Two Tankers Full of Saudi Oil Just Turned Around in the Red Sea — and the Houthis Didn't Have to Fire a Single Shot

Summary

The Houthi Crisis? Two tankers loaded with Saudi crude reversed course in the Red Sea on Tuesday. Neither had been fired on. The Xin Long Yang, a very large crude carrier hauling two million barrels toward China, turned north for Suez instead of heading south through Bab el-Mandeb. The Rodos, a smaller tanker carrying Saudi crude for India, made the same turn. The Houthis had warned a day earlier that ships loading at Saudi ports could be targeted anywhere within their reach, and that was enough. Nobody had to shoot at either ship for the threat to already be working. That’s the part the coverage keeps missing. The debate over whether the Houthis can actually seal the strait is the wrong debate. A blockade doesn’t need to physically stop a tanker to change what the tanker does. It just needs to make the direct route look like a bad bet to the people who insure it, crew it, and own it. Riyadh’s Escape Route Leads to Another Chokepoint When the Strait of Hormuz turned into a war zone, Saudi Arabia did the obvious thing and pushed crude west, to the export terminal at Yanbu on the Red Sea coast. The kingdom has shipped more than 4.5 million barrels a day out of Yanbu since April, something like 70 percent of it bound for Asia. For a while this looked like real redundancy, a second route standing in for the one Iran had effectively closed. Under the normal route, those Asia-bound barrels clear Bab el-Mandeb and continue on to their destination directly. The alternative, the one the Xin Long Yang and the Rodos had begun taking, is to sail north through Suez, across the Mediterranean, and then around the whole of Africa to get to Asia anyway. Fully laden VLCCs can’t make that trip through the canal without first discharging part of their cargo into the SUMED pipeline, which has a fixed capacity of its own. Riyadh spent considerable money building a way around one chokepoint threatened by Iran. It just watched two tankers carrying its crude demonstrate how expensive the fallback really is. A Month Is a Lot of Tanker More than 3 million barrels a day of that Yanbu-to-Asia crude could get forced onto the long route around Africa, and some Asian refiners could face roughly another month’s wait for cargo that would otherwise have gone straight through. The arithmetic is rough but worth doing anyway. A VLCC typically carries about two million barrels. Diverting 3 million barrels a day for an extra month works out to something like the equivalent of forty-five fully laden VLCC cargoes tied up in additional transit at any given time, before anyone counts the empty return legs, the refueling stops, or the owners who simply decide Saudi business isn’t worth the exposure anymore. This isn’t a new pattern. The United Nations trade body UNCTAD found that Red Sea rerouting after the Houthis’ first campaign pushed global ton-miles, meaning the distance each ton of cargo actually travels, up nearly 6 percent in 2024, close to three times the growth in cargo volume itself. Ships didn’t stop moving goods. They just started spending a lot more time doing it, which quietly ate into how much capacity was left over for everything else. Apply that same pressure to several million barrels a day of Saudi exports specifically, and spare tanker capacity doesn’t erode gradually. It can go fast. None of this requires the Houthis to touch a single barrel of oil. Make the short route expensive and risky enough, and the fleet does the rest of the damage on its own, one long detour at a time. Warships Cannot Restore a Shipping Schedule Washington’s instinct will be to hand this to the Navy, and American ships can intercept missiles and escort convoys well enough. What they can’t do is compel an owner to accept a charter whose insurance costs and crew risk have become commercially unacceptable, and they can’t conjure a replacement supertanker out of nowhere when the existing ones are weeks out of position on the wrong side of Africa. The earlier Red Sea campaign is the reason to stay skeptical here rather than optimistic. The Trump administration’s 2025 bombing campaign against the Houthis, aimed at restoring free passage through the strait, cost well over a billion dollars. By early 2025, two commercial vessels had already been sunk in the fighting since 2023, and further vessels were sunk later that year even after a ceasefire had briefly taken hold. The Houthis repeatedly demonstrated that they retained the ability to resume missile and drone attacks on shipping. Much of the industry kept avoiding the route anyway. None of that makes naval power irrelevant. It just means a strike package that destroys launchers but leaves tanker schedules in disarray has accomplished less than the battle-damage assessment suggests. What This Actually Tests The real test isn’t whether the blockade survives contact with the Fifth Fleet. It’s whether the global tanker fleet can absorb a second chokepoint fight stacked on top of Hormuz without the slow, unglamorous loss of shipping capacity turning into a shortage that has nothing to do with how much oil sits in the ground. Brent initially moved less than 1 percent on the blockade announcement, trading near $89, before climbing above $91 as the regional fighting intensified. Freight rates, canceled fixtures, and how many owners still call at Yanbu next month will say more than a single day of trading ever could. Saudi Arabia’s pipelines can keep oil moving west. They cannot create the additional ships required when the normal voyage to Asia suddenly becomes several weeks longer. That capacity problem will still be there after the blockade announcement has left the headlines, and Washington has not yet shown that it understands how to solve it.

