[Financial News] President Donald Trump of the United States, who ended a 60-day ceasefire with Iran this month, has declared that Washington will economically blockade Iran instead of resuming military strikes. Trump also warned that third countries doing business with Iran would be subject to sanctions.
On the 19th (local time), Trump posted on Truth Social, saying, "No one has given Iran more chances to make a deal than I have. Tragically, they missed that opportunity." He added, "As a result, I am announcing today the most lethal economic operation ever taken against any country!" and said, "This will be an economic war and isolation campaign on an unprecedented scale."
Trump stressed that "Iran's navy is gone, its air force has been destroyed, and its munitions factories are in ruins. Their currency is worthless, and the country itself is in crisis." He also claimed, "Today I declare that any country allowing its financial institutions, companies, airports, or government agencies to provide any form of lifeline to Iran will pay a heavy economic price." He went on to say that Iran-related "oil smuggling, currency swaps, cash transfers, ship registrations, and the creation of shell companies must stop immediately."
Trump referred to D-Day, the Normandy landings on June 6, 1944, and said the move would be "an economic D-Day." He wrote, "I urge all allies to join the United States in isolating and repelling Iran." He added, "These madmen are cornered, and these historic measures will neutralize their ability to spread terror around the world. Iran will never have nuclear weapons."

The United States, which began a war against Iran in alliance with Israel on February 28, signed a memorandum of understanding on June 17 and agreed to a ceasefire for an additional 60-day negotiation period. The agreement had already effectively collapsed in late July amid a management dispute over the Strait of Hormuz, and the written ceasefire ended on the 16th.
In a Fox News interview on the 17th, Trump said he had no intention of extending the memorandum and insisted that "Iran must raise the white flag of surrender." Regarding the war with Iran, he said, "There is no need to rush. The (U.S.) midterm elections in November have nothing to do with my thinking." He also claimed on the 18th that "there are no ongoing consultations or talks with Iran, and none are scheduled."
Foreign media have reported since last month that the United States is facing shortages of air-defense missiles and long-range strike missiles, while the aircraft carrier deployed to the region is suffering significant operational fatigue, making it difficult to expand military operations.
In response, Trump said on the 17th, referring to Iran, "They play poker well, but they are dying." He dismissed concerns raised by foreign media about a shortage of U.S. weapons, saying, "The weapons we have used so far are very limited."
Meanwhile, U.S. finance minister Scott Bessent said in an interview on the 13th, referring to Iran, "Watch for additional announcements next week," and added, "We will apply measures never before seen in the history of economically isolating a country." After mentioning the February airstrike operation against Iran, Operation Epic Fury, he said, "We have shifted from Epic Fury to economic pressure," and added, "At the president's direction, we have raised the level once again."
