The U.S. government has taken decisive action by freezing more than $131 million in cryptocurrency connected to Iran's Central Bank. On July 15, 2026, Treasury Secretary Scott Bessent announced this significant move, stating that the funds were stored in wallets sanctioned by the Office of Foreign Assets Control.

Blockchain investigator Specter identified four Tron wallets holding a combined $131 million in Tether's USDT stablecoin. Tether executed the freeze based on U.S. request, utilizing built-in controls within the token. This action aims to disrupt Iran's illicit financial activities, specifically targeting its misuse of digital assets. Bessent emphasized the commitment to tackling these operations, reaffirming, "We will continue to aggressively follow the money."

Recurring Freezes of Iranian Crypto

This is not an isolated incident; it follows a prior freeze in April 2026, where approximately $344 million in USDT was also blocked due to connections to Iranian networks. One wallet alone contained around $213 million, which was found to be associated with the Islamic Revolutionary Guard Corps. In total, the U.S. has seized or frozen nearly $1 billion in Iranian-linked cryptocurrencies, illustrating the sustained focus on countering threats from this region.

Operation Economic Fury and Stablecoins

The recent actions are a part of a broader strategy known as Operation Economic Fury, initiated in March 2025. This operation targets not just crypto exchanges but also wallets and financial networks facilitating Iran's attempts to evade sanctions. The U.S. Treasury has previously sanctioned four Iranian crypto exchanges, including Nobitex, which was reported to handle over half of Iran's digital asset inflows in 2025.

Centralized stablecoins like USDT play a critical role here. Unlike Bitcoin, USDT allows for issuer-level controls that can block specific addresses from executing transactions. Tether’s approach has proven effective in recent freezes, showcasing how such digital currencies can be employed as tools for law enforcement in the global fight against illicit activities.
