The Group of Seven industrialized nations and their allies have tried since late 2022 to curb Russia’s oil income by capping the price of its seaborne crude, using their dominance in shipping and insurance to keep barrels flowing while limiting revenue for the Kremlin’s war in Ukraine. In February 2026, the European Union and United Kingdom began enforcing a reduced cap of 44.10 dollars per barrel under a dynamic mechanism that adjusts every 22 weeks to stay 15% below average market prices for Russia’s Urals crude, but the United States has so far kept its own 60‑dollar ceiling in place.
Russia has countered with a growing “shadow fleet” of older tankers using opaque ownership, flags of convenience and risky shipping practices to move most of its oil outside Western service providers, while Ukraine and its partners respond with expanding sanctions on vessels and the people who operate them. In early March 2026, however, U.S. Treasury Secretary Scott Bessent signaled that Washington may temporarily lift sanctions on additional Russian oil beyond a 30‑day waiver already granted for cargoes bound for India, arguing that releasing “hundreds of millions” of stranded barrels could ease wartime supply shocks—raising questions about how long the current sanctions-first strategy and price‑cap coalition will hold.
