US Treasury Secretary Announces Economic Isolation Strategy on Iran

Treasury Secretary Scott Bessent announced the US will sever all economic ties with Iran and isolate any nation partnering with Tehran financially, marking a stated shift from military to economic pressure after months of armed conflict. In a Financial Times opinion piece, Bessent wrote that the objective is to "sever every economic lifeline that sustains the tyrannical regime until Tehran stands alone." Bessent is set to hold a news conference Monday to unveil the specific measures. Bessent urged Iran's allies to cut ties with Tehran, saying that doing so would "deepen their access to global capital, reinforce confidence in their markets and attain the standing they seek in the world economy," per CBS News. The isolation strategy tests whether the US can force third countries to choose between economic access to global capital markets and partnership with Iran. The announcement follows a pattern of US ultimatums in this conflict. According to the BBC, Trump said in April that "a whole civilisation will die tonight" unless Iran agreed to end the war and unblock the Strait of Hormuz. The US eventually backed down after mediator Pakistan called for more diplomacy. Trump withdrew from the Obama-era nuclear deal in 2018 and reimposed sanctions on Iran. In April of this year, the Trump administration launched additional sanctions on foreign banks and firms doing business with Tehran after military operations failed to force Iran's regime to surrender, the BBC reports. Iran rejected Bessent's announcement. The Financial Times reports that Iran said it would shut down all oil exports from the region if the war continues. According to CBS News, Iran's foreign ministry spokesman Esmaeil Baghaei said previous similar US attempts to pressure Iran had failed and that "the Iranian people will show that they are determined and steadfast in safeguarding their rights." Baghaei characterized the new measures as evidence the Trump administration had "miscalculated" its attacks and believed "military aggression could bring the Iranians to their knees." Economic distress is already visible on the ground. According to CBS News, Iran's currency hit a record low on Monday as traders anticipated the new sanctions: the rial dropped to 2.02 million to the US dollar on informal currency markets, where most Iranians conduct business. The official Central Bank rate stands at around 1.5 million rials to the dollar. Meanwhile, parallel negotiations continue. Oman and Iran are set to hold talks Tuesday on the future management of the Strait of Hormuz, with Oman's foreign minister travelling to Tehran. Some details have emerged about possible transit fees for ships and specific entry routes, according to CBS News. Iranian President Masoud Pezeshkian defended the June memorandum of understanding with the US, saying there is "not a single provision in this agreement that amounts to capitulation," per CBS News. Pezeshkian told his security council the agreement represented "the best possible" outcome based on dignity and national interest. The Strait of Hormuz carries roughly one fifth of the world's oil and gas. Iran has effectively blocked the flow since the conflict began in late February and has issued a new warning that ships must not pass without its permission, according to the BBC.
