Brent crude crossed $100 a barrel, rising 6.45 per cent to $101.10 while West Texas Intermediate gained 5.37 per cent to $91.49, after Houthi forces struck the Saudi tankers Encelia and Layla with missiles and drones in the Red Sea on July 23, 2026.2 The National 2026-07-23 Brent rose 6.45 per cent to $101.10 and WTI 5.37 per cent to $91.49 after Houthi missiles and drones struck the Saudi tankers Encelia and Layla; five Saudi tankers reversed course with four redirecting toward Suez, the US completed a 12th consecutive night of strikes on Iran, Goldman Sachs said Brent could exceed $120 by the fourth quarter, and RBC strategist Helima Croft cited a worst case above the 2008 peak of $146. Open source Saudi Arabia's state news agency confirmed the Encelia was hit near the port of Jizan and reported a fire at the bow; the claimed strike on the Layla was not independently confirmed at the time.4 The Jerusalem Post 2026-07-23 Saudi state news agency SPA confirmed the Encelia was struck near Jizan on July 23, 2026, with a fire at the bow, while the claimed strike on the Layla was not independently confirmed; five tankers rerouted away from Bab el-Mandeb on Wednesday and three Saudi laden tankers bound for China and India reversed course on Tuesday, alongside Iran's near closure of the Strait of Hormuz. Open source By July 24 Brent was quoted at $100.65, its highest since late May.1 Al Jazeera 2026-07-24 Brent reached $100.65 a barrel, its highest since late May, as the Houthis enforced a naval blockade on Saudi shipments through Bab el-Mandeb; Windward analyst Michelle Bockmann said enforcement appears keyed to vessel affiliation, Chinese flagged vessels have reportedly passed, US gasoline averaged $4.09 and diesel $5.34 a gallon, and Chinese imports have recently fallen. Open source The stake is not the barrels lost on two hulls. It is that Saudi Arabia had already shifted more than 70 per cent of its exports away from the Persian Gulf to the Red Sea port of Yanbu because of the fighting around the Strait of Hormuz, which means the Red Sea was the workaround, not a second option.3 OilPrice.com 2026-07-23 Houthi forces claimed strikes on the Encelia and Layla in the Bab el-Mandeb strait citing violation of the blockade decision, with Brent above $98 after a five session run of gains of nearly 20 per cent in about two weeks, and Saudi Arabia having redirected more than 70 per cent of its exports from the Persian Gulf to Yanbu. Open source We assess with moderate to high confidence that the market is now repricing the loss of Saudi Arabia's alternate route rather than any confirmed loss of supply, and that this repricing holds as long as the Houthi blockade is credibly enforced, regardless of how much oil is actually interdicted.
The geography is the story
The Houthis declared a maritime embargo on Saudi Arabia on Monday, July 20, framing it as retaliation for attacks they attributed to Saudi Arabia on Sanaa International Airport.5 Al Jazeera 2026-07-20 The Houthis announced a maritime embargo on Saudi Arabia on Monday, July 20, 2026, in retaliation for attacks they attributed to Saudi Arabia on Sanaa International Airport; the 1,201 km East-West Petroline runs from Abqaiq to Yanbu, Yanbu shipments average roughly 4 million barrels a day, and Bab al-Mandeb petroleum flows reached 7.4 million barrels a day in June, about 7 per cent of global output. Open source Three days later they claimed the two tanker strikes, saying the vessels had violated the blockade decision.3 OilPrice.com 2026-07-23 Houthi forces claimed strikes on the Encelia and Layla in the Bab el-Mandeb strait citing violation of the blockade decision, with Brent above $98 after a five session run of gains of nearly 20 per cent in about two weeks, and Saudi Arabia having redirected more than 70 per cent of its exports from the Persian Gulf to Yanbu. Open source The declaration and the strike together are what matter: an announced rule plus one visible enforcement action is enough to change insurer and owner behaviour without sinking a single ship.
