This analysis evaluates Iran’s establishment of the Persian Gulf Strait Authority (PGSA) as a strategic fait accompli designed to institutionalise administrative control over the Strait of Hormuz and force a new baseline in negotiations with Washington.

It examines how Tehran is utilising a sanctions-resistant cryptocurrency toll regime and sophisticated information warfare to transform a wartime physical chokepoint into a permanent regulatory asset that challenges US leverage.

Context

On 5 May 2026, the Islamic Republic of Iran (IRI) founded The Persian Gulf Strait Authority – PGSA (Nahad-e Modiriate Abrah-e Khalij-e Fars), a legal authority and official representative body for managing transit through the Strait of Hormuz.

The US Treasury’s Office of Foreign Assets Control (OFAC) sanctioned the PGSA, characterising it as a renewed attempt by the Islamic Revolutionary Guard Corps (IRGC) to extract revenue from its campaign of state-sponsored terrorism. Treasury Secretary Scott Bessent framed the move as further evidence that the Economic Fury pressure campaign had left the Iranian regime financially strained and increasingly reliant on coercive mechanisms to generate income.

The PGSA responded defiantly, rejecting the designation and inverting its framing: the authority portrayed being sanctioned by Washington as a validation of its conduct rather than a rebuke, and dismissed the measure as an instrument wielded by an administration it accused of endorsing maritime piracy. It further asserted that dominion over the Strait of Hormuz, having eluded the United States on both the battlefield and at the negotiating table, would equally resist any attempt to achieve it through financial coercion.

Tehran has delineated the controlled maritime zone as the area between the line connecting Kuh-e Mubarak in Iran to the south of Fujairah in the UAE at the eastern entrance of the Strait, and the line connecting the tip of Qeshm Island in Iran to Umm Al-Quwain in the UAE at the western entrance. In other words, it claims authority over the entire breadth of the waterway, encompassing both the Iranian and Emirati sides.

The toll regime under the PGSA could cost international shipowners up to $2 million per passage, payable in Bitcoin or yuan, creating a binary compliance choice, since payment is strictly prohibited by the US Office of Foreign Assets Control and sanctionable under US law.

Beyond tolls, Iran’s Finance Ministry also wants to begin offering an insurance scheme for navigating the Strait, paid in cryptocurrency, accessible to Iran-linked vessels facing difficulties obtaining coverage on the global market.

The PGSA issued a document titled “Ship Information Declaration”, a form containing over 40 questions requiring vessels to provide their name, identification number, any previous names, country of origin and destination. Vessels wanting to transit receive an email from the official address info@PGSA.ir containing Iran’s transit regulations.

Five Arab Gulf states formally opposed the establishment of the PGSA through an official letter, rejecting the IRI’s attempt to manage and control the passage of vessels through the Strait of Hormuz. Notably, Oman, which has been mediating between the US and Iran, was not among the signatories.

The letter warned that “any acceptance or recognition of Iran’s proposed route and the PGSA as an alternative option could create a dangerous precedent”. The International Maritime Organisation (IMO), the UN’s shipping body, had previously stated that charging tolls for passage through the Strait of Hormuz is unacceptable.

Why Does It Matter?

The PGSA as a fait accompli strategy. Iran’s establishment of it is not primarily an operational maritime measure but a legal and political instrument designed to change the negotiating baseline. By creating a bureaucratic body with formal jurisdiction claims, the IRI is attempting to transform a wartime closure into a permanent regulatory regime. The strategic logic is clear: if the PGSA is accepted in practice, even informally, it converts Tehran’s de facto control of the Strait into a sovereign administrative norm, one that would survive any ceasefire and persist through subsequent negotiations.

The PGSA does not resolve the question of who controls the Strait of Hormuz, it pre-empts it. By creating an administrative body before a deal is signed, Tehran ensures that any agreement requiring the Strait’s reopening must also implicitly address the PGSA’s status. This forces the US into a position where accepting the MOU without explicitly dissolving the PGSA amounts to a tacit legitimation of Iranian maritime authority.

Multiple credible sources confirm that payments accepted by IRGC-linked intermediaries include Chinese yuan routed through Kunlun Bank via the CIPS system (outside SWIFT), Bitcoin, and potentially USDT stablecoins. The fee structure reported (approximately $1 per barrel, yielding up to $2 million per tanker transit) is consistent across sources, though no official public tariff has been published. Iran’s parliament formally codified the system in the “Strait of Hormuz Management Plan”, approved March 30–31.

