US sanctions Iranian crypto exchanges including Nobitex as Treasury tightens digital asset crackdown

The US Treasury’s Office of Foreign Assets Control has dramatically expanded its sanctions campaign against Iran’s digital asset sector, designating the country’s largest crypto exchange and several affiliated platforms for allegedly supporting terrorist financing and helping Tehran sidestep international restrictions.

On June 2, 2026, OFAC placed Nobitex, Wallex, Bitpin, and Ramzinex on its sanctions list, citing their connections to the Islamic Revolutionary Guard Corps and involvement in illicit financial flows. Nobitex, which processed more than 50% of Iran’s digital asset inflows in 2025, sits at the center of this crackdown.

How Iran built a crypto lifeline

OFAC didn’t stop at the platforms themselves. Nobitex executives, including Amir Hossein Rad, were individually designated alongside the exchange, a signal that Treasury is holding people accountable, not just corporate entities.

The June designations were followed by additional actions in August 2026, when OFAC sanctioned Shelbit Exchange and Aban Tether for maintaining connections to the previously blacklisted Iranian platforms.

In July 2026, OFAC moved against several crypto wallets linked to Iran. That action had an immediate downstream effect: Tether froze over $131 million in Tron addresses associated with those wallets.

Operation Economic Outcast and the broader campaign

These designations fit into a larger strategic framework. Treasury’s Operation Economic Outcast and its Economic Fury campaign are designed to systematically dismantle Iran’s financial infrastructure, with the digital asset sector now firmly in the crosshairs.

The mechanics of the sanctions matter here. US persons are barred outright from transacting with any designated entity. Foreign institutions face secondary sanctions risk, meaning a bank or exchange anywhere in the world that facilitates transactions with these platforms could find itself cut off from the US financial system.

One name that has circulated in connection with this story is Bitbank, the Japan-based digital asset exchange. The research is clear on this point: Bitbank has not been included on any US sanctions lists and has publicly maintained compliance with OFAC regulations. The Japan-based platform has distanced itself from any dealings connected to designated Iranian entities. Any conflation of Bitbank with the Iranian exchanges targeted by OFAC is factually incorrect.

What this means for the broader crypto market

For the global crypto market, the most immediate implication is liquidity. When Tether freezes $131 million in Tron addresses, that capital doesn’t simply move elsewhere cleanly, creating disruption in the networks where those funds were active.

Investors holding assets on or connected to any of the designated platforms face a more immediate problem: frozen funds and no clear path to recovery within a US-aligned financial system. Wallex, Bitpin, and Ramzinex users are in the same position as Nobitex users, caught in a regulatory net that now spans multiple platforms and their executive teams.
