Oil surges as Strait of Hormuz tensions threaten fragile Middle East ceasefire
Approximately 20,000 seafarers remain stranded on 2,000 vessels in the Strait of Hormuz due to the conflict and closure.
Twenty thousand seafarers remain stranded on two thousand vessels

So oil jumped 6 percent in a single day. That's a real move. What's the mechanism here—is it just fear, or is there actual supply disruption happening right now?
Mimi
Both. The strait closure itself is the constraint—20 percent of global oil normally flows through there. But right now, the real problem is that ships aren't moving. Twenty thousand seafarers are stranded on two thousand vessels. The market is pricing in the possibility that this doesn't get resolved quickly.
Luke
But has any oil infrastructure actually been damaged yet, or is it just the one strike on the Fujairah facility? Because there's a difference between "a missile hit a petroleum site" and "global supply is actually cut."
Mimi
One missile did strike a petroleum facility in Fujairah, and a drone sparked a fire there. So yes, there's been direct damage to energy infrastructure. But you're right to push back—it's not a massive disruption yet. The price move is anticipatory.
Mark
Trump said the US military would guide ships through. Why hasn't that restored traffic?
Mimi
Because the underlying conflict hasn't been resolved. Even if the US says it will escort vessels, shipping companies and their insurers are still assessing the risk. One ship was already struck 36 nautical miles north of Dubai. That's not reassuring.
Luke
Wait—was that ship struck by Iranian fire, or was it a collision or mechanical failure? The source says a fire broke out in the engine room, but it doesn't say what caused the strike.
Mimi
That's a fair point. The source doesn't specify the cause of the strike. It just says it happened and a fire resulted.
Mark
So we're in a situation where the US has a blockade on Iranian ports, Iran is attacking shipping, and the ceasefire that supposedly existed is now fragile.
Mimi
Exactly. The ceasefire was already strained after the February 28 strikes. This week's escalation—the Iranian missiles and drones, the US destroying Iranian boats—suggests it's breaking down.
Luke
How long has the strait actually been closed? Since February 28?
Mimi
The source says Iran closed it after retaliating to the February 28 strikes, so yes, roughly since then. That's over two months of disruption.
Mark
And no one's found a way to reopen it yet.
Mimi
No. The blockade, the military exchanges, the stranded crews—it's all still unresolved.

- Iranian ballistic missiles, cruise missiles, and drones struck the UAE on May 4, with at least one missile hitting a petroleum facility in Fujairah — oil infrastructure burning in real time, not in projection.
- Brent Crude jumped 6% in a single session to $114.44 a barrel, as markets priced in the possibility that the Strait of Hormuz closure is not temporary but structural.
- The US military destroyed six Iranian small boats and imposed a port blockade, while President Trump pledged naval escorts for commercial vessels — but maritime traffic has not meaningfully resumed.
- A vessel was struck 36 nautical miles north of Dubai, its engine room ablaze, underscoring that the waterway remains an active conflict zone rather than a contested but navigable passage.
- Approximately 20,000 seafarers aboard 2,000 trapped vessels are caught in the deadlock — unable to deliver cargo, unable to go home, their lives paused at the intersection of energy economics and military brinkmanship.
At the narrow throat of the Strait of Hormuz, where one-fifth of the world's oil has long flowed as a matter of course, a military confrontation between Iran and the United States has forced markets to reckon with what was once considered a worst-case scenario. Brent Crude surged 6 percent to $114.44 a barrel on Monday as Iranian strikes on UAE oil infrastructure and an American naval blockade transformed a geopolitical standoff into a lived disruption of global commerce. Behind the price movements lie 20,000 seafarers stranded aboard 2,000 vessels — human lives suspended in a waterway that the world built its energy economy around, now rendered impassable by the logic of great-power conflict.
