Treasury Secretary Scott Bessent said on Sunday the United States is “entering the endgame” in the monthslong conflict with Iran as an “economic D-Day” is set to begin on Monday.

In an opinion piece in the Financial Times, Bessent wrote about the strategy behind the planned slew of economic policies that he called “the single greatest financial offensive ever marshaled against an adversary.” President Donald Trump said earlier in the month that the U.S. would begin shifting away from military pressure toward economic policies meant to further harm Tehran’s economy and isolate it from global commerce.
