Iran has announced a new position regarding commercial shipping through the strategically vital Strait of Hormuz, stating that “non-hostile” vessels will be allowed to pass without obstruction.
In a letter sent on Tuesday (March 24) to member states of the International Maritime Organization, Iran’s Foreign Ministry outlined its policy amid heightened regional tensions.
Conditional Passage for Ships
The letter states that Iran has imposed certain restrictions in the Strait as a precautionary measure to prevent “aggressive powers” from using the route to launch attacks against the country. However, commercial vessels categorized as “non-hostile” will be permitted to transit, provided they maintain communication and coordination with Iranian authorities.
‘Hostile’ Countries Identified
Iran identified the United States and Israel—along with countries supporting them in the ongoing conflict—as “hostile.” Commercial ships linked to these nations will not be considered “non-hostile” and may face restrictions while passing through the Strait.
A copy of the letter has reportedly been distributed to all IMO member states, according to the Financial Times.
A Key Global Energy Corridor
The Strait of Hormuz connects the Arabian Sea and the Persian Gulf, making it one of the world’s most important energy routes. Approximately 20% of global oil and liquefied natural gas shipments pass through this narrow waterway each day.
Often referred to as the “gateway to global energy,” it is essential for transporting oil from Middle Eastern producers to international markets.
Rising Security Concerns
Since the outbreak of conflict on February 28 involving the U.S. and Israel, Iran’s Islamic Revolutionary Guard Corps has issued warnings to vessels operating in the area. Several ships have reportedly been attacked.
According to the UK Maritime Trade Operations, more than a dozen oil tankers have been targeted since late February.
Impact on Global Energy Supply
The ongoing security tensions have disrupted shipping through the Strait, contributing to energy supply concerns in several countries and increasing volatility in global oil markets.
