The ongoing crisis in the Strait of Hormuz has delivered a sharp lesson in energy fragility, and few places illustrate it more clearly than Singapore. As a premier Asian refining and bunkering hub, Singapore has so far avoided outright shortages thanks to its sophisticated infrastructure and diversified sourcing. Yet the slowdown is real: refineries operating at reduced capacity, sharply higher bunker fuel and jet fuel prices, and growing pressure on regional supply chains. For Australia, this is not a distant problem, it is a direct threat to our own fuel security.
Singapore imports the vast majority of its crude oil from the Middle East. When the Strait of Hormuz effectively closed amid the 2026 Iran conflict, the flow of feedstock slowed dramatically. Refineries on Jurong Island cut throughput, some operating at less than half capacity. While Singapore has drawn on alternative supplies and maintained exports where possible, the price signals are unmistakable: bunker fuel prices have surged more than 40% in key categories, feeding through to higher shipping, aviation, and domestic fuel costs.
This matters deeply for Australia. Singapore is our largest single supplier of refined petroleum products, accounting for roughly half of our petrol imports and a significant share of diesel and jet fuel. In normal times, this arrangement works efficiently: Australia exports LNG to Singapore, while Singapore refines crude and sends back finished fuels. But in a crisis, that interdependence becomes a vulnerability. When Singapore's refineries slow down, Australia feels it quickly at the bowser, in freight costs, and in the broader economy.
The Hormuz disruption has exposed Australia's dangerous reliance on imported refined fuel. With domestic refining capacity long since wound back, we import around 90% of our transport fuels. Panic buying has already emptied some stations during earlier scares, and farm and mining sectors, heavy diesel users, are feeling the pinch. Singapore's ability to keep supplies flowing to us is not guaranteed if the crisis deepens or if the city-state prioritises its own needs and those of larger Asian customers.
This episode should serve as a wake-up call. Energy security is national security. Australia cannot continue pretending that leaving refining to foreign hubs while exporting raw resources is a sustainable strategy. The Singapore slowdown demonstrates how a single chokepoint halfway around the world can ripple straight into Australian price spikes and supply risks.
We need urgent action: rebuilding strategic fuel reserves beyond the current inadequate levels, incentivising domestic refining capacity where viable, diversifying sources aggressively, and treating energy policy as a core sovereignty issue rather than a market convenience. Singapore has shown resilience through its hub status and planning. Australia must now show similar seriousness, before the next disruption leaves us truly stranded.
