Do Oil Sanctions Really Work?

On October 22, 2025, in his boldest move yet to force Vladimir Putin back to the negotiating table, President Trump unleashed sweeping U.S. blocking sanctions on Russia’s energy giants; state-controlled Rosneft and privately held Lukoil, the two companies that pump nearly half of Moscow’s crude exports and bankroll the Kremlin’s war in Ukraine.

These aren’t slap-on-the-wrist measures. The designations freeze every asset these firms have in the U.S., ban American companies and citizens from any dealings with them, and put the world’s banks, refiners, and traders on notice: keep helping Rosneft or Lukoil, and you could be next under secondary sanctions.

Putin fired back quickly, branding the move an “unfriendly act” and vowing Russia “won’t bend,” but even he admitted “some losses are expected” as the Kremlin scrambles to shield its oil cash cow.

But looking at the big picture: do oil sanctions really work?
