On Friday, President Donald Trump signed H.R. 5334, officially titled the “Lindsey O. Graham Sanctioning Russia and Iran Act of 2026,” into law. The act serves two primary functions regarding U.S. foreign policy: it extends the expiration date of current sanctions against Iran from 2026 to 2031, and it broadens the scope of existing economic penalties, tariffs, and prohibitions currently applied to Russia.

The White House confirmed the signing in an official statement, noting that the legislation provides the executive branch with expanded statutory authority to manage these international restrictions. While the previous sanctions framework for Iran was set to expire in 2026, this new law ensures those measures remain in place for an additional five years. Furthermore, the act increases the pressure on Russia by authorizing additional tariffs and restrictions, though the specific nature of these new Russian sanctions was not detailed in the initial announcement.

The legislation is named after Senator Lindsey Graham, reflecting his involvement in the development of the policy. The signing marks a significant shift in the timeline for U.S.-Iran relations, effectively locking in a sanctions-based approach for the next several years. The move is expected to have immediate implications for international trade and diplomatic relations with both Tehran and Moscow.
