Yemen’s Houthi rebels declared an immediate naval blockade on Saudi Arabia Monday, targeting the one Red Sea route still carrying Gulf crude to Asia. The group’s military spokesman called it an eye for an eye, days after Saudi warplanes bombed an airport in the rebel-held capital. The threat lands as Iran’s own closure of the Strait of Hormuz enters its fifth month.
Saudi Arabia built its Red Sea pipeline specifically to survive a Hormuz shutdown. The same widening war that closed one exit is now aimed at the other, and oil traders spent Monday deciding how seriously to take it.
Houthis Declare a Blockade ‘Effective Immediately’
The declaration came in a video statement from Yahya Saree, the Houthi military spokesman, who said the group was invoking a strict tit for tat against what it called Saudi Arabia’s own siege of Yemeni ports and airports.
We declare a maritime embargo against the criminal Saudi enemy, based on the equation of an eye for an eye, effective immediately upon the issuance of this statement.
Saree framed the move as retaliation for Saudi Arabia’s blockade of Houthi-held ports and airports and for last week’s strike on Sanaa International Airport. He warned that any further Saudi escalation would be met with what he called comprehensive and decisive escalation.
Saudi Arabia had not issued a public response by Monday evening, according to Al-Monitor. Two regional sources close to Riyadh said the kingdom was taking the threats from Iran and the Houthis very seriously and was aware the group was coordinating closely with Tehran over the Red Sea.
The Target Is Saudi Arabia’s Escape Valve From Hormuz
The blockade threat matters less as a Yemen story than as an energy one. Since Iran shut the Strait of Hormuz in late February, Saudi Arabia has leaned hard on an alternative built decades ago for exactly this scenario.
Saudi Aramco’s East-West pipeline, also called Petroline, runs from the Abqaiq processing complex near the Gulf coast to the Red Sea port of Yanbu. The line can carry up to 7 million barrels a day, according to the U.S. Energy Information Administration (EIA), the federal agency that tracks global energy flows. Saudi Arabia has shipped more than 4.5 million barrels a day of crude and fuel from Yanbu since April, roughly 70 percent of it bound for Asia, according to Kpler data cited by Al-Monitor and Reuters.
That pipeline only solves half the problem. Oil still has to leave the Red Sea, and the only way south is through Bab el-Mandeb, the strait the Houthis now say they are prepared to close.
| Chokepoint | Normal Share of Global Oil | Status as of July 20 | Workaround |
|---|---|---|---|
| Strait of Hormuz | About a fifth of global supply | Effectively closed since late February; crossings down roughly 85% | Saudi and UAE pipelines to the Red Sea and Fujairah |
| Bab el-Mandeb Strait | Roughly 7% of global output in June | Houthi missiles and drones positioned nearby, awaiting an order | Cape of Good Hope, adding about two weeks of transit |
| Yanbu pipeline route | Up to 7 million bpd capacity | Carrying about 4.5 million bpd since April, 70% to Asia | None; the route ends at Bab el-Mandeb |
A Four-Year Truce Broken Over an Airport
The immediate spark was narrow and specific. On July 13, Saudi Arabia struck Sanaa International Airport to stop a flight from Tehran carrying a Houthi delegation from landing, an operation this site covered as Yemen’s internationally recognized government blocking an Iranian plane. The Houthis blamed Riyadh for the strike and fired missiles at an airport in Abha, southern Saudi Arabia, within days.
That exchange broke a truce that had held for four years. Abdulmalik al-Houthi, the movement’s top leader, laid out the logic in a speech on July 16.
“The real equation is Sana’a Airport for Riyadh Airport, airports for airports, ports for ports, and a blockade for a Saudi blockade,” al-Houthi said, warning that “all Saudi oil facilities and vital installations are targets for our missiles and drones” if the kingdom escalates further.
Days earlier, the group had already vowed to break the Saudi siege regardless of the cost, a pledge that now reads as a preview of Monday’s declaration.
Tehran’s Hand Behind the Timing
The Saudi-Houthi flare-up did not happen apart from the wider Iran war. Three sources told Reuters on July 16 that Iran had instructed the Houthis to close the Red Sea to shipping if the United States strikes Iran’s power infrastructure, a threat President Donald Trump made in a July 14 interview.
A source close to the Houthis said the group had already completed preparations, positioning missiles and drones near Bab el-Mandeb in Yemen’s highlands overlooking Hodeidah and the Gulf of Aden, and was waiting for the order. Representatives of Iran’s Islamic Revolutionary Guard Corps (IRGC), the elite force that runs Tehran’s regional militia network, already stationed in Yemen would control that decision, the source said.
Trump had put a date on his own threat. “Next week it gets really bad for them because next week comes the power plants,” he said, in comments reported by Reuters. This site previously reported on how Saudi Arabia was weighing the risk to its own oil lifeline before Monday’s blockade made that risk concrete.
Who Pays if Both Chokepoints Shut?
A simultaneous closure of Hormuz and Bab el-Mandeb would not stay contained to Saudi Arabia and Yemen. It would hit refiners, insurers and consumers thousands of miles from either strait, and the exposure is already visible in the numbers.
