Overview of the New Vetting System
Iran is developing a vetting and registration system for ships transiting the Strait of Hormuz, marking a shift towards a "selective" blockade of this critical waterway. According to reports from Lloyd’s List, this system will require vessels to submit detailed information regarding ownership and cargo destinations to the Islamic Revolutionary Guard Corps (IRGC) prior to transit. The initiative comes amid a significant decline in maritime traffic, which has dropped by 95% since the onset of hostilities involving the United States and Israel against Iran on February 28, 2026.
Impact on Maritime Traffic
Despite the blockade, a limited number of vessels, primarily flagged to India, Pakistan, and China, have successfully navigated the Strait. Reports indicate that at least nine ships have utilized a newly established "safe corridor" through Iranian territorial waters, with one tanker reportedly paying a fee of $2 million for passage. This corridor is under the supervision of the IRGC, which conducts visual vetting of vessels. However, many ships have opted to turn off their automatic identification systems or declare their Chinese credentials to mitigate risks.
Economic Implications and Criticism
Experts, including maritime law specialist Alex Mills, express skepticism regarding the long-term viability of Iran's new system. Mills notes that while it may provide a temporary solution, concerns about safety, insurance, and existing sanctions could deter shipping companies from utilizing this route. He emphasizes that without confidence in the economic benefits and safety of this corridor, many firms may choose not to operate in these waters, as maritime supply chains are typically planned months in advance.
Official Statements and Responses
Iran's Foreign Minister Abbas Araghchi has stated that while the Strait is "open," it remains "closed to our enemies," reflecting a de-escalation from earlier IRGC threats against vessels attempting to transit. Additionally, Iranian officials are considering legislation to impose transit fees on vessels using the Strait, which would serve as a form of sanction against Western powers.
Conflicting Reports and Gaps
There are discrepancies regarding the number of vessels successfully transiting the Strait. While some reports indicate that only around 15 vessels have navigated the waters recently, others claim that at least nine have used the new corridor. Furthermore, the economic implications of the new vetting system remain uncertain, with varying opinions on its potential impact on global shipping.
What's Next
As the conflict continues, Iran is expected to formalize its transit fee structure and further develop its vetting system. The situation remains fluid, with ongoing discussions between Iran and several countries, including India, Pakistan, and China, regarding safe passage through the Strait of Hormuz. The broader implications for global energy markets and shipping routes will likely unfold as the conflict progresses.
