Rial Hits Record Low As Bessent Readies “Economic D-Day” Assault To Isolate Iran

In the coming hours, the Trump administration is expected to unveil a sweeping campaign to economically isolate Iran and its trading partners, with China likely the primary target. The escalation is designed to force Tehran back to the negotiating table, as its only leverage – the Strait of Hormuz – appears to be quickly eroding. Commercial ships are now transiting the newly opened, US military-supervised shipping corridor off Oman, raising the possibility that Iran has partially lost control of the critical waterway.

Treasury Secretary Scott Bessent told CNBC that he would hold a press conference on Monday to “talk about exactly what we’re going to do” regarding an economic war against Tehran.

“Economic pressure means that we are going to all of our allies, and this is going to be the greatest coordinated economic isolation in the history of the world, and we are going to them and saying, ‘You are either with us or against us,’” Bessent said.

Late Sunday, Bessent wrote on X: “We are now entering the endgame. At dawn begins an economic D-Day, the single greatest financial offensive ever marshaled against an adversary.”

“President Trump has dismantled Iran’s military capabilities, destroyed nearly 100 percent of its military factories, and buried its nuclear program,” Bessent continued.

He noted, “The Islamic Republic has subsisted by dressing extortion as security guarantees. It has drawn strength from a calculus that regards Iranian retaliation as certain and American enforcement as negotiable. Under President Trump, that era is over. And those who fear the danger of defying Tehran ought not to discount the cost of testing Washington.”

In markets, Iran’s currency tumbled to a record low. The rial dropped to about 2.02 million per US dollar on the open market (bonbast.com), compared with the central bank’s official rate of roughly 1.5 million.

Even before the US and Israel operation to neuter Iran’s offensive capabilities on Feb. 28, the rial had been under pressure, coupled with persistent double-digit inflation and economic turmoil. Economic conditions have worsened since the US Navy’s blockade of the Strait of Hormuz disrupted trade and government revenue. 

The economic shock is increasingly visible across household prices. Rice has jumped 60% in just a few months, while beef prices have soared by 150%. The International Monetary Fund forecasts a 5% contraction in Iran’s economy. 

On Friday, Iranian President Masoud Pezeshkian warned of mounting economic pressure on Tehran, while cautioning against “humiliatingly” backing down “before the enemy.”

“The war must come to an end at some point,” Pezeshkian emphasized in a speech quoted by state media. “It is better that we demonstrate our strength and dignity today and tell the world that we have won and that we are ending the war.”

Tehran’s leverage over the critical waterway eroded last week as new data over the weekend showed that commercial transits through the US military-supervised Oman shipping corridor surged 400%. Trump has declared the Strait of Hormuz “an American territory.”
