Escalating conflict in the Middle East is sending powerful shockwaves through global energy and shipping markets, with Asian bunker hubs now facing extreme volatility and tightening supply conditions. Disruptions to fuel oil flows from the region — particularly through the Strait of Hormuz — have removed a significant portion of expected supply into Asia, triggering sharp price swings and widening regional premiums, most acutely felt in Singapore.
As geopolitical tensions linked to the Iran–US war reshape trade routes and sourcing strategies, bunker market participants are being forced to react quickly to a rapidly changing physical landscape.
In this Q&A, Oilmar’s Shiwei Liao examines how Middle East conflict is feeding through into Asian bunker markets, why bunker prices respond faster than crude during logistics disruptions, and how traders and shipowners are managing risk amid unprecedented volatility.
MT: How is geopolitical risk in the Middle East currently feeding through into Asian bunker markets?
The Asian bunker market has entered a period of extreme volatility and strong bullish momentum following the disruption of Middle Eastern fuel oil flows.
Under normal conditions, roughly 1.2 million tonnes of fuel oil move from the Middle East into Asia each month. However, tanker transits through the Strait of Hormuz have reportedly fallen by around 90%, which has effectively removed a large portion of expected supply into the region.
The impact is being felt most directly in Singapore, which relies heavily on imported fuel oil feedstocks to maintain bunker supply.
Asia has not run out of fuel, but it has suddenly lost a major part of its supply pipeline.
MT: Since Oilmar is based in Dubai, is the company affected by the current Iran-US war? How is Oilmar mitigating risk and possibly leveraging this event for its bunker trading business?
As a Dubai-based trading house located near one of the world’s key energy transit corridors, geopolitical developments in the region are naturally monitored very closely. While the broader market impact is being felt through tightening fuel oil flows into Asia, our immediate focus is on managing operational and trading risk in a rapidly changing environment.
In periods of heightened volatility such as the current one, our trading desk adopts a more selective execution approach, prioritising transactions where pricing visibility, logistics reliability, and counterparty exposure are clearly manageable. The objective is to ensure that exposure to price movements and operational disruptions remains controlled while continuing to support clients with reliable supply.
At the same time, market participants across Asia are already adjusting sourcing strategies as they seek replacement cargoes from alternative supply centres. These adjustments take time due to freight constraints and longer voyage distances, which is why the market is currently experiencing a temporary imbalance between supply and demand.
For bunker trading companies, such conditions create both operational challenges and commercial opportunities. Higher fuel prices increase the working capital required for each transaction and can tighten credit conditions across the supply chain. In this environment, liquidity strength, disciplined risk management, and access to diversified supply channels become key competitive advantages.
Oilmar’s trading model – which does not depend on owned physical infrastructure – provides a high degree of flexibility to source product from multiple suppliers and regions depending on availability and pricing. This ability to adjust sourcing strategies quickly allows us to remain agile while maintaining reliable supply to customers.
Overall, while geopolitical tensions inevitably introduce uncertainty, the bunker market continues to function and adapt as global supply chains rebalance and alternative cargo flows begin to emerge.
MT: Why do bunker prices react faster than crude when logistics or shipping routes become uncertain?
What we are seeing is a classic supply-shock dynamic: prices move first, logistics adjusts later.
Bunker markets operate on tight physical supply chains, where availability depends on refinery output, barge capacity, storage inventories, and vessel scheduling. When logistics routes become uncertain, suppliers and traders immediately adjust pricing to reflect potential supply risk.
In the current environment, the immediate impact is visible through price behaviour and widening regional spreads, as buyers move quickly to secure supply and attract alternative cargoes before replacement flows arrive.
MT: When geopolitical risk rises, what tends to matter more for Asian hubs such as Singapore — actual disruption to supply flows or market “headline risk”? What indicators do you watch first in shipping and bunker markets?
In the current situation, the market reaction is being driven primarily by actual disruption to supply flows rather than headline risk alone.
The key signal has been the sharp decline in tanker transits through the Strait of Hormuz and the resulting loss of expected Middle Eastern fuel oil shipments into Asia.
The first indicators we monitor are physical logistics metrics – tanker movements, refinery exports, barge availability, and prompt cargo supply – because these determine whether the market is facing a genuine supply deficit.
The earliest visible impacts tend to appear in price volatility, prompt premiums, and widening regional spreads.
MT: If supply from the Middle East becomes less reliable, where do Asian market participants typically turn to replace barrels, and how quickly can alternatives such as US Gulf Coast or Mediterranean supply reach the region?
Market participants are actively seeking replacement cargoes from outside the region.
Potential supply is expected from the US Gulf Coast, Mediterranean markets, and occasionally long-haul cargoes redirected from Western supply centres.
However, the ability of these flows to quickly alleviate the shortage is limited. Cargoes from Western markets require several weeks of voyage time, and elevated freight costs further complicate arbitrage economics.
Even though alternative supply sources exist, the timing gap creates a temporary supply deficit in the region.
MT: We’ve seen sharp price swings and widening regional premiums at times of disruption. What do those moves tell you about physical tightness and buyer urgency in the bunker market?
The impact is most visible in price behaviour and widening regional spreads.
Over the past week, bunker prices in Singapore have increased by approximately $174 per tonne, while traders report daily price swings of $100 to $150 per tonne, which is exceptionally volatile for the bunker market.
At the same time, regional premiums have widened significantly, with Singapore VLSFO trading around $80 per tonne above Rotterdam.
These movements reflect how aggressively Asian buyers are trying to secure supply and attract replacement cargoes.
MT: How are shipowners adjusting their procurement strategies in a more volatile environment when prices are changing rapidly?
Shipowners are extremely sensitive to fuel volatility because bunker costs often represent 40–60% of voyage operating expenses. When geopolitical risk enters the market, operators tend to become more disciplined in procurement.
Some owners are securing bunkers earlier to hedge against further price spikes, while others prefer smaller, more frequent purchases to maintain flexibility. Many operators are also adopting layered procurement strategies, spreading purchases across multiple dates and locations. Flexibility between ports has become increasingly important, with shipowners wanting the option to bunker in Singapore, China, South Korea or other Asian hubs depending on availability and pricing.
In a market moving $100 per day, timing your bunker purchase becomes as important as price.
Flexibility in bunker planning has become one of the most valuable risk-management tools in shipping right now.
MT: Looking beyond the immediate market reaction, could this period of supply disruption accelerate longer-term changes in bunker supply chains or interest in alternative marine fuels?
Yes, geopolitical disruptions often accelerate diversification in energy supply chains.
When the market experiences instability linked to a particular producing region, companies begin reassessing supply chain resilience. Over time this encourages diversification of sourcing, expansion of regional refining capacity, and continued investment in alternative marine fuels.
However, structural changes take time.
The energy transition will reshape bunkering over decades – geopolitics can accelerate the pace, but it cannot replace the process.
