Iran Implements New Regulations for Vessels in the Strait of Hormuz
Introduction of New Vessel Regulations
Iran has initiated a formal application procedure for ships wishing to navigate through the Strait of Hormuz, intensifying its efforts to exert authority over this crucial maritime route amid ongoing tensions with the United States and Israel. The newly established Persian Gulf Strait Authority (PGSA) has released a document titled “Vessel Information Declaration,” which outlines the requirements for vessels seeking safe passage. Ships must complete and submit this form to obtain permission, or they risk potential attacks.
Requirements for Vessel Passage
The declaration form necessitates comprehensive information from ship operators, including:
- Vessel name, identification number, and any previous names
- Country of origin and destination
- Nationalities of owners, operators, and crew
- Detailed cargo information
This information must be sent via email to the PGSA ahead of time. Iranian officials have cautioned that any incomplete or incorrect submissions will be the applicant's responsibility, with potential repercussions. Once granted approval, vessels are assigned a specific route near the Iranian coast, between Kish and Larak islands.
Strategic and Economic Implications
By establishing the PGSA and formalizing these regulations, Iran aims to transform its temporary disruption of the strait into a lasting strategic advantage. The Strait of Hormuz is a vital passage for approximately one-fifth of the world’s oil and liquefied natural gas. Control over this route provides Tehran with significant leverage over global energy markets and neighboring nations. Supreme Leader Mojtaba Khamenei has called for a “new regional and global order” led by a “strong Iran,” emphasizing the need to minimize foreign interference. Iranian officials have indicated that the closure of the strait could be used as leverage and that the new regulations could generate revenue for post-war reconstruction efforts. Reports indicate that Iran may charge vessels up to $2 million for passage, although it is unclear if all approved ships are subject to this fee.
Decline in Shipping Traffic
Prior to the conflict, the strait experienced an average of around 120 vessel transits daily. However, in the week ending May 3, 2026, only 40 ships made the crossing. As of May 7, marine traffic data indicated a near-total halt in tanker and freight movement through this critical chokepoint. Approximately 1,000 vessels and 20,000 seafarers remain stranded in the Persian Gulf, enduring significant hardships. Maritime experts emphasize that civilian mariners find themselves caught in a geopolitical struggle beyond their control.
Global Reactions and Risks
The United States has expressed strong opposition to Iran's control over the strait. The U.S. Treasury Department has warned that any payments made to Iran or the Islamic Revolutionary Guard Corps (IRGC) for passage are prohibited for American individuals and entities, potentially leading to sanctions. Some nations, including India and Pakistan, have reportedly engaged directly with Iran to secure safe passage for their flagged vessels. Nevertheless, many shipping companies are opting to avoid the route altogether due to the risks of attacks or legal consequences.
Wider Implications
Iran’s decision to formalize its control over the Strait of Hormuz marks a significant shift. What began as a wartime strategy now seems to be an effort to establish a long-term new normal, potentially leading to a permanent decrease in the volume of oil and gas transiting through the strait and altering global energy security. Analysts caution that even if some traffic resumes under Iranian oversight, transits may only reach 40–50% of pre-war levels. This would have enduring effects on energy prices, global supply chains, and economic stability in Asia and Europe. The situation remains dynamic as diplomatic efforts to address the broader conflict continue. Currently, Iran’s new regulations have further complicated navigation in one of the world’s most crucial maritime chokepoints.
