A nightmare scenario for global supply chains
In the long history of energy markets, few moments have concentrated so much anxiety into so short a span of time. Through March 2026, the closure of the Strait of Hormuz by Iran — and the gathering threat to the Bab el-Mandeb strait — has pushed Brent crude to its largest monthly gain ever recorded, as the world confronts what it means when the arteries of global commerce come under simultaneous pressure. The market is not speculating about scarcity; it is pricing in a scarcity that has already begun, and the diplomatic distance between Washington and Tehran offers little comfort to those watching the gauges rise.
- Iran's closure of the Strait of Hormuz has removed roughly one-fifth of the world's oil supply from normal circulation, sending Brent crude up 59% in a single month — the largest monthly gain in the contract's history.
- A Kuwaiti supertanker carrying 2 million barrels was struck at Dubai port in what officials described as an Iranian attack, raising fears of an oil spill and signaling that the conflict has moved from threat to direct action.
- Houthi missile launches toward Israel have placed the Bab el-Mandeb strait under fresh threat, and analysts warn that simultaneous pressure on both chokepoints would constitute a nightmare scenario for global supply chains.
- Saudi Arabia has scrambled to reroute exports through the Red Sea port of Yanbu, with volumes surging from 770,000 to 4.658 million barrels per day — a workaround that reveals just how constrained the situation has become.
- President Trump has threatened to obliterate Iran's energy infrastructure if Hormuz is not reopened, yet the White House simultaneously claims talks are progressing — a contradiction that leaves markets with no clear signal of resolution.
Oil prices rose for a fourth straight day on Tuesday, with Brent crude reaching $115.04 per barrel and West Texas Intermediate climbing to $105.96 — both at their highest levels in weeks. The driving force is singular and stark: Iran has effectively closed the Strait of Hormuz, the passage through which roughly one-fifth of the world's oil normally flows. Brent has now surged 59 percent over the course of March, its largest monthly gain ever recorded. WTI has climbed 58 percent, its biggest monthly jump since May 2020. These are not gradual market adjustments — they are the arithmetic of genuine scarcity.
The crisis deepened on Tuesday when Kuwait Petroleum Corporation confirmed that its tanker Al Salmi, loaded with 2 million barrels of crude, was struck in a suspected Iranian attack while docked at Dubai port. The incident raised immediate fears of an oil spill and underscored that the conflict has moved well beyond rhetoric. Days earlier, Houthi forces aligned with Iran launched missiles toward Israel, intensifying concern about the Bab el-Mandeb strait — the narrow passage connecting the Red Sea to the Gulf of Aden and a vital corridor for ships traveling between Asia and Europe. Analysts have begun describing the situation as a 'twin chokepoint' crisis.
Saudi Arabia has responded by rerouting crude exports through the Red Sea port of Yanbu, with volumes reaching 4.658 million barrels per day last week — up dramatically from an average of 770,000 barrels per day in January and February. The scale of that shift is itself a measure of how severely normal routes have been disrupted.
Diplomatically, the picture remains contradictory. President Trump threatened to 'obliterate' Iran's energy infrastructure if Tehran does not reopen Hormuz, even as the White House claimed that back-channel talks were making progress — a tension that suggests the two governments are saying very different things in public and in private. Market analysts are not reassured. The prevailing view, as one Marex analyst put it, is that the two sides remain far too far apart for any near-term resolution, and the oil market is pricing in that uncertainty with no sign of retreat.
Oil prices climbed for the fourth consecutive day on Tuesday, driven by fears that the widening Middle East conflict could choke off a significant portion of the world's energy supply. Brent crude futures for May delivery rose $2.26 per barrel, or 2 percent, to $115.04, marking the highest price since mid-March. The more actively traded June contract settled at $108.96. U.S. West Texas Intermediate crude jumped $3.10, or 3 percent, to $105.96 a barrel, its strongest level since early March. The momentum reflects a single, stark reality: Iran has effectively closed the Strait of Hormuz, the waterway through which roughly one-fifth of the world's oil normally flows.
