Treasury Secretary Scott Bessent told reporters that Iran's economy could buckle under the weight of an accelerating US pressure campaign within a two-to-four-month window, as the administration moves to restrict Tehran's oil revenues and sever its access to global financial networks.

Speaking in a broadcast interview that aired Sunday, Bessent described a shift away from an earlier approach toward what he characterised as a strategy of full isolation, built around military operations, maritime interdictions, and sweeping financial restrictions. In a direct quote, he stated that the preceding year had been defined by a maximum pressure campaign. A full lockdown, he told reporters, had been put into effect.

Bessent told reporters that Iran had been largely cut off from global oil markets and was contending with a deepening fiscal strain, adding that no Iranian oil shipments were currently moving by sea. The organisation was operating at a cash deficit, he noted.

Measures announced by the Treasury Secretary extended to Iranian digital currency reserves, maritime trade activities, and the country's pathways into global financial systems. Bessent put forward the position that Iran had lost its grip on the Strait of Hormuz, while acknowledging that drone attacks on commercial vessels in the waterway were continuing.

Bessent noted that drone operations were conducted under cover of darkness, though the forces carrying them out did not possess the radar technology that would have been required to meaningfully disrupt shipping lanes. Large volumes of oil and petroleum products were flowing through the strategically positioned waterway, according to his account.

The Treasury Secretary went on to lay out the conditions under which Iran could reintegrate into the international community, stating that the country would need to abandon its nuclear programme and withdraw backing from armed proxy groups.

Bessent told reporters that operations carried out by the US military had gutted much of Iran's naval and air power, while knocking out a substantial share of the facilities used to manufacture missiles and drones. According to his account, the economic steps were described as operating alongside military pressure, with both instruments aimed at curtailing Iran's access to dollar-denominated transactions and weakening the stability of its financial system.

Bessent noted that Iran's currency had lost a substantial portion of its value against the dollar, dropping from around 600,000 per dollar some 18 months prior to a rate of 2.8 million at its lowest point. He added that authorities in Iran had placed restrictions on the publication of currency exchange rates as the country's financial difficulties intensified.

The approach put forward by the Treasury Secretary involved a phased plan: roughly six weeks of armed operations would come first, with a naval blockade and broad economic restrictions to follow. Bessent identified the label "Iron Wall" as the name Trump attached to the blockade.

Bessent stated that the measures had interrupted the supply of fuel, with residents in Iran reportedly waiting in petrol queues of between three and four hours. When pressed on whether the goal was a negotiated settlement or a change of government, Bessent said the path forward remained unclear, telling reporters he had no certainty about how the situation would resolve. "There's no telling how this plays out," he remarked.

Bessent outlined three possible routes: widespread popular unrest, divisions within the ranks of Iran's Revolutionary Guard, or a negotiated arrangement under which Tehran would pull back from its nuclear programme. He anticipated the standoff lasting several months, adding that mounting economic strain on Iran would likely push its leadership toward a change of course. He also conveyed that any further military action was not expected before the US midterm elections had passed.
