Iran has blacklisted 45 commercial vessels for allegedly violating transit rules in the Strait of Hormuz, according to a social media post by the Persian Gulf Strait Authority late Sunday. The newly established Iranian agency stated it may fine, detain, or confiscate the cargo of these named tankers, as well as any vessels that engage in ship-to-ship transfers with them.
The announcement follows recent escalations in the region, including U.S. threats of strict sanctions and an ongoing naval blockade against Iran-related shipping. The Persian Gulf Strait Authority, which Iran created to manage the waterway, did not explicitly define the rules in its post, though Iranian officials have previously required transiting ships to obtain clearance and pay for security services.
The blacklist includes very large crude carriers, liquefied natural gas (LNG) tankers, and clean product vessels. Among the 45 ships are vessels owned by Saudi Arabia's Bahri, the United Arab Emirates' ADNOC Logistics and Shipping, and firms based in South Korea and Norway. The targeted shipping companies did not immediately provide comment to Reuters regarding the designation.
A person working in the global energy or shipping sector would notice these changes through increased insurance risks, potential cargo delays, and new administrative requirements. The Persian Gulf Strait Authority stated that cargo owners must monitor an updated list of non-compliant vessels. To be removed from the list, ship-owners are required to submit formal explanations to Iranian authorities, though the specific timeline for processing these requests was not reported.
The move establishes a precedent for Iranian administrative control over one of the world's most critical maritime chokepoints during active hostilities. While U.S. Secretary of Energy Chris Wright stated on Friday that the U.S. Navy is ensuring oil continues to flow, the Iranian blacklist threatens knock-on effects for the insurance market and the legality of ship-to-ship transfers. What happens next depends on how shipping firms respond to the demand for Iranian clearance and whether the U.S. proceeds with the "toughest sanctions in history" mentioned by officials on August 20.