The route being threatened is the one Riyadh built precisely for this scenario. The East-West Petroline runs 1,201 kilometres from Abqaiq in the east to Yanbu on the Red Sea coast, and shipments out of Yanbu now average roughly 4 million barrels a day.5 Al Jazeera 2026-07-20 The Houthis announced a maritime embargo on Saudi Arabia on Monday, July 20, 2026, in retaliation for attacks they attributed to Saudi Arabia on Sanaa International Airport; the 1,201 km East-West Petroline runs from Abqaiq to Yanbu, Yanbu shipments average roughly 4 million barrels a day, and Bab al-Mandeb petroleum flows reached 7.4 million barrels a day in June, about 7 per cent of global output. Open source That pipeline exists so Saudi crude can reach buyers without passing Iran. Its exit, however, is the Red Sea, and the Red Sea narrows at Bab al-Mandeb, where total petroleum flows reached 7.4 million barrels a day in June, about 7 per cent of global output.5 Al Jazeera 2026-07-20 The Houthis announced a maritime embargo on Saudi Arabia on Monday, July 20, 2026, in retaliation for attacks they attributed to Saudi Arabia on Sanaa International Airport; the 1,201 km East-West Petroline runs from Abqaiq to Yanbu, Yanbu shipments average roughly 4 million barrels a day, and Bab al-Mandeb petroleum flows reached 7.4 million barrels a day in June, about 7 per cent of global output. Open source With Iran having brought the Strait of Hormuz close to unusable, both ends of the kingdom's export system are now contested at once.4 The Jerusalem Post 2026-07-23 Saudi state news agency SPA confirmed the Encelia was struck near Jizan on July 23, 2026, with a fire at the bow, while the claimed strike on the Layla was not independently confirmed; five tankers rerouted away from Bab el-Mandeb on Wednesday and three Saudi laden tankers bound for China and India reversed course on Tuesday, alongside Iran's near closure of the Strait of Hormuz.

Shipowners moved before governments did. Five tankers rerouted away from Bab al-Mandeb on Wednesday, and three Saudi laden tankers bound for China and India reversed course on Tuesday, before the strikes were even claimed.4 The Jerusalem Post 2026-07-23 Saudi state news agency SPA confirmed the Encelia was struck near Jizan on July 23, 2026, with a fire at the bow, while the claimed strike on the Layla was not independently confirmed; five tankers rerouted away from Bab el-Mandeb on Wednesday and three Saudi laden tankers bound for China and India reversed course on Tuesday, alongside Iran's near closure of the Strait of Hormuz. Open source Five Saudi tankers turned back in the aftermath, four of them redirecting toward the Suez Canal instead.2 The National 2026-07-23 Brent rose 6.45 per cent to $101.10 and WTI 5.37 per cent to $91.49 after Houthi missiles and drones struck the Saudi tankers Encelia and Layla; five Saudi tankers reversed course with four redirecting toward Suez, the US completed a 12th consecutive night of strikes on Iran, Goldman Sachs said Brent could exceed $120 by the fourth quarter, and RBC strategist Helima Croft cited a worst case above the 2008 peak of $146. Open source We assess with high confidence that these diversions, not the damage to the Encelia, are the mechanism moving the price: the market is pricing voluntary route abandonment, which can happen far faster and at far greater scale than any missile campaign.
The move also did not come out of nowhere. Oil had already run for five consecutive sessions, gaining nearly 20 per cent in roughly two weeks, and the United States completed a twelfth consecutive night of strikes on Iranian targets around the same window.3 OilPrice.com 2026-07-23 Houthi forces claimed strikes on the Encelia and Layla in the Bab el-Mandeb strait citing violation of the blockade decision, with Brent above $98 after a five session run of gains of nearly 20 per cent in about two weeks, and Saudi Arabia having redirected more than 70 per cent of its exports from the Persian Gulf to Yanbu.

Open source The tanker attacks landed on a market that was already positioned for escalation, which is one reason a single confirmed hit produced a move of more than six per cent.
Who gains, who loses
Saudi Arabia is the clearest loser, and the reason is structural rather than reputational. Having concentrated most of its exports through Yanbu to escape Hormuz, the kingdom now faces a threat on the escape route itself, with no third corridor of comparable scale.3 OilPrice.com 2026-07-23 Houthi forces claimed strikes on the Encelia and Layla in the Bab el-Mandeb strait citing violation of the blockade decision, with Brent above $98 after a five session run of gains of nearly 20 per cent in about two weeks, and Saudi Arabia having redirected more than 70 per cent of its exports from the Persian Gulf to Yanbu.

Open source Every diverted cargo adds Cape of Good Hope steaming time or Suez transit risk to a barrel that was already travelling the long way round.
