The contradiction was stark enough to unsettle traders and shipowners
At the intersection of diplomacy and commerce, the Strait of Hormuz — that narrow passage through which a fifth of the world's oil must travel — became on Friday a mirror of the contradictions governing the US-Iran standoff. Iran's foreign minister declared the strait open; Iran's parliament speaker threatened to close it again; the United States maintained its naval blockade regardless. In the space between those competing declarations, oil markets lurched, shipowners hesitated, and the ancient question reasserted itself: when powerful actors speak with different voices, which voice governs the sea?
- Iran's foreign minister and parliament speaker issued flatly contradictory statements within hours of each other on Friday, leaving traders and tanker owners with no reliable signal to act on.
- The US naval blockade on Iranian ports remained fully in force even as ceasefire announcements circulated, with nineteen vessels already turned back and none successfully passing through.
- Brent crude futures fell more than 10 percent on the initial opening announcement, only for markets to pull back as the afternoon's contradictions erased confidence in the news.
- Shipowners are holding back: the ceasefire expires April 22, passage terms are vague, Iran may impose transit tolls, and interception risk persists in the Gulf of Oman even beyond the strait itself.
- An estimated 120 loaded tankers are trapped and waiting to depart, suggesting the announcement may have been designed to relieve that backlog rather than reopen a genuine trade corridor.
On Friday morning, Iran's foreign minister announced the Strait of Hormuz would open to commercial shipping for the duration of a ceasefire between the US and Iran. President Trump quickly confirmed the strait was "COMPLETELY OPEN." Oil markets responded at once — Brent crude futures fell more than 10 percent. By afternoon, however, the picture had fractured: Mohammad Bhager Ghalibaf, speaker of Iran's parliament, warned that the strait would not remain open if the United States continued its blockade of Iranian ports. The contradiction was sharp enough to unsettle anyone who had begun planning a transit.
The blockade was the sticking point. The US military had established a naval cordon around Iranian ports earlier in the week, and Trump made clear it would stay until what he called "OUR TRANSACTION WITH IRAN IS 100% COMPLETE." By Friday, nineteen ships had been turned back; none had evaded the cordon. The geography mattered too: the Strait of Hormuz and the mouth of the Persian Gulf are not the same waterway. A vessel could clear the strait and still face interception further downstream in the Gulf of Oman, where the blockade was concentrated.
Shipowners were not rushing to test the new conditions. The ceasefire was set to expire on April 22, passage terms were vague, and Iran's reference to a "coordinated route as already announced" raised the possibility of continued transit tolls. The International Maritime Organisation was reviewing Iran's announcement for compliance with freedom of navigation standards. A handful of vessels had crossed — the Pakistani-flagged tanker Shalamar among them — but the overall posture was one of caution.
The announcement may have been aimed less at opening a new trade corridor than at releasing the roughly 120 loaded tankers already trapped and waiting to depart, a figure cited by the International Energy Agency's executive director. Easing that backlog could calm markets without committing to anything durable. The ceasefire remained fragile, the blockade remained in force, and the terms of passage remained opaque. For shipowners who depend on clear rules, the strait had become a place of ambiguity — and the real question was not whether it was open, but whether anyone would actually use it.
On Friday morning, Iran's foreign minister announced that the Strait of Hormuz would open to commercial shipping for the duration of a ceasefire between the US and Iran, following a halt to fighting in Lebanon. Within hours, President Trump confirmed the strait was "COMPLETELY OPEN" and ready for passage. Oil markets reacted immediately—Brent crude futures fell more than 10 percent on the news. But by afternoon, the picture had fractured. Mohammad Bhager Ghalibaf, speaker of Iran's parliament, issued a statement saying the strait would not remain open if the United States continued its blockade of Iranian ports. The contradiction was stark enough to unsettle traders and shipowners who had begun calculating the implications of renewed transit.
The blockade itself remained the sticking point. The US military had begun enforcing a naval cordon against vessels entering or leaving Iranian ports earlier in the week, and Trump made clear it would stay in place until what he called "OUR TRANSACTION WITH IRAN IS 100% COMPLETE." Even as the foreign minister spoke of opening the strait, US Central Command was directing merchant vessels to turn around and return to Iranian ports. By Friday, nineteen ships had complied with those orders; none had successfully evaded the blockade. The distinction mattered enormously: the Strait of Hormuz and the mouth of the Persian Gulf are not the same waterway. A vessel could transit the strait itself and still face interception further downstream in the Gulf of Oman, where the blockade was concentrated.
Shipowners were not rushing to test the new conditions. Market participants told Argus that the limited timeframe of the ceasefire—set to expire on April 22—combined with vague terms of passage, made immediate resumption of traffic unlikely. Iran had said vessels would use a "coordinated route as already announced," language that suggested the channel between the islands of Qeshm and Larak. This phrasing also raised the possibility that Iran would continue collecting transit tolls. One trader noted that owners would need to "coordinate with Iran and adhere to their rules" unless conditions became clearer. The International Maritime Organisation was already reviewing Iran's announcement for compliance with freedom of navigation standards, adding another layer of uncertainty. A vessel or two had crossed the strait in the past day—the Pakistani-flagged tanker Shalamar among them—but the overall picture was one of caution.
The announcement itself may have been aimed less at encouraging new business than at allowing vessels already trapped in the Gulf to escape. An estimated 120 loaded tankers were waiting to depart, according to the International Energy Agency's executive director. Easing that backlog would help calm markets without necessarily opening a new corridor for trade. The ceasefire was fragile, the blockade remained in force, and the terms of passage were opaque. Iran's foreign minister and parliament speaker had sent contradictory signals within hours of each other. For shipowners accustomed to clear rules and stable conditions, the Strait of Hormuz—through which roughly one-fifth of global oil flows—had become a place of ambiguity. The question was not whether the strait was open, but whether anyone would actually use it.

The strait will not remain open while the US continues to blockade Iranian ports.— Iranian Parliamentary Speaker Mohammad Bhager Ghalibaf
La Conversación del Hearth Otra perspectiva de la historia
Why would Iran's parliament speaker contradict the foreign minister on the same day?
Because the two statements serve different audiences and purposes. The foreign minister is signaling to the world that Iran is cooperating with the ceasefire. The parliament speaker is reminding Iran's domestic base that the country won't simply capitulate—that the blockade is unacceptable and has consequences.
But doesn't that undermine Iran's credibility?
It does, which is the real problem. Shipowners need to know what the rules actually are. Conflicting signals from the top mean no one can plan.
The US blockade is still in place even though the strait is supposedly open. How does that work?
The blockade targets Iranian ports specifically—the entrances and exits to the Gulf. The strait itself is a transit corridor. A ship can cross the strait and still be intercepted when it tries to leave the region entirely. It's a distinction that matters legally but feels meaningless to a captain.
So the 120 tankers waiting to leave—they're stuck either way?
Not entirely. If the ceasefire holds and conditions clarify, they could exit through the strait and potentially avoid the blockade zone. But that requires trust in an arrangement that just showed signs of fracturing.
What would make shipowners actually use the strait?
Clear rules, a longer timeframe than two weeks, and assurance that passage won't be interrupted downstream. Right now they have none of those things. It's safer to wait.
