Bessent warns 'economic D-Day' coming for Iran in Financial Times op-ed

US Treasury Secretary Scott Bessent published an op-ed in the Financial Times on Sunday, August 23, 2026, titled 'An Economic D-Day Is Coming for Iran,' writing that 'at dawn begins an economic D-Day — the single greatest financial offensive ever marshalled against an adversary.' The op-ed previewed a Monday news conference at which Bessent detailed a sanctions push, later named 'Operation Economic Outcast,' targeting countries and entities that buy or transport Iranian oil, move money through exchange houses and free-trade zones, or maintain ship registries used by Tehran.

Why this matters. The op-ed signaled an imminent expansion of secondary sanctions to five new sectors (oil, digital assets, technology, gold, aviation and shipping), raising compliance risk for third-country buyers and shippers of Iranian crude ahead of Bessent's Monday announcement.
