A rising number of vessels are diverting to Singapore as the Iran conflict disrupts key Middle Eastern shipping lanes, but local bunker fuel sales have fallen as ship operators become increasingly conservative about refueling due to oil price volatility, according to industry experts.
Live News
- Vessel diversion: The Iran war has forced many ships to avoid the Strait of Hormuz and adjacent waters, pushing them toward Southeast Asian routes. Singapore, as a major deepwater port, is seeing a spike in transit vessel calls.
- Fuel sales dip: Despite higher ship arrivals, bunker fuel offtake has not kept pace. The volatility in crude oil prices—linked directly to conflict developments—has made ship operators hesitant to buy large fuel volumes.
- Price volatility impact: Spot prices for marine fuel 0.5% sulfur (VLSFO) have fluctuated sharply in recent weeks, with swings of over US$30 per metric ton within single trading sessions, according to market participants.
- Operational pressure: The influx of vessels is straining port resources. Anchorages are fuller than normal, and some ship agents report delays of up to 48 hours for bunker delivery services.
- Geopolitical risk premium: Insurers have increased war risk premiums for vessels transiting the Middle East, further incentivizing rerouting and conservative fuel buying.

Key Highlights
The ongoing Iran war is causing significant disruption to traditional shipping routes through the Middle East, leading to a notable increase in vessel arrivals at the port of Singapore this month. Ship operators are rerouting to avoid conflict zones, seeking safer transit lanes and alternative ports of call.
However, despite the higher traffic, data from port authorities and fuel suppliers indicates that the volume of bunker fuel purchased in Singapore has declined relative to the number of arriving ships. Industry experts attribute this trend to heightened caution among shipowners and charterers. The geopolitical turmoil has introduced extreme oil price swings, making it difficult for vessel operators to lock in fuel costs. As a result, many are adopting a "just-in-time" fueling strategy—purchasing only the minimum amount needed to reach the next port rather than filling tanks at a single stop.
“Ships are more conservative in buying fuel amid price volatility due to the conflict,” noted one regional shipping analyst. The shift is impacting Singapore’s position as the world’s top bunkering hub, though the port remains a critical safe haven for vessels seeking shelter from the conflict. The increase in ship arrivals has also brought logistical challenges, including congestion at anchorage areas and longer waiting times for berthing.

Expert Insights
From a market perspective, the divergence between vessel arrivals and bunker demand in Singapore highlights a fundamental shift in shipping behavior during geopolitical crises. Vessels are prioritizing safety and cash preservation over traditional fueling efficiency. This suggests that while Singapore benefits from increased traffic, its fuel sales volume may not fully recover until oil price volatility subsides.
The cautious fuel-buying pattern could persist for the duration of the Iran conflict, potentially affecting margins for local bunker suppliers and storage operators. If the conflict drags on, some analysts believe that port congestion in Singapore may worsen, leading to higher demurrage costs for charterers and ultimately pushing freight rates upward.
Investors watching the maritime fuel sector should note that the current environment does not necessarily signal a structural weakening of Singapore's bunkering hub status. Instead, it reflects a near-term operational adjustment. A more stable geopolitical backdrop would likely restore normal fueling patterns. In the meantime, ship operators are likely to continue managing fuel purchases on a shorter-term basis, keeping a close eye on the daily crude futures market.
