The world heard the command: "Start your engines." But the captains heard something else: "Survive first." Sometimes, the global economy depends not on stock market indices, central bank meetings, or the loud speeches of politicians, but on a narrow strip of water where a captain's mistake, a diplomat's imprecise wording, or a single forgotten naval mine can cost billions of dollars. The Strait of Hormuz has once again become exactly that kind of place.
US President Trump announced what oil traders, shipowners, insurers, tanker captains, Asian refiners, European importers, and millions of consumers around the world had been waiting for since early March. After months of blockades, threats, military maneuvers, conflicting statements, and nervous anticipation, he announced that a deal had been reached to open the Strait of Hormuz and lift the US naval blockade.
The phrase sounded dramatic, in Trump's signature style: "Ships of peace, start your engines." In another message, he added: "Let the oil flow!" For political theater, it was the perfect scene. For the shipping industry, it was the beginning of a completely different story.
The problem is that a ship's engine is the easiest thing to start. The engines on most vessels were not dead anyway. The real question is not whether they can move. The question is different: Who will be the first to risk entering a water corridor that just yesterday was called a war zone? Who guarantees that the mines have actually been cleared? Who will determine the departure order for the roughly 600 vessels stranded in the Persian Gulf? Who will be responsible if one tanker hits a mine, another comes under fire, a third violates confusing new rules, and a fourth collides on an overcrowded route?
Trump delivered a political formula. The maritime market heard legal fog.
A Deal Exists, but an Open Strait Does Not Yet
On June 15, US President Trump, Vice President JD Vance, and Iranian Parliament Speaker Mohammad Bagher Ghalibaf signed a memorandum of understanding digitally. The formal signing ceremony is scheduled for June 19. It is precisely this time gap—between the announcement and the legal formalization—that has become the main source of risk.
On paper, it looks simple: The US and Iran agreed, Hormuz must open, the blockade must be lifted, and ships must move. However, shipping operates differently than political social media posts. The maritime business lives by insurance terms, sanctions regimes, routing schemes, naval instructions, war risk levels, and commercial obligations.
For a captain, shipowner, and insurer, it is not enough to hear that the strait is "fully open." They need to understand who controls the route, which waters are safe, which payments are legal, who is responsible for mine clearance, whether all parties to the conflict recognize the deal, and what happens if one side claims a violation in three days.
Trump claimed that vessels have already begun moving along the southern route, which passes through Omani territorial waters. He called this route safe, secure, and clear. But vessel tracking data showed a much more cautious picture: Not a mass unblocking, but only the limited movement of a few oil tankers.
This is a crucial detail. In global shipping, the first vessels to move after a crisis do not prove a route is safe. They merely show that someone is willing to accept heightened risk for commercial gain. The rest watch. And that is exactly what is happening in Hormuz right now.
600 Ships Trapped: Who Leaves First and Who Remains Hostage to a 60-Day Peace
One of the most alarming aspects of the current crisis is the number of vessels stranded in the Persian Gulf. We are talking about approximately 600 ships. These are not just oil tankers. They include LNG carriers, container ships, bulk carriers, product tankers, chemical tankers, supply vessels, and cargo ships carrying fertilizers and other goods.
Their problem cannot be reduced to a simple formula of "the strait opened, everyone left." The strait is not an empty highway. It is one of the most sensitive maritime corridors on the planet, where the standard flow of traffic was disrupted by war, and the usual traffic separation scheme has effectively ceased to function.
Before the war, traffic in the strait was regulated by a traffic separation scheme linked to Iran and Oman. After the conflict began, this system was warped. Vessels that still managed to pass used two alternative routes: a northern one along the coast of Iran and a southern one along the coast of Oman. As a result, a water corridor that should operate like an orderly two-lane road turned into an improvised four-lane system with differing political, military, and sanctions risks.
This is where the real struggle begins—not military, but commercial. The 60-day truce creates a window of opportunity, but it simultaneously creates a race. Everyone understands that if the truce does not evolve into a lasting peace agreement, some ships might not make it out in time. Then they will find themselves hostage to the crisis once again—possibly for an even longer period.
For owners of oil, gas, and product tankers, an early departure can mean enormous profits. Oil and petroleum products delivered first after a crisis are sold amid heightened market anxiety. Gas arriving at the right moment can fill critical shortages. Fertilizers are valuable before the agricultural season begins but lose much of their commercial value after that critical window closes.
Therefore, in the coming days, Hormuz will look less like a peaceful corridor and more like a departure lounge before an evacuation, where every passenger believes their ticket should be first.
