US Treasury Secretary Scott Bessent said on Sunday, 11 October 2026 that Iran could be forced into submission within two to four months as the Trump administration escalates an economic blockade designed to sever Tehran's oil revenues, freeze its financial access, and push its economy toward collapse. Speaking on Fox and Friends Weekend, Bessent described the current campaign as a step beyond earlier pressure measures.

From Maximum Pressure to Absolute Isolation

Bessent drew a sharp distinction between Washington's earlier posture and its current strategy. 'For a year we had a maximum pressure campaign. Now we have an absolute isolation campaign,' he said. The upgraded approach reportedly combines sustained military operations, maritime interdictions, and sweeping financial restrictions targeting Iranian oil, cryptocurrency holdings, shipping networks, and access to international banking.

Bessent claimed Iran now has 'no oil on the water' and is running a negative cash flow, effectively shut out of global energy markets. He said President Donald Trump has dubbed the strategy the Iron Wall — a six-week military phase followed by a maritime blockade and comprehensive economic isolation.

Currency Collapse and Domestic Disruption

The economic toll described by Bessent is severe, according to his account. He said Iran's currency has collapsed from approximately 600,000 rials to the dollar around 18 months ago to as low as 2.8 million rials at one stage — a depreciation of more than 366%. He further claimed that Iranian authorities had stopped publishing official exchange rates as the financial crisis deepened.

Bessent also said fuel import disruptions had forced Iranians into petrol queues lasting three to four hours. He added that US military operations had reportedly destroyed a significant portion of Iran's naval and air capabilities, as well as missile and drone production infrastructure — claims that could not be independently verified.

Strait of Hormuz and Drone Warfare

The Strait of Hormuz, through which a significant share of global oil shipments pass, has remained a flashpoint. Bessent claimed Iran no longer controlled the waterway, despite ongoing attempts to disrupt commercial shipping via drone attacks. He said Iranian forces were launching unmanned aerial vehicles at night but lacked the radar capabilities to effectively obstruct maritime traffic, and that substantial quantities of oil and petroleum products continued to flow through the strait.

Conditions for a Settlement — and Three Possible Outcomes

Bessent outlined Washington's conditions for Iran's return to the international system: 'They have to give up their nuclear ambitions,' he said, adding that Tehran must also end its support for militant proxies. However, he acknowledged deep uncertainty about how the standoff ultimately resolves.

'I don't know how this ends. You never know how this ends,' he said. He outlined three possible scenarios: a popular uprising inside Iran, internal divisions within the Islamic Revolutionary Guard Corps (IRGC), or a negotiated agreement under which Tehran abandons its nuclear programme. Bessent said Trump did not anticipate further direct military engagement until at least after the US midterm elections.

The remarks signal that Washington is preparing for a prolonged economic siege, with the administration betting that financial strain will eventually force a political reckoning in Tehran — one way or another.
