Trump Announces Major Economic Sanctions Against Iran to Intensify Pressure

On August 24, 2026, ahead of a planned speech by U.S. President Donald Trump, the U.S. Treasury Department announced a significant expansion of economic sanctions targeting Iran. The measures include restrictions on nearly 60 entities, individuals, and vessels linked to Iran’s nuclear, missile, cyber, and oil sectors. General licenses that previously allowed some financial transactions with Iran have been suspended. The Treasury identified five sectors for potential secondary sanctions: digital assets, technology, gold, aviation, and shipping. These sanctions also target a network of Iranian front companies and vessels operating in the UAE, Hong Kong, China, Singapore, Switzerland, and Europe.

Treasury Secretary Scott Bessant stated the U.S. will enforce a "zero leakage" policy on sanctions and is pressuring global leaders to reduce economic ties with Iran. Countries will be given specific deadlines to cease identified activities, with unilateral U.S. action threatened if compliance is not met. Among the demands is the closure of Iranian bank branches abroad within set timeframes.

In a statement between August 28 and 29, Trump described the sanctions as the "toughest economic operation ever imposed on any country," aiming to isolate Iran economically after it allegedly missed an opportunity for a deal with the U.S. He warned that nations aiding Iran financially or logistically could face severe economic consequences. The administration seeks to halt oil smuggling, cash transfers, ship registrations, and front company operations.

These U.S. moves follow earlier announcements by Secretary Bessant about unprecedented economic pressure on Iran. The campaign is also supported regionally; the United Arab Emirates preemptively suspended all trade, barter, and financial dealings with Iran, affecting an estimated $28 billion in commerce. The Iranian rial plummeted to a record low of over 2 million rials per U.S. dollar amid the escalating sanctions.

The key question remains how effectively these sanctions will be enforced, especially against major countries maintaining trade relations with Iran. The U.S. administration is actively engaging global leaders to ensure compliance and deepen Iran’s economic isolation.
