How Houthi Control of the Red Sea Could Reshape Global Trade

Saudi Arabia Is Trapped Between Two Chokepoints

The Houthis claimed a drone and missile strike on a military base in Sharurah, southern Saudi Arabia, on Sunday. The same weekend, the Yemeni government said its air force hit Houthi positions in Mocha and the Taiz region. The fighting roared back to life in July after three years of uneasy calm, and within weeks the picture it drew was stark: the Houthis now control every inch of Yemen’s Red Sea coastline, including the island chains that frame the Bab al-Mandab strait.

That is the detail most English-language headlines are missing. Bab al-Mandab is not a secondary waterway. It is the southern entrance to the Red Sea, and it sits on the route that ships use to reach Europe and the Mediterranean through the Suez Canal. More critically for Saudi Arabia right now, it is the fallback artery Riyadh has been using to move oil after Iran sealed off the Strait of Hormuz.

Iran’s blockade of Hormuz — the narrow passage through which most of Saudi Arabia’s oil historically flowed — forced Riyadh to reroute exports northward through the Red Sea. The plan was always provisional, a temporary corridor built to buy time and reduce dependence on a waterway Iran could threaten at will. Now the provisional route has come under direct threat from a non-state actor that has declared a maritime blockade of Saudi Red Sea ports and is already hitting targets inside Saudi territory.

Two chokepoints. One country. Neither under its control.

The logistical reality behind this is severe. Saudi Arabia’s East-West pipeline, commonly known as the Tanajib pipeline, has an estimated capacity of 5 million barrels per day running west to the Red Sea port of Yanbu. That is roughly a third of the kingdom’s total export throughput. If the Houthis can disrupt loading operations at Yanbu or blockade vessels in the strait — and they have demonstrated both capability and intent — Riyadh’s export ceiling drops overnight. The kingdom would be left trying to squeeze its entire surplus through a Hormuz that may already be partially controlled by Iran, or waiting for a diplomatic resolution that may never come.

MBS Asked Washington Twice. Trump Said No.

Axios reported this week that Saudi Crown Prince Mohammed bin Salman called Donald Trump twice, requesting American strikes on Houthi positions. Both times, the answer was no. Trump did not elaborate on Saturday when asked, telling reporters only that the Houthis had also reached out to Washington and “don’t want to fight with us,” adding that “everything’s gonna work out fine and dandy.” The phrasing was casual. The signal was not.

In 2025, the US conducted a seven-week bombing campaign against the Houthis after they attacked Red Sea shipping in solidarity with Hamas. That campaign ended with a negotiated ceasefire, but the Houthis kept firing at Israel and resumed maritime attacks this year after declaring their own blockade of Saudi ports. The precedent matters. Washington acted once when Red Sea shipping was disrupted and American commercial vessels were targeted. It did not act when pressed directly by an ally whose energy lifeline is being cut.

The difference may be calibration or it may be exhaustion. The administration appears to be recalibrating what it considers a direct American interest versus an allied problem. Either way, the consequence is the same: Saudi Arabia is being asked to manage a strategic threat without American backing, and it is doing so at a moment when its strategic options have never been narrower.

Who Wins, Who Loses

The Houthis win the most obvious terrain victory. They hold the Red Sea coast, the strategic islands, and the ability to project drones and missiles into southern Saudi Arabia. Their spokesperson Yahya Saree framed the Sharurah attack as retaliation for what he called “aggression against our nation and people.” Whether that is defensive posturing or preparation for further escalation remains unclear — the date of the operation was not specified. But the strategic geometry is unambiguous: whoever controls the Red Sea coast controls the leverage over Saudi energy flows.

Saudi Arabia loses the experiment in energy diversification. The Red Sea pipeline was always a workaround for Iranian pressure on Hormuz. Losing access to it raises the cost of every barrel Riyadh needs to move and narrows its options if Tehran tightens the noose further. The kingdom’s long-term strategy of reducing oil dependency through Vision 2030 now faces a compounding problem: even if domestic consumption grows as planned, export revenue will depend on navigating waters that increasingly belong to adversaries.

Yemeni civilians lose everything. The UN migration agency says 76,000 people have fled since July, a figure that quadrupled in a single week. About 1,400 have crossed into Djibouti. More than 500 have been killed. Mocha fell to the Houthis on Thursday; residents streamed toward Aden, the seat of the internationally recognized government. The humanitarian collapse that defined the early years of this war is returning with full force, and the international community’s response has been notably thin compared to previous cycles of displacement.

Europe and Asia lose the shipping lanes. The British UKMTO reported a projectile hit a vessel in the Strait of Hormuz on Sunday — details remain scarce, but the timing is unmistakable. With Iran controlling Hormuz and the Houthis pressing Bab al-Mandab, two of the world’s most critical energy corridors are simultaneously contested. The Suez Canal recorded a 40 percent drop in container traffic during the last Houthi blockade cycle. If that pattern repeats while Hormuz remains disrupted, global freight costs will absorb a shock that supply chains have not fully recovered from since the pandemic.

Second-Order Effects

The ripple effects extend far beyond immediate shipping disruptions. Insurance premiums for vessels transiting the Red Sea have already climbed sharply, and Lloyd’s of London is likely to issue updated war-risk surcharges that will apply across the board, not just to companies operating near conflict zones. That means goods moving through Suez — textiles, electronics, automotive parts from Asia to European ports — will carry a higher cost floor even when the direct threat subsides. Consumers in Rotterdam, Hamburg, and Marseille will feel it first.

Oil markets will price in the uncertainty before diplomacy catches up. Brent crude has already reacted to earlier escalations with volatility spikes of $3 to $5 per barrel. A prolonged dual-blockade scenario could push premiums higher, especially if Saudi exports are constrained precisely when global demand is peaking heading into the Northern Hemisphere winter. The strategic petroleum reserves of the IEA member states, depleted during the last energy crisis, may find themselves called upon again at a time when the geopolitical mechanics of the crisis are harder to isolate and resolve.

Regional actors will recalibrate their postures accordingly. Iran gains leverage not just over Saudi Arabia but over the entire Gulf Cooperation Council, which shares the same energy export dependency. Israel watches closely from the north, aware that a weakened Saudi Arabia shifts the balance of power in the peninsula. Turkey and Qatar, both of which maintain channels to the Houthis, will face renewed pressure to choose between mediating and being dragged into the conflict’s aftermath.

What Happens Next

The immediate risk is that Saudi Arabia, cornered and rebuffed by Washington, acts unilaterally. An independent Saudi strike campaign against Houthi positions would escalate the war beyond Yemen’s borders and draw in Iran’s proxy network in ways neither Riyadh nor Washington may want to manage. The longer-term risk is worse: a protracted stalemate where Saudi oil exports flow through increasingly contested waters, shipping insurance premiums climb, and global energy markets price in a persistent Middle East discount that erodes confidence in the region as a reliable supplier.

Trump’s dismissal of MBS’s requests suggests the US is unwilling to re-engage militarily. That creates a vacuum. Regional actors will fill it — Iran, Israel, possibly Turkey and Qatar through diplomacy — but none of them have an interest in stabilizing the Red Sea on Saudi terms. The arrangement that emerges will reflect their priorities, not Riyadh’s.

The numbers on the ground tell the story faster than any diplomatic statement. Seventy-six thousand displaced in two months. Five hundred dead. Two chokepoints under threat. The war in Yemen was never just a Yemeni war. It is a test of whether the Gulf’s energy architecture can survive when both its exits are contested — and so far, the answer has been no.
