contracts created pipelines, buyer relationships, and experience with cross-border energy trade. They also show why both countries continue to discuss long-term supply. Singapore already has infrastructure designed to receive Indonesian gas, while Indonesia has experience selling to Singapore.
The old agreements don’t guarantee future volumes. Fields decline, domestic consumption rises, and governments revise export rules. A new contract would need to account for those changes rather than rely on past performance. When monitoring long-distance transmission, engineers often reference the ideal gas law to calculate pressure and volume accurately. This relies on stable variables like temperature, while transitions between a gaseous state and liquefied form alter the density of the fuel dramatically.
A recent proposed project shows the risk. Sembcorp Industries and Medco had planned a gas import arrangement involving up to 111 billion British thermal units per day from Indonesia’s Mako gas fields. The supply was expected to support Singapore from 2026 for about 11 years.
Why earlier pipeline and LNG plans fell short
The Sembcorp-Medco agreement was valued at about S$1.9 billion. It was expected to begin in 2024, but Sembcorp terminated the deal after the parties failed to secure required Indonesian regulatory approvals. Reuters reported the cancellation in March 2025.
That outcome is a warning for the proposed exchange. Commercial contracts can collapse when approval rules, domestic allocation policies, or project conditions remain unsettled.
Another example involves a 2017 proposal linked to Keppel Offshore & Marine and Pavilion Energy. The parties studied small-scale LNG distribution involving Indonesia’s PLN, but the arrangement was a nonbinding study. It was not a completed LNG purchase contract, and Indonesian officials denied that Jakarta had agreed to buy LNG from Singapore.
The distinction matters. Announcements, studies, memorandums, and signed supply contracts carry different legal and commercial weight. Readers should not treat every cooperation plan as proof that gas will flow.
Regulation and supply limits could shape the outcome
Indonesia’s approval process is only one barrier. Mature fields may produce less gas over time, while domestic power and industrial users could claim a larger share of output.
Pipeline capacity also matters. Existing lines may need upgrades, compression, or new connections. LNG could fill part of the gap, but importing and regasifying LNG requires different facilities and contracts.
Pricing will be difficult. Singapore wants gas at a cost that supports affordable power and competitive industry. Indonesia wants export revenue that reflects production costs, investment needs, and the value of domestic supply. Both sides would also need rules for price reviews, force majeure events, quality standards, and delivery failures.
A promise of uninterrupted access would require more than a headline. It would need confirmed reserves, upstream investment, transport capacity, backup arrangements, and clear government approvals.
What the proposed energy trade could mean for both countries
Singapore could gain a more predictable gas supply and protect part of its refined fuel business. Continued fuel sales would support refineries, storage operators, traders, and shipping services. Reliable Indonesian gas would also reduce pressure to compete for LNG cargoes during tight global markets, much like consumers locking in a fixed rate plan to avoid market volatility.
Indonesia could gain a nearby gas customer while retaining access to refined products. A negotiated package might bring better pricing, infrastructure investment, or support for local energy needs. It could also preserve cooperation with Singapore while Jakarta develops alternative fuel suppliers, potentially including financial incentives or bill credits for industrial development zones.
The risks are just as clear. Indonesia’s drive for energy self-reliance may conflict with long-term export commitments. Changes in leadership or trade policy could alter the terms. Singapore’s fuel exports may also face competition if Indonesian refineries expand or Jakarta signs larger supply contracts with US and Middle Eastern producers. Furthermore, expanding pipeline networks will require strict operational protocols, such as a mandatory call-before-you-dig procedure, to maintain safety across regional distribution systems.
The wider Southeast Asian market would watch the outcome closely. A stable deal could support regional energy flows, but a failed agreement would reinforce concerns about pipeline reliability and regulatory uncertainty. The Institute for Energy Economics and Financial Analysis has also examined how larger US energy commitments could affect Indonesia’s future import choices.
The concept is commercially attractive because it joins two existing needs. Yet the proposal still depends on formal negotiations, realistic gas volumes, acceptable fuel prices, and regulatory approval in Indonesia.
