Hormuz remains physically open, but normal traffic is still far away
Commercial transits through the strait are confirmed, but flows remain far below normal and security/access conditions are severe. It is not physically closed; it is operating on a highly constrained basis.
The Strait of Hormuz enters August 20, 2026 with an assessment of “OPEN · SEVERELY RESTRICTED TRANSIT” and medium confidence; physical passage confirmed, traffic reduced, risk extreme. Commercial transits through the strait are confirmed, but flows remain far below normal and security/access conditions are severe. It is not physically closed; it is operating on a highly constrained basis. Today's edition separates what is happening on the water from political statements and market reaction.
What changed since yesterday
The headline state is unchanged, but some dimensions have moved: access, political/legal framework. This prevents two days with the same label from being treated as operationally identical.

What to watch over the next 24 hours
- Whether commercial crossings recover for several consecutive days or fall again towards a near-total pause.
- New JMIC/UKMTO advisories, confirmed attacks, interference or changes in escorts and naval presence.
- Changes in imposed routes, inspections, permissions, sanctions, insurance or selective passage conditions.
- The behaviour of shipowners, insurers and major cargo interests: a sustained return of private operators would be stronger evidence of normalisation than a political statement.