The Southern Route: A "Safe Highway" That Can Only Handle a Tenth of Regular Traffic
The most likely favorite will be the southern route through Omani waters. It has long been perceived as a path under the protection of the US and its partners. For Western shipowners, this is a psychologically and legally more acceptable option.
But there is a hard limit: This route cannot quickly absorb the entire flow. According to an assessment by Svein Ringbakken, Managing Director of the naval war insurer DNK, the southern route can handle only about 10% of the normal traffic volume through the strait. This means that any attempt at a mass exodus from the Persian Gulf will inevitably lead to queues, delays, competition for slots, and an increased risk of navigational incidents.
Ten percent is not a minor technical detail. It is a strategic bottleneck. If the normal Hormuz was an artery, the southern route turns it into a capillary. You can pump the blood of the economy through it, but you cannot instantly restore full circulation.
Under the conditions of a 60-day truce, this is particularly dangerous. If the corridor is physically capable of handling only a fraction of normal traffic while hundreds of ships are eager to leave as soon as possible, it creates more than just a logistical traffic jam. It creates a market for access to safety. Whoever gets a slot early wins. Whoever is late risks being stuck until the next phase of the crisis.
This is why politicians' statements about a "fully open strait" sound too simplistic to the shipping industry. The strait will not become fully open just because US President Trump writes it. It will become open when insurers lower war premiums, routes are declared safe, mines are localized, sanctions issues are resolved, and traffic can flow not symbolically, but en masse.
Iran's Northern Path: A Corridor for Friends and a Trap for Western Companies
The alternative to the southern route is the northern path along the Iranian coast. It is particularly important for vessels connected to countries friendly to Iran, as well as for ships carrying Iranian oil. This route is now effectively administered by a new Iranian entity—the Persian Gulf Strait Authority.
For Tehran, this is not just a technical body. It is an instrument of political control over an area that Iran considers its natural sphere of influence. Creating such a structure allows Iran to say: The strait is open not because the US allowed it, but because Iran is organizing the passage.
This is where one of the main contradictions of the entire deal arises. The US says: Everyone is free to leave. Iran says: We determine the procedure. For shipowners, this is not a diplomatic nuance, but a question of legal survival.
Western companies cannot simply go ahead and pay the Iranian authorities for passage if such payments fall under sanctions restrictions. Sanctions do not vanish just because the parties signed a memorandum. Banks, insurers, charterers, and shipowners will demand clear explanations: Exactly which payments are permitted, who accepts them, through which channels, with what guarantees, and do they create a risk of secondary sanctions?
The Iranian news agency Fars reported that under the terms of the truce, Tehran will be able to collect fees from vessels passing through Iranian waters. Iranian Foreign Ministry spokesperson Esmaeil Baghaei stated that fees would be charged for services rendered. At first glance, this looks like a standard service charge. In reality, it could become a legal mine of no less potency than the physical mines in the strait.
Because at the same time, US President Trump told The New York Times that Hormuz would be "forever toll-free." It turns out Washington promises free passage, Tehran talks about service fees, and shipowners must decide whom to trust with their money, their ships, and the lives of their crews.
Mines in the Water and Mines in the Wording: The Captains' Main Fear
The most dangerous question is not diplomatic, but physical: mines.
It remains unclear whether Iran knows the exact location of all the mines laid in the strait and whether it is capable of clearing them quickly. In modern naval conflicts, the mine threat possesses a unique psychological power. A missile can be tracked, a warship can be seen, a drone can be shot down. A mine remains silent. It does not negotiate. It waits.
For a commercial vessel, even the probability of an explosion changes the entire economics of a voyage. War insurance premiums spike. Charterers demand discounts or guarantees. Banks get nervous. Crews refuse to enter an area of uncertain risk. Captains demand written instructions. Shipowners look for legal cover. Ports of destination adjust their schedules.
Svein Ringbakken rightly noted that if Iran does not disclose where the mines are located, and if a cleared route is not clearly marked, less cautious operators will go first. The rest will join only when they see that the path has proven safe in practice.
This means that the first transits through Hormuz after the deal's announcement will not be trade operations so much as reality tests. Each successfully passing tanker will reduce fear. Every incident—even a minor one—is capable of sending the market back into a state of panic.
Why a Single Passing Tanker Does Not Mean the Global Economy Is Saved
Politics loves symbols. One tanker passed, so the strait is open. A few ships moved, so the market will calm down. Footage of movement on the water can be shown as proof of success.
