Iran war delivers unexpected oil windfall for Russia

A tanker's sudden change of course in early March reflects a shift in Russia's energy fortunes.

From 22 to 26 February, the Hong Kong-flagged tanker Sarah turned off its transponders to load Russian oil from smaller ships off the coast of Oman. It then headed towards Singapore, where the cargo was likely to be transferred to another vessel bound for China.

But on 6 March, a day after the United States issued a 30-day sanctions waiver allowing Indian refiners to buy Russian crude, the tanker changed course. It is now scheduled to arrive at a refinery in western India today (14 March), reports The Economist.

The change reflects a wider shift since the start of the Iran war. The de facto closure of the Strait of Hormuz has trapped around 15% of global oil supply in the Gulf.

Brent crude, the global oil benchmark, fell to $59 a barrel in December amid expectations of oversupply. It is now around $100. Higher prices have made Russian oil more attractive to buyers. On 12 March, the United States extended its waiver to allow countries to purchase Russian oil that had already been loaded onto tankers.

Before the crisis, Russia's oil revenues had been declining. Many refiners in India and China, Russia's largest customers, stopped buying Russian crude around November before US sanctions on Rosneft and Lukoil took effect.

By February, Russia's export volumes had fallen by about a fifth. Together with lower prices, this meant the Kremlin's oil-and-gas revenues were 44% lower than a year earlier. In the first two months of the year, Russia's budget deficit reached 3.4 trillion roubles, about nine-tenths of its target for the whole of 2026.

Higher prices and renewed demand are now helping reduce a backlog of Russian oil shipments at sea. India has increased its purchases by about half, helping cut Russia's floating oil inventory by more than 10% to around 122 million barrels. China's imports have also risen.

Because these shipments had already been sold, the immediate financial benefit goes mainly to traders rather than the Russian government.

The absence of Gulf oil has increased demand for alternative supplies. Russian crude is similar in quality to Middle Eastern oil and easier for many Asian refineries to process. Urals crude delivered to India, which had previously been sold at a discount, is now priced above Brent.

Sergey Vakulenko, a former executive at Gazprom Neft, estimates that every $10 increase in Brent prices over a month raises Russia's energy export revenues by about $2.8 billion, of which roughly $1.6 billion goes to the state.

The crisis has also complicated efforts by Western countries to tighten sanctions on Russia. Before the conflict, the United States had considered tougher measures against Russia's "shadow fleet" of tankers and possible secondary tariffs.

The recent waivers have also widened differences with the European Union. The European Commission had proposed a ban on maritime services for Russian oil exports, but the plan faces opposition from Hungary and Slovakia.

Concerns over energy supply may also lead some European countries to reconsider plans to stop importing Russian liquefied natural gas next year.

China, which receives about one-third of its liquefied natural gas from the Gulf region, is also concerned about supply disruptions. This may increase interest in overland energy supplies from Russia, including the proposed Power of Siberia 2 pipeline, a 2,600-kilometre project that could significantly increase Russian gas exports to China.

Despite higher prices, analysts say Russia's gains may be limited. Ukrainian attacks on oil facilities, sanctions and reduced investment have weakened the industry.

Russia is estimated to have about 300,000 barrels per day of spare production capacity, far below the 10–15 million barrels per day of supply affected by disruptions in the Gulf.

Analysts also say Russia's oil output is likely to decline over time. Higher prices may provide temporary relief, but they are unlikely to reverse the longer-term pressures on Russia's energy sector.
