On 2 September 2026, regional and industry reporting described a further tightening of Iran’s administrative grip on Hormuz transit. Sources said the Persian Gulf Strait Authority (PGSA) added roughly 11 additional tankers and commodity carriers to its non-compliant vessels list, taking the roster toward about 56 ships facing fines, detention or confiscation risk if they attempt passage without Tehran’s approval. The expansion layers paperwork and seizure risk onto an already kinetic waterway.
The same news cycle carried Iranian Revolutionary Guard messaging that two oil tankers had encountered sea mines and been disabled while trying to transit Hormuz, with claims of fire and crew disembarkation before or around the incidents. Independent verification and vessel identities were less clear in open Western reporting than the PGSA list expansion, but the dual narrative — blacklist growth plus mine casualties — is designed to deter unauthorised commercial use of the strait.
Operators must therefore screen both physical threat advisories and PGSA list status before fixing. A ship that is “only” kinetically exposed may still be administratively radioactive if listed; conversely, unlisted ships remain exposed to mines and projectiles. STS with listed tonnage can also create contagion risk under earlier PGSA warnings.
What Operators Should Note
- Screen every Gulf fixture against the latest PGSA IMO list before fixing or bunkering.
- Avoid STS with blacklisted ships that could infect otherwise clean tonnage.
- Treat IRGC mine claims as a reason to refresh mine-danger graphics, even if details are contested.
- Add seizure/confiscation language to charter parties for Hormuz-adjacent employment.
- Brief masters that administrative interception can follow kinetic survival on the same voyage.
Regulas Shipping will monitor PGSA list growth and any confirmed mine-casualty cases affecting commercial fleets.