But global trade does not operate on symbols. It operates on volume, regularity, and predictability.
Even if a few ships have already safely passed through Hormuz, this does not guarantee the same for the rest. The first vessels may have passed along a restricted route, under escort, in favorable conditions, and after individual clearance. Mass movement is a completely different level of risk. When dozens of ships are moving in both directions, when some choose the southern route and others the northern one, when some pay Iran and others cannot pay, when some are tied to Western insurers and others operate in gray schemes, the strait becomes not an open corridor, but a complex system of conflicting regimes.
Another factor is equally important: The normalization of Hormuz is not just about ships leaving the Persian Gulf. It is also about resuming inbound traffic. For oil, gas, and industrial logistics to return to normal, shipowners must once again believe that sending vessels into the Persian Gulf is safe. Until that trust is established, the region will operate in a state of incomplete recovery.
This is critical for the Persian Gulf nations. Hydrocarbon exports are the foundation of their economic model. But it is no less critical for consumers in Asia and Europe. Any prolonged uncertainty around Hormuz is reflected in oil prices, shipping costs, insurance, delivery times, inflationary expectations, and energy security.
60 Days of Peace: The Truce as a Countdown, Not a Guarantee
The ceasefire agreement is structured for 60 days. In diplomatic terms, this is a window for further negotiations. In the language of shipping, it is a ticking countdown timer.
Every single day of this period will carry a commercial price tag. If a vessel departs on the tenth day, it operates within one window of opportunity. If it waits until the fiftieth day, the reality is entirely different. Should the truce collapse on the thirtieth day, a portion of the fleet will find itself trapped once again. If extended, the market will stabilize incrementally. If a permanent peace treaty emerges, Hormuz will begin its return to normalcy. At this moment, however, none of these scenarios can be taken for granted.
Particularly alarming is how differently the terms of the deal are being interpreted within the very first days of its announcement. US President Trump declared upon his arrival in France for the G7 summit that the strait would be completely open on Friday. Conversely, the Iranian news agency Mehr reported a different reality: according to the 14-point plan agreed upon by the US and Iran, Hormuz will open not on June 19, but within 30 days, under the terms of Iranian management of the process.
The discrepancy between "on Friday" and "within 30 days" is monumental. To a politician, it is a debate over interpretation. To a shipowner, it is the difference between an immediate voyage and a month of idle waiting. For the oil market, it represents the choice between a swift drop in anxiety and the prolonged retention of a risk premium. For a captain, it is the difference between an order to sail and an order to hold position.
The Lebanon Fuse: Why the Fate of Hormuz May Be Decided Elsewhere
There is another geopolitical risk rendering this deal exceptionally fragile: Lebanon.
The US, Iran, and Pakistan have stated that the peace agreement encompasses a cessation of violence in Lebanon. Israel, for its part, has declared that its forces will remain in place. On June 16, Iranian Foreign Minister Abbas Araghchi warned that Tehran would treat any Israeli strike on Lebanon and any continued occupation as a direct violation of the memorandum of understanding.
This implies that the fate of the vessels in Hormuz depends not only on the conduct of the US and Iran in the Persian Gulf, but also on events unfolding on an entirely different front. A single strike in Lebanon, one tactical operation, one political escalation—and the legal framework of the truce could instantly shatter.
For the shipping industry, this architecture is a nightmare. Commercial vessels must make critical transit decisions through Hormuz, yet their risk profile is bound to a regional chain where Lebanon, Israel, Iran, the US, and their partners are locked into a single system of mutual threats. A tanker captain does not control this system. The insurer does not control it. The shipowner does not control it. Yet all of them must foot the bill for its volatility.
This explains why many vessels are hesitant. They are not merely waiting for signatures on June 19. They are waiting for the first signs that the deal can withstand the first external shock.
The Sanctions Paradox: War Leading to the Legalization of Payments to Iran
One of the most ironic details of this entire saga is the issue of service fees. If Iran successfully secures the right to levy charges on vessels transiting its waters, it will create a paradoxical outcome to the conflict. A confrontation that began as a tool to apply maximum pressure on Iran may conclude with Western corporations actively seeking legal authorization to transfer funds to Iranian entities.
This is far more than a technical hurdle. It is a matter of profound political symbolism. For years, the US built a comprehensive sanctions architecture against Iran to restrict its access to global financial flows. Now, the normalization of Hormuz may demand carving out exceptions from that very architecture. If such waivers are granted, Tehran gains not just financial revenue, but formal recognition of its role as the administrator of a pivotal maritime artery.
