Iran floats $40 billion Hormuz tolling scheme as tankers turn back from Omani corridor

Tehran is preparing to pitch what would amount to a sovereign pay-to-pass regime for the Strait of Hormuz, estimating it could generate as much as $40 billion a year by charging commercial vessels for security, safety and environmental services, the Wall Street Journal reported on 25 June 2026. Within hours of that figure circulating, Bloomberg reported that at least three ships — including two large oil tankers — attempted to leave the waterway via a route running parallel to the coast of Oman, then reversed course after instruction by Iranian authorities, according to Telegram channels citing the wire.

The pattern matters more than either data point. Iran is no longer simply threatening closure of the strait through which roughly a fifth of seaborne crude normally transits; it is sketching a price list. The proposal, and the apparent enforcement action that accompanied its leak, point to a quiet attempt to convert a chokepoint into a recurring revenue line on a national balance sheet still working under heavy sanctions.

A revenue plan dressed as a service offering

The $40 billion figure surfaced in reporting from the Wall Street Journal on 25 June, relayed by the Megatron monitoring channel, and was amplified by the Tehran-aligned Clash Report feed. Under the scheme as described, Iran would collect fees in return for three categories of service: security escort through the strait, navigational safety, and a levy framed as environmental remediation. None of the reporting reviewed here specifies a per-tonne rate or a sovereign-billing mechanism. The framing — payment in return for a defined service — is the diplomatic innovation. It gives Tehran a defensible legal posture it can carry into Omani, Chinese and Indian conversations, and it gives any government that signs up a fig leaf for routing money to a sanctioned jurisdiction.

For an Iranian budget that has spent two decades adapting to financial isolation, the ceiling is significant. $40 billion a year is a number that, if even partially realised, would re-order Tehran's fiscal arithmetic — equivalent to several times the country's typical annual oil export receipts net of sanctions discount. It also sets up a direct test of how much the international shipping industry, and the insurers and commodity traders that underwrite it, is willing to pay to keep barrels moving through a 21-mile-wide corridor.

The Omani corridor and the tankers that turned around

The operational backdrop is the parallel coastal route. According to Bloomberg reporting circulated on 25 June by the Liveuamap and War and Force witness channels, several vessels attempting to exit the strait via a new evacuation route running along Oman's coast appeared to make U-turns after being instructed by Iranian authorities to change course. The Tasnim news channel, an outlet close to Iran's security establishment, framed the same episode as a withdrawal of oil tankers from the route parallel to Oman's coast. The two Iranian-aligned and one Western-wire description of the same event agree on the count — at least three ships, two of them oil tankers — and disagree on the framing: enforcement or voluntary withdrawal.

What the reporting does establish is that the parallel corridor is not functioning as the open detour shipping markets had begun to price in. If Iranian vessels can dictate course corrections on a route nominally under Omani coastal jurisdiction, the marginal value of that detour collapses. That reopens the central question of the past two weeks: does the strait operate as a single controlled conduit, or as a navigable system with alternatives? The events of 25 June, on the available evidence, point toward the former.

A coordination call, not a crisis call

The same afternoon, Iranian Foreign Minister Abbas Araghchi and Oman's foreign minister held a call explicitly framed around coordination on Strait of Hormuz traffic, according to a Reuters dispatch at 15:40 UTC. The choice of Oman is not incidental. Muscat is the only Gulf monarchy that has maintained working diplomatic ties with Tehran across the full arc of regional tensions and is the geographic reference point for the parallel coastal route now in dispute. The language of the call — coordination, not de-escalation, and certainly not condemnation — is consistent with a posture in which both governments expect traffic to continue, and expect Iran to retain a degree of operational say over how it does.

A counter-reading is available. The Reuters wording is thin by diplomatic-release standards. It does not confirm Iranian acceptance of Omani-led management of the parallel corridor, nor does it signal that Tehran has agreed to refrain from directing traffic. The call could equally be read as Tehran and Muscat aligning on a managed process in which Iranian instruction of vessels is treated as a normal feature, not a violation. The sources reviewed here do not resolve the ambiguity.

What a $40 billion corridor would actually do

If Tehran operationalises even a fraction of the figure reported by the Wall Street Journal, the consequences run in several directions at once. Insurers would reprice war-risk premia, which are already elevated. Major commodity traders would widen the spread between Brent and Middle East benchmarks. China and India — the two largest customers for crude moving through the strait — would face a direct, recurring cost that they would either absorb, pass through, or seek to route around via Russian and West African barrels. And a precedent would be set: a sanctioned state extracting recurring fees from global commerce through geography that no one else can bypass.

There is also a plausible alternative read. The $40 billion ceiling may be diplomatic positioning rather than policy. Leak a high number; observe how tanker behaviour, insurance markets, and foreign ministry calls respond; then negotiate from a number that is lower but still significant. Tehran has form here — the 2019 episode in which the IRGC briefly seized a British-flagged vessel produced no lasting toll regime, but it did produce a long tail of insurance and routing changes that benefited Iranian-aligned actors. The current episode is a much larger version of the same logic.

What we do not know

The sources reviewed here do not specify whether the $40 billion figure has been formally communicated to any foreign government, whether it represents gross or net revenue, or which Iranian ministry would administer the levy. The reporting does not describe any specific fee schedule, nor does it identify a payment mechanism that would operate under existing US and EU sanctions. The number of vessels that turned back is given as "at least three" by Liveuamap citing Bloomberg and as "several" by the War and Force witness channel citing the same wire; the difference is small but real, and matters for anyone trying to assess whether the episode was a single instruction or a wider pattern. The Reuters read-out of the Araghchi–Omani call does not include a direct quotation, and the precise status of the parallel route after 25 June 2026 — open, restricted, or suspended — is not confirmed by any of the available reporting.

The structural story, on the evidence, is this: Iran is testing whether geography plus naval capacity can be converted into a recurring financial claim on the global economy. The world's shipping and insurance markets will price the answer long before any negotiating table does.

How Monexus framed this: the wire cycle on 25 June paired a high-ceiling revenue claim from Tehran with an enforcement signal on a secondary corridor. We treated the revenue number as a negotiating anchor and the Omani-corridor turnbacks as the operationally significant data point — and flagged the limits of what the available reporting actually establishes.