Oil markets opened the week in alarm as military escalation around the Strait of Hormuz pushed Brent Crude up 6 percent to $114.44 a barrel on Monday — a sharp single-session move reflecting fears that the world's most critical oil corridor could remain closed far longer than markets had hoped.
The crisis has been building since late February, when joint US-Israeli strikes on Iranian targets prompted Iran to close the strait and launch retaliatory strikes across the region. The US responded with a naval blockade on Iranian ports within the waterway, and President Trump pledged military escorts for commercial vessels. Neither measure has restored the flow of traffic.
On May 4, the UAE reported a coordinated Iranian assault: 12 ballistic missiles, three cruise missiles, and four drones, with its air defences intercepting most of them. At least one ballistic missile struck a petroleum facility in Fujairah, and a drone ignited a fire at the same site — a direct blow to oil infrastructure that confirmed the escalation was no longer theoretical. The US military reported destroying six Iranian small boats in response to attacks on commercial shipping, and a separate vessel was struck 36 nautical miles north of Dubai, its engine room catching fire.
By Tuesday morning, Brent futures had eased marginally to $113.54, but the anxiety underlying the market had not. Analysts warned that prolonged closure and further infrastructure damage remained live possibilities.
The human dimension of the standoff is quietly devastating. The International Maritime Organisation estimates that roughly 20,000 seafarers remain stranded aboard approximately 2,000 vessels, trapped in or unable to safely transit the strait. These crews — caught between a US blockade and Iranian military activity — cannot move their cargo and cannot return home, suspended in a geopolitical impasse that has effectively halted a critical artery of global commerce.
Oil prices surged at the start of the week as military tensions in the Middle East escalated and markets braced for disruption to one of the world's most critical shipping lanes. Brent Crude, the global benchmark for oil pricing, climbed 6 percent on Monday to $114.44 a barrel—a sharp move driven by reports of Iranian missile and drone strikes on the United Arab Emirates and deepening fears that the Strait of Hormuz, through which one-fifth of the world's oil passes, could remain closed for an extended period.
The current crisis traces back to February 28, when the US and Israel conducted joint military strikes against Iranian targets. Iran responded with its own strikes across the region and subsequently closed the Strait of Hormuz, the narrow waterway between Iran and Oman that serves as the artery for global oil trade. The US followed by implementing a blockade on Iranian ports within the strait, a move designed to pressure Iran economically and force a reopening of the passage. President Trump announced that the US military would escort commercial vessels through the route, but the promise has done little to restore confidence or traffic.
On Monday, May 4, the UAE reported a coordinated Iranian attack. The country's defence ministry said its air defence systems intercepted 12 ballistic missiles, three cruise missiles, and four drones. At least one ballistic missile struck a petroleum facility in Fujairah, in the eastern part of the emirate, and a drone sparked a fire at the site—a direct hit on oil infrastructure that underscored the real risk to energy supplies. The US military, for its part, reported destroying six Iranian small boats in response to Iranian attacks on commercial shipping.
Market analysts attributed the oil price jump to calculations that the strait could remain closed longer than initially expected and that more energy infrastructure could be damaged in the escalating exchange. By Tuesday morning, Brent futures had eased slightly to $113.54 a barrel, but the underlying anxiety remained. Despite Trump's commitment to guide vessels through the waterway, there has been no substantial resumption of maritime traffic. The UK Maritime Trade Operations reported that a ship was struck 36 nautical miles north of Dubai, with a fire breaking out in its engine room, though all crew members were accounted for.
The human toll of the standoff is mounting. The International Maritime Organisation reported that approximately 20,000 seafarers remain stranded aboard roughly 2,000 vessels trapped in or unable to safely transit the Strait of Hormuz. These crews are caught in a geopolitical deadlock, unable to move cargo or return home, their vessels effectively held hostage by the closure. The blockade and the military escalation have created a situation where the normal flow of global commerce has simply stopped, leaving both energy markets and the people who work the ships in a state of suspended uncertainty about when—or if—passage will resume.
