KEY POINTS
- Fuel oil traders in Asia are facing a critical supply crunch as regional conflict in the Middle East has caused tanker transits through the Strait of Hormuz to plummet by 90 percent this week.
- The shortage is hitting high-sulphur fuel oil (HSFO) hardest, with typical monthly volumes of 1.2 million metric tons destined for Asia now largely stalled at the chokepoint.
- Major regional suppliers, including China and Thailand, have reportedly suspended their own fuel exports to safeguard domestic reserves, further tightening the Asian market.
The Asian energy market is reeling from a massive disruption in the global fuel oil trade following a week of intense military activity in the Persian Gulf. According to data from energy intelligence firm Kpler, the flow of fuel oil through the Strait of Hormuz—the world’s most critical maritime chokepoint—has almost entirely ceased. Inbound and outbound tanker traffic has fallen to just 10 percent of its normal levels as shipowners and insurers avoid the region due to missile strikes on tankers and the suspension of war risk cover. This sudden halt has disconnected Asian refiners and bunker hubs from their primary source of heavy residual fuels.
The impact is most acute in the bunker fuel sector, which powers the world’s commercial shipping fleet. Singapore, the global leader in ship refueling, is seeing a rapid depletion of its high-sulphur fuel oil stocks, which are primarily sourced from Middle Eastern producers. With shipments from Saudi Arabia, the UAE, and Kuwait unable to reach their destinations, traders are being forced to look toward the West, including the U.S. Gulf Coast and Europe, for replacement cargoes. However, the long transit times and high “arbitrage” costs associated with these alternative routes are expected to drive bunker prices to multi-year highs in the coming weeks.
Further complicating the crisis is a wave of “resource nationalism” among Southeast Asian nations. Facing the prospect of a prolonged conflict, governments in China, Thailand, and Indonesia have moved to restrict or entirely suspend their petroleum exports. These measures are designed to ensure that domestic power plants and transport sectors have sufficient reserves to weather a potential 60-day supply gap. For smaller, import-dependent economies like the Philippines and Vietnam, these export bans remove a vital secondary layer of supply, leaving them vulnerable to both physical shortages and predatory pricing in the spot market.
The primary bottleneck remains the limited capacity of alternative export routes. While Saudi Arabia has successfully tripled its oil exports from Red Sea ports to bypass the Gulf, these pipelines are primarily designed for crude oil rather than refined fuel products. Other regional producers, such as Iraq and Kuwait, lack significant bypass infrastructure and have already begun cutting production at refineries because their storage tanks are full and no tankers are available to load. Analysts warn that if the Strait remains restricted for another two weeks, the regional surplus will turn into a global deficit, potentially pushing oil prices toward the $100 mark.
As the situation enters a critical second phase, Asian industrial hubs are preparing for “extreme scenarios.” In India and South Korea, refiners are exploring increased imports of Russian oil as a temporary fix, while Japan has indicated it may soon need to tap into its strategic petroleum reserves. For now, the global high-sulphur complex remains in a state of paralysis, highlighting just how dependent the world’s most populous region remains on a single, increasingly volatile geographic pinch point.