Asian refiners buying Saudi crude are the next tier of loss. The tankers that reversed course on Tuesday were bound for China and India, which means the disruption reaches the two largest incremental buyers of Gulf crude directly and immediately.4 The Jerusalem Post 2026-07-23 Saudi state news agency SPA confirmed the Encelia was struck near Jizan on July 23, 2026, with a fire at the bow, while the claimed strike on the Layla was not independently confirmed; five tankers rerouted away from Bab el-Mandeb on Wednesday and three Saudi laden tankers bound for China and India reversed course on Tuesday, alongside Iran's near closure of the Strait of Hormuz. Open source US households absorb it at the pump, where the national gasoline average stood at $4.09 a gallon and diesel at $5.34, with GasBuddy's Patrick De Haan attributing part of the diesel strain to Ukrainian drone strikes on Russian refineries and Russia's export ban.1 Al Jazeera 2026-07-24 Brent reached $100.65 a barrel, its highest since late May, as the Houthis enforced a naval blockade on Saudi shipments through Bab el-Mandeb; Windward analyst Michelle Bockmann said enforcement appears keyed to vessel affiliation, Chinese flagged vessels have reportedly passed, US gasoline averaged $4.09 and diesel $5.34 a gallon, and Chinese imports have recently fallen. Open source Diesel is the tell: it is the fuel of freight and agriculture, so a diesel squeeze propagates into general prices in a way a gasoline spike does not.
Who gains: producers outside the threatened corridors, whose barrels now carry a routing premium simply for not needing Bab al-Mandeb or Hormuz, and tanker owners, whose vessels earn on longer voyages and elevated war risk premiums. China appears to gain in a narrower and more specific way. Chinese-flagged vessels have reportedly transited without interdiction, and Windward's Michelle Bockmann has framed the open question as whether Chinese owned tankers at Yanbu are allowed through Bab el-Mandeb.1 Al Jazeera 2026-07-24 Brent reached $100.65 a barrel, its highest since late May, as the Houthis enforced a naval blockade on Saudi shipments through Bab el-Mandeb; Windward analyst Michelle Bockmann said enforcement appears keyed to vessel affiliation, Chinese flagged vessels have reportedly passed, US gasoline averaged $4.09 and diesel $5.34 a gallon, and Chinese imports have recently fallen. Open source That is a single analyst's framing of an emerging pattern rather than a confirmed policy, so treat it as low confidence. If it holds, the blockade functions less as a supply cut than as a reassignment of who gets to buy Saudi crude cheaply, which is a very different trade.
The counter-case
The strongest argument against the thesis is that almost no oil has actually stopped moving. One tanker was confirmed struck, with a bow fire and no reported loss of the vessel; the second claim was unverified.4 The Jerusalem Post 2026-07-23 Saudi state news agency SPA confirmed the Encelia was struck near Jizan on July 23, 2026, with a fire at the bow, while the claimed strike on the Layla was not independently confirmed; five tankers rerouted away from Bab el-Mandeb on Wednesday and three Saudi laden tankers bound for China and India reversed course on Tuesday, alongside Iran's near closure of the Strait of Hormuz. Open source Enforcement so far appears selective, keyed to vessel affiliation rather than cargo, which is the behaviour of a group applying political pressure rather than closing a strait.1 Al Jazeera 2026-07-24 Brent reached $100.65 a barrel, its highest since late May, as the Houthis enforced a naval blockade on Saudi shipments through Bab el-Mandeb; Windward analyst Michelle Bockmann said enforcement appears keyed to vessel affiliation, Chinese flagged vessels have reportedly passed, US gasoline averaged $4.09 and diesel $5.34 a gallon, and Chinese imports have recently fallen. Open source A blockade that lets most hulls through is a risk premium, and risk premiums decay. Brent had traded below $98 only a day earlier, which shows how much of the move is sentiment that can unwind.3 OilPrice.com 2026-07-23 Houthi forces claimed strikes on the Encelia and Layla in the Bab el-Mandeb strait citing violation of the blockade decision, with Brent above $98 after a five session run of gains of nearly 20 per cent in about two weeks, and Saudi Arabia having redirected more than 70 per cent of its exports from the Persian Gulf to Yanbu. Open source For the bearish case to win, the Houthis would need to stop hitting ships while the Iran conflict cools, at which point insurers reprice and the diverted tankers return to Bab al-Mandeb within weeks. Demand is the other soft spot: Chinese import volumes have recently fallen, and a weaker buyer of last resort caps how far a supply scare can carry.1 Al Jazeera 2026-07-24 Brent reached $100.65 a barrel, its highest since late May, as the Houthis enforced a naval blockade on Saudi shipments through Bab el-Mandeb; Windward analyst Michelle Bockmann said enforcement appears keyed to vessel affiliation, Chinese flagged vessels have reportedly passed, US gasoline averaged $4.09 and diesel $5.34 a gallon, and Chinese imports have recently fallen. Open source We hold the main assessment at moderate to high rather than high confidence for exactly these reasons.
