US Warns Hormuz Digital Asset Payments May Trigger Sanctions Risk

The U.S. Treasury Department warned that using digital currencies to pay for passage through the Strait of Hormuz could lead to sanctions. They clarified that digital assets don’t lessen the legal risks for shipping companies, banks, insurance providers, or anyone else involved in these transactions.

Key Takeaways:

  • OFAC warned crypto payments tied to Hormuz transit may trigger sanctions exposure.
  • Reports say Iran operates a crypto-based toll system generating about $20 million in daily revenue.
  • Foreign firms risk secondary sanctions and restricted access to U.S. financial system.

OFAC Alert Raises Crypto Sanctions Risk for Hormuz Transit

The U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) issued a May 1 alert warning that digital asset payments tied to Strait of Hormuz passage can create sanctions exposure. The warning makes clear that crypto does not reduce legal risk for maritime firms, financial institutions, insurers, or counterparties. OFAC said Iran-linked demands for safe transit can appear in several forms. The warning states:

Attackers might ask for payment in various forms, like traditional money, cryptocurrency, credits against future attacks, bartering, or even disguised payments – for example, donations to organizations like the Iranian Red Crescent, Bonyad Mostazafan, or accounts linked to Iranian embassies.

The warning comes alongside reports that Iran is actively accepting cryptocurrency under what is being called a formal “Tehran Toll Booth” regime for Strait of Hormuz transit. The system, codified on March 31, 2026, remains in active use. Bitcoin is the primary payment method, with reported USDT usage, though Tether froze more than $344 million in Iranian-linked assets in late April. Oil tanker fees run $0.50 to $1.00 per barrel, or roughly $2 million per very large crude carrier (VLCC).

OFAC also said U.S. persons are generally barred from transactions involving the Government of Iran unless exempt or authorized. That restriction also covers dealings with Iran’s Islamic Revolutionary Guard Corps (IRGC). OFAC separately flagged crypto platforms tied to Iran. “U.S. persons are also generally prohibited from engaging with Iranian digital asset exchanges, which are considered blocked Iranian financial institutions under U.S. sanctions,” the alert states, showing that digital asset payments are treated as sanctions exposure, not as a workaround.

Maritime Firms Face Enforcement Pressure Over Digital Asset Payments

TRM Labs calculates that Iran’s Revolutionary Guard Corps (IRGC) earns around $20 million each day. Even outside the U.S., individuals and entities still risk facing sanctions if they do business with the IRGC or the Iranian government. The U.S. Office of Foreign Assets Control (OFAC) warns that foreign parties could be penalized for such transactions, potentially losing access to the U.S. financial system. OFAC further stated:

People and entities outside the U.S. who use digital asset exchanges blocked due to their connection with Iran could also face penalties, as this activity would be considered support for Iran’s financial system, which is subject to sanctions.

Even if you’re not directly involved in a transaction, you could still be held liable if it goes through U.S. insurers, banks, or other financial institutions. This is especially true for companies involved in shipping. Because of this risk, it’s important to be clear about how payments are made and to carefully check the identities of everyone involved. U.S. authorities recommend reviewing ships, finding out who arranged their passage, and checking if any payments were made to or promised for parties connected to Iran. The way Iranian shipping operates requires ships to submit ownership and cargo information through intermediaries before being approved. Payments are then routed through a specific process involving designated accounts and a verification code, often with a naval escort. This complex system means it’s crucial to verify payment details and the identities of all parties to ensure compliance with regulations.

Separate late-April developments have made the risks around these payment systems more visible. On April 21, reports said the IRGC fired on a vessel after it paid a fraudulent crypto wallet instead of an authorized address. On April 30, Treasury Secretary Scott Bessent said Operation Economic Fury had seized $500 million in Iranian crypto assets. These developments show that digital assets are central to both payment activity and enforcement action.
