Recent turbulence in the Middle East has already led Singapore’s energy authorities to warn that prolonged fuel disruptions could affect domestic fuel availability. Washington should read that as more than a local energy story. If a distant crisis can stress Singapore’s system, a high-end Indo-Pacific conflict would do far more. In that scenario, Singapore is not just another exposed small state. It is the Indo-Pacific’s fuel canary.
That is because Singapore combines vulnerability with centrality. It depends on imports for almost all of its energy needs, and about 95 percent of its power generation still runs on natural gas. Yet it is also the world’s largest bunkering port, sold a record 56.77 million tonnes of marine fuel in 2025, and remains a major refining center with about 1.3 million barrels per day of crude refining capacity. If fuel stress shows up first in Singapore, it will not stay in Singapore.
The geography makes the problem worse. The South China Sea is one of the world’s critical energy corridors. In 2023, about 10 billion barrels of petroleum and petroleum products and 6.7 trillion cubic feet of LNG transited those waters. Singapore sits at the hinge between that system and the Strait of Malacca. That is why it should be treated as a strategic barometer: tighter bunker availability, delayed LNG arrivals, or sharper price spikes there would be early signs that the region’s commercial energy architecture, and therefore allied military sustainment, is already under pressure.
This is also a U.S. national security issue in the most direct sense. Singapore’s 1990 memorandum with Washington, renewed in 2019, facilitates U.S. access to Singapore’s air and naval bases and provides logistics support for transiting American personnel, aircraft, and vessels. Singapore has supported rotations of U.S. Littoral Combat Ships and P-8 aircraft, and NAVSEA’s Singapore detachment now supports maintenance and repairs for U.S. Navy ships across the 7th Fleet area outside Japan. Singapore is not adjacent to U.S. posture in Asia. It is woven into it.
What makes Singapore especially useful as a canary is that it has already done more than most to hedge against disruption. The Singapore LNG terminal says it could meet all of the country’s current power-generation needs if required. The Energy Market Authority requires generators to maintain fuel and diesel reserves, has established a Standby LNG Facility, and in 2025 set up Singapore GasCo to centralize procurement, diversify supply, and secure longer-term contracts. Singapore also aims to import around 6 gigawatts of low-carbon electricity by 2035, about one-third of its energy needs, even as natural gas remains a key fuel source as other options scale. In other words, if even Singapore starts straining, Washington should assume the broader system is in worse shape than the headlines suggest.
That is the wider Indo-Pacific problem in miniature: decarbonization is growing, but hydrocarbons will still underpin military mobility, commercial shipping, and grid resilience in any plausible near-term contingency.
What Washington Should Do
First, the United States should treat Singapore-centered fuel stress as warning-and-indications data, not commercial background noise. USINDOPACOM should watch bunker volumes, LNG cargoes, freight and insurance costs, storage drawdowns, repair backlogs, and emergency switching from gas to diesel as leading indicators of theater-wide strain.
Second, Washington should build a more distributed Indo-Pacific fuel architecture. That means pre-arranged storage, refining access, US-flagged tanker lift, and emergency fuel-sharing arrangements across a wider network of allies and commercial partners, so that a shock to Singapore does not become a shock to the campaign.
Third, the United States should treat commercial energy infrastructure as defense infrastructure. Joint planning with Singapore should increasingly cover port recovery, cyber resilience for fuel systems, LNG continuity, and civilian-military coordination for maritime logistics under stress. That would be a far better use of peacetime cooperation than assuming the market will sort it out in crisis.
Finally, Washington should support diversification, not just endurance. It should use peacetime policy to reduce wartime hydrocarbon vulnerability through more resilient contracting, broader fuel options, better US-flagged shipping access, and stronger allied energy coordination before a crisis erupts.
The point is not that Singapore is weak. It is that Singapore is revealing. A state that imports almost all of its energy, runs overwhelmingly on gas, anchors the world’s largest bunkering port, and quietly helps sustain U.S. military presence is one of the clearest indicators of how brittle Indo-Pacific fuel dependence could become in a high-end conflict. Washington should watch Singapore now, not after the warning light turns red.
