Sanctions eased and bases opened: 13 March 2026

What did the Iran war mean for Europe's security map by 13 March 2026? Two decisions taken in the preceding days gave part of the answer, one touching sanctions on Russia and the other touching Romania's territory.

Washington loosens a sanctions lever

On 12 March 2026, the United States treasury department issued a temporary licence permitting the delivery and sale of Russian oil and petroleum products already loaded onto vessels before that date. The easing was to last until 11 April, and it came amid rising global energy prices. The measure was tied to the economic effects of the Iran war and also touched the embargo on Russian oil that had been built up during the Russo-Ukrainian war.

That embargo dated back to the start of Russia's full-scale invasion of Ukraine in 2022. The European Union, the G7 nations and Australia imposed sanctions, and the oil measures began in December 2022. They barred the shipping of Russian crude and refined products to the EU and other G7 nations, with a few exceptions. The American licence was temporary and limited to cargoes already at sea.

Bucharest opens its air bases

A day earlier, 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. The support was for military operations related to the Iran war. Romania took the step after approval by its parliament and by the Supreme Council of National Defence.

Two threads, one backdrop

The two decisions were separate, and the reports from those days did not tie them together. Yet both showed the Iran war reaching into the security and sanctions picture around Ukraine: one through energy markets and the treatment of Russian oil, the other through the use of a neighbouring state's military infrastructure.
