American lawmakers have introduced a bipartisan bill in the US Senate aimed at imposing stricter sanctions on Russian oil imports, intensifying economic pressure on Moscow amid the ongoing war in Ukraine.

The legislation, called the Decreasing Russian Oil Profits Act of 2025, was presented by Senators David McCormick and J. Husted (Republicans) alongside Elizabeth Warren and Chris Coons (Democrats). According to Ukraine’s Ambassador to the United States, Oksana Stefanishyna, the bill targets both the purchase and facilitation of Russian oil, with potential consequences for countries, companies, or financial intermediaries involved.

“The import of Russian oil directly supports the war against Ukraine,” Stefanishyna wrote on Facebook. “This bill creates a legal framework to increase sanctions pressure on Russian oil revenues, with clear risks for those facilitating these trades, including losing access to the US financial system.”

If approved, the legislation would require the US President to impose sanctions within 90 days on individuals or entities importing Russian oil. The Treasury Secretary, after consulting the Secretary of State, would compile a list of those subject to restrictions. Stefanishyna highlighted that this step reflects strong bipartisan support for further economic measures against Russia.

This move follows earlier US actions against major Russian oil companies. On October 22, the Treasury Department sanctioned Rosneft, Lukoil, and their subsidiaries, calling on Moscow to halt military operations in Ukraine. Experts have warned that these sanctions could restructure the global oil market, prompting forced asset sales and changes in ownership across refineries and oil fields worldwide.
