Australia races to solve fuel crisis as Iran blockade threatens supply chains

Australian headlines are calling it a fuel crisis. Energy Minister Chris Bowen insists it's a demand problem, not a supply problem. Shadow Industry Minister Andrew Hastie says the government has no plan. All three claims contain some truth, but none of them capture what's actually happening in the refineries of Singapore, South Korea and Malaysia — the places that determine whether Australia runs out of petrol in May or keeps the pumps flowing through winter.

Prime Minister Anthony Albanese will convene National Cabinet tomorrow from Hobart to propose appointing a fuel supply chain coordinator. The move follows two weeks of localized shortages, panic buying and petrol prices pushing past $2.30 per litre in most state capitals. Government sources say the coordinator will act as a bridge between federal bureaucrats and the private sector, with states and territories asked to nominate their own point person for ongoing communication.

The coordination sounds sensible. Whether it addresses the underlying problem is another question.

What the blockade actually means

Iran closed the Strait of Hormuz on March 4 in retaliation for joint US and Israeli airstrikes that began on February 28. The closure cut off roughly 20 million barrels per day of oil — about one-fifth of global supply — and took another 6 million barrels per day of Middle East production offline. Brent crude oil prices surpassed $100 per barrel on March 8 for the first time in four years, peaking at $126 per barrel before retreating slightly as traders priced in coordinated reserve releases from IEA member countries.

Australia imports very little fuel directly from the Middle East. In January 2026, just 118.2 million litres of oil came from the United Arab Emirates, compared to more than 5,600 million litres from Asian nations — primarily South Korea, Singapore, Malaysia, Taiwan and Brunei. The Australian government has repeatedly emphasized this point. Energy Minister Bowen told journalists on Tuesday that every ship expected to arrive has arrived, and fuel companies have told him they expect deliveries to continue "well into April."

The framing is accurate but incomplete. Australia may not import much from the Gulf states, but Singapore, Malaysia and South Korea certainly do. Those refineries import crude oil from Iran, Saudi Arabia, Iraq and the UAE, process it, and export refined products — including petrol and diesel — to Australia. When the Strait of Hormuz closes, Asian refineries lose access to roughly 40% of their crude feedstock. They can substitute other sources, but not instantly and not at the same price.

What's happening in Asian refineries

Singapore's refining sector, which supplies roughly 30% of Australia's fuel imports, processes about 1.5 million barrels per day of crude. Before the Hormuz closure, approximately 600,000 barrels per day came from Saudi Arabia, the UAE and Iraq. Those supplies are now offline or severely disrupted. Singapore refineries are working through existing crude inventories and have started booking alternative supplies from the United States, West Africa and Latin America, but those cargoes take longer to arrive and cost more.

South Korea faces a similar problem at larger scale. Korean refineries process about 3 million barrels per day and historically sourced 40% of that from the Middle East. SK Energy and S-Oil have both confirmed they are securing replacement crude from Russia, Kazakhstan and the United States, but the logistics are complicated. A tanker from the US Gulf Coast to Ulsan takes roughly 35 days via the Cape of Good Hope, compared to 18 days from the Persian Gulf via Hormuz.

Malaysia's Petronas operates two major refineries at Melaka and Port Dickson with combined capacity of about 370,000 barrels per day. Both facilities historically relied on crude from Saudi Arabia and the UAE. Petronas has not publicly detailed its contingency plans, but industry sources in Kuala Lumpur indicate the company is negotiating spot purchases from Oman and looking at Russian Urals crude as a backstop.

A report published by Caixin Global on March 7 — not yet widely circulated in English-language financial media — detailed how Chinese state-owned refineries including Sinopec and PetroChina pulled forward non-Middle Eastern crude bookings in late February, anticipating a possible closure of Hormuz. Those purchases locked up available West African and Latin American supplies before Singapore and South Korean buyers entered the market, effectively pre-empting some of the spot market liquidity that refineries in other countries were counting on.

China's export ban changes the equation

On March 15, China's National Development and Reform Commission banned all exports of petrol and diesel indefinitely, citing domestic energy security. The ban removes roughly 200,000 barrels per day of refined product from the regional export market — not a massive volume in absolute terms, but enough to tighten supply margins across Asia-Pacific.

Australia does not import significant volumes of fuel from China under normal conditions, but other countries in the region do. When those buyers lose access to Chinese supply, they compete more aggressively for cargoes from Singapore, South Korea and Malaysia — the same refineries Australia relies on. Reuters reported on March 16 that ExxonMobil Australia is preparing contingency plans to source fuel from the United States if Asian suppliers prioritize domestic or regional customers over Australian contracts.

Shipping fuel from the US Gulf Coast to Australia adds roughly two weeks of transit time and significantly higher freight costs compared to Singapore. Traders estimate the total delivered cost of a cargo from Houston to Melbourne could run 15-20% higher than the equivalent cargo from Singapore, even before accounting for potential insurance premiums related to longer voyages.

