The U.S. is preparing to implement significant economic sanctions against Iran, marking what officials describe as an unprecedented financial offensive.

"At dawn begins an economic D-Day – the single greatest financial offensive ever marshalled against an adversary," wrote Bessent in the Financial Times.

In response, Iran has threatened to halt all oil exports from the Gulf, stating, "If the economic war continues, not a single drop of oil will be exported, neither through the Strait of Hormuz nor from anywhere in the Persian Gulf," according to Rezaei.

Iranian officials have warned that any support for U.S. sanctions would be viewed as "an act of war."2

Iranian Foreign Minister Abbas Araqchi dismissed the sanctions as a sign of U.S. desperation, asserting, "We have never been afraid. All of their actions... have failed, and this new issue of theirs will fail as well."3

The U.S. Central Command has intensified its naval presence, redirecting commercial vessels and enforcing a blockade.

Meanwhile, Iran's Persian Gulf Strait Authority announced that vessels violating Iranian protocols would face restrictions, as fewer than 20 commodity vessels transited the strait over the weekend, indicating rising tensions in the region.56
