The U.S. Treasury Department allowed a temporary general license for Russian oil sales to expire on April 11. This waiver previously permitted the sale of Russian crude loaded onto tankers before March 12. The expiration restricts a primary revenue stream for Russia and removes its barrels from compliant markets.
Energy markets currently face high volatility from the Middle East conflict and fragile U.S.-Iran ceasefire talks. The decision signals a hardening of U.S. sanctions policy. Asian buyers who utilized the waiver must now secure alternative energy supplies.
Analysts expect the move to add upward pressure on Brent crude prices. Market observers are monitoring for potential retaliatory measures from Russia following the supply tightening.