Australia's reserve position

Australia currently holds 37 days of petrol reserves and 30 days of diesel, according to the most recent data from the Department of Climate Change, Energy, the Environment and Water. Both figures fall well short of the International Energy Agency's 90-day stockholding obligation, a benchmark Australia has never met despite repeated commitments to do so.

The government released approximately six days' worth of petrol and five days' worth of diesel from those reserves as part of a coordinated IEA response to the Hormuz closure. The release was designed to augment ongoing commercial supply, not replace it. Energy Minister Bowen emphasized that the reserves are a buffer, not a standalone solution.

The government also temporarily lowered fuel quality standards for 60 days, allowing domestic refineries to redirect some production previously earmarked for export into the Australian market. The measure is expected to add roughly 100 million litres of petrol per month — equivalent to about two days' worth of national consumption — but the additional supply flows through over weeks, not immediately.

These measures buy time. Whether they buy enough time depends on what happens in the Middle East over the next four to six weeks.

The panic buying problem

Fuel tankers continue arriving in Australian ports on schedule. NRMA spokesman Peter Khoury confirmed that 18 tankers arrived last week and another 33 are currently en route. Every contracted shipment has been delivered as expected, and importers have told the government they anticipate deliveries continuing through March and into April.

The shortages reported at regional and independent service stations are almost entirely demand-driven. Motorists have doubled their usual fuel purchases in response to media coverage of the Hormuz closure and rising petrol prices. Hardware stores have sold out of jerry cans. Some consumers are filling multiple vehicles and storing fuel at home.

Regional service stations have been hit hardest because fuel suppliers prioritize deliveries to their regular customers — typically larger chains and high-volume urban stations — during periods of tight supply. Independent operators who buy fuel on the spot market have found themselves unable to secure product at any price, leading to temporary closures in parts of regional New South Wales, Victoria and Western Australia.

Energy Minister Bowen described the rush to buy jerry cans as "un-Australian" and urged consumers to stop panic buying. Prime Minister Albanese echoed the message, telling Australians to "be a good neighbour" and take only what they need. Whether appeals to community spirit will change behavior when petrol prices are climbing 10-15 cents per litre per day is an open question.

What happens next

Fuel security through mid-April looks reasonably secure, assuming tankers continue arriving on schedule and panic buying moderates. Beyond that, Australia's position depends on three variables: the duration of the Hormuz closure, the capacity of Asian refineries to secure alternative crude supplies, and the willingness of those refineries to continue exporting to Australia when their own governments may pressure them to prioritize domestic markets.

Saudi Arabia is reportedly working to bypass the Hormuz Strait entirely by ramping up its East-West pipeline, which carries crude from eastern oil fields to the Red Sea port of Yanbu. The pipeline has a maximum capacity of about 5 million barrels per day, though it currently operates well below that level. If Saudi Aramco can bring the pipeline to full capacity, it could partially offset the loss of Hormuz exports, but the timeline for doing so remains unclear.

US and allied naval forces are conducting strikes on Iranian anti-ship positions along the Hormuz coast in an effort to reopen the strait, but Iran has shown no indication it intends to back down while airstrikes on its territory continue. French President Emmanuel Macron has proposed escorted convoys through the strait, but global insurers have indicated that premiums for vessels transiting Hormuz under current conditions would be prohibitively expensive, likely limiting commercial traffic even if a notional reopening occurs.

Treasurer Jim Chalmers told reporters on Tuesday that the "key determinant" of Australia's economic impact will be the length of the conflict. He noted that even if hostilities ended tomorrow, the global economy would not immediately return to normal. Supply chains take time to rebuild. Traders take time to regain confidence. Crude inventories at Asian refineries take weeks to replenish.

The National Cabinet meeting tomorrow will not solve any of these problems. A fuel supply coordinator cannot force tankers to arrive faster or compel Singapore to prioritize Australian contracts over domestic needs. What the meeting can do is establish clearer lines of communication between federal and state governments, between government and industry, and between industry and the public.

Former Resources Minister Ian Macfarlane, now a non-executive director at Woodside Energy, described the current situation as a structural problem decades in the making. Australia closed most of its domestic refining capacity over the past 20 years in favor of cheaper imports from Asia. That decision made economic sense when global supply chains functioned smoothly. It looks less prudent when the Strait of Hormuz closes and Singapore refineries struggle to source crude.

The government has avoided discussing fuel rationing publicly, though Transport Minister Catherine King convened a fuel security roundtable with transport industry stakeholders on Tuesday morning to discuss contingency planning. Grattan Institute energy director Tony Wood suggested that governments could request large industrial users to temporarily reduce fuel consumption if shortages intensify, similar to measures used during electricity and gas supply crunches.

Whether Australia reaches that point depends less on what happens in Canberra tomorrow and more on what happens in Tehran, Singapore and the tanker routes between them.
