Treasury Secretary Scott Bessent announced Friday that the United States has seized a cumulative total of roughly $1 billion in Iranian cryptocurrency assets, marking a milestone in the government's campaign to choke off the Islamic Republic's sanctions-evasion networks. The figure builds on a previous freeze of $344 million in USDT on the Tron blockchain in April and reflects the expanding reach of Operation Economic Fury, launched in March 2025.
How the tally grew
Bessent had reported nearly $500 million in late April before this update. The jump to $1 billion in about a month suggests the pace of seizures accelerated. Iran previously moved $400–500 million per month through crypto channels before the intensified pressure campaign began. The U.S. works closely with Tether and blockchain analytics firms to identify and immobilize wallets tied to oil sales and the Islamic Revolutionary Guard Corps.
Iran's stablecoin lifeline
Iran has leaned heavily on stablecoins, especially USDT on Tron, to move funds for oil sales and IRGC operations. The choice of Tron reflects its lower fees and faster settlement compared to Ethereum, as well as its popularity among Asian and Middle Eastern traders. By targeting those wallets, the U.S. has cut off a key financial pipeline that kept Iran's economy afloat despite sanctions.
What happens to the seized funds
Seized assets are held 'on behalf of the Iranian people' and could be subject to claims from victims of terrorism. That legal wrangling will play out over months. More OFAC wallet designations and potential forfeiture actions are expected in the coming months, Bessent indicated. The Treasury didn't specify which wallets were frozen this time, but said the operations are ongoing.
The broader squeeze
Iran's economy was already under strain from rial devaluation, a shaky banking sector, and reduced oil revenue. Cutting off the crypto channel removes one of its few remaining financial lifelines. The timing isn't great for Tehran — it's losing access to dollar-pegged stablecoins just as domestic inflation accelerates. Whether Iran finds workarounds or shifts to other blockchains will be the next question for enforcement agencies.
