Hormuz shipping traffic dips as Red Sea route faces new threats
Two chokepoints tightening at once, not one.
Mark
So we're looking at four ships instead of sixteen. That's a real drop. But how much of that is actual avoidance versus ships just turning off their tracking?
Mimi
That's the honest question. Kpler's data is preliminary, and they flag it explicitly—some vessels kill their transponders in conflict zones. So the true number could be higher. But even accounting for that, the trend is real. Shippers are pulling back.
Luke
Right, but we don't know the magnitude of that adjustment. Is it ten percent of traffic going dark, or fifty percent? The source doesn't quantify it. We're working with a direction, not a precise number.
Mark
And the Red Sea route—that was supposed to be the safety valve, right? The alternative when Hormuz gets tight?
Mimi
Exactly. That's what makes Thursday's Houthi move so consequential. They seized the entire coastline, Saudi Arabia responded with airstrikes, and suddenly the backup route is under fire too. Shippers now have two constrained passages instead of one.
Luke
Though twenty-three ships still moved through Bab el-Mandeb on Thursday, versus an average of twenty-six. That's not a collapse. It's a dip.
Mark
But it's a dip happening at the same time as the Hormuz dip. That's the story—the timing.
Mimi
Precisely. A week ago, if Hormuz tightened, traders could reroute through the Red Sea. Now both are under pressure simultaneously. That's when you start seeing real supply concerns.
Luke
And we should note: the source says the Houthis are Iran-backed. That's important context for understanding why this matters geopolitically, but it's also one assertion in the reporting. It's accurate, but it's worth knowing that's the frame being used.
Mark
What happens next? Do we expect traffic to stabilize, or does this get worse?
Mimi
That's outside what the data can tell us. We're looking at one day's numbers and a ten-day average. The real test is whether shippers adjust their routes permanently or whether this is temporary volatility.
Der Puls
- Hormuz traffic collapsed to just four vessels on Thursday — a fraction of the sixteen-ship daily average — signaling that shippers are already pulling back from the world's most critical oil corridor.
- The same day, Houthi forces completed their takeover of Yemen's entire Red Sea coastline, triggering Saudi airstrikes and turning the backup route into a second front of danger.
- Traders who had quietly rerouted cargo through Bab el-Mandeb to avoid Hormuz now find that corridor threatened too, leaving Gulf oil and gas with a shrinking set of viable exits.
- Twenty-three vessels still moved through Bab el-Mandeb on Thursday — below its own ten-day average of twenty-six — suggesting pressure but not yet paralysis at the Red Sea chokepoint.
- The dual threat is forcing a tense calculation in shipping markets: whether current disruption levels hold, or whether simultaneous closures trigger a broader shock to global oil supply.
Two of the world's most consequential maritime passages — the Strait of Hormuz and the Bab el-Mandeb — are simultaneously under pressure, as regional conflict compresses the arteries through which a significant share of global energy flows. On Thursday, only four vessels transited Hormuz against a ten-day average of sixteen, while Houthi consolidation of Yemen's Red Sea coast and retaliatory Saudi airstrikes cast new uncertainty over the alternative route that shippers had quietly come to depend upon. The world has long understood that geography concentrates vulnerability; what this moment reveals is how quickly two chokepoints can become one shared crisis.
On Thursday, just four cargo vessels passed through the Strait of Hormuz — down from six the previous day and far below the typical daily count of around sixteen. The data, compiled by shiptracker Kpler, offered a stark illustration of how swiftly maritime traffic contracts when geopolitical risk tightens around the corridor that once carried roughly one-fifth of the world's oil and gas supply. The four ships — a mix of Panamax, Supramax, and Kamsarmax tankers — represent a real signal, even accounting for the fact that some vessels disable their transponders in conflict zones to avoid detection.
The same day Hormuz traffic fell, Iran-backed Houthi forces consolidated control over Yemen's entire Red Sea coastline, prompting the Saudi air force to launch retaliatory strikes. The escalation was significant not only in itself, but because the Red Sea route — accessed through the Bab el-Mandeb Strait at Yemen's southwestern tip — had become the primary alternative for shippers already wary of Hormuz. On Thursday, twenty-three vessels transited Bab el-Mandeb, modestly below its ten-day average of twenty-six, suggesting the route remains open but increasingly contested.
The deeper problem is structural. With Hormuz constrained by the Iran conflict and the Red Sea now threatened by Houthi control and active airstrikes, shippers face a narrowing map. Both chokepoints are under pressure simultaneously — and traders are watching closely to see whether disruptions stabilize at current levels or whether the dual threat forces a more dramatic reshaping of global energy flows.
On Thursday, only four cargo vessels moved through the Strait of Hormuz, a sharp drop from the six that had passed the day before and a significant retreat from the typical daily average of about sixteen ships. The data, compiled by shiptracker Kpler and released Friday morning, offered a snapshot of how quickly maritime traffic can contract when geopolitical risk tightens around the world's most critical oil and gas corridor.
Of those four vessels, three were entering the Gulf while one was leaving. The mix included two Panamax tankers, one Supramax, and one Kamsarmax—the standard workhorses of global commodity shipping. The numbers carry an important caveat: some ships disable their transponders while crossing conflict zones to avoid detection, which means the actual count could be higher than what tracking systems record. Still, the gap between four vessels and the ten-day average of sixteen is too wide to dismiss as a data artifact alone.
The Strait of Hormuz once carried roughly one-fifth of the world's oil and gas supply. That role has not changed. What has changed is the willingness of shippers to route their cargo through it. The same day that Hormuz traffic fell, the Iran-backed Houthis consolidated control over Yemen's entire Red Sea coastline, prompting the Saudi Arabian air force to launch retaliatory airstrikes. The escalation transformed what had been a regional tension into a direct threat to an alternative shipping corridor that traders had begun to rely on as Hormuz traffic tightened.
The Bab el-Mandeb Strait, which sits at the southwestern tip of Yemen and connects the Red Sea to the Gulf of Aden, saw twenty-three vessels pass through on Thursday—thirteen heading toward the Red Sea and ten toward the Gulf of Aden. That traffic included a Panamax and a Suezmax tanker, four Supramax vessels, and six Aframax tankers. The ten-day average for Bab el-Mandeb is around twenty-six ships daily, meaning Thursday's count of twenty-three represented a modest decline but not a collapse.
The real pressure lies in the geometry of the problem. With Hormuz constrained by the Iran conflict and now the Red Sea route threatened by Houthi control and Saudi airstrikes, shippers face a narrowing set of options for moving Gulf oil and gas to global markets. The Red Sea passage had emerged as the main alternative precisely because Hormuz traffic was already under strain. Now both chokepoints are simultaneously at risk. Traders are watching to see whether the disruptions stabilize at current levels or whether the dual threat forces a more dramatic reordering of shipping patterns—and with it, a potential shock to global oil supplies.