The numbers tell the story of panic. Brent crude has surged 59 percent over the course of March, the largest monthly gain in the contract's history. West Texas Intermediate has climbed 58 percent this month, its biggest monthly jump since May 2020. These are not gradual shifts. They are the market's way of pricing in genuine scarcity. The closure of Hormuz, combined with threats to other critical chokepoints, has created what analysts are calling a "twin chokepoint" crisis—a scenario in which two of the world's most vital energy arteries could be simultaneously disrupted.
The threat is not theoretical. On Tuesday, Kuwait Petroleum Corporation reported that its fully loaded crude tanker Al Salmi, capable of carrying 2 million barrels of oil, was struck by what officials described as an Iranian attack while docked at Dubai port. The incident raised immediate concerns about potential oil spills in the region. Days earlier, on Saturday, Houthi forces aligned with Iran had launched missiles at Israel, raising fresh alarm about the Bab el-Mandeb strait, the narrow passage linking the Red Sea to the Gulf of Aden and a crucial route for ships traveling between Asia and Europe through the Suez Canal. If the Houthis successfully blockade this strait as well, the disruption to global energy flows would be severe.
Saudi Arabia has already begun adapting to the crisis. The kingdom has rerouted crude exports away from the Persian Gulf, sending them instead through the Red Sea port of Yanbu. Last week, volumes moving through this alternative route reached 4.658 million barrels per day, according to shipping data firm Kpler—a dramatic increase from the average of 770,000 barrels per day that flowed through the same route in January and February. This shift, while necessary, is itself a sign of how constrained the situation has become.
The diplomatic backdrop remains murky. On Monday, U.S. President Donald Trump issued a stark warning, saying the United States would "obliterate" Iran's energy infrastructure if Tehran did not reopen the Strait of Hormuz. The threat came after Iran dismissed American peace proposals as unrealistic and after Tehran launched missile strikes on Israel. Yet the White House simultaneously claimed that talks with Iran were progressing well, suggesting that what Iran says publicly differs sharply from what it communicates privately to U.S. officials. The contradiction hints at the uncertainty surrounding any near-term resolution.
Market analysts remain skeptical. Edward Meir, an analyst at Marex, captured the prevailing sentiment: the markets see no clear exit from the conflict because the two sides remain far apart in their demands, despite the optimistic public statements coming from Washington. Tim Waterer, chief market analyst at KCM Trade, was more blunt about the stakes. If both the Strait of Hormuz and the Bab el-Mandeb strait fall under simultaneous pressure, he said, it would represent a nightmare scenario for global supply chains. The oil market is pricing in that possibility, and it is showing no signs of backing down.

The Hearth Conversation Another angle on the story
Why does the closure of one waterway—the Strait of Hormuz—move oil prices so dramatically?
Because it's not just any waterway. A fifth of the world's oil passes through it. When that supply is suddenly threatened, every refinery, every country, every person who depends on energy has to recalculate. The market is saying: we don't know how much oil will actually reach us, so we're paying more for what we can get.
But couldn't oil come from other places?
It can, and it is. Saudi Arabia is already rerouting tankers through the Red Sea. But that route is longer, more expensive, and now it's also under threat from Houthi missiles. You're not just paying more for oil—you're paying for uncertainty and risk.
The White House says talks are going well. Why don't markets believe them?
Because the gap between what Iran is demanding and what the U.S. is willing to offer appears to be enormous. Markets don't respond to optimistic rhetoric. They respond to what they can actually see happening on the ground—tankers being struck, missiles being fired, chokepoints being closed.
What happens if both the Hormuz and the Bab el-Mandeb straits are blocked at the same time?
That's the scenario nobody wants to contemplate. You'd have two of the world's three most critical energy passages under simultaneous pressure. Prices would spike further. Supply chains would fracture. Every economy that depends on imported oil would feel it immediately.
Is there a way out of this?
Theoretically, yes—through negotiation or military intervention. But right now, both sides are too far apart. Trump is threatening to destroy Iran's oil infrastructure. Iran is closing shipping lanes. Neither side appears ready to step back.
