Treasury Secretary Scott Bessent announced an expansion of secondary sanctions to isolate Iran financially, targeting nearly 60 entities and vessels.
The United States unveiled an expansion of secondary sanctions intended to isolate Iran, marking what Treasury Secretary Scott Bessent termed an "economic D-Day" against Tehran (USA Today). Announced on Monday, 24 August 2026 at the Treasury Department in Washington, the measure aims to give countries a final warning to sever business ties with the Islamic Republic or face being cut off from the dollar-based financial system (USA Today, AP News).
According to AP News reporting, the administration's campaign has been dubbed "Operation Economic Outcast." President Donald Trump's administration is struggling to find an off-ramp nearly six months into a conflict that began when the U.S. And Israel launched air strikes on Iran on 28 February 2026 (USA Today, AP News). That war has snarled regional shipping, crimped oil flows, and pushed energy prices higher (USA Today).
Bessent defended the decision to withhold immediate secondary sanctions on specific trading partners, asking reporters why he would want to blow up the global financial system and explaining that countries are being given an opportunity to shift away from Iran before penalties take effect (AP News).
The Treasury Department announced sanctions on nearly 60 entities, individuals, and vessels linked to Iran's nuclear and missile programs, cyber activities, and oil shipments, including Hong Kong-based Sweet Ocean Industrial Limited and China-based Shenzhen Huamei (USA Today, AP News). Five economic sectors were placed on notice: digital assets, technology, gold, aviation, and shipping (USA Today)."We are launching an economic onslaught against Iran’s financial connections around the globe. Our objective is to sever every economic lifeline that sustains this tyrannical regime until Tehran stands alone"

The announcement coincided with severe domestic strain inside Iran. As trading opened on currency markets on Monday, the Iranian rial dropped to a record low of 2.02 million to the U.S. Dollar, compared with the official Central Bank rate of around 1.5 million rials (AP News). Decades of prior sanctions combined with the ongoing war have fueled double-digit inflation and negative growth, making daily staples increasingly unaffordable (USA Today, AP News).
International reactions to the U.S. Strategy varied widely. Iran's parliamentary Speaker and top negotiator Mohammad Bagher Qalibaf posted on X that the U.S. Is not in an economic position to further restrict Tehran's relations, stating that trading partners have made it clear they do not take Washington's statements into account (AP News). Meanwhile, the Chinese Foreign Ministry stated that sanctions and pressure tactics do not help and that Beijing would do what is necessary to protect its interests (USA Today). Bessent maintained that no one is above the reach of U.S. Sanctions when asked about Chinese banks, though experts note Washington is treading carefully ahead of expected talks between President Donald Trump and Chinese President Xi Jinping next month (USA Today, AP News).
Diplomatic mediation efforts are moving in parallel with the economic pressure. Pakistan's army chief, Field Marshal Gen. Asim Munir, traveled to Tehran on Monday accompanied by Pakistani Interior Minister Mohsin Naqvi and other officials to meet with Iranian leaders, including Qalibaf and Interior Minister Eskandar Momeni (USA Today, AP News). Pakistani sources indicated that Trump called Munir the previous week to request assistance in bringing Iran back to the negotiating table (USA Today, AP News). Concurrently, regional conflict persists; a projectile struck a tanker west of the Saudi port city of Yanbu in the Red Sea on Monday, causing a deck fire, in an attack claimed by Iran's Houthi allies (USA Today).
What to Watch Next
- Oman's foreign minister is scheduled to visit Iran on Tuesday to discuss a potential final agreement on joint management of the Strait of Hormuz (AP News).
- Pakistani Army Chief Asim Munir is expected to continue meetings with senior Iranian officials, including the Iranian president, before returning to Pakistan (USA Today, AP News).
- Upcoming high-level talks between U.S. President Donald Trump and Chinese President Xi Jinping next month, which may test the enforcement of secondary sanctions on Beijing (USA Today, AP News).
