Hormuz Vessel Traffic Slumps 66% to 53 Crossings as Renewed US-Iran Fighting Empties Oil Route
3 articles · Updated · CNBC · Jul 21
Summary
53 vessels transited the Strait of Hormuz in the week through July 20, down from 157 a week earlier, with tanker and gas carrier crossings falling to 30 from 90.
Renewed U.S. strikes on Iran, Tehran's blanket maritime ban and fresh attacks on commercial ships pushed operators to avoid the Gulf and reassess voyage risk.
Kpler data showed the drop began almost immediately after the blockade took effect: daily crossings fell from more than 20 before July 15 to 16 that day, then to single digits on July 16.
Commercial traffic still accounted for more than 70% of movements on July 17-19, but only about one-third was assessed as compliant with restrictions, while Iran-linked and sanctioned vessels dominated many transits.
Hormuz carries roughly a fifth of global oil consumption, and MST Marquee said flows have fallen to about 15% of pre-war levels, with oil potentially retesting $100 a barrel if fighting persists.

Strait of Hormuz Crisis 2026: Shipping Collapse, Energy Shock, and Global Supply Chain Disruption
Overview
In July 2026, a severe escalation of hostilities between the United States and Iran in the Strait of Hormuz triggered a profound crisis for global commercial shipping. The renewed conflict nullified a previous agreement, as Iran continued attacks on international shipping and the U.S. responded with targeted actions. This led to a dramatic collapse in shipping activity, especially for larger vessels, and forced many ships to go 'AIS-dark' to avoid detection. The International Maritime Organization expressed grave concern, highlighting the urgent need for de-escalation to restore safety and stability in this vital maritime corridor.
