Iran Formally Establishes 'Persian Gulf Strait Authority,' Declaring Transit Without Permission Illegal

Tehran has institutionalized its control over the Strait of Hormuz by launching a state agency that requires commercial vessels to purchase transit permits. The move forces global shipping companies to choose between violating US sanctions or risking Iranian military confrontation.

On May 5, 2026, the Islamic Republic of Iran formally activated the Persian Gulf Strait Authority (PGSA), a new government agency designed to transform military control of the world's most critical energy chokepoint into a permanent administrative toll system. The move requires commercial vessels to apply for transit permits and pay fees—often routed through cryptocurrency to evade Western financial networks—in exchange for safe passage through the Strait of Hormuz.[1][6]

The establishment of the PGSA represents a strategic shift by Tehran, moving from wartime physical blockades to institutionalized regulatory control. By charging tolls for transiting the international waterway, the Islamic Revolutionary Guard Corps (IRGC) guarantees ships will not be openly attacked. As of early June, over 300 shipping companies had already applied for permits, primarily those servicing Asian destinations such as China, India, and the United Arab Emirates.[1]

The United States has aggressively rejected the new framework. The US Treasury's Office of Foreign Assets Control (OFAC) sanctioned the PGSA shortly after its creation, characterizing it as a mechanism for the IRGC to extract revenue through state-sponsored coercion. Treasury Secretary Scott Bessent warned that the Trump administration is preparing unprecedented economic isolation measures against Tehran to break its grip on the corridor.[2][6]

The strategic and economic stakes of the Persian Gulf Strait Authority's transit framework.

Despite US pressure and a naval blockade that has redirected at least 62 commercial vessels, Iranian officials maintain that their control over the strait is absolute. Rear Admiral Ali Ozmaei, commander of the IRGC Navy, stated that no movement escapes Iranian forces and that the strait remains closed to unauthorized traffic.[2][4]

The diplomatic clash escalated further in mid-August when US President Donald Trump claimed on social media that the United States had "total control" over the Strait of Hormuz, describing the US naval presence as a "wall of steel."[3]

Iranian military officials swiftly dismissed the US president's claims as fabrications. Ebrahim Zolfaghari, spokesperson for Iran's central military command, asserted that no commercial ship or tanker has the possibility of safe passage without the direct permission and supervision of Iranian armed forces.[3]

Iranian military officials swiftly dismissed the US president's claims as fabrications.

Concurrently, Iran's parliament advanced a strategic action plan designed to formally bar vessels and equipment belonging to the US, Israel, and other designated hostile nations from passing through the waterway. Valiullah Bayati, a spokesperson for the parliament's internal affairs committee, confirmed that the general outline of the plan had been approved.[2]

The Strait of Hormuz serves as the critical maritime artery for energy exports to Asia.

Amid the standoff, regional diplomacy has yielded a parallel track. Iranian Foreign Ministry spokesman Esmaeil Baghaei announced that Tehran and Muscat have reached an agreement on a shipping route map for the Strait of Hormuz following weeks of technical negotiations.[4][5]

The Iran-Oman arrangement aims to establish safe navigation routes while preserving the sovereignty of both coastal states. However, Baghaei emphasized that the full restoration of security and the resumption of normal commercial shipping depend entirely on the lifting of the US naval blockade and an end to what Tehran describes as illegal US military threats.[4][5]

The global shipping industry now faces a fractured maritime environment. With 20 percent of the world's oil supply dependent on the Strait of Hormuz, the competing frameworks—Iran's PGSA toll system and the US-led naval deterrence—force operators to navigate not only physical risks but also severe legal and financial liabilities.[1][2]

Key points

  • Iran established the Persian Gulf Strait Authority (PGSA) to mandate transit permits and tolls for ships entering the Strait of Hormuz.
  • Over 300 shipping companies have applied for permits, primarily those servicing Asian markets.
  • The US Treasury sanctioned the PGSA, warning of unprecedented economic isolation against Tehran.
  • Iran and Oman reached an agreement on a shipping route map, though Tehran insists full reopening requires an end to the US naval blockade.
  • Iran's parliament advanced a strategic plan to formally ban US and Israeli vessels from the waterway.

Viewpoints in depth

Compliance with the PGSA Framework

Shipping companies and regional actors accepting Iran's toll system to guarantee safe passage.

For: Guarantees physical safety from IRGC harassment and maintains access to vital Asian and UAE markets. Against: Violates US OFAC sanctions, exposing companies to severe financial penalties, and legitimizes Iranian administrative control over international waters. Evidence: Over 300 shipping companies, primarily servicing China and India, have already applied for PGSA permits. Fits well when: Vessels are flagged to non-Western nations with minimal exposure to US financial systems and prioritize immediate cargo delivery. Does not fit when: Companies have heavy US market exposure or rely on Western insurance and banking networks.

US-Led Deterrence and Rerouting

Relying on US naval protection or avoiding the Strait entirely in defiance of the PGSA.

For: Complies strictly with US Treasury sanctions and rejects the precedent of a chokepoint toll system. Against: Carries a high risk of vessel seizure or military confrontation, while rerouting adds massive logistical costs and delays to global supply chains. Evidence: US CENTCOM reports redirecting 62 commercial vessels under the current naval blockade, while the US Treasury prepares unprecedented economic isolation measures. Fits well when: Vessels are US-flagged, carry high-value Western cargo, or operate under strict compliance mandates that forbid payments to sanctioned entities. Does not fit when: Time-sensitive energy shipments to Asian markets cannot absorb the logistical penalty of avoiding the Persian Gulf.
