US Announces ‘Economic D-Day’ Against Iran

Bessent said the Trump administration was entering what he described as an “economic D-Day” against Iran, with the United States preparing additional sanctions aimed at countries and entities that continue doing business with Tehran. He is scheduled to outline further measures Monday, with the administration signaling that the campaign could extend beyond Iran itself to trading partners, financial institutions and other organizations that help maintain the country's access to international markets. President Donald Trump has framed the effort as an attempt to isolate Iran economically after months of military conflict and pressure over its nuclear program and control of the Strait of Hormuz.

Iran has rejected the threatened measures and warned that continued economic pressure could trigger a broader response. Iranian officials have said countries that assist the U.S. campaign could be treated as participating in an act of war, while Tehran has threatened to stop oil exports from the Gulf if the economic campaign continues. The dispute is unfolding as the Strait of Hormuz, through which a significant share of the world's oil and liquefied natural gas normally passes, faces severe disruption. Iran has also announced plans involving fees for vessels using the waterway. The latest U.S. measures come after decades of sanctions against Iran, including extensive restrictions imposed since the 1979 Islamic Revolution and the Trump administration's earlier maximum-pressure campaign.
