Hormuz transits plummet to 9 vessels as regional tensions persist
Nine vessels where 125 once flowed daily
Mark
So nine ships in a day through Hormuz—is that actually alarming, or is it just a normal fluctuation?
Mimi
It's alarming. Before the war, the strait moved about 125 large vessels daily. Nine is roughly one-fifteenth of that. We're talking about a ninety-three percent drop.
Luke
But wait—the data is preliminary, and some ships are running dark, transponders off. So the actual number could be higher. We don't know how many are hiding.
Mimi
True. The ten-day average is eighteen, which suggests Thursday was particularly bad. But even eighteen is nowhere near normal.
Mark
Why would companies turn off transponders? What does that accomplish?
Mimi
It makes the ship harder to track, harder to target. In a conflict zone, visibility can be a liability. It's a sign of how unsafe captains feel.
Luke
Though we should note—the source doesn't explain why Thursday dropped so sharply from Wednesday's fourteen. Was there a specific incident? We don't know.
Mark
And this matters because Hormuz handles twenty percent of the world's oil and gas?
Mimi
Exactly. One-fifth of global crude and LNG supply flows through that strait. When traffic collapses, energy prices rise, shipping costs spike, and supply chains feel it everywhere.
Luke
The Bab el-Mandeb numbers stayed flat at twenty-six, which is interesting—suggests the disruption is concentrated at Hormuz, not spreading to other routes yet.
Mark
Yet being the operative word.
Mimi
Right. This is a snapshot from one day. The question is whether this becomes the new normal.
The Pulse
- Transit volumes through the Strait of Hormuz have collapsed to less than one-tenth of pre-war levels, with just nine vessels recorded on Thursday — down from fourteen the day before.
- Eight of those nine ships were exiting, not entering, suggesting a one-way drain rather than a functioning two-way trade corridor.
- Some vessels are now switching off their tracking transponders entirely, meaning the official count almost certainly understates how thin — or how covert — actual traffic has become.
- The ten-day rolling average of eighteen daily transits remains catastrophically below the historical norm of 125, signaling this is not a temporary disruption but a sustained structural shift.
- At the nearby Bab el-Mandeb strait, traffic held relatively steady at twenty-six vessels Thursday, highlighting how isolated — and how severe — the Hormuz collapse truly is.
- Energy markets and industries dependent on steady crude and LNG flows face mounting pressure as rerouting around Africa adds enormous cost and delay to every diverted shipment.
Through the narrow passage of the Strait of Hormuz — once a corridor carrying a fifth of the world's oil and gas — only nine vessels moved on Thursday, a ghost of the 125 that once transited daily before conflict reshaped the region in late February. The numbers, drawn from ship-tracking data, tell a quiet but consequential story: global energy arteries are constricting, and the world's markets feel the pressure with every vessel that turns away. What was once routine passage has become a calculation of risk, rerouting, and silence — some ships now moving through with their transponders dark, invisible to the very systems meant to count them.
The Strait of Hormuz recorded just nine vessel transits on Thursday — eight departing, one arriving — a figure compiled from preliminary ship-tracking data and released the following day. Among the outbound traffic were smaller tankers, one very large crude carrier loaded with oil, and one ballast gas carrier. A single dry bulk carrier made the inbound crossing.
Before the Iran war began on February 28, the strait was one of the busiest and most consequential waterways on earth, handling roughly 125 large commercial vessels daily and channeling approximately one-fifth of the world's crude oil and liquefied natural gas supply. Current traffic represents less than one-tenth of that baseline, and the ten-day rolling average sits at just eighteen transits per day.
The thinning numbers do not capture the full picture. An unknown number of vessels are now transiting with their transponders disabled, disappearing from official counts entirely — a sign that risk calculations, not just rerouting, are reshaping how ships navigate the region.
At the Bab el-Mandeb strait, another key chokepoint for Middle Eastern energy exports, conditions appeared more stable. Twenty-six vessels transited Thursday, including a laden very large crude carrier carrying Iraqi Basrah crude toward Egypt, its tracking system active and visible.
The contrast between the two straits underscores how concentrated the disruption has become around Hormuz. Ships that once passed through without hesitation are now avoiding it altogether, bearing the enormous cost of rerouting around Africa, or moving through in deliberate silence — each choice a measure of how profoundly the geopolitical landscape has shifted since late February.
The Strait of Hormuz, one of the world's most critical shipping channels, saw only nine vessels pass through on Thursday, down sharply from fourteen the day before. Of those nine, eight were leaving the waterway and one was entering—a dry bulk carrier heading inbound. The outbound traffic consisted mostly of smaller tankers, along with one very large crude carrier loaded with oil and one ballast very large gas carrier.
These numbers, compiled from preliminary shiptracking data and released Friday, represent a fraction of what moved through the strait before the Iran war began on February 28. In the years before that conflict, the Strait of Hormuz typically accommodated roughly 125 large commercial vessels each day—tankers, gas carriers, bulk carriers, container ships—a steady stream that represented about one-fifth of the world's daily crude oil and liquefied natural gas supply. The current traffic is less than one-tenth of that baseline.
The decline reflects the persistent regional tensions that have made passage through the strait riskier and more uncertain for shipping companies. Some vessels are now transiting with their transponders switched off, which means they do not appear in the official counts at all. The ten-day rolling average of transits stands at eighteen vessels per day, still dramatically below historical norms.
At the nearby Bab el-Mandeb strait, another critical chokepoint for Middle Eastern energy exports, traffic remained relatively stable. On Thursday, twenty-six vessels moved through—twelve entering and fourteen exiting—showing little change from Wednesday's numbers. Among those entries was a laden very large crude carrier carrying Iraqi Basrah crude bound for Egypt, its tracking system active and visible to monitoring services.
The collapse in Hormuz transits underscores how thoroughly the conflict has disrupted one of global commerce's most essential routes. Ships that would normally flow through without hesitation are now either avoiding the passage entirely, rerouting around Africa at enormous cost and delay, or moving through with identification systems disabled. For energy markets and the industries dependent on steady crude and gas supplies, the thinning traffic is a visible measure of how much the geopolitical landscape has shifted since late February.