Iran war briefing: Trump threatens to strike Iranian nuclear site

○ 1 source

Iran war briefing: Trump threatens to strike Iranian nuclear site - Donald Trump threatened to renew strikes on Iran's heavily fortified "Pickaxe Mountain" nuclear site, which experts believe is likely too deep for current US bunker-buster missiles.

- The US Defence Secretary, Pete Hegseth, estimated the war's financial toll at $37.5bn and is seeking an additional $67bn from Congress, while at least 18 US troops have died and over 400 have been injured, according to US officials. - Iran claimed to have struck US military targets in Kuwait and Amazon’s central data infrastructure in Bahrain, in response to the US’s alleged attack on the "civilian facilities of Darkhovey".

- US military concluded its eleventh consecutive night of strikes on Iranian military infrastructure, targeting operations centres, maritime capabilities, aircraft hangars, drone storage facilities and logistics infrastructure to degrade Iran's ability to threaten shipping in the Strait of Hormuz.

- US Secretary of State Marco Rubio warned that Iran's demand to control and levy tolls on ships transiting the Strait of Hormuz would endanger the global economy.

Another Hormuz: How Iran's Houthi Card In Red Sea May Torch Oil Markets

○ 1 source

The Iran-backed Houthis in Yemen announced on Monday that they would block maritime trade with Saudi Arabia, a move that could further strain global energy markets already affected by Iran's blockade of the Strait of Hormuz. It remains unclear whether the Houthis would resume attacks on shipping as part of their proposed naval embargo on Saudi Arabia.

ALSO READ: Iran Targets Amazon Data Infrastructure In Bahrain, Attacks US Military Base In Jordan The Red Sea has emerged as a vital substitute route for Gulf oil and other goods, with Hormuz already hampered. A significant disruption would result in the simultaneous closure of both of the Middle East's main oil export routes.

The majority of Gulf oil and other exports were halted by Iran's partial blockage of the Strait of Hormuz following an attack by Israel and the United States on February 28, which increased prices and caused a global energy shock. In response, Saudi Arabia shifted over 70% of its regular daily petroleum exports to Yanbu, a port on the Red Sea.

Ships from Yanbu travel north via the Suez Canal on their way to Europe. Bab el-Mandeb is the southern route taken by those travelling to Asia. Shipments from Yanbu have surged from about 973,000 barrels per day a year ago to around 4 million bpd in recent weeks, according to Kpler and Signal Ocean.

Kpler data also showed oil volumes passing through Bab el-Mandeb rose from 4.2 million bpd to 7.4 million bpd in June, helping keep global oil prices in check. According to a report from Reuters last week, Saudi Arabia is thinking about extending its pipeline for crude oil to the Red Sea shore.

Gulf oil shipments remained unaffected even after the Houthis began attacking vessels in the Red Sea in November 2023. ARE THE HOUTHIS CLOSING RED SEA ENERGY ROUTES ON IRAN'S BEHALF? In the 1990s, the Houthis became a military, political, and religious force in northern Yemen, waging guerrilla warfare against the Sanaa government.

They have been engaged in a civil war with the internationally recognised government supported by Saudi Arabia for almost ten years, and they have used drones and missiles to attack Gulf neighbours. But until last week, when Yemen's internationally recognised government claimed to have attacked Sanaa airport to prevent an Iranian plane from arriving, a 2022 truce between the nation's warring factions remained largely intact.

Houthis blamed Saudi Arabia, who retaliated by firing missiles at Abha airport in the mountainous southwest of the kingdom. Then, in an appearance on Iran's Press TV website, Mohammad al-Farah, a prominent Houthi leader and member of the politburo, threatened to seal Bab el-Mandeb if the situation continued to worsen.

Iran supports the Houthis as part of its "Axis of Resistance" in the region, which also includes Iraqi Shi'ite militias and Hezbollah in Lebanon; however, its connections to the Yemeni movement are less obvious than those of those other groups.

Trump Faces Crucial Decision On Iran War, Says Report Unlike Hezbollah and the Iraqi parties, the Houthis do not see Iran's supreme leader as their supreme religious authority. Despite the group's ideological alignment with Iran, their aims are mostly domestic.

The United States claims that Iran, with assistance from Hezbollah, has provided the Houthis with weapons, money, and training. The Houthis claim to create their own weaponry and deny being an Iranian proxy. The extent to which the group is acting on Iran's behalf or in accordance with its own geopolitical interests regarding Bab el-Mandeb and the Red Sea is unclear.