Why yuan and crypto and why it matters? IRI’s choice of payment currencies is strategically deliberate. The yuan, routed through CIPS, bypasses the US dollar correspondent banking system entirely, reinforcing Beijing’s parallel financial infrastructure. Bitcoin, by design, has no centralised issuer and cannot be easily seized or blocked, a critical feature given US Treasury’s active seizure of Iranian crypto assets (approximately $1 billion seized as of late May).

USDT and USDC stablecoins include backdoors allowing asset freezes, which makes them less suitable; Bitcoin’s irreversibility is the key advantage. Iran’s crypto ecosystem was valued at $7.8 billion in 2025, and the IRGC has routed approximately $1 billion through offshore stablecoin infrastructure since early 2026.

The Hormuz toll system deploys the same sanctions-evasion rail, transforming pre-existing financial architecture into a real-time state revenue mechanism. For decision-makers, the implication is that financial pressure alone is insufficient: the sanctions infrastructure does not reach the Bitcoin layer and tracking capabilities do not equate to the ability to block payments.

Nevertheless, while the US cannot block a peer-to-peer Bitcoin transaction, the US Treasury has actively seized over $1 billion in Iranian-linked crypto assets by targeting the off-ramps, centralised exchanges, and nested regional brokers. The rail is sanctions-resistant, but not completely bulletproof.

The IRI has effectively created a dual chokepoint: one physical (the Strait), one financial (the crypto toll rail). Resolving the first through a deal does not dismantle the second, the IRGC retains both the capability and the revenue model regardless of whether the PGSA is formally dissolved.

The PGSA fits precisely within IRI’s 2026 information strategy, which has been characterised by three recurring patterns: first, the assertion of sovereign normalcy, presenting what are acts of wartime coercion as routine administrative processes (such as bureaucratic forms and maps of controlled zones), to generate legitimacy through the optics of governance rather than conflict; second, victimhood inversion, framing US sanctions and the naval blockade as piracy and aggression, while presenting the PGSA as a defensive legal instrument.

The PGSA’s X account response to OFAC sanctions, calling being sanctioned “a sign of positive performance” and accusing the US president of “boasting of piracy”, is textbook. Third, targeted wedge messaging: Iran has explicitly warned that countries complying with US sanctions “will face difficulties crossing the Strait”, while allowing India-flagged vessels to transit in coordinated clusters following bilateral engagement outside the US-led coalition framework. This directly targets the GCC and Asian states whose economic interests diverge from Washington’s strategic preferences. This strategy adds to the AI-amplified information warfare, which has lately become a key dynamic.

Washington’s primary leverage instruments (the naval blockade, OFAC sanctions, and Economic Fury) have demonstrably reduced Iranian oil flows. However, several structural limitations are visible. The crypto payment rail represents a genuine enforcement gap: OFAC can designate the PGSA, but cannot technically block Bitcoin payments made in seconds, as described by Iran’s own spokesperson. The US position is also complicated by domestic economic pressure, as reflected in congressional voices (including from Trump’s own party) calling for a short-term deal. Furthermore, Trump’s last-minute additional demands (on nuclear enrichment, the HEU stockpile, and asset unfreezing) injected new uncertainty after they reportedly reached a tentative agreement.

The PGSA’s insurance scheme (Hormuz Safe, a Bitcoin-based maritime insurance platform launched mid-May) creates a self-contained financial ecosystem that could allow Iran to maintain a functional (if reduced) shipping industry regardless of Western insurance market exclusion.

The US and China issued a rare joint statement at the May 2026 Beijing summit affirming that the Strait of Hormuz must remain open under international law and that no tolls are permissible. This alignment, if sustained, is Iran’s most significant diplomatic constraint, as it denies Tehran the China card as a legitimising partner for the PGSA regime.

On the other hand, on 2 May 2026, China’s Ministry of Commerce operationalised its blocking statute framework (originally passed on paper back in 2021) to legally forbid Chinese entities from recognising, enforcing, or complying with specific US secondary sanctions.

Outlook

The PGSA is best understood not as a maritime administration body but as a negotiating position formalised in institutional form, a mechanism designed to ensure that any deal to reopen the Strait of Hormuz comes with an implicit recognition of Iranian sovereign prerogatives over the waterway.

Whether or not the PGSA survives a final agreement, its creation has already shifted the baseline: Iran has demonstrated both the will and the technical capacity to monetise the Strait through sanctions-resistant financial channels.

The US-China alignment on Hormuz freedom of navigation represents the most significant constraint on Tehran’s ambitions, but it has not yet been translated into coordinated pressure.

The content of a peace deal between Tehran and Washington remains difficult to predict, as both sides continue to use rhetoric designed primarily to satisfy their domestic supporters.