For Iran, this represents a significant diplomatic victory. Tehran will be positioned to claim that it did not capitulate, but instead forced the recognition of its regulatory control. For the US, this will be far more complicated to explain—especially if US President Trump continues to maintain that transit must be free, while Iranian officials continue to dictate terms for service fees.
For business, it becomes a question of accounting, compliance, and criminal risk. A compliance error in a payment transaction can prove just as costly as a physical vessel delay. Consequently, the legal departments of major shipping lines will move with extreme caution. They do not require rhetoric; they require written licenses, clear exemptions, functioning banking channels, and absolute insurance confirmations.
Who Risks First: A Market of Heroes or a Market of the Desperate
Following any major crisis, a specific class of operators emerges willing to make the first move. At times, these are powerful corporations with robust political connections and access to military intelligence. In other instances, they are less cautious players willing to embrace high risks in pursuit of outsized profits. Sometimes, they are shipowners who simply have no alternative: the cargo is spoiling, the contract is expiring, the charterer is applying pressure, and the financing bank is demanding the fulfillment of obligations.
These entities will serve as the initial scouts of Hormuz. Their transits will be meticulously tracked by everyone else: insurers, commodity traders, military analysts, oil majors, ports, and exchanges. Each completed voyage will act as a market signal. If the first 10–20 vessels pass without incident, the market will begin to breathe a sigh of relief. If a detention occurs, a mine detonates, a warning shot is fired, a payment dispute arises, or a new threat is leveled, confidence will instantly disintegrate.
Such is the nature of maritime psychology. Safety in this domain is demonstrated not by declarations, but by repetition. A single success is an anomaly. Ten successes establish a trend. One hundred successful transits represent a return to normalcy.
Until that threshold is reached, Hormuz remains not an open door, but a door with an unverified lock.
Oil, Gas, and Fertilizers: Why Commercial Pressure Will Outweigh Diplomatic Caution
The economics governing an exit from the Persian Gulf will be unforgiving. The oil and gas currently stranded in the region represent too much capital for shipowners to wait indefinitely for flawless regulatory clarity. Petroleum products are urgently required by global markets. Fertilizers must arrive before agricultural cycles commence. Containerized cargo rapidly depreciates as supply chains remain broken. Delivery schedules are no longer a minor logistical detail; they are the primary determinant of profit and loss.
As a result, commercial pressure will compel vessels forward much faster than diplomats can clarify their legal language. This creates the dangerous disconnect of the present moment. The political deal is not yet fully formalized. Military risks have not been neutralized. The sanctions regime has not been adapted. The minefields have not been mapped. Yet, the market is already demanding movement.
It is precisely within these structural gaps that disasters frequently materialize. Not because the participants are inherently reckless, but because each actor behaves rationally under conditions of imperfect information. The shipowner calculates the escalating losses of delay. The insurer increases the premium. The charterer demands performance under the contract. The captain requests a verified safe route. Sovereign states clash over jurisdiction. Ultimately, the system absorbs a collective risk that no individual participant would ever choose to accept independently.
Trump Speaks the Language of Victory; Hormuz Responds in the Language of Risk
US President Trump is determined to present the agreement as a rapid, decisive triumph. Within his political logic, the strategy is obvious: he is announcing the end of a crisis, the opening of the strait, the lifting of a blockade, and the return of oil to global markets. This creates the narrative of a leader who single-handedly unblocks a vital global artery with a single decision.
However, Hormuz does not yield to political rhetoric. It is a space where every word is weighed against deadweight tonnage, insurance tariffs, routing coordinates, naval mines, and the real-time posture of armed forces. In this environment, it is impossible to simply decree normalcy. It must be physically, legally, financially, and psychologically rebuilt from the ground up.
This explains why the reaction of shipowners remains profoundly cautious. They are not engaging in public debates with Trump. Instead, they are simply choosing not to move en masse. In this collective silence lies far deeper analysis than can be found in dozens of political communiqués.
A vessel that remains at anchor is voting against premature euphoria. A tanker waiting for formal signatures tells the market that words do not yet equate to safety. An insurer refusing to lower war premiums signals that the danger has not subsided. A bank demanding legal clarifications confirms that the sanctions are still very much alive.
The June 19 Intrigue: A Signature or the Start of a New Dispute
The formal signing ceremony on June 19 will not mark the finale of the crisis, but rather a test of its manageability. If the documents are signed without new caveats, if the US and Iran synchronize their interpretations, and if clear instructions emerge regarding routes, payments, mine clearance, and transit priority, the market will gain a chance at gradual recovery.
