Hormuz transits fall to single digits as tanker attacks continue
Vessel transits through the Strait of Hormuz dropped to seven in a day, even as Washington says it has loosened Iran’s grip on the waterway.
Vessel transits at the Strait of Hormuz fell to seven on Thursday from 11 the previous day, according to preliminary ship-tracking data published on Friday1. UK Maritime Trade Operations reported that two more vessels were attacked on the Omani side of the strait, the latest in a series of such incidents2.
Iran’s Revolutionary Guard said its navy struck a US-operated surface drone at the entrance of the strait7. US Central Command said 96 vessels have been redirected under the American blockade on Iran5.
Brent crude traded at $108 a barrel as the attacks continued2. Energy Secretary Chris Wright said in an interview with Bloomberg TV that nearly 11 million barrels of oil pass through the strait daily6.

Why it matters to investors
Single-digit daily transits against a normal flow of roughly 11 million barrels a day is the clearest available measure of how much energy is not reaching the market1,6. Every incremental attack on the Omani route compounds it, because the alternative lane is the one being targeted2.
The blockade cuts both ways. The Associated Press reported that the United States has succeeded in loosening Iran’s grip over the strait while virtually shutting down Iran’s own exports4. That is a supply reduction on both sides of the ledger, which is why the oil price has not responded to the American progress with relief2.
The redirection of 96 vessels is the scale of the logistical disruption5. President Trump framed the campaign in terms of ending Iran’s regional dominance, saying the country had been the bully of the Middle East for 51 years and is not the bully any more5.
What to watch
The nearest catalyst is diplomatic. Iran and Gulf states are to meet in a push for a Hormuz deal, though Iran insists on conditions even if an agreement is finalised3. A negotiated reopening is the fastest route to lower transit risk, and the only one on the table.
The second is the transit count itself, which has become a daily indicator worth more than sentiment surveys: seven crossings against 11 the day before shows how quickly the figure can move1.
The third is escalation at sea. The strike on the American surface drone7 and the continuing attacks on tankers on the Omani route2 suggest that the corridor is contested at a level that neither the blockade nor the reported American progress has settled4.
