The U.S. Treasury Department has sanctioned four Iranian cryptocurrency exchanges as part of its ongoing financial pressure campaign against Iran. The move targets Nobitex, Iran’s largest crypto platform, along with Wallex, Bitpin, and Ramzinex.
The sanctions were announced Tuesday by the Treasury’s Office of Foreign Assets Control, known as OFAC. U.S. businesses and individuals are now barred from providing any financial services to these platforms.

The action is part of a broader effort called “Economic Fury,” launched on April 14. The campaign is designed to cut Iran off from both traditional and digital financial systems.
Treasury Secretary Scott Bessent said the U.S. has seized nearly $1 billion in crypto from Iranian exchanges and wallets since the Iran war began in February. That announcement came just four days before Tuesday’s sanctions.
Blockchain analytics firm Chainalysis said Nobitex sits at the heart of what it calls Iran’s “digital dollar pipeline.” The exchange handles around 50% of all crypto trading volume in the country.
The Treasury linked Nobitex to payments involving the Islamic Revolutionary Guard Corps and other sanctioned entities. It also accused the exchange of facilitating ransomware payments and helping move assets out of Iran after U.S. bombing began.
The Treasury also claimed Nobitex helped the Iranian state surveil its own citizens by processing state-linked transactions.
Nobitex’s CEO, Seyed Ali Khoee, and chairman Amir Hossein Rad were added to the OFAC sanctions list personally. This means they face direct restrictions under U.S. law.
The Treasury said it has cut off “tens of billions of dollars” in funding channels that would otherwise be accessible to the Iranian regime and its proxies.
That includes action against shadow banking networks and foreign companies supporting Iran’s oil trade and military operations.
The U.S. has also warned about the sanctions risk tied to paying Iran “tolls” for passage through the Strait of Hormuz. Those warnings cover payments made in any form, including crypto and in-kind donations.
The Strait of Hormuz is a critical shipping lane that carries around one-fifth of the world’s oil supply.
The U.S. and Israel launched joint strikes on Iran in February, which triggered the current conflict and the start of the financial campaign that followed.
