Core Event: Blacklist and Threats Over Strait Transit
On August 24, Iran’s Persian Gulf Strait Authority (PGSA) placed 45 tankers on a “Non-Compliant Vessels” list for violating Tehran’s transit rules in the Strait of Hormuz. Listed ships face fines, detention, and cargo confiscation, and vessels conducting ship-to-ship transfers with them could also be blacklisted. Companies named include ADNOC Logistics & Shipping, Navig8 Tankers, Saudi Bahri, Klaveness Ship Management, Stolt Tankers and Sinokor.
Background & Context
The Strait of Hormuz carries roughly one-fifth of global oil and LNG shipments. Traffic fell sharply after the February 28 airstrikes that opened the current U.S.–Israel–Iran conflict. Iran requires clearance and security fees for transits, while the United States has imposed a naval blockade on Iran-related shipping and is preparing a sanctions package slated for announcement on August 24.
Data & Statistics
- 45 vessels are now blacklisted.
- Kpler recorded four commodity ships crossing the strait on a recent Sunday, down from more than 130 per day before the war.
- U.S. Energy Secretary Chris Wright reported a seven-day average of over 8 million barrels of oil per day moving through the strait, compared with about 20 million barrels per day pre-war.
Official Statements & Responses
- Energy Secretary Chris Wright credited the U.S. Navy for keeping oil flowing.
- Supreme National Security Council secretary Mohsen Rezaei warned that continued “economic war” would halt all oil exports from the Gulf.
- Foreign Ministry spokesperson Esmail Baghaei cautioned that any escalation would “bring about consequences.”
On-the-Ground Reports
Iranian state media said Iraq received permission for several of its oil tankers to transit the strait after repeated requests, underscoring Baghdad’s dependence on Hormuz.
Conflicting Reports & Gaps
Sources differ on daily traffic figures: one report notes four commodity ships on a Sunday, while another cites four as the total for the same day after a prior count of 13 the day before. No source provides a complete roster of the 45 blacklisted vessels.
