US Treasury Chief Vows 'Toughest Sanctions in History' Against Iran (2026-08-21)
Washington announces unprecedented sanctions on Iran, aiming to collapse the regime through economic pressure rather than military force.
Washington is preparing to impose what it calls the most severe sanctions ever leveled against Iran, according to Treasury Secretary Scott Bessent. Speaking on Thursday, Bessent framed the economic offensive as a potential alternative to renewed large-scale military operations, suggesting that maximum financial pressure could make a major kinetic campaign unnecessary.
His remarks came a day after President Donald Trump issued a stark warning of "Economic Warfare and Isolation on an unprecedented scale" against Tehran. Trump also threatened "TREMENDOUS Economic Consequences" for any nation providing support to Iran, a message seemingly aimed at allies and rivals alike.
Bessent described the strategy as a "one-two punch," combining the existing naval blockade on Iran with the new sanctions regime. He asserted that the pressure would be effective, stating, "It is going to work in Iran and we are going to collapse this regime." He called on allies and the international community to make a clear choice in supporting the effort.
The Treasury Secretary also addressed China, a major buyer of Iranian oil, noting that Beijing's own energy interests in the Gulf region would be served by cooperating with Washington. He suggested that further details of the plan would be unveiled at a press conference on Monday.
Iran has responded defiantly. The foreign ministry condemned the U.S. measures as "economic terrorism," arguing they target ordinary citizens and constitute crimes against humanity. Foreign Minister Abbas Araqchi dismissed Trump's threats as a distraction from America's domestic financial woes, asserting that Washington's failed policies would only deepen the divide.
The conflict, now nearly six months old, has disrupted global oil markets and raised shipping costs through the Strait of Hormuz, a critical waterway for global energy supplies. Two previous ceasefire attempts, brokered in April and June, collapsed quickly. While Trump has threatened consequences for nations like Oman, which has been mediating talks on the strait's security, Omani officials have called for a permanent regional peace and rejected further escalation.
