The administration of Donald Trump has frozen $344 million in cryptocurrency allegedly linked to Iran, marking a sharp escalation in financial pressure on Tehran.
The move comes amid stalled diplomatic efforts and a fragile ceasefire in the region.
U.S. Treasury Secretary Scott Bessent confirmed that authorities are sanctioning multiple crypto wallets tied to Iran. “We will follow the money that Tehran is desperately attempting to move outside of the country and target all financial lifelines tied to the regime,” he said.
Tether, which facilitated the transactions, said it worked with U.S. authorities to freeze the funds across two wallet addresses after receiving intelligence linked to unlawful activity.
A U.S. official said blockchain analysis revealed “material links” to the Iranian regime, including transactions routed through intermediary addresses connected to wallets associated with the Central Bank of Iran.
Responding to the development, Tether CEO Paolo Ardoino said the company does not tolerate illicit use of its stablecoin. “USD₮ is not a safe haven for illegal activity. When there is credible linkage to sanctioned entities or criminal networks, we act immediately,” he stated.
The crackdown underscores the growing reliance of sanctioned states on digital assets to bypass traditional banking restrictions. Data from Chainalysis shows Iran’s cryptocurrency holdings reached $7.8 billion in 2025, with the Islamic Revolutionary Guard Corps reportedly controlling about half.
Analysts say while the freeze is significant, Iran has historically adapted to sanctions. Daniel Tannebaum of the Atlantic Council noted that targeting third-party actors enabling such transactions may be key to increasing pressure.
