Iran Requires Crypto or Chinese Yuan for Ship Transit Fees

Iran has implemented a formalized toll system for vessels transiting the Strait of Hormuz, accepting payments in Chinese yuan and cryptocurrency. This system, which began deploying cryptocurrency as a payment option in mid-March 2026, represents the first instance of a nation-state utilizing crypto infrastructure as a sovereign revenue mechanism at a major maritime chokepoint.

The payment mechanism specifically utilizes stablecoins pegged to fiat currencies to facilitate transactions. According to reporting from TRM Labs, the use of cryptocurrency allows these payments to be settled quickly and outside of US correspondent banking systems, which makes the real-time interdiction of toll payments technically difficult for international regulators.

Operational Framework and Vetting

The toll system is administered through an intermediary linked to the Islamic Revolutionary Guard Corps (IRGC). To receive clearance for transit, vessel operators must submit a comprehensive set of documentation for geopolitical vetting, including:

• Vessel ownership records and flag registration
• Cargo manifests and destination ports
• Crew lists
• AIS tracking data

Following this vetting process, the intermediary assigns each nation a friendliness ranking on a scale of one to five. Once approved, operators receive a passcode broadcast via VHF, which allows them to receive an IRGC Navy escort through the waterway.

Financial Structure and Revenue

The cost of transit varies by vessel type. Reports indicate that fees for oil tankers open at $1 per barrel, while other estimates from TRM Labs suggest the IRGC may charge up to USD 2 million per vessel.

The revenue potential of this system is significant. Public estimates suggest that oil tankers alone could generate up to USD 20 million per day. If LNG vessels are included in the toll system, monthly revenue could potentially reach between USD 600 million and USD 800 million.

Institutionalization and Infrastructure

Evidence suggests this is a durable institutional shift rather than a temporary measure. The Fars news agency reported that the Iranian parliament approved a transit fee bill. Lawmaker Mohammadreza Rezaei Kouchi stated that we provide its security, and it is natural that ships and oil tankers should pay such fees.

To support these operations, Iran has established institutional infrastructure, including a command structure within the IRGC and a cryptocurrency-related facility on Qeshm Island.

Current Status and Transit Limits

While a Pakistan-brokered ceasefire took effect on April 7, 2026, Iranian government statements as of April 8, 2026, suggest the ceasefire may be in question. Despite this, the toll system remains in effect.

In addition to the financial requirements, Iran is tightening physical control over the strategic waterway. Reports indicate plans to cap daily transit at approximately 10 ships.
