The United States Treasury Department on August 24 unveiled sweeping sanctions targeting more than 60 entities in what Treasury Secretary Scott Bessent called “Operation Economic Outcast,” an unprecedented financial campaign designed to isolate Iran from global commerce as the US-Iran war nears its six-month mark.
Bessent announced the measure at the Treasury Department, describing it as an “economic D-Day” and an “economic onslaught” against Iran’s financial networks worldwide. The campaign aims to sever what Bessent called “every economic lifeline that sustains this tyrannical regime until Tehran stands alone,” according to his prepared remarks.
The sanctions target entities across the Middle East, China, Singapore, Hong Kong, the United Arab Emirates, Malaysia, the United Kingdom, France, Greece, Syria, Ukraine, and the Marshall Islands, according to Al Jazeera’s analysis of the Treasury designation list. The targeted entities include procurement networks accused of helping Iran obtain sensitive technology for nuclear research and missile development, companies facilitating oil revenue generation, and networks supporting cyberoperations.
Treasury imposed new sectoral sanctions determinations covering five critical sectors of Iran’s economy: digital assets, technology, gold, aviation, and shipping. These sectoral designations broaden the scope of secondary sanctions—penalties on third parties conducting business with Iran—that the US can impose on foreign entities and countries.
Bessent warned countries and companies to cut their ties with Iran or face secondary sanctions, though he declined to name specific nations or provide a timeline for enforcement. “Every country has a defined timeline to shut down activities we have identified,” Bessent said in his remarks. “If they do not take action, we will do so unilaterally through Treasury authorities.”
The Treasury Department specifically singled out Iran’s Bank Melli, which operates branches in Europe, the Middle East, and Asia. “Every branch of Bank Melli must be shuttered and dark,” Bessent stated. Reuters reported that Treasury has imposed Iran-related sanctions on more than 1,000 people, vessels, and aircraft since Trump’s second term began in 2025.
The timing coincides with severe currency pressure on Iran’s economy. Iran’s rial hit a record low of 2.02 million to the US dollar on August 24-25, 2026, according to ABC News and The Independent, as the new sanctions were announced. The currency has lost roughly 20,000 times its value over four decades, according to reporting by Euronews.
Iran rejected the latest sanctions. Economy Minister Ali Madanizadeh told the Fars News Agency that the new measures will fail, saying “US sanctions against us are not new. We have programmes to counter American sanctions, and Washington cannot achieve its goals by severing the arteries of our economy.” Iranian government spokeswoman Fatemeh Mohajerani stated on X that “the government and the president, with wisdom and resolve, will guide the country through this phase.”
China, Iran’s largest oil buyer for several years, was notably spared from the initial sanctions list. Reuters reported that Washington declined to target Chinese financial institutions suspected of facilitating Iran’s oil trade, likely to avoid provoking Chinese retaliation ahead of a scheduled Trump-Xi meeting in late September. Bessent said he did not want to “blow up the global financial system” but warned that no country was “out of the reach of U.S. sanctions” if it facilitates transactions turning Iranian oil into revenue.
Daniel Fried, a former US State Department sanctions coordinator now with the Atlantic Council, told Reuters that the announcement “did not live up to the hype,” but added that economic pressure is preferable to restarting military conflict. He cautioned that the pressure campaign will require patience and possibly concessions to secure cooperation from other nations.
