U.S. Treasury Blocks $131 Million in Crypto Associated with Iran

Summary

• The U.S. Treasury's Office of Foreign Assets Control (OFAC) has sanctioned cryptocurrency wallets linked to Iran's military and central bank, resulting in Tether freezing over $131 million.
• The sanctions affected four Tron blockchain addresses, with analysts tracing the funds back to DTC Pay and Bitso transactions.
• Additionally, the Treasury sanctioned seven individuals involved in arms procurement for Iran.

The U.S. Treasury has taken significant action against cryptocurrency assets associated with Iran, imposing sanctions on multiple wallets tied to the Central Bank of Iran and the Islamic Revolutionary Guard Corps (IRGC). This move prompted Tether to freeze over $131 million across four Tron blockchain addresses.

Scott Bessent, the Secretary of the Treasury, confirmed the sanctions via an announcement on X, emphasizing the U.S. commitment to blocking access to funds that support the Iranian regime. Alongside this, sanctions were also placed on seven individuals linked to a network facilitating weapons procurement for Iran.

The recent sanctions underscore the ongoing scrutiny of Iran's financial activities, particularly in the cryptocurrency space. Tether, a stablecoin that maintains a dollar peg, can freeze wallet addresses, effectively rendering the funds in those accounts inaccessible.

On-chain analyst Specter identified the affected addresses prior to the Treasury’s announcement, linking them to both the IRGC and Iran's central bank. The analyst noted that prior transfers to these wallets occurred through DTC Pay and Bitso, indicating a pattern of evading traditional financial oversight.

The transparency of blockchain technology facilitates these enforcement actions, allowing U.S. authorities to trace financial flows effectively. As cryptocurrency strategies become more centralized, they may face increased vulnerability to regulatory measures.

Research from blockchain analytics firms indicates that Iranian crypto activity reached nearly $10 billion in 2026. The U.S. had already seized approximately $1 billion in Iranian crypto assets during an ongoing effort known as Operation Economic Fury.

This operation follows earlier freezes, including a previous action where Tether halted $344 million in USDT associated with Iran. The increased collaboration between Tether and law enforcement has resulted in over $4.4 billion in frozen assets globally, illustrating the growing intersection of cryptocurrency and regulatory enforcement.
