U.S. Sanctions on Russian Oil Giants Escalate Tensions Over Ukraine

The United States has imposed sweeping sanctions on Russia’s two largest oil companies, Rosneft and Lukoil, in a move aimed at tightening economic pressure on Moscow over its ongoing war in Ukraine. The measures, announced by the Treasury Department, block U.S. assets and restrict business dealings with the firms and dozens of their subsidiaries.

Treasury Secretary Scott Bessent said the sanctions were necessary due to President Vladimir Putin’s “refusal to end this senseless war,” stressing that the Kremlin’s energy revenues continue to fuel its military campaign.

The decision marks a sharp policy shift by President Donald Trump, who only recently signaled openness to direct talks with Putin. The sanctions announcement coincided with the cancellation of a planned summit between the two leaders, underscoring Washington’s frustration with stalled peace efforts.

The move rattled global energy markets, with oil prices climbing by as much as 3% amid fears of supply disruptions. India, one of Russia’s key energy buyers, is reportedly weighing a reduction in imports to avoid secondary sanctions exposure.

Moscow reacted angrily, accusing Washington of undermining global energy stability and vowing countermeasures. Russian officials warned that the sanctions would not alter their military objectives in Ukraine but would instead deepen the rift between the two powers.
