US Treasury Blacklists UK Crypto Exchanges in First-Ever Iran Designation

The Receipt

The U.S. Treasury Department sanctioned two UK-registered cryptocurrency exchanges Friday, marking the first time the Office of Foreign Assets Control (OFAC) has targeted digital asset platforms specifically for operating within Iran’s financial sector. The designation targets Zedcex Exchange Ltd. and Zedxion Exchange Ltd., entities the Treasury claims are front companies for the Islamic Revolutionary Guard Corps (IRGC).

Market Reaction

The regulatory enforcement hit an already skittish market. Bitcoin slid 5.5% to $84,158, while Ethereum dropped 6.7% to $2,808. Institutional capital fled alongside retail; spot Bitcoin ETFs recorded $1.49 billion in net outflows over the week, with Friday alone accounting for $509 million in exits. The broader risk-off sentiment was compounded by a sharp 33% correction in silver prices.

The Mechanism: $94 Billion in Shadow Volume

This is not a case of rogue wallets; it is state-level infrastructure evasion. According to OFAC, Zedcex has processed over $94 billion in transactions since its launch in 2022. The operation was allegedly orchestrated by Babak Morteza Zanjani, an Iranian billionaire previously sentenced to death for embezzlement but released to facilitate money laundering for the regime.

The Treasury identified the specific vector: high-volume USDT transfers on the Tron network. OFAC designated seven specific Tron addresses used by Zedcex to route funds, effectively freezing those assets within the reach of U.S. jurisdiction. This confirms a long-standing compliance thesis that Tron remains the preferred rail for sanctioned jurisdictions due to its low fees and high throughput.

Institutional Implications

This action forces a re-evaluation of counterparty risk for UK and EU-based compliance desks. Zedcex and Zedxion held UK registrations, offering a veneer of legitimacy that likely bypassed basic geofencing filters. Treasury Secretary Scott Bessent was explicit about the intent:

“Rather than build a prosperous Iran, the regime has chosen to squander what remains of the nation’s oil revenues on nuclear weapons development, missiles, and terrorist proxies around the world… The United States will continue to disrupt sanctions evasion using all tools available, including virtual assets.”

The sanctions also targeted Iran’s Interior Minister, Eskandar Momeni Kalagari, linking the crypto-enabled revenue directly to the funding of violent crackdowns on domestic protests.
