The president Donald Trump announced this Wednesday what he described as "the most crushing economic operation ever undertaken against any country," aimed at the Islamic Republic of Iran, which he characterized as a nation that "hangs by a thread."
The official announced it on his Truth Social account and referred to it as an "Economic D-Day," in reference to the Allied landing during World War II.
"This will be economic warfare and isolation on an unprecedented scale," wrote Trump, who added that the Iranian navy "has vanished," its air force "is destroyed," its military factories "are in ruins," and its currency "is worthless."
The announcement comes after the failure of a 60-day negotiation period between Washington and Tehran that concluded without an agreement last week.
On Tuesday, Trump had already confirmed that there are no ongoing or planned discussions with Iran, leaving the conflict without a visible diplomatic solution.
Trump warned that any country whose banks, businesses, airports, or government entities provide a "lifeline" to Iran will face "tremendous economic consequences."
He precisely enumerated the mechanisms that must cease immediately: "Oil smuggling, foreign exchange trading lines, cash transfers, money exchange houses, ship registries, and shell companies. Everything must stop now. They know who they are."
The measure formalizes and publicly escalates the so-called Economic Fury Operation, which the Trump administration has been executing since April 2026 alongside military pressure.
The Treasury Secretary, Scott Bessent, had anticipated on Monday that measures "like never before" would be implemented against Tehran, describing the plan as a "two-pronged attack": economic isolation combined with a naval blockade of the Strait of Hormuz.
That blockade, which Trump confirmed remains "in full force and effect," impacts a route that previously channeled approximately 20% of the world's oil before the conflict.
The U.S. Senate approved new sanctions on August 7 against the Iranian energy and arms sectors, effective until 2031.
The context is one of maximum tension. This Wednesday, the British newspaper Financial Times revealed, citing two sources from the Iranian government, that Tehran is considering attacking U.S. military bases in Bulgaria and Cyprus if Trump escalates the offensive.
The general Ali Abdollahi, Chief of Staff of the Iranian Armed Forces, also issued a direct warning to the Gulf countries: "Any assistance or facilitation provided to the aggressor U.S. army will be considered as participation with U.S. military forces."
The United Arab Emirates suspended all its commercial relations, trade exchanges, and financial transactions with Iran on Wednesday, after accusing Tehran of launching two ballistic missiles against its territory.
The spokesperson for the Iranian Ministry of Foreign Affairs, Ismail Bagaei, described those accusations as "groundless."
The conflict originated from Operation Epic Fury, the coordinated attacks that the U.S. and Israel launched against Iran on February 28, 2026.
After a ceasefire and a memorandum of understanding signed in Switzerland in June, Iran declared its commitments suspended on July 18, leading Trump to resume the air offensive at the end of that month.
Trump concluded his announcement with a strong warning: "These fanatics are on the ropes, and these historic measures will paralyze them and their ability to project terror around the world. Iran will never have a nuclear weapon."
