With a ceasefire in the recent US-Iran conflict set to expire next week, the Trump administration is pivoting its strategy toward economic warfare rather than military action. Treasury Secretary Scott Bessent warned that the US plans to ramp up secondary sanctions on countries and companies doing business with Iran, calling it the 'financial equivalent' of a bombing campaign. The administration believes it can pressure Iran to the negotiating table by cutting off its oil revenue and access to the global financial system.

Why it matters

This shift in US strategy represents an escalation of economic pressure on Iran, going beyond the sanctions already in place. The administration hopes to force Iran to accept US proposals to limit its nuclear program, but experts warn that more sanctions could backfire and alienate allies needed to build an effective coalition against Tehran.

The details

The Treasury Department has sent letters to financial institutions in China, Hong Kong, the UAE, and Oman, threatening secondary sanctions if they continue doing business with Iran. Treasury Secretary Bessent said the US is willing to apply these 'very stern measures' to cut off Iran's access to the global financial system and oil revenue, which he described as the 'financial equivalent' of a bombing campaign. The administration believes Iran's economy is vulnerable, having suffered significant damage during the recent conflict.

  • The ceasefire between the US and Iran is set to expire next week.
  • President Trump is scheduled to visit Beijing next month for talks with Chinese President Xi Jinping.

What they’re saying

“We have told companies, we have told countries that if you are buying Iranian oil, that if Iranian money is sitting in your banks, we are now willing to apply secondary sanctions, which is a very stern measure. And the Iranians should know that this is going to be the financial equivalent of what we saw in the kinetic activities.”

— Scott Bessent, Treasury Secretary

“Instead of circumstances where we can keep sanctions on Iran and constrict their economy, the blockade in the Strait of Hormuz — combined with the sharply rising price of oil — has helped Iran's economy.”

— Elizabeth Warren, Senator

“If Iran chooses the path of economic strangulation by blockade, then the world will pass Iran by. New energy routes will be established. New supply chains will be established. Other nations throughout the region — throughout the world, and especially America — will power the world and Iran will become a footnote.”

— Stephen Miller, Deputy Chief of Staff

What’s next

The administration is preparing for a potential showdown with Iran as the ceasefire expires next week. If a new deal is not reached, the US is poised to escalate its economic pressure campaign by targeting Iran's oil exports and access to the global financial system through secondary sanctions.

The takeaway

The shift in US strategy from military to economic warfare against Iran represents an attempt by the Trump administration to force Tehran to the negotiating table and accept limits on its nuclear program. However, experts warn that this approach could backfire by alienating allies and failing to achieve the desired results, especially given the financial windfall Iran has seen from the recent conflict.
