Affected by the blockade of the Strait of Hormuz, fuel supply from the Gulf region has plummeted by 36%. To fill the energy supply gap, Singapore has urgently turned to Russian fuel, and its imports of Russian fuel in April are expected to soar to a record monthly high. Meanwhile, the price of marine fuel has surged by more than $800 per ton since the beginning of the year, and the high premium in the Singapore market is forming a "siphon effect". Energy agency Rystad Energy warns that an imminent energy supply crisis in Europe is "inevitable" within weeks.
The ongoing conflict in the Middle East has severely disrupted the global energy market order. As the world's largest ship refueling port, Singapore is gradually increasing its imports of Russian fuel to fill the supply gap left by the Middle East. This shift in energy import structure reflects the profound reshaping effect of geopolitical conflicts on the global energy trade pattern.
As of Friday, April 24, data from energy statistics firm Vortexa shows that Singapore's imports of Russian fuel in April have more than doubled the average monthly level in 2025 and are expected to hit a record monthly high since records began in 2016. Russian oil has become the core force for Singapore to fill the energy gap.
In sharp contrast to the surge in Russian oil imports, fuel supply from the Middle East Gulf region has shrunk sharply. Data shows that between March and April, the total average daily arrival of fuel from the Gulf region plummeted from 522,000 barrels in January-February to 336,000 barrels, resulting in a significant supply gap.
This shift in Singapore's energy supply structure is gradually spreading to the global energy market. Paola Rodriguez-Masiu, an analyst at Rystad Energy, warned that due to Singapore's higher bids for fuel than other regions, available fuel cargoes worldwide are continuously concentrating in Singapore, and regions such as Europe will "almost inevitably" face an energy supply crunch in the coming weeks. Currently, although Brent crude oil prices have pulled back from the high of nearly $110 per barrel in early April, they remain stable around $105 per barrel, and the trend of high energy prices persists.
War Impact: Hormuz Blockade Triggers Energy Supply Disruption
The outbreak of the Iranian conflict and the blockade of the Strait of Hormuz are the direct triggers of the current global energy market turmoil. They have not only pushed up global energy prices as a whole but also caused shortages of key energy products such as aviation fuel and marine fuel (referred to as bunker fuel), affecting the stability of global shipping and energy supply.
As one of the world's most important energy transportation routes, the disruption of navigation in the Strait of Hormuz has directly cut off the core path for energy export from the Gulf region. Vortexa data further confirms the severity of the supply gap: between March and April, the total average daily arrival of fuel from the Gulf region was only 336,000 barrels, a sharp drop from 522,000 barrels in January-February; correspondingly, the total average daily arrival of Russian fuel during the same period rose from 372,000 barrels to 585,000 barrels, basically offsetting the fuel supply gap in the Middle East and easing Singapore's energy pressure.
Ship traffic data also confirms this shift in the energy supply pattern. According to BloombergNEF data, Singapore's ship arrivals in March increased by 7% month-on-month and nearly 15% year-on-year. A large number of ships have diverted to Singapore for berthing and refueling to avoid dangerous routes in the Middle East, further increasing Singapore's fuel demand.
Price Surge: Marine Fuel Costs Rise by Over $800 Since the Start of the Year
The tight energy supply situation has directly driven a sharp surge in marine fuel prices. According to data from price reporting agency Argus, although bunker fuel prices have pulled back from the all-time high at the end of March, the price of the highest-grade low-sulfur marine fuel is still about $800 per ton higher than at the beginning of January this year. This grade of fuel is mainly used for ships in port areas to meet global ship emission reduction requirements, and its price increase has directly raised the operating costs of shipping companies.
Siew Hua Seah, an analyst at Argus, said that currently, in most Asian ports, "fuel can still be found as long as one is willing to pay the premium required by suppliers, but overall inventory levels are low." She also pointed out that with the slight decline in market demand and the arrival of new fuel cargoes at major Asian ports including Singapore, fuel availability in April has improved compared with the end of March.
Inventory data shows that Singapore's fuel inventory has dropped by about 11% in the past two weeks, and inventory pressure cannot be ignored, which means that the tight energy supply situation in Singapore has not been fundamentally alleviated.
Influx of Russian Oil: Compliant Operations Under Sanction Frameworks
Singapore's large-scale imports of Russian fuel are compliant operations carried out under a complex international sanctions framework, which do not violate relevant international rules or its own regulations.
It is reported that Singapore itself has not imposed sanctions on specific Russian oil products, but traders using Western shipping services must strictly abide by the price cap provisions in relevant international sanctions. Notably, the United States has recently temporarily exempted sanctions on seaborne Russian oil, aiming to curb the continuous rise in global energy prices and ease global energy supply pressure.
According to statistics from maritime data company Veson Nautical, about 20 Russian oil tankers have docked at relevant anchorages in Singapore since the beginning of this year, among which several are on the EU and US sanctions lists; in contrast, only 5 Russian oil tankers docked in Singapore between January and April last year, representing a significant increase. In addition, data from the Center for Research on Energy and Clean Air shows that Singapore's imports of Russian oil products in March doubled compared with February, with the largest increase in fuel imports.
Currently, the high premium in Singapore's fuel market is generating an obvious "siphon effect", continuously attracting limited global fuel cargoes to the Asian region, which also puts other regions such as Europe under potential energy supply pressure. Paola Rodriguez-Masiu, an analyst at Rystad Energy, pointed out that Europe is at a disadvantage in terms of fuel pricing: "Currently, no obvious supply pressure is felt, but supply shortages will almost inevitably start to appear in the coming weeks."
