American companies and citizens are now prohibited from conducting any financial transactions with these designated platforms.This enforcement action represents a key component of “Economic Fury,” a comprehensive initiative unveiled on April 14 targeting Iran’s access to conventional and cryptocurrency financial infrastructure.According to Treasury Secretary Scott Bessent, authorities have confiscated close to $1 billion in cryptocurrency from Iranian platforms and digital wallets since hostilities commenced in February. This disclosure came mere days before Tuesday’s sanctions announcement.“As Iran’s economy deteriorates, the regime has exploited digital asset infrastructure to advance its illegitimate objectives,” Bessent stated in an official announcement.Nobitex Serves as Hub for Iran’s Digital Currency OperationsAccording to blockchain intelligence provider Chainalysis, Nobitex functions as the central node in Iran’s “digital dollar pipeline.” The platform processes roughly half of the nation’s cryptocurrency transaction volume.Treasury officials connected Nobitex to financial transactions involving the Islamic Revolutionary Guard Corps and additional sanctioned organizations. The department also alleged the platform enabled ransomware payment processing and facilitated asset transfers from Iran following U.S. military operations.Furthermore, Treasury officials accused Nobitex of assisting Iranian government surveillance activities by handling state-affiliated transactions.Nobitex’s chief executive, Seyed Ali Khoee, and board chairman Amir Hossein Rad received individual designations on the OFAC sanctions roster. These personal sanctions subject them to direct legal restrictions under American jurisdiction.Comprehensive Offensive Against Iranian Financial InfrastructureTreasury officials indicate they have disrupted “tens of billions of dollars” in funding channels that would otherwise flow to the Iranian government and affiliated organizations.This encompasses measures against informal banking systems and international entities facilitating Iran’s petroleum exports and defense programs.American authorities have additionally issued advisories regarding sanctions exposure related to compensating Iran for “tolls” associated with transit through the Strait of Hormuz. These warnings apply to payments executed through any mechanism, including cryptocurrency and non-monetary exchanges.The Strait of Hormuz represents a vital maritime corridor transporting approximately one-fifth of global oil supply.Bessent emphasized that dismantling Iran’s nuclear capabilities remains a paramount Treasury objective. “Treasury will persistently trace financial flows in support of Economic Fury, whether through traditional banking channels or digital assets, to prevent the regime from acquiring nuclear weapons capability,” he declared.Joint U.S.-Israeli military strikes against Iran in February initiated the current confrontation and the subsequent financial enforcement operations.The post U.S. Treasury Blacklists Four Major Iranian Cryptocurrency Platforms appeared first on Blockonomi.
