White House signs legislation expanding U.S. statutory sanctions, tariffs and prohibitions targeting Russia while extending existing sanctions measures against Iran

President Trump signed the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026 (H.R. 5334) into law on 18 September. According to the White House, the legislation authorises and expands statutory sanctions, tariffs and prohibitions relating to Russia and extends existing sanctions against Iran. The measure is relevant to sanctions teams because it changes the underlying statutory framework rather than simply adding individual names or entities to existing designation lists, potentially broadening the basis for future U.S. sanctions action.
