Persistent Middle East conflicts continue to disrupt global energy markets, prompting Singapore, the world's largest bunkering port, to fill supply gaps with Russian fuel oil. This shift highlights the profound reshaping of global energy trade patterns due to geopolitical tensions.

Data from energy analytics firm Vortexa indicates that Singapore's imports of Russian fuel oil in April have already surpassed twice the monthly average for 2025 and are on track to set a new monthly record since records began in 2016.

Concurrently, fuel oil supplies from the Middle East Gulf have sharply declined. The average daily arrivals for March to April plummeted to 336,000 barrels, down significantly from the 522,000 barrels recorded in January to February.

This shift in supply structure is impacting global markets. Rystad Energy analyst Paola Rodriguez-Masiu warned that as Singapore outbids other regions, available global fuel oil cargoes are converging there. This makes it "almost inevitable" that regions like Europe will face supply tightness in the coming weeks. Although Brent crude prices have retreated from their peak near $110 per barrel in early April, they remain elevated around $105 per barrel.

The conflict's impact, particularly the blockade of the Strait of Hormuz, is the direct cause of this energy market turbulence. The Strait is a critical global energy transit route, and its blockade has not only driven up global energy prices but also caused shortages of key products like jet fuel and marine fuel.

Vortexa data shows that fuel oil cargoes from the Gulf region averaged 336,000 barrels per day in March-April, a sharp drop from 522,000 barrels in January-February. In contrast, Russian fuel oil arrivals surged from 372,000 barrels per day to 585,000 barrels per day over the same period, effectively offsetting the Middle Eastern supply shortfall.

Vessel traffic data corroborates this trend. According to BloombergNEF, ship arrivals in Singapore increased 7% month-on-month in March and nearly 15% year-on-year, as numerous vessels rerouted via Singapore to avoid Middle Eastern shipping lanes.

Supply tightness has directly driven up bunkering costs. Data from price reporting agency Argus shows that while prices have retreated from historic highs seen in late March, the cost of very low sulphur fuel oil remains approximately $800 per tonne higher than in January. This high-grade fuel is primarily used in port areas to meet emissions reduction requirements.

Argus analyst Siew Hua Seah noted that in most Asian ports, "fuel can still be found if buyers are willing to pay the premium suppliers are asking for, but stock levels are low." She also pointed out that supply availability improved in April as demand moderated and new cargoes arrived at ports, including Singapore.

Data indicates that Singapore's fuel oil inventories have fallen by approximately 11% over the past two weeks, highlighting ongoing inventory pressure.

The large-scale influx of Russian oil is occurring within a complex framework of international sanctions. Singapore itself has not imposed sanctions on specific Russian oil products, but traders utilizing Western shipping services must comply with the price cap regulations. Notably, the US has recently granted a temporary waiver on sanctions for seaborne Russian oil shipments in an effort to curb price increases.

According to maritime data company Veson Nautical, around 20 Russian tankers have called at Singapore-related anchorages this year, several of which are on EU and US sanctions lists. This compares to just five such vessels in the January-April period last year. Data from the Centre for Research on Energy and Clean Air also shows Singapore's imports of Russian oil products doubled in March compared to February, with fuel oil showing the most significant increase.

Singapore's high premiums are creating a "siphoning effect," attracting the world's limited fuel oil cargoes to Asia and creating potential supply pressures for other regions. Rystad Energy's Paola Rodriguez-Masiu stated that Europe is at a pricing disadvantage, noting, "The pain hasn't been felt yet, but in the coming weeks, it is almost inevitable that supply issues will start to appear."
