President Trump signs law expanding Russia sanctions

President Trump signed a law on September 19, 2026 expanding U.S. sanctions on Russia and extending Iran sanctions, officials said, broadening tariff and statutory authorities.

Expanded tariff and statutory authorities

Officials said the statute authorizes a wider range of economic measures against Moscow, including new statutory sanctions and explicit tariff powers that the administration can deploy. The text, officials added, also carries provisions that preserve and extend current restrictions on Iran.

The law gives executive agencies discretion to move more quickly on export controls, asset freezes and tariff steps, officials said, while leaving the details of target lists and implementation to Treasury and Commerce. That sequencing — congressional authorisation followed by administrative rules — means immediate policy effects depend on how rapidly agencies issue guidance.

Officials said agencies will issue implementation guidance within 30 days, setting an initial timetable for enforcement and licensing changes. Markets and trading partners will watch those notices for sectoral scope, exemption criteria and any measures that could affect supply chains or tariffs.

Expect Congress and the administration to hold oversight hearings in the weeks after guidance appears; the first reviews are likely within a month of the agencies’ notices, officials said.
