Most Hormuz Oil and Gas Ships Go Dark After US-Iran Peace Deal

Kpler data shows 89 of 112 vessels transiting the Strait of Hormuz (Aug 1–19, 2026) went dark — disabling AIS transponders or using neither corridor. Only two took the US-backed Omani route; 21 openly used Iran's. Argus Media reports traffic was unchanged after June's US-Iran peace deal, suggesting dark routing is now structural, not wartime.
