For six months, the Strait of Hormuz — once the pulse point of a fifth of the world's energy trade — has been reduced to a shadow of its former self, as Iran's blockade has collapsed daily transits by 84 percent and left 6,000 sailors stranded in the Gulf with no clear passage home.

Strait of Hormuz paralyzed six months into war; thousands of sailors stranded
Approximately 6,000 sailors and crews remain stranded in the Gulf with 500 ships immobilized; at least 20 maritime workers killed in incidents over six months.
Two-thirds of ships now vanish into shadow, their transponders dark.

Why does the route matter so much? Can't ships just take a different way around?
Mimi
The strait is a chokepoint. Going around means adding weeks to a journey and enormous fuel costs. For oil and gas especially, the economics collapse. That's why one-fifth of global exports went through there before the war.
Mark
What's a "dark" transit? Why would a ship turn off its tracker?
Mimi
If you're a ship owner trying to move cargo through a war zone, you have to choose: follow Iran's approved route and risk being seen as complicit, or go dark and hope no one notices you. It's survival, not crime.
Mark
Six thousand sailors stuck—how long can that actually last?
Mimi
The IMO tried to evacuate them in June. One attack on an evacuation vessel and the whole operation stopped. These people aren't hostages in the traditional sense. They're just... forgotten. Waiting for politics to shift.
Mark
Is there any sign that will happen soon?
Mimi
Not really. The IMO says everything depends on de-escalation. But de-escalation requires both sides to step back, and right now neither seems willing. So the sailors stay, the ships sit, and the world finds other ways to get its oil.
Mark
What happens to the global economy if this lasts another six months?
Mimi
We're already seeing it. Prices rise, supply chains reroute, insurance costs spike. But it's a slow bleed, not a sudden collapse. The world adapts. The sailors, though—they're the ones who really pay.
O Pulso
- Iran's March closure of the strait sent daily cargo transits crashing from 95 ships to as few as 10, severing one of the world's most critical energy arteries almost overnight.
- A brief June ceasefire offered a fragile reprieve — traffic climbed back to 36 daily transits — but when hostilities resumed on July 8, the recovery collapsed just as quickly as it had come.
- Two competing and dangerous routes have replaced the single IMO-standardized corridor: an Iranian-approved northern passage and a southern lane where Tehran has warned of a 1,400-square-kilometer minefield.
- Two-thirds of all remaining transits are now 'dark' — ships disabling transponders and disappearing from tracking systems — a near-total inversion from the pre-war norm of less than one percent invisible traffic.
- An IMO evacuation effort meant to free more than 11,000 seafarers was suspended after one of its own vessels was attacked, leaving 6,000 sailors and 500 ships immobilized with at least 20 maritime workers already dead.
- Officials say a secure corridor remains under discussion, but any breakthrough is hostage to regional de-escalation — a condition that, six months in, shows no sign of arriving soon.
For six months, the Strait of Hormuz — once the pulse point of a fifth of the world's energy trade — has been reduced to a shadow of its former self, as Iran's blockade has collapsed daily transits by 84 percent and left 6,000 sailors stranded in the Gulf with no clear passage home. What was once a corridor of routine commerce has fractured into competing routes: one sanctioned by Tehran along its own coastline, another shadowed by mine warnings along the Omani side, and a vast middle ground where ships vanish from tracking entirely. The human story behind the tonnage figures is one of ordinary workers — engineers, cooks, deckhands — caught motionless between warring powers they did not choose. Resolution, maritime officials acknowledge, belongs not to the sea but to the land, and to whatever political will might yet find its way toward de-escalation.
Six months after Iran closed the Strait of Hormuz in response to joint US-Israeli strikes, the waterway that once carried roughly one-fifth of the world's oil and liquefied natural gas has been reduced to a trickle. Before the blockade took full effect on March 1, an average of 95 cargo ships transited the passage daily. That figure fell to 10 at the height of the closure, recovered briefly to 36 during a June ceasefire agreement, then collapsed again to just 15 per day after hostilities resumed on July 8 — an 84 percent decline from pre-war levels.
