Did a US sanctions waiver on Russian oil test the embargo?
A temporary US licence on 12 March 2026 eased restrictions on Russian oil cargoes already at sea, as energy prices rose amid the Iran war.
What did it mean for sanctions on Russia when Washington eased them on 12 March 2026? On 13 March 2026, the day this retrospective covers, the move was a day old, and it sat alongside a second development tied to the same conflict.
The US treasury department issued a temporary licence permitting the delivery and sale of Russian oil and petroleum products that had been loaded onto vessels before 12 March. The easing was set to run until 11 April and was issued amid rising global energy prices linked to the Iran war.
The embargo context
Since Russia's full-scale invasion of Ukraine in 2022, the European Union, the G7 nations and Australia have imposed sanctions on Russia. The oil measures began in December 2022 and included an embargo on bringing Russian crude and refined products to the EU and other G7 countries by ship, with a few exceptions. The US licence was narrow in scope: it covered only cargoes already loaded, and it carried an expiry date.
A second front of the Iran war
On 11 March 2026, Romania authorised the United States to use its air bases to refuel aircraft and to deploy monitoring and satellite communications equipment in support of military operations related to the Iran war. The decision followed approval by the Romanian parliament and the Supreme Council of National Defence.
What it meant for Kyiv
The two decisions show how the Iran war was reaching into policy on Russia and Ukraine's neighbourhood. Energy prices pushed Washington to loosen a sanctions constraint for a limited period, while a state bordering Ukraine formally opened its bases for US operations. Whether the oil waiver would be extended was a question for after 11 April; on 13 March 2026 it was simply a time-limited exception.
