Iran’s Hormuz Crypto Toll Comes With a Guarantee of Safe Passage – and a Sanctions Violation
Blockchain intelligence firm Chainalysis has published an analysis responding to reports that Iran's Islamic Revolutionary Guard Corps has begun collecting cryptocurrency transit fees from commercial vessels in the Strait of Hormuz.
Key Takeaways
- Iran has formalized a crypto-denominated transit fee for the Strait of Hormuz, charging up to $2 million per vessel, according to both firms.
- Blockchain analytics make crypto sanctions evasion easier to trace than traditional banking, contradicting Iran’s pitch of untraceable payments.
- Shipping companies that pay the toll face material support designations under U.S. law, regardless of which currency or blockchain is used.
Ship operators are already negotiating fees through an IRGC-linked intermediary, submitting vessel ownership details, cargo, destination, and crew information before receiving a permit code for safe passage. Hamid Hosseini, spokesperson for Iran’s Oil, Gas and Petrochemical Products Exporters’ Union, stated publicly that tankers would be “given a few seconds to pay in bitcoin, ensuring they can’t be traced or confiscated due to sanctions” – a claim that blockchain analysts have since picked apart in detail.
According to Chainalysis, IRGC-linked addresses accounted for more than 50% of all value flowing into Iran’s crypto ecosystem in late 2025,with the corps channeling over $3 billion through digital networks over the course of that year, up from $2 billion in 2024 – a trajectory that reflects both growing sophistication and growing scale. Iran’s total crypto inflows hit a record $7.8 billion in 2025. More broadly, Chainalysis data shows the value received by sanctioned entities globally surged 694% in 2025, reaching $104 billion – a figure the firm attributes in large part to Iranian activity.
The Strait of Hormuz Toll
Among the specific mechanisms Chainalysis has documented is what the industry is now calling a “Hormuz crypto toll.” Iran has codified a Strait of Hormuz Management Plan under which commercial vessels – primarily oil tankers – are charged approximately $1 per barrel or up to $2 million per ship for safe passage through a corridor that carries around 20% of global oil trade. Payments are demanded in Bitcoin, USDT, or Chinese yuan via the CIPS system, deliberately bypassing the SWIFT network. After a confirmed payment, vessels receive a secret IRGC-issued passcode by radio to transit near Larak Island.
Despite Hosseini’s public reference to Bitcoin specifically, Chainalysis analysts expect stablecoins to be the dominant instrument in practice. The reasoning is straightforward: Bitcoin is volatile and, based on documented IRGC behavior, has been used primarily by Iranian cyber actors for ransomware operations rather than large-scale commercial flows. Stablecoins, pegged to the dollar, preserve value and provide the liquidity necessary for high-volume trade. The IRGC’s entire documented history of oil sales, weapons procurement, and proxy financing runs overwhelmingly on stablecoins – making them the more logical vehicle for a scheme of this scale.
Earlier analysis from TRM Labs had estimated the scheme carries significant revenue potential – potentially hundreds of millions per month if LNG vessels are included alongside oil tankers – figures that align with the scale of IRGC crypto activity Chainalysis has since documented.
The Enforcement Trail
The Chainalysis findings are grounded in a traceable enforcement record. In January 2026, OFAC designated crypto exchanges Zedcex and Zedxion – identified by analysts as a clearing hub for the IRGC – for operating within Iran’s financial sector. The two platforms had processed over $94 billion in total volume, primarily USDT transactions on the Tron network. OFAC simultaneously blacklisted seven specific Tron wallet addresses tied to the Zedcex network, in what marked the first direct targeting of crypto exchanges linked to an Iranian military structure.
The preceding months followed the same pattern. In September 2025, OFAC dismantled a network of front companies across Hong Kong and the UAE that had coordinated over $100 million in crypto purchases tied to illicit oil sales for the IRGC’s Quds Force. In April 2025, eight wallets were designated for facilitating nearly $1 billion in funding for Iran-backed proxies including the Houthis. Chainalysis notes that enforcement is increasingly targeting the underlying exchanges and payment processors rather than individual wallets – closing what analysts describe as the “infrastructure loophole.”
The Legal Exposure for Shipping Companies
Kaitlin Martin, senior intelligence analyst at Chainalysis, is direct about the risk for any shipping firm considering payment: the U.S. Treasury’s Office of Foreign Assets Control does not distinguish between fiat and crypto when assessing sanctions violations. Under the International Emergency Economic Powers Act, any transfer to the IRGC constitutes material support for a sanctioned entity, with consequences that include frozen assets, criminal penalties, and exclusion from the dollar-based financial system. Ignorance of who controls the receiving wallet is rarely a viable legal defense.
The compliance pressure is already moving through the industry. Insurance desks and maritime brokers are signaling they may refuse to work with companies even suspected of having paid the toll, creating reputational and commercial exposure well before any formal OFAC action.
Why Crypto Doesn’t Hide the Trail
One of the more pointed conclusions in the Chainalysis analysis is the direct rebuttal of the premise that cryptocurrency offers untraceable payments. It does not. Public blockchains are permanent, searchable ledgers, and Chainalysis notes that blockchain transparency allows regulators and compliance teams to identify shipping companies interacting with IRGC-linked wallets in near real-time – without court orders or banking intermediaries. The property that makes blockchain useful for legitimate finance is the same one that makes it a poor vehicle for sanctions evasion against an adversary equipped with professional blockchain analytics tools.
There is one structural difference between Bitcoin and stablecoins that carries direct enforcement implications here. Unlike Bitcoin, stablecoins have an issuer – and that issuer can freeze wallets. If the IRGC does rely on USDT for toll collection at scale, as Chainalysis expects, stablecoin issuers become an immediate and technically straightforward intervention point, without requiring a court order or a law enforcement operation.
A Model Others May Follow
Chainalysis analysts flag a concern that extends beyond Iran. This appears to be the first documented instance of a nation-state demanding cryptocurrency as a condition for passage through an international waterway. If the scheme proves financially viable, it offers a working template for other sanctioned regimes that control strategic chokepoints – a mechanism to extract revenue without military escalation and with a layer of financial complexity that complicates attribution, even if it does not ultimately prevent it.
