Iran's Persian Gulf Strait Affairs Authority (PGSA) has updated its list of violating vessels, warning of restrictions for non-compliant ships and those cooperating with them.

The PGSA announced an updated list of vessels deemed in violation, with entries partly based on public submissions. The authority stated that non-compliant vessels face fines, detention, or confiscation, and advised cargo owners to check the list to avoid issues, especially since the Strait of Hormuz was closed following alleged US-Israeli aggression.
Imagine there's a very important road for ships, like a big highway, called the Persian Gulf. Iran, the country next to it, has made a list of ships that aren't following its rules. If a ship is on this list, it might get stopped, fined, or even taken away. Iran is doing this because it feels like other countries, like America and Israel, have been aggressive, making the big ship highway unsafe. So, they're telling all the other ships and their owners to check this list carefully before they travel, or they might get into trouble.
Analysis
Persian Gulf Strait Affairs Authority
The Persian Gulf Strait Affairs Authority (PGSA) has taken a significant step by updating its list of vessels deemed to be in violation of its regulations. This action underscores Iran's intent to enforce its maritime rules within the critical Persian Gulf waterway. The PGSA explicitly stated that some of the information leading to these listings was voluntarily submitted by the public, indicating a crowdsourced element to their enforcement efforts and a desire to involve citizens in monitoring maritime activity.
The authority's website now serves as a crucial reference point for all maritime stakeholders. It clearly outlines the severe consequences for non-compliant vessels, which include fines, detention, or even confiscation. This move is designed to deter vessels from operating in ways that Iran deems unacceptable, thereby asserting its sovereignty and control over the strategic maritime chokepoint. The PGSA's advisory to cargo owners to review the list before chartering vessels highlights the potential for widespread disruption to commercial shipping.
February 28
The context for this updated list is deeply rooted in recent geopolitical tensions, specifically the closure of the Strait of Hormuz following what Iran describes as "unprovoked American-Israeli aggression" on February 28. This date marks a critical turning point, as it led to the suspension of passage through the vital chokepoint. The PGSA's actions are therefore not merely administrative but are directly linked to a broader security posture adopted by Iran in response to perceived external threats.
The closure of the Strait of Hormuz, a conduit for a significant portion of the world's oil supply, has profound implications for global energy markets and international trade. By linking the vessel violations to this aggressive backdrop, Iran frames its enforcement as a defensive measure. This narrative suggests that the updated list and associated restrictions are part of a larger strategy to secure its maritime borders and respond to what it views as hostile actions by the United States and Israel.
info@pgsa.ir
For vessels that find themselves on the PGSA's list, a formal process has been established for requesting removal. The authority directs affected parties to submit a formal application with justifications to info@pgsa.ir. This provision, while offering a pathway for recourse, also centralizes control over the delisting process within the PGSA, ensuring that all requests are vetted directly by the Iranian authority.
Furthermore, the PGSA has introduced a stringent rule: any vessel found cooperating with listed vessels through activities such as ship-to-ship (STS) transfers or transshipment will also be added to the list. This measure aims to prevent circumvention of the restrictions and to broaden the scope of enforcement, effectively creating a secondary layer of compliance. The email address serves as the official channel for engaging with the PGSA on these critical matters, emphasizing the formal and controlled nature of their maritime governance.
Key points
- Iran's Persian Gulf Strait Affairs Authority (PGSA) has updated its list of violating vessels.
- Non-compliant vessels face restrictions including fines, detention, or confiscation.
- The PGSA advises cargo owners to review the list before chartering vessels to avoid issues.
- Vessels cooperating with listed vessels (e.g., via ship-to-ship transfers) will also be added to the list.
- The Strait of Hormuz was closed on February 28 following alleged 'unprovoked American-Israeli aggression' against Iran.
The updated list of violating vessels and the threat of fines, detention, or confiscation could significantly disrupt international shipping in the Persian Gulf, leading to increased costs and delays for cargo owners. This move, coupled with the ongoing closure of the Strait of Hormuz due to alleged US-Israeli aggression, risks escalating regional tensions and potentially leading to further confrontations in a critical global waterway.
Market signals
- OIL Restrictions and aggression in the Persian Gulf increase supply route risks for oil, potentially driving prices higher.