What to watch
- A second confirmed hit. If a Saudi laden tanker is struck and independently confirmed within the next two to four weeks, the blockade converts from a threat into a rule and the risk premium becomes structural; a month with no confirmed strike would mark the July 23 move as a spike, not a repricing.4 The Jerusalem Post 2026-07-23 Saudi state news agency SPA confirmed the Encelia was struck near Jizan on July 23, 2026, with a fire at the bow, while the claimed strike on the Layla was not independently confirmed; five tankers rerouted away from Bab el-Mandeb on Wednesday and three Saudi laden tankers bound for China and India reversed course on Tuesday, alongside Iran's near closure of the Strait of Hormuz. Open source
- Yanbu loadings. Track whether shipments from Yanbu hold near the recent average of roughly 4 million barrels a day through August. A sustained fall is the first hard evidence that Saudi export capacity, not just Saudi shipping cost, has been reduced.5 Al Jazeera 2026-07-20 The Houthis announced a maritime embargo on Saudi Arabia on Monday, July 20, 2026, in retaliation for attacks they attributed to Saudi Arabia on Sanaa International Airport; the 1,201 km East-West Petroline runs from Abqaiq to Yanbu, Yanbu shipments average roughly 4 million barrels a day, and Bab al-Mandeb petroleum flows reached 7.4 million barrels a day in June, about 7 per cent of global output. Open source
- Chinese owned hulls at Bab el-Mandeb. If Chinese owned tankers keep transiting unmolested while others divert, the blockade is a discriminatory tariff on Saudi buyers rather than a supply cut, and that should show up as widening differentials between Asian and European delivered prices.1 Al Jazeera 2026-07-24 Brent reached $100.65 a barrel, its highest since late May, as the Houthis enforced a naval blockade on Saudi shipments through Bab el-Mandeb; Windward analyst Michelle Bockmann said enforcement appears keyed to vessel affiliation, Chinese flagged vessels have reportedly passed, US gasoline averaged $4.09 and diesel $5.34 a gallon, and Chinese imports have recently fallen.

- The $120 line by the fourth quarter. Goldman Sachs has said Brent could rally above $120 by the fourth quarter if supply disruptions persist, and RBC's Helima Croft has flagged a worst case above the 2008 peak of $146.2 The National 2026-07-23 Brent rose 6.45 per cent to $101.10 and WTI 5.37 per cent to $91.49 after Houthi missiles and drones struck the Saudi tankers Encelia and Layla; five Saudi tankers reversed course with four redirecting toward Suez, the US completed a 12th consecutive night of strikes on Iran, Goldman Sachs said Brent could exceed $120 by the fourth quarter, and RBC strategist Helima Croft cited a worst case above the 2008 peak of $146. Open source Brent holding above $100 into September would mean the market believes the persistence condition; a slide back into the $80s would mean it does not.
- US strike tempo on Iran. The strikes had run twelve consecutive nights as of July 23.2 The National 2026-07-23 Brent rose 6.45 per cent to $101.10 and WTI 5.37 per cent to $91.49 after Houthi missiles and drones struck the Saudi tankers Encelia and Layla; five Saudi tankers reversed course with four redirecting toward Suez, the US completed a 12th consecutive night of strikes on Iran, Goldman Sachs said Brent could exceed $120 by the fourth quarter, and RBC strategist Helima Croft cited a worst case above the 2008 peak of $146. Open source A pause is the single cheapest de-escalation signal available, and it would likely take the Houthi campaign's intensity with it.
The lesson buyers are now pricing is that redundancy built inside one geography is not redundancy. Saudi Arabia spent decades building a pipeline to avoid one chokepoint and arrived at another, and the next capital cycle in Gulf export infrastructure will be judged on whether it escapes the map at all.
