U.S. Freezes $344M in Crypto, Sanctions Iran Oil Network

The U.S. Treasury Department announced sanctions under Operation Economic Fury targeting a network of companies, individuals and vessels accused of shipping Iranian crude to China and handling related payments. As part of the action, Treasury officials froze $344 million in digital assets linked to Iranian wallets.

The sanctions were announced in phases. On April 15, the Treasury designated three Iranian currency exchange houses that were described as handling billions in revenue. On April 24, the U.S. Navy seized a tanker linked to the same network. A second round of designations on May 11 added nine companies and three individuals for roles in arranging oil shipments to China.

Officials described China as the destination for much of the shadow fleet’s cargo. Iran relies on oil exports for an estimated 80% of state revenue, and authorities have identified a network of tankers, front companies and alternative payment channels used to move crude and convert proceeds.

Iran has used cryptocurrencies to move value outside traditional banking since at least 2018, including documented use of Bitcoin and other tokens in oil-related transactions. Earlier in April, Iranian officials reportedly proposed accepting Bitcoin for tanker transits through the Strait of Hormuz.

The $344 million freeze is larger than prior annual estimates of roughly $150 million linked to Iranian crypto flows. Market analysts noted that frozen wallets can create selling pressure if counterparties or automated systems liquidate holdings. Some crypto analysts forecast potential 2% to 5% declines in Bitcoin prices from the sanctions and the resulting market overhang.

The Treasury also warned it may pursue secondary sanctions against foreign banks and refineries that support the smuggling network. That warning includes the possibility that exchanges or financial institutions processing transactions tied to the designated wallets could face enforcement actions.

The enforcement activity combines financial penalties and maritime interdiction to target both shipments and the payment systems that enable them. Treasury officials indicated that compliance expectations for firms handling digital assets may increase if regulators expand the scope of sanctions-related risks to include crypto service providers.
