Trump Declares 'Most Crushing Economic Operation Ever' Against Iran

President Donald Trump announced Wednesday that the United States is launching the most crushing economic operation ever taken against any country, escalating pressure on Tehran as negotiations to end a more than five-month conflict remain deadlocked. In a Truth Social post, Trump declared the campaign would be economic warfare and isolation on an unprecedented scale and demanded that U.S. allies join Washington in isolating the Iranian regime.

Trump framed the announcement as a decisive response to Iran's refusal to reach a deal, warning that the regime's window for a diplomatic settlement has closed.

An Economic D-Day Against Tehran

Trump called the new campaign an economic D-Day and warned that any nation providing a lifeline to Iran will face tremendous economic consequences of its own.

Any country that allows its financial institutions, businesses, airports, or government entities to support Iran will be hit hard, Trump said. He specifically called out the channels that keep Tehran's economy afloat: oil smuggling, swap lines, cash transfers, exchange houses, ship registries, and front companies.

It all needs to stop now, Trump wrote, adding a pointed warning to nations still doing business with the regime.

Iran Hanging by a Thread

Trump described an Iranian regime under severe strain after months of U.S. military and economic pressure. He said Iran's navy is gone, its air force destroyed, its military factories reduced to rubble, and its currency worthless, with the country hanging by a thread.

These maniacs are on the ropes, and these historic measures will cripple them and their ability to project terror worldwide, Trump said. He reiterated his core demand in all capital letters: Iran will never have a nuclear weapon.

The announcement comes as the Strait of Hormuz, one of the world's most critical oil shipping lanes, has been effectively closed since early March amid the U.S.-Iran standoff.

Maximum Pressure, Amplified

The new campaign builds on the Trump administration's Operation Economic Fury, launched in April to cut off Iran's terror financing and revenue streams by penalizing foreign banks and companies that do business with Tehran.

Treasury Secretary Scott Bessent previewed the escalation last week, telling Newsmax that Washington would impose economic isolation on Iran like the world has never seen before. He said the administration would combine unprecedented economic pressure with the continued naval blockade in the Arabian Sea, keeping vessels from entering or leaving Iranian ports.

Reports indicate the administration is prepared to target Chinese teapot refineries that buy discounted Iranian oil and Chinese financial institutions involved in processing Iranian funds, a move that would dramatically expand the enforcement reach of existing sanctions.

What Happens Next

Trump did not spell out every measure in the new operation, but the message to the world is clear: doing business with Iran now means doing business with an economic wall the United States is building around the regime.

Allies have been called on to stand with Washington in isolating Tehran, and the coming weeks will show which nations heed the warning. With the Strait of Hormuz still closed and pressure mounting on multiple fronts, Iran faces its most difficult moment yet -- and the president has made clear there will be no letup until the regime stands down and surrenders any nuclear ambitions for good.
