U.S. Treasury Secretary Scott Bessent said the Trump administration will impose sanctions on an unnamed large bank next week, after delaying the action from September 11 because of the 25th anniversary commemoration of the 2001 attacks. The bank and its country have not been identified. Bessent said Washington will continue its economic pressure campaign until transactions with Iran’s regime stop, describing Tehran as increasingly constrained by measures targeting oil, aviation, banks and foreign affiliates. The campaign, called Operation Economic Outcast, has included sanctions on Türkiye-based Golden Global Bank and its subsidiaries, 27 Iranian airlines, and nine foreign entities, cargo providers and sales agents. Iranian President Masoud Pezeshkian said U.S. sanctions have reduced Iranian oil trade by an estimated 25% to 35% and aggravated shortages and other economic problems. President Donald Trump has said Iran would use a nuclear weapon if it acquired one, as markets monitor the conflict and further U.S. restrictions.
