The US Treasury has ordered the freezing of more than $131 million in cryptocurrency linked to Iran, confirming what onchain data had already revealed hours earlier. Blockchain investigator Specter identified four Tron wallets holding $131 million in USDT that Tether had frozen on Tuesday. Treasury Secretary Scott Bessent confirmed the Iran crypto freeze on X, stating the wallets were tied directly to the Central Bank of Iran. “US Treasury is committed to disrupting and degrading Iran’s illicit financial activities, including its abuse of digital assets,” Bessent said.
The freeze came as the ceasefire between the US and Iran collapsed. The US announced a renewed blockade of Iranian ports alongside a fresh wave of military strikes by Central Command. Iran’s military claimed it responded with drone strikes on US facilities at Jordan’s Al Azraq Air Base.
A Pattern With a Running Total
This is not an isolated action. In April, Tether froze $344 million in USDT at the request of US authorities — covered in this publication at the time. In May, Bessent disclosed that the US had seized approximately $1 billion in Iranian crypto assets since the launch of Operation Economic Fury in March 2025, a financial pressure campaign designed to dismantle Iran’s ability to fund its military through foreign procurement networks. The $131 million Tuesday brings the publicly confirmed total higher still.
“Treasury has frozen the Iranian regime’s assets, severely disrupted its economy, and dismantled the Iranian war machine,” Bessent said in a June statement. The operations have targeted not just wallets but entire financial networks, including Iran’s top crypto exchange, which was sanctioned separately as hostilities escalated.

Iran Crypto Freeze Confirms What the Industry Keeps Avoiding
Three major Iran-linked crypto freezes in under four months, executed within hours of onchain activity being detected, tell a story the crypto industry has been slow to reckon with publicly. Tether is operating as a real-time enforcement arm of US financial sanctions. The speed and precision of these freezes – $344 million overnight in April and $131 million within hours on Tuesday – demonstrate a level of coordination between a private stablecoin issuer and US government authorities that has no equivalent in traditional finance.
The implications are significant. USDT is the liquidity backbone of a vast portion of global crypto trading, DeFi activity, and cross-border value transfer. Every wallet holding USDT exists at the discretion of a company that will freeze it on instruction from Washington. That is not a theoretical risk but a demonstrated operational reality, now confirmed across multiple high-profile actions. For Iran, the lesson is that crypto is not a reliable sanctions escape route when the dominant stablecoin is issued by a US-adjacent company. For the broader crypto industry, the lesson is that decentralisation is only as real as the assets at its base layer, and right now, that base layer answers to the US Treasury.
