'Economic D-Day' sanctions against Iran will be 'single greatest financial offensive ever' Bessent says

The crushing “economic D-Day” sanctions being unleashed against Iran will be “the single greatest financial offensive ever marshaled against an adversary,” Treasury Secretary Scott Bessent said hours before they are revealed Monday. The imminent announcement of the impending financial penalties follows Bessent’s comments on CNBC Friday that the US would “collapse the regime” with the “toughest sanctions in history” as President Trump warned any nation providing “any type of lifeline” to Iran would face their own economic consequences. 3 US Treasury Secretary Scott Bessent is set to unleash economic ‘D-Day sanctions’ against Iran. Andrew Thomas / CNP / SplashNews.com “President Trump has dismantled Iran’s military capabilities, destroyed nearly 100 percent of its military factories and buried its nuclear program,” Bessent wrote Sunday night on X . “We are now entering the endgame. As dawn begins an economic D-Day – the single greatest financial offensive ever marshaled against an adversary,” he continued. Tehran has pledged “crushing, punishing and devastating” consequences should the US move ahead with its planned crippling sanctions — while warning other nations that support of the sanctions will be seen as an “act of war.” Explore More Ex-Illinois deputy who fatally shot Sonya Massey over pot of hot water dead in prison at 32 Cause of death revealed in horror case of LI teacher and mom of 4 who died after driving SUV into pool Girl, 8, dies after contracting suspected brain-eating amoeba linked to lake swim But Bessent seemingly batted down the threat in his Sunday social media post. “The Islamic Republic has subsisted by dressing extortion as security guarantees. It has drawn strength from a calculus that regards Iranian retaliation as certain and American enforcement as negotiable,” he wrote “Under President Trump, that era is over. And those who fear the danger of defying Tehran ought not to discount the cost of testing Washington.” 3 A veiled Iranian woman walks past an anti-US billboard featuring US President Donald Trump in southern Tehran, Iran, on Monday, August 24, 2026.

CENTCOM Bessent penned a column in the Financial Times Sunday in which he drew parallels between the US’ planned sanctions campaign with the original June 6, 1944 D-Day, when allied forces stormed the beaches of Normandy, France. “As Roosevelt and Churchill weighed a campaign that would culminate in the Normandy landings, they asked themselves what could be done ‘to bring the greatest pressure to bear on the enemy,'” he wrote, invoking a refrain originating from the 1943 Tehran Conference convened ahead of the campaign. “History has returned that question to Tehran. And the moment has arrived to answer it with the full weight of American resolve,” he warned. “President Trump is doing what his predecessors refused by ending a threat they resigned themselves to managing,” Bessent wrote, taking a swipe at previous administrations’ lack of decisive action against the regime. “For decades, the political class accepted an endless cycle of provocation instead of advancing American interests. Not another generation should be condemned to the menace of fanatics who devote themselves to ‘death to America’ and fulfilling the regime’s nuclear ambitions,” he wrote. “And total financial isolation can obviate the need for American force while enlarging the sphere of freedom for our allies.”
