Treasury Secretary Scott Bessent announced a new round of sanctions aimed at Iran on Monday and warned every country that does business with the Islamic Republic to sever those financial ties or face retaliation from the United States. President Donald Trump's pledge last week to unleash an “economic D-Day” against Tehran turned out to be new warnings to cut off Iran from the rest of the global economy. Asked why the U.S. was not imposing secondary sanctions on Iran's trading partners, Bessent told reporters he wanted countries to have an opportunity to shift away from Iran before it was too late. “Why would I want to blow up the global financial system?” Bessent said. The Trump administration is struggling to find an off-ramp nearly six months into an unpopular war with an increasingly obstinate Iran. Washington had promised new sanctions would put even more pressure on an Iranian economy already battered by previous penalties and a U.S. naval blockade.
