U.S. expands sanctions campaign against Iran

The United States has announced a new sanctions campaign against Iran, warning countries and companies to cut ties with Tehran within a set timeframe or face penalties from Washington. Treasury Secretary Scott Bessent said the administration is backing President Donald Trump’s calls with direct pressure from the Treasury and State Department, and that leaders and entities are being told exactly what is expected of them.

The move comes as tensions remain high over Iran’s nuclear and regional posture, with Washington increasing economic pressure while keeping military assets in place. U.S. officials say further action remains possible if talks fail, while Iran has rejected the demands as coercive and a threat to its sovereignty. Tehran has warned that any new attack would be met with a strong response and says negotiations can only continue with mutual respect and guarantees against renewed military action.

A key point of friction remains the Strait of Hormuz, where any disruption could affect global energy supplies and raise oil and gas prices. Regional states, including Oman, are still trying to preserve communication between the two sides, even as Persian Gulf countries strengthen security amid fears of wider escalation.

The sanctions package also broadens pressure on sectors tied to Iranian trade, including digital assets, technology, gold, aviation and shipping, with dozens of entities, individuals and vessels targeted for helping facilitate business with Iran.

Iran says the measures amount to economic terrorism and collective punishment, arguing that previous sanctions have harmed civilians, including access to medicine. The coming days are seen as a test of whether the standoff moves toward talks or deeper confrontation.