- Asian refiners – Japan, India, China and South Korea take most Yanbu-loaded crude and would face roughly a month of delay if tankers divert around Africa, said Matt Smith, commodity research director at Kpler.
- Saudi Arabia’s own export math – more than 3 million barrels a day of crude currently routed to Asia through the Red Sea could be forced onto the longer Cape route, estimated Richard Bronze, an analyst at the consultancy Energy Aspects.
- Egypt’s Suez Canal – revenue had only recently climbed back to $449 million in a single month after October’s Gaza ceasefire, following a stretch in which President Abdel Fattah el-Sisi said cumulative losses reached $10 billion. Egypt also leans on Egypt’s own 2.5-million-barrel-a-day SUMED pipeline as a partial workaround, but it cannot absorb Red Sea volumes on its own.
- Diesel and jet fuel buyers – European refining margins for diesel have already surged to a record above $65 a barrel, a sign the market is pricing distress before any tanker is actually hit.
John Paisie, president of the consultancy Stratas Advisors, put the ceiling in blunt terms. “It undermines the whole global economy,” he said. “At some point, you could have a global recession.”
Oil Markets Barely Blink, for Now
Given the stakes, Monday’s price move looked almost muted. Brent crude jumped as much as 4 percent overnight, touching $91.42 a barrel, its highest level since June 11, before easing back to settle at $88.87, up 0.87 percent on the day. U.S. West Texas Intermediate crude added 0.44 percent to $82.85.
Two forces pulled in opposite directions. Overnight, Brent spiked after Washington confirmed at least three U.S. service members had died in fighting with Iran, the ninth straight night of American strikes. Prices then eased after Iran’s foreign ministry spokesman, Esmail Baghaei, said Tehran could still pursue talks with Washington based on its own interests.
Mediators had floated a 10-day ceasefire proposal to Iran on Monday, aimed at reviving the interim deal both sides signed June 17 and that later collapsed after Trump declared it dead at a NATO summit. Hormuz flows have deteriorated regardless. Supertanker crossings fell to an average of two a day last week, down from eight a day in late June and early July, satellite imagery reviewed by Reuters showed, and overall vessel crossings are down roughly 85 percent from pre-conflict levels, per Kpler. Hormuz alone carried 20.9 million barrels a day in 2023, underlining how much volume is now stranded.
Analysts disagree less on direction than on scale. Jorge Leon, head of geopolitical analysis at Rystad Energy, said a rebound in prices would be substantial if the ceasefire fails and Hormuz stays largely shut while the Bab el-Mandeb threat grows. Paisie put a number on it, estimating oil could climb back above $115 to $120 a barrel in that scenario. Giovanni Staunovo, a commodities analyst at UBS, said the blockade could put large parts of Saudi Arabia’s Bab el-Mandeb-dependent exports directly at risk.
What We Know and What’s Still Unconfirmed
- Confirmed: The Houthis declared the blockade effective immediately Monday; Saudi Arabia struck Sanaa airport on July 13; Hormuz has been effectively closed since late February; Reuters reported the Iran-Houthi coordination over a Red Sea trigger on July 16.
- Unconfirmed: How the Houthis intend to enforce the blockade in practice, since Rystad’s Leon noted the group has not explained its enforcement mechanism; whether the IRGC will actually issue the order at Bab el-Mandeb; and whether the newly floated 10-day ceasefire proposal survives past this week.
The Next Ten Days Decide What Happens
Every thread in this story now runs through the same narrow window. Trump’s threatened strikes on Iran’s power plants were promised for the week that started Monday. The IRGC controls the order to shut Bab el-Mandeb, and that order is explicitly tied to whether those strikes happen.
Mediators are simultaneously pushing a 10-day ceasefire proposal meant to revive the collapsed June truce. Which of those two tracks moves first will decide whether the world spends the second half of 2026 with one major oil chokepoint closed, or two.
Frequently Asked Questions
What Is the Bab el-Mandeb Strait?
The Bab el-Mandeb Strait is an 18-mile-wide passage between Yemen and the Horn of Africa that links the Red Sea to the Gulf of Aden, according to the EIA. It funnels tankers into two channels just two miles wide each, making it one of the most exposed chokepoints in global shipping.
Why Does Saudi Arabia Ship Oil Through the Red Sea at All?
Saudi Arabia built the East-West pipeline decades ago specifically to move crude from its Gulf coast to the Red Sea port of Yanbu without transiting the Strait of Hormuz. Aramco temporarily expanded that capacity to 7 million barrels a day in 2019, a buffer the kingdom is now leaning on heavily.
Has Saudi Arabia Responded to the Blockade?
Not publicly as of Monday evening. Al-Monitor reported that Saudi Arabia had yet to issue a statement, though regional sources close to Riyadh said the kingdom was treating the Iranian-Houthi coordination as a serious threat.
Could Oil Prices Really Reach $200 a Barrel?
A senior Houthi official warned Iran’s Press TV that prices could spike to $200 a barrel if Hormuz and Bab el-Mandeb closed together. That figure is a warning from an interested party, not an independent forecast. Analysts quoted by Reuters and Al-Monitor put a more grounded ceiling nearer $115 to $120 a barrel.
