Singapore, the silent launderer of Russian oil

TokyoRussian oil does not disappear from the global market when it leaves Baltic or Far East ports. Often, it simply reappears under another name or label. In the waters surrounding Singapore – one of the planet's main energy and maritime hubs – hundreds of thousands of barrels of crude oil and fuel oil from Russia are transferred from ship to ship, mixed with fuels from other origins, and subsequently re-exported to Asian markets under a new commercial identity. The process, known as blending, supported by a system increasingly reliant on the so-called “ghost fleet” of convenience tankers, dilutes the product's traceability and allows derivatives linked to Russian oil to continue circulating legally within the global energy system despite Western sanctions.

The city-state does not officially import large volumes of Russian crude for domestic consumption, but its role as a logistics and financial center has become a key piece in the Asian energy reconfiguration following the invasion of Ukraine. Trading companies, shipping operators, and intermediaries use the waters near Singapore and Malaysia as a regional redistribution space, taking advantage of a system where oil can easily lose its “nationality” after being blended or refined. According to maritime data and industry sources cited by local media, Russian fuel flows to Singapore have reached record levels as operations for transfer and storage linked to Russian energy trade in Asia grow.

China has become the main driver of this new energy map. Since the beginning of the war in Ukraine, Beijing has massively increased its purchases of Russian crude, taking advantage of discounts offered by Moscow due to the loss of the European market. In April alone, according to Chinese customs data and energy analyst estimates, imports of Russian fossil fuels represented billions of euros for the Russian economy. A large part of the oil is refined in China and subsequently re-exported in the form of derivatives to other Asian and international markets, making the country a central piece in the Kremlin's financial survival.

The case of India is even more revealing. Before the invasion of Ukraine, New Delhi maintained a very limited energy relationship with Russia, as a large part of its oil traditionally came from the Persian Gulf. Today, Moscow has consolidated itself as its main crude oil supplier. The mechanism is simple and enormously lucrative: India buys Russian oil at reduced prices, refines it, and subsequently exports diesel and other derivatives to global markets, including Europe. This very month, officials from the Indian Ministry of Petroleum have publicly defended that they will continue acquiring Russian crude for "purely commercial sense", evidencing to what extent economic considerations have ended up weighing more than political alignment with the West.

Japan and South Korea

Despite the formal alignment with G7 sanctions, Japan has also ended up operating in an energy gray area. After having reduced Russian crude oil imports to almost zero following the invasion of Ukraine, the country has again received oil from Russia in recent weeks through very specific exemptions. Japanese refiners Taiyo Oil and Idemitsu Kosan have received cargoes linked to the Sakhalin-2 project, a key development in the Russian Far East in which Japanese companies such as Mitsui and Mitsubishi hold stakes. This exception, endorsed by Washington and Brussels for energy security reasons, illustrates the extent to which Western red lines can be flexible when domestic supply is at stake.

South Korea completes this map of indirect circulation of Russian crude oil in Asia. Officially aligned with international sanctions, Seoul has drastically reduced direct imports of Russian energy. However, according to data from the maritime and energy sector, South Korean refiners have increased their purchase of derivative products made from Russian crude oil that has been previously re-exported through third countries. In many cases, these operations are channeled through blends carried out in Southeast Asian waters, especially around Singapore, where the blending process allows these fuels to be reintroduced into the global market without direct traceability.

The result is an increasingly porous global energy system, where sanctions do not disappear but are reconfigured. Russian oil continues to circulate, but it does so through an architecture of indirect routes, blends, and re-exports that dilute its origin to the point of making it practically unrecognizable. On this map, Singapore is not an exception, but a structural piece of a market that continues to operate under rules increasingly misaligned with the policies that conceived them.
