The IRGC built a customs authority, not a blockade. The infrastructure is designed for permanence, and the currency is yuan.

Key takeaway

Iran built a customs authority, not a blockade; the infrastructure is permanent.

the strait of Hormuz toll system has matured from improvised blockade into something closer to a functioning customs authority , . Claims Journal and Bloomberg detail the mechanics: $1 per barrel paid in yuan or stablecoins. A Very Large Crude Carrier carrying two million barrels pays roughly $2 million per transit.

The IRGC's Hormozgan Provincial Command runs background checks on all vessels. Five tiers of country classification determine access. Ships must raise the flag of a deal-country, broadcast passcodes over VHF radio, and receive an IRGC patrol escort through the corridor. Some vessels are required to change flag registration entirely. Pakistan has secured deals for 20 vessels.

Weekly transits have risen to 53, up from 36 the previous week, driven by bilateral exemptions: the Philippines , France, Japan , Oman, and Iraq . But pre-war volume was roughly 966 transits per week. The recovery runs through Tehran's licensing desk. Each new deal normalises Iran's sovereignty claim over international waters. Ali Vaez of the International Crisis Group assessed that Hormuz control is much more potent than even a nuclear weapon. The yuan, not the dollar, is the currency of this chokepoint.

At $1 per barrel, the IRGC's annual revenue from Hormuz tolls, if pre-war volumes resumed, would exceed $7 billion. Even at current reduced volumes, the toll generates hundreds of millions annually. The stablecoin payment option creates a sanctions-resistant financial channel. This is a new revenue stream for the IRGC that exists independently of any ceasefire agreement.

Deep Analysis

In plain English

Iran is not just blocking ships; it has built a full toll system with security checks, country rankings, and digital payments in Chinese currency. Ships pay roughly $2 million each time they pass through. This looks like a permanent operation, not a temporary war measure. It affects the price of everything that moves through the strait, which carries roughly one-fifth of global oil supply.

Deep Analysis
Root Causes

The toll system emerged from a blockade that the US threatened to break but never did (five deadline extensions).

Each unfulfilled threat gave Iran more time to institutionalise its control. The bilateral exemption pattern (Philippines, France, Japan, Oman, Iraq, Pakistan) further normalises the system by giving individual nations incentives to cooperate rather than collectively resist.

Escalation

The toll system is itself an escalation that has been normalised through repetition. Each new bilateral deal raises the cost of reversing the system. The transition from blockade to customs authority represents a permanent alteration of the maritime order in the Persian Gulf that no ceasefire framework currently addresses.

Different Perspectives
Turkey (Shakarab consideration)
Turkey (Shakarab consideration)
Ankara serves as one of two Western-adjacent Iran back-channels while Turkish national Gholamreza Khani Shakarab faces imminent execution on espionage charges in Iran. President Erdogan cannot deflect the domestic political crisis that a Turkish execution would trigger, which would force suspension of the mediating role.
Germany (Bundestag gap)
Germany (Bundestag gap)
Belgium, Germany, Australia, and France committed Hormuz coalition hardware on 18 May. Germany's Bundestag authorisation for the coalition deployment remains pending, creating a constitutional gap between the commitment announced and the parliamentary mandate required to operationalise it.
IEA and oil market analysts
IEA and oil market analysts
The IEA's $106 May Brent projection met the market in one session on 20 May as Brent fell 5.16% on diplomatic optimism. Goldman Sachs and Morgan Stanley's two-layer premium framework holds: the kinetic component compressed; the structural insurance component tied to Lloyd's ROE remains unresolved.
Hengaw
Hengaw
Documented the dual Kurdish execution at Naqadeh on 21 May, the two Iraqi-national espionage executions on 20 May, and Gholamreza Khani Shakarab's imminent execution risk. The 24-hour cluster covers two executions at one facility, the first foreign-national espionage executions, and a Turkish national whose death would suspend Ankara's mediation.
Lloyd's of London
Lloyd's of London
Hull rates stand at 110-125% of vessel value on the secondary market; the Joint War Committee has conditioned cover reopening on written ROE from the coalition or PGSA. The Majlis rial bill makes any compliant ROE structurally impossible to draft while the PGSA's yuan portal remains its operational mechanism.
United Kingdom and France (Northwood coalition)
United Kingdom and France (Northwood coalition)
The 26-nation coalition paper requires Lloyd's to see written rules of engagement before Hormuz war-risk cover reopens. The Majlis rial bill adds a second governance incompatibility on top of the unpublished PGSA fee schedule; coalition ROE cannot mention rial without conceding Iranian sovereignty over the strait.