However, if it becomes evident after the signing that Washington and Tehran have conflicting understandings of the opening timeline, passage procedures, service fees, the role of the Iranian administration, and the deal’s link to Lebanon, the crisis will simply transition into a new phase. This phase will be legal and logistical rather than military, but it remains equally dangerous for the global economy.
This is particularly true if the Iranian formula of "within 30 days" is confirmed. In that case, June 19 will not be the day the strait opens, but rather the day a prolonged procedure begins under Iranian oversight. This would profoundly alter the political significance of the deal. Trump sells it as an immediate liberation; Iran can present it as a phased restoration under its own management.
Between these two versions stand the captains, the crews, and hundreds of vessels.
Hormuz as a Mirror of the New Global Disorder
The story of Hormuz today matters not just because oil, gas, and commodities flow through it. It matters because it illustrates the shifting nature of international order. The world no longer operates within a system where military might automatically dictates clear rules. On the contrary, force frequently produces deep uncertainty.
The US can declare a blockade and lift it. Iran can close the strait and speak of reopening it on its own terms. Israel can maintain its military footprint in Lebanon, while Iran views that as a breach of the deal. Shipowners may wish to depart but lack clarity on who guarantees their safety. Insurers may demand proof that does not yet exist. Sanctions may prohibit the very payments required for transit. Politicians may speak of peace, while logistics still abides by the rules of war.
Hormuz has become more than just a strait. It has evolved into a laboratory for a world where the global economy hinges on conflicting legal regimes, uncoordinated political declarations, and regional power balances.
This is no longer a classic blockade or a conventional peace accord. It is a hybrid reality: a partially open strait, partially active sanctions, a partially lifted blockade, a partially lingering military threat, a partially recognized Iranian oversight, and a partially restored trade flow.
In such a system, the most dangerous word is "completely."
Why Ships Distrust Words Until the Water Proves Safe
Shipping is one of the oldest and most pragmatic industries on Earth. It has no appetite for ideology and is entirely indifferent to beautiful press releases. It believes in charts, drafts, weather patterns, insurance certificates, port notifications, military advisories, and the concrete reality of safe passage.
Therefore, asking whether vessels in the Persian Gulf can trust Trump is an incomplete question. It is not about trusting the US president personally. It is about whether a political declaration can substitute for a system of institutional guarantees. The answer is obvious: it cannot.
The ships will trust neither Trump nor Ghalibaf. They will trust a route that successfully withstands dozens of transits. They will trust an insurer that slashes war premiums. They will trust a bank that authorizes a payment. They will trust a minefield map verified by specialists. They will trust the absence of fresh strikes in Lebanon. They will trust that the peace will not abruptly vanish after 60 days.
Until then, they will wait, proceed slowly, select their routes with extreme caution, and calculate every single mile.
A Finale Without a Finale: Open in Words, Closed by Fear
Today, Hormuz exists in a state of suspension. Formally, the path to reopening has been announced. Politically, the deal is framed as a breakthrough. Symbolically, US President Trump has already ordered the ships to move. Yet factually, the strait remains a zone of high risk.
Approximately 600 vessels are trapped inside. The southern route can accommodate only about 10% of normal traffic volume. The northern route is entangled with Iranian regulatory control and compliance hazards. The issue of mines remains unresolved. The structure of service fees is opaque. Opening timelines are interpreted differently: Washington points to June 19, while Iranian sources signal a window of up to 30 days. The truce is capped at 60 days. The Lebanon factor could shatter the agreement at any moment, as Israel does not intend to pull back, and Iran has already warned that continued strikes or occupation will be deemed a violation of the memorandum.
This is not peace. It is an intermission between two unknowns.
For Trump, the deal is a political asset. For Iran, it is an instrument to secure recognition of its role in the strait. For the oil market, it is a chance to curb panic. For shipowners, it is a high-stakes calculation. For crews, it is a matter of survival. For the global economy, it is a test of its capacity to distinguish a loud announcement from the genuine restoration of maritime safety.
The Strait of Hormuz may open. But it will not open with a single social media post, a single signature, or a single phrase like "let the oil flow." It will open only when the water becomes boring again—when tankers cease to be breaking news, when transiting the strait stops looking like a gamble with fate, and when captains look at a routine voyage plan rather than statements from politicians.
Until that happens, Hormuz remains not a corridor of peace, but a hornet’s nest of global trade. And every ship currently deciding whether to sail or wait asks the exact same question: can you trust words when the sea still remembers the war?