The physical geography of the strait has fractured along with the traffic. Where ships once followed a single IMO-standardized central corridor, two competing routes now exist: a northern passage hugging the Iranian coast, the only one Tehran officially permits, and a southern lane along the Omani side where Iranian forces have warned of a 1,400-square-kilometer danger zone seeded with mines. The uncertainty has driven a dramatic shift in how vessels move — or disappear. Before the war, fewer than one percent of transits were 'dark,' meaning ships with disabled transponders or jammed signals. Since July 8, that figure has risen to two-thirds of all transits, as operators choose invisibility over the risk of Iranian interdiction or mines.
Behind the statistics is a human crisis that has drawn far less attention than the commodity markets. The IMO estimates that approximately 6,000 sailors — engineers, deckhands, officers, cooks — remain stranded aboard some 500 immobilized ships in the Gulf, caught between two warring powers with no agency over their own fate. An evacuation initiative launched in June to extract more than 11,000 seafarers from the region was suspended after an attack on one of the evacuation vessels. At least 20 maritime workers have been killed over the six-month period.
The IMO says it continues to pursue a secure maritime corridor, but officials are candid: any solution depends entirely on whether the broader conflict can be brought toward de-escalation. For now, the strait remains closed to meaningful commerce, its routes fractured and mined, and thousands of ordinary workers wait for a war they did not start to finally end.
Six months into the war, the Strait of Hormuz has become a graveyard of commerce. The waterway that once carried roughly one-fifth of the world's oil and liquefied natural gas now sees only a trickle of traffic—a collapse so severe that it has left thousands of sailors marooned in the Gulf with no clear path home.
Before Iran closed the strait in early March, responding to joint US-Israeli strikes the month before, an average of 95 cargo ships transited the passage daily. By the time the blockade took full effect on March 1, that number had plummeted to 10 transits per day. The numbers tell the story of a global supply chain in shock. For a brief window in June, after the United States and Iran signed an agreement, traffic rebounded to 36 ships daily. But when hostilities resumed on July 8, the gains evaporated. Between that date and late August, the average settled at just 15 transits per day—an 84 percent collapse from pre-war levels.
The physical reality on the water has become even more fractured. Before the conflict, ships followed a single standardized route through the center of the strait, a corridor established by the International Maritime Organization. Now there are two competing passages: one hugging the Iranian coast, the only route Tehran officially permits, and another running along the Omani side, where Iranian forces have warned of a 1,400-square-kilometer danger zone seeded with mines. During the brief ceasefire in June and early July, roughly nine ships per day used the Iranian route while eight took the southern passage. The rest vanished into shadow.
Since July 8, two-thirds of all transits have become what maritime trackers call "dark"—vessels whose exact location and route cannot be confirmed because their transponders are disabled, their signals jammed, or satellite imagery is unavailable. Before the war, such invisible transits accounted for less than one percent of traffic. The shift suggests a maritime world operating in the dark, with ship operators choosing anonymity over certainty as they navigate between Iranian demands and the threat of mines.
The human cost has been largely invisible to the world watching the headlines. The International Maritime Organization reports that approximately 6,000 sailors and 500 ships have been trapped in the Gulf since the conflict began. These are working people—engineers, deckhands, cooks, officers—caught between two warring powers with no control over their fate. The IMO launched an evacuation initiative in June to extract more than 11,000 seafarers from the region, but the effort ground to a halt after an attack on one of the evacuation vessels. At least 20 sailors and dockworkers have been killed in incidents or attacks over the six-month period, according to the organization's count.
The IMO says it continues discussions aimed at establishing a secure maritime corridor, but officials acknowledge that any breakthrough depends entirely on whether the region can de-escalate. For now, the Strait of Hormuz remains a place where commerce has stopped, routes have fractured into competing passages, and thousands of ordinary workers wait for a conflict they did not start to end.
