19, 2026. —Al Drago––The Washington Post/Bloomberg/Getty Images Iranian officials have dismissed President Donald Trump ’s threat to launch what he called the “most crushing economic operation”against Tehran , as the nearly six-month war enters a new phase of economic pressure and negotiations between the two countries remain stalled.

Trump announced the campaign late Wednesday, threatening consequences for countries that continue to provide Iran with access to global trade and financial networks.

“This will be economic warfare and isolation on an unprecedented scale,” he said .

“Any country that allows its financial institutions, businesses, airports, or government entities to provide any type of lifeline to Iran will itself face tremendous economic consequences.” Trump did not specify what specific measures would be imposed on countries that continue to do business with Iran.

TIME has reached out to the White House for comment.

The President also called on U.S. allies to impose additional restrictions on Tehran in order to “cripple them and their ability to project terror worldwide.” “This will be an economic D-Day, and we need all of our allies to stand with the United States of America to isolate, and defeat, the Iran threat,” he said.

D-Day commonly refers to June 6, 1944, Allied landings on the beaches of Normandy, France, which opened a major Western front against Nazi Germany.

Treasury Secretary Scott Bessent said on Thursday the United States ​will impose "maximum economic pressure" on Iran.

"It ⁠is a one-two punch.

We have the blockade (on Iran), and we are going to have the toughest sanctions in history," Bessent told CNBC.

"It is going to work in Iran and we are going to collapse this regime." How Iran responded Iranian officials rejected Trump’s threats and instead pointed to the strains the conflict has placed on the U.S. economy .

Iranian Foreign Minister Abbas Araghchi called the move a “diversion from America's own crisis: unprecedented debt & surging interest costs.” “Doubling down on failed policies will only bring further defeat—and enmity of Iranians.

U.S. economic terrorism threatens global economy and sovereignty worldwide,” he said Thursday morning.
