US sanctions against Russia’s two largest energy companies, the state-owned Rosneft and privately held Lukoil, are perhaps the most significant economic measures imposed by the West since the invasion of Ukraine.

If fully implemented, they have the potential to significantly choke off the flow of fossil fuel revenue that funds Russia’s war machine, but their power lies not in directly denying Russia access to the tankers, ports and refineries that make the oil trade turn, but the US financial system that greases the wheels.

Ever since the invasion, the Russian government has proved masterful at evading sanctions, aided and abetted by allies of economic convenience and an oil industry with decades of experience.

New US sanctions on Russia: What do we know?

While the West, principally the EU, has largely turned off the taps and stopped buying Russian oil, China, India and Turkey became the largest consumers, with a shadow fleet of tankers ensuring exports continued to flow.

Data from the Centre for Research into Energy and Clean Air (CREA) shows that while fossil fuel revenues have fallen from more than €1bn a day before the war, they have remained above €600m since the start of 2023, only dipping towards €500m in the last month.

None of that oil has been heading for the US, but these sanctions will directly impact the ability of the Russian companies, and anyone doing business with them, to operate within America’s financial orbit.

According to the order from the US Office for Foreign Asset Control, the sanctions block all assets of the two companies, their subsidiaries and a number of named individuals, as well as preventing US citizens or financial institutions from doing business with them.

It also threatens foreign financial institutions that “facilitate transactions… involving Russia’s military-industrial base” with direct or secondary sanctions.

In practice, the measures should prevent the two companies from accessing not just dollars, but trading markets, insurance and other services with any financial connection to the US.

Taken in harness with similar steps announced by the UK earlier this month, analysts believe they can have a genuinely chilling effect on the market for Russian oil and gas.

Russia’s customers for oil in China, India and Turkey will also be affected, with the largest companies, state-owned and private, expected to be unwilling to take the risk of engaging directly with sanctioned entities.

Indian companies are already reported to be “recalibrating” their imports following the announcement, which came just a week after Donald Trump announced an additional 25% import tariff on Indian goods as punishment for the country’s reliance on Russian oil.

That does not mean that Russian oil and gas exports will cease. There are other unsanctioned Russian energy companies that can still trade, and ever since the first barrel of oil was tapped, the industry has proved adept at evading sanctions intended to interrupt its flow from one country or another.

Any significant increase in the oil price beyond the 5% seen in the aftermath of the announcement could also put pressure on the White House, which is at least as sensitive to fuel prices at home as it is to foreign wars.

But analysts Kpler expect the sanctions to cause “an immediate, short-term hiatus in Russian crude exports, as it will take time for sellers to reorganise and rebuild their trading systems to circumvent restrictions and ease buyers’ concerns”.

And Russian gas will, for now, continue to flow into Europe, where distaste for Vladimir Putin‘s imperial ambitions has not killed the appetite for his fuel. While the EU has this week imposed sanctions on liquified natural gas (LNG), they will not be fully enforced until 2027.
