US Treasury Secretary Scott Bessent warned Thursday that any nation maintaining ties with Iran will face severe economic consequences. He described the administration's strategy as the toughest sanctions in history aimed at coordinated economic isolation.

Bessent stated that remaining ties to Tehran would "hasten a nation's economic oblivion," whether purposefully constructed or willfully ignored. This warning echoed President Donald Trump's earlier characterization of the effort as the "most crushing economic operation ever taken against any country."

Policy Details

• The strategy combines a naval blockade with maximum economic pressure.
• Enforcement actions target nations continuing trade with Tehran.
• The goal is to reduce Iran's proxy capabilities through financial constraints.
• Bessent framed this as an alternative to kinetic conflict, aiming to avoid a restart while curtailing Tehran's actions.

Pressure Campaign and China

Speaking on CNBC, Bessent called the campaign the "greatest coordinated economic isolation in the history of the world." He told allies they must choose between the US and continuing business with Tehran or face enforcement from the US Treasury.

When asked if the pressure campaign extends to China, Iran's largest economic partner, Bessent declined to detail specifics. He noted that China relies on the Gulf for roughly half its energy needs and suggested cooperation would "do them a big service."

Geopolitical Context

The warnings follow the expiration of a 60-day US-Iran ceasefire without a broader peace deal. A senior Iranian official has threatened a "fully offensive" posture. Meanwhile, Joe Kent, Trump's former counterterrorism chief, warned the pressure campaign could backfire by prompting Iran to strike US troops in the region.

Trump stated that Iran has some missiles and drones but limited production capacity, and that the United States essentially controls the Strait of Hormuz.

Key assertions on Iran and the Strait of Hormuz

Trump made two distinct claims regarding the regional military and strategic situation. First, he acknowledged that Iran retains some missiles and drones, while characterising the country's production capacity as limited. Second, he asserted that the US essentially controls the Strait of Hormuz and indicated that full control would follow.

The Strait of Hormuz is a critical global maritime chokepoint through which a significant share of the world's seaborne oil trade passes, making any statements about its control of broad geopolitical and energy market relevance.
