The Persian Gulf Strait Authority (PSGA) has declared the Strait of Hormuz totally closed, stating the waterway will remain shut until the regional situation stabilizes.
The authority, which manages navigation in the critical chokepoint, said that once calm is restored, permit applications will be reviewed according to the established schedule.
S&P Global Ratings had previously warned that the return to pre-conflict normalcy would be a costly and uneven process, even if the waterway was technically open.
The announcement directly contradicts statements from US President Donald Trump, who insisted earlier on Saturday that the strait remains open following recent military strikes on Iran.
The conflicting signals create immediate uncertainty for global energy markets, as the strait handles roughly a fifth of the world's oil consumption.
Handelsavisen's archive notes that while the strait had been officially reopened to navigation in recent days, vessel traffic remained heavily constrained.
