Treasury freezes Iran's four crypto exchanges

OFAC designated Nobitex and three more Iranian exchanges on 2 June, cutting off the stablecoin route the Central Bank used to defend the rial and the IRGC used to bank Hormuz tolls.

Key takeaway

Treasury froze the crypto exchanges that funded both Iran's rial defence and the IRGC's Hormuz tolls.

The US Treasury's Office of Foreign Assets Control, OFAC, designated Nobitex on 2 June under two authorities at once: Executive Order 13224, the counterterrorism order, and Executive Order 13902, which covers Iran's financial sector 1. Nobitex is Iran's largest cryptocurrency exchange, handling more than half of all Iranian digital-asset inflows in 2025. Treasury named three more exchanges beside it: Wallex at 12 per cent of inflows, Bitpin at 10 per cent, and Ramzinex, through which $2.45 billion had passed. Four of Iran's busiest exchanges lost dollar access on a single day.

Four individuals went on the list under the counterterrorism order, including Nobitex chairman Amir Hossein Rad and two members of the Kharrazi family, who sit inside Mojtaba Khamenei's inner circle. Treasury says it has now frozen close to $500 million in regime-linked crypto under its Economic Fury campaign, the same thread that began with the PGSA designation on 28 May . The State Department added a $15 million bounty through Rewards for Justice for information disrupting IRGC financial mechanisms 2.

Follow the plumbing. Nobitex was the rail the Central Bank of Iran used to reach dollar stablecoins and slow the rial's fall, and the IRGC (Iran's Islamic Revolutionary Guard Corps) levied its Hormuz tanker tolls in those same stablecoins . The same designation that drains the currency defence also drains the toll machine, because both flows passed through the named exchanges. Defenders call it the cleanest pressure available short of force. Critics note that crypto rails reroute fast, and an exchange can spin up fresh wallets in a weekend, so the freeze's bite depends on whether foreign counterparties actually refuse the named wallets.

Deep Analysis

In plain English

Iran has been cut off from the normal global banking system for years because of US sanctions. To get around this, Iranians started using cryptocurrency, especially a type called USDT (a 'stablecoin' pegged to the dollar), traded through local crypto exchanges. The four exchanges named here (Nobitex, Wallex, Bitpin and Ramzinex) together handled most of this traffic. The US Treasury on 2 June put all four on its sanctions list, which means any company worldwide that does business with them risks being cut off from the US financial system. This matters in two ways: the Iranian government was using these exchanges to buy dollars and prop up its own currency, and Iran's Revolutionary Guard (the IRGC) was using them to collect toll payments from ships passing through the Strait of Hormuz.

Deep Analysis
Root Causes

The IRGC's Hormuz toll machinery from the Persian Gulf Strait Authority (PGSA) required a payment channel that was denominated in dollar stablecoins, accepted pseudonymously, and settled outside the US correspondent banking system.

Nobitex met all three conditions simultaneously. The CBI independently needed Nobitex for the same reason: its own SDN-list status since 2019 blocked it from the dollar market, and the 43% rial devaluation through May 2026 created urgent demand for dollar-liquidity tools.

The second structural cause is that Iran's domestic banking system has no capacity to absorb the exchange rate pressure: with inflation running above 40% and the rial at a record low on 1 June, the stablecoin rail was the CBI's only lever for open-market intervention. Designating Nobitex simultaneously removed the IRGC toll revenue channel and the CBI stabilisation tool, hitting two distinct institutional functions with one instrument.

What could happen next?
  • Consequence

    Nobitex and the three co-designated exchanges will attempt address migration within days; OFAC will need to post successor-wallet updates to maintain the designation's operational effect.

    Immediate · Assessed
  • Risk

    The CBI loses its open-market dollar-intervention tool just as diplomatic momentum re-emerges, increasing the probability that a future rial slide will be sharper and faster than the 43% six-month slide already documented.

    Short term · Reported
  • Precedent

    Designating a state's central bank satellite exchange sets a template for targeting any country using crypto rails to evade sanctions, with implications for Venezuela, North Korea and Russia's evolving stablecoin infrastructure.

Update #116 · Washington signs a sanction, not a strike

Different Perspectives
Markets
Markets
Brent crude rose 2.2 per cent to $96.34 on 10 June, reversing a 7 per cent weekly decline built on deal optimism, as the overnight exchange repriced the Strait of Hormuz risk premium in a single session. The move reflects transit-risk repricing rather than supply shock: Iran's exports had already collapsed to below 300,000 barrels per day.
Pakistan
Pakistan
Pakistan's Naqvi channel, the only mediation track carrying both civilian and military buy-in, was stress-tested by live ordnance within 48 hours of the 6-7 June Tehran visit. Whether Washington informed Islamabad of the imminent strike plan while Naqvi was in Tehran remains undisclosed, putting the channel's neutrality under scrutiny.
Kuwait
Kuwait
Kuwait hosted the third Iranian strike on its soil since the 3 June airport drone attack, with Ali Al Salem airbase targeted in the three-country salvo. Its recent $1.98 billion Anduril Anvil counter-drone purchase signals it is rearming rather than reconsidering its hosting posture.
Bahrain
Bahrain
Bahrain absorbed the IRGC barrage via PAC-3 intercepts with its magazine already at 87 per cent depletion and no resupply before 2027. Sounding air-raid sirens over Manama, it faced the intercept burden with the thinnest defensive stack in the Gulf coalition.
Jordan
Jordan
Jordan reported all five incoming missiles intercepted with no injuries and no damage, a clean defensive performance that strengthens Amman's case for staying in the Western coalition without escalating its own posture. It now sits on Iran's target list for the first time despite not being a party to the Abraham Accords confrontation.
Iran / IRGC
Iran / IRGC
Foreign Minister Araghchi posted on X that US forces should 'leave our region if you want to be safe' and framed the exchange as a US defeat, while the IRGC claimed 21 targets hit and an F-35 hangar destroyed. The claims serve a domestic and Arab-audience framing rather than a verified battle-damage assessment.
