The US Treasury has sanctioned four Iranian crypto exchanges, including the country’s largest, Nobitex, marking the latest effort in its campaign called “Economic Fury” that aims to cut Iran off from the financial system.

The Treasury said on Tuesday that it added crypto exchanges Wallex, Bitpin and Ramzinex to the Office of Foreign Assets Control’s sanction list, prohibiting US businesses and persons from providing services to those platforms.

“While Iran’s economy is in free fall, the regime has chosen to co-opt digital asset technologies for its own corrupt agenda, including evading sanctions and transferring wealth out of the country,” said Treasury Secretary Scott Bessent.

The Treasury’s efforts to cut financial networks from Iran are at the center of its “Economic Fury” campaign, which commenced on April 14, months into the Iran war that kicked off with joint US-Israeli strikes on the country in February.

The US has repeatedly struck Iran amid efforts to reach a ceasefire agreement and resolve a dispute over the Strait of Hormuz, a vital shipping lane that transits about one-fifth of the world’s oil.

One of the top priorities for Treasury is to end Iran’s nuclear programme, Bessent said. 

“As promised, Treasury will continue to follow the money in support of Economic Fury, whether it is through the banking system or through digital assets, to prevent the regime from developing a nuclear weapon.”

The latest sanctions come four days after Bessent revealed that the Treasury had seized nearly $1 billion in crypto from Iranian crypto exchanges and wallets since the Iran war began.

Nobitex the centerpiece of Iran’s “digital dollar pipeline”

The Treasury said Nobitex, Iran’s largest crypto exchange, has continued to facilitate payments for the Islamic Revolutionary Guard Corps and other sanctioned entities.

On Tuesday, blockchain forensics platform Chainalysis said that Nobitex is at the center of Iran’s “digital dollar pipeline,” and that it handles about 50% of the country’s crypto trading volume.

The Treasury claimed that Nobitex has contributed to the repression of the Iranian people by facilitating state-linked surveillance of civilians. 

Nobitex’s CEO, Seyed Ali Khoee, and chairman Amir Hossein Rad were also added to OFAC’s sanction list.

The Treasury said it has cut off “tens of billions of dollars” worth of funding channels from otherwise being accessible to the Iranian regime and its proxies.

That includes action taken against alleged shadow bank networks, as well as foreign officials and companies seeking to support Iran’s oil trade and military activities.
