Hormuz traffic remains severely constrained despite a new diplomatic opening
Official incident data and commercial transit observations show that safe, predictable passage has not returned.

Assessment
What the evidence currently supports
Only nine vessels transited the Strait of Hormuz on 2 August, most via an Iranian-controlled route, according to Kpler data cited by AP. The International Maritime Organization's live incident register listed 63 confirmed Middle East maritime incidents and 17 seafarer deaths through 28 July. Diplomacy may improve access, but the latest public evidence does not show that safe, predictable, and insurable passage has been durably restored.
IMO's incident ledger cutoff was 28 July 2026.
Confirmed by IMO across the listed Middle East maritime incidents.
Change log
What changed
- Weekly ship traffic fell from 82 vessels during 13–19 July to 39 during 20–26 July, according to Lloyd's List Intelligence data cited by AP.
- IMO's confirmed incident ledger reached 63 incidents and 17 seafarer fatalities by 28 July.
- The 2 August transit observation showed some movement, but at a volume and routing pattern inconsistent with normal passage.
Open questions
What remains uncertain
- AIS and commercial tracking can undercount ships operating with disabled, degraded, or manipulated signals.
- IMO's confirmed-incident total establishes occurrence, not responsibility for every incident.
- A one-day count of nine vessels is not evidence of a durable reopening.

Read the scoring method
Evidence quality weighs source authority and directness; corroboration rewards independent agreement; recency reflects how closely sources track the latest material change; source diversity rewards different institutions, geographies, and source classes. The displayed score is the rounded weighted composite: 35%, 30%, 20%, and 15% respectively.

01supported97/100
IMO had confirmed 63 Middle East maritime incidents and 17 seafarer fatalities through 28 July.
The figures come directly from IMO's maintained incident ledger and are consistent with the organization's contemporaneous safety statements.
The ledger can be revised as incidents are confirmed or reclassified.
02supported90/100
Available traffic observations did not show a durable return to normal Hormuz passage by 3 August.
AP cited both a sharp week-over-week traffic decline and only nine transits on 2 August, while IMO continued to document acute safety risks.
Traffic can change quickly, and commercial observations are snapshots rather than a complete registry.
