US President Donald Trump has announced a major new economic pressure campaign against Iran, warning that countries and businesses that provide support to Tehran could also face severe consequences.
Trump made the threat on Wednesday as the conflict with Iran approaches its sixth month, with diplomatic efforts showing little sign of producing a lasting agreement.
In a statement on Truth Social, Trump described the campaign as an unprecedented economic operation against Iran and warned that any country allowing its financial institutions, businesses, airports or government agencies to provide support to the Islamic Republic would face what he called “tremendous” economic consequences.
However, Trump did not specify the exact measures that could be imposed on countries that violate the warning, and he did not identify any country by name.
US Steps Up Economic Pressure
The announcement comes less than a week after US Treasury Secretary Scott Bessent warned that Washington would impose economic isolation on Iran on an unprecedented scale.
The latest threat signals an expansion of the US campaign beyond Iran itself, potentially putting foreign governments and companies that maintain economic ties with Tehran under pressure.
Hormuz Remains A Major Flashpoint
The threat also comes amid continuing tensions over the Strait of Hormuz, a vital global energy route.
Despite a recent reduction in missile attacks, Iran has maintained an effective blockade of shipping through the strait following the collapse of a US-Iran agreement aimed at reopening the waterway.
The dispute has become a major obstacle to diplomatic efforts, with Washington demanding the restoration of freedom of navigation while Tehran continues to use control of the strategic passage as leverage.
Trump had earlier suggested that the strait could become a “new U.S. territory” and, on Tuesday, indicated that talks with Iran were no longer taking place.
No Clear Diplomatic Exit
Although both Washington and Tehran have acknowledged that messages are still being exchanged, there is currently no clear path toward ending the conflict.
Trump’s latest warning raises the possibility of broader economic pressure involving countries that continue doing business with Iran, potentially expanding the economic consequences of the conflict beyond the two countries.
The announcement comes as Trump also faces increasing domestic political scrutiny over the war ahead of the November elections.
