The United States has opened a sweeping new front in its confrontation with Iran, launching a financial pressure campaign that Treasury Secretary Scott Bessent said is designed to shut down every remaining source of revenue for the Iranian regime. Speaking as the measures were rolled out, Bessent named the effort Operation Economic Outcast, framing it as a decisive shift from containment to elimination of the threat. President Trump has branded the package an economic D-Day, underscoring how the administration wants the announcement to be understood.
Bessent set out what he called a stark choice for Tehran, with only two paths before it: complete global isolation and a subsistence economy, or a route back toward normalcy and a chance to rejoin the global economy. He said the Treasury had mapped every node, every facilitator and every network that Iran has used to smuggle oil and evade sanctions, and that beginning immediately the government would tighten the noose on the money that funds the Revolutionary Guard. He described a zero-leakage approach that would leave no breathing space for the regime to rebuild its capacity to inflict terror.
At the core of the announcement are new sectoral sanctions determinations targeting what Bessent called five of Iran's most vital lifelines: digital assets, technology, gold, aviation and shipping. He said the determinations broaden the secondary sanctions risk for anyone who continues to do business with the regime. At the same time, he said, the Treasury's Office of Foreign Assets Control was sanctioning more than 60 entities, individuals and vessels around the world that help Iran procure illicit nuclear and missile technology, conduct cyber operations and generate oil revenue.
Much of Bessent's message was aimed squarely at third countries and companies that keep Iran's economy running. He said Iran's enablers purchase and transport its petroleum, welcome its flights and maintain aircraft registries on its behalf, turn a blind eye to seaborne fuel transfers and overland transits, and condone the illicit use of their banks. Any entity that facilitates money laundering on behalf of Iran, he warned, will be removed from the US dollar system, adding that the clock had just started ticking. He said President Trump was personally calling world leaders with specific requests that they cease their interactions with the regime.
The Treasury chief wrapped the measures in sharp rhetoric about Iran's record. He said the regime had murdered and maimed more American citizens and service members than any other terrorist regime on Earth and had been at war against America, its Gulf neighbours and much of the world for 47 years. Trump, he said, had taken action his predecessors long deferred, so that America was no longer managing the Iranian threat but ending it, with the goal of preventing Iran from ever obtaining nuclear weapons. He argued that the strength of the US economy allowed Washington to wage a sustained financial operation alongside its military.
Pressed during questions on exactly which leaders were being called and what deadlines they faced, Bessent declined to name names or set out specific timelines, saying only that the government did not have infinite patience and preferred quiet diplomacy, level-setting with every country about what it expects. He repeated that no one is above the reach of US sanctions and that any entity turning Iranian oil into money would be targeted, casting the effort as an economic asphyxiation of the regime. When asked about Chinese banks and shipping firms, he said every country and every entity should be prepared to face US action.
Bessent signalled that this was only the opening move, telling reporters they would see a wave of sanctions as Treasury, State Department and military teams fan out to meet counterparts around the world, and that the cadence would continue in the days ahead. He said he expected a major announcement of a financial institution being sanctioned by the end of the week. Cast against a conflict with Iran that has run for roughly six months, he presented the campaign as a sustained effort to collapse every last option for Tehran, one that he said would not end until the regime stands alone.
