Trump Declares ‘Economic D-Day’ Against Iran As Tehran Mocks It As Another ‘Failed Policy’
US President Donald Trump has declared a new phase of economic warfare against Iran, threatening countries, banks and businesses that continue providing Tehran with financial or commercial support as the nearly six month old war remains without a clear endgame and the Strait of Hormuz stays severely disrupted.
In a Truth Social post, Trump called the campaign the “MOST CRUSHING ECONOMIC OPERATION EVER TAKEN AGAINST ANY COUNTRY”, describing it as “Economic Warfare and Isolation on an unprecedented scale”. He warned that any country allowing its financial institutions, businesses, airports or government entities to provide Iran with “any type of lifeline” would face “TREMENDOUS Economic Consequences.” Trump also pointed to oil smuggling, currency swaps, cash transfers, front companies and other networks helping Tehran bypass sanctions.
But Tehran has mocked the announcement, portraying it as another failed attempt to force Iran into submission. Foreign Minister Abbas Araghchi dismissed Trump's so-called “Economic D-Day” as a diversion from America's own economic problems, specifically pointing to unprecedented US debt and surging interest costs.
“The so-called Economic D-Day is a diversion from America's own crisis: unprecedented debt & surging interest costs,” Araghchi said on social media. He warned that “doubling down on failed policies” would bring Washington “further defeat” and deepen hostility among Iranians. He also accused Washington of “economic terrorism”, saying US actions threaten the global economy and sovereignty worldwide.
Iran's response reflects Tehran's long experience with sanctions. The country has faced extensive US economic restrictions for decades and has developed alternative trading channels, informal currency markets, intermediary companies and sanctions evasion networks. That makes the central question whether Trump's latest campaign can actually create a level of economic isolation that previous sanctions failed to achieve.
The biggest challenge could be China, Iran's dominant oil customer. A truly comprehensive economic squeeze would require Washington to pressure Chinese banks, refiners and traders, potentially creating a major confrontation with Beijing just as Trump prepares for a September meeting with President Xi Jinping. Gulf financial centres, particularly Dubai, are another important part of Iran's trade network.
The strategy also depends on cooperation from US partners. Oman has been involved in diplomatic efforts surrounding Hormuz, while China has pushed for a political solution. The UAE, meanwhile, has suspended economic dealings with Iran following alleged missile threats.
Meanwhile, a secret US backed shipping corridor is reportedly keeping substantial volumes of oil moving through Hormuz. According to Axios, US officials say Washington has established a controlled route through the southern channel along Oman's coast. Around 15 to 20 tankers reportedly move through the corridor each night, carrying about 10 million barrels of oil a day, roughly half the pre-war flow.
Loaded tankers leave the Gulf while empty vessels enter to collect more crude. Movements are reportedly scheduled during nighttime windows under US military guidance, with American aircraft protecting ships against Iranian drones and cruise missiles. The operation has allegedly been running for about two months.
US officials say a two week Central Command campaign degraded Iranian radar and maritime surveillance, reducing Tehran's ability to monitor traffic through the southern channel. A task force based at Fort Bragg reportedly coordinates tanker movements with Gulf partners. Yet the corridor has not restored normal shipping. Before the war, roughly 20 million barrels of oil a day passed through Hormuz, while recent shipping data shows traffic remains far below normal.
