The threat to seal off Bab-el-Mandeb creates a dangerous trap for Riyadh: the route designed to rescue Saudi oil from a blockade of the Strait of Hormuz has itself come under the sights of missiles and drones.
Just a week ago, a new turn in the Yemen conflict could have been mistaken for a localized skirmish on the periphery of a major Middle Eastern war. That is no longer possible. A Houthi missile strike on southern Saudi Arabia, threats to target vessels calling at Saudi ports, and the actual onset of an intimidation campaign in the Red Sea have transformed Yemen from a secondary front into a primary node of a global crisis.
The main point of interest lies not in whether the Houthis possess the physical capacity to lock down the Bab-el-Mandeb Strait. They lack a full-fledged navy, control over both shores, or the means to establish a classic naval blockade. Their real strength lies elsewhere: they know how to render shipping so dangerous and costly that insurance providers, shipowners, and captains will begin closing the strait through their own decisions.
This is precisely what is taking place. Following Houthi warnings, two tankers laden with Saudi oil destined for China and India turned around in the Red Sea and headed toward the Suez Canal, refusing to proceed south through Bab-el-Mandeb. Several vessels began turning off their transponders. This is what a modern blockade looks like: not a line of warships stretched across a strait, but a threat delivered via email, a few missiles on launchpads, and a sharp spike in risk pricing.
Missiles on Abha: The Truce Did Not End Where People Were Looking
On July 13, the Houthis announced a strike involving ballistic missiles and drones against Abha International Airport in southern Saudi Arabia. Saudi officials reported intercepting missiles directed at the kingdom's southern regions. This marked the first claimed Houthi attack on Saudi Arabia since the informal truce established in the spring of 2022.
However, distinguishing confirmed facts from propaganda narratives remains fundamentally important. The Houthis claimed they acted in response to a Saudi bombardment of Sanaa Airport. Meanwhile, the Ministry of Defense of Yemen's internationally recognized government reported that its own forces carried out the strike on the runway to prevent an Iranian aircraft from landing. Riyadh supports this government, yet direct participation by Saudi aviation in the strike was not publicly confirmed. Consequently, the framing of a "Saudi bombardment" remains a Houthi allegation rather than an established fact.
This detail shifts the political significance of the episode. The Houthis used the airport strike as more than just a pretext for retaliation. They effectively held Saudi Arabia accountable for any action taken by its Yemeni allies. In other words, Riyadh was presented with a new doctrine of collective responsibility: should forces of the internationally recognized government attack the Houthis, retaliation may follow against Saudi airports, ports, and energy infrastructure.
The movement's leader, Abdul-Malik al-Houthi, articulated this logic with utter clarity: an airport for an airport, a port for a port. He warned that Saudi oil and strategic assets would come under attack in the event of further escalation. This was no rhetorical improvisation. The Houthis have already proven capable of striking assets inside the kingdom, and Saudi leadership recalls the price of even a single successful breach of air defenses.
In March 2022, a strike on a Saudi Aramco petroleum distribution terminal in Jeddah triggered fires in two storage tanks. An even severer warning remains the September 14, 2019 attack on facilities in Abqaiq and Khurais, which temporarily shut down 5.7 million barrels per day of production. The Houthis claimed responsibility at the time, although the United States, Saudi Arabia, and several European nations attributed it to Iran. For the current crisis, disputes over authorship are secondary. The main reality is that the combination of Iranian technology, intelligence, rocketry, and regional partners can strike at the very heart of the Saudi oil network.
Blockade Without a Navy: How Fear Closes Straits Better Than Mines
On July 20, the Houthis declared a naval blockade against Saudi Arabia and warned maritime shipping entities that vessels loading or discharging Saudi oil could become targets. This expanded the conflict across three dimensions at once.
First, the targeted entities are no longer limited to ships affiliated with Israel, the United States, or the United Kingdom. Commercial traffic servicing Saudi ports as a whole could fall under attack. Second, the geographic focus of pressure is shifting from the southern Red Sea toward the kingdom's own port infrastructure. Third, the Houthis are tying the Yemeni front to the US-Iranian war, turning Saudi Arabia into a vulnerable party to the conflict regardless of whether Riyadh seeks direct involvement.
Legally, the Houthi declaration of a blockade carries almost no weight. A military blockade demands effective control, notification, the capacity to systematically deny access to a coastline, and adherence to international humanitarian law. The movement can supply none of these. Yet the market does not require a legally flawless blockade. The probability of a missile striking a tanker worth tens of millions of dollars, the risk of crew casualties, an oil spill, and a port closure lasting several days is more than enough.
The Houthis rely not on naval power, but on the economics of fear. Their missiles, drones, uncrewed surface vessels, naval mines, and coastal surveillance assets establish an asymmetrical deterrence model. A single low-cost strike craft forces a shipowner to account for the potential loss of vessel and cargo, prompts an insurer to raise premiums, and leads a charterer to choose between a hazardous short route and a costly detour around Africa.
The previous campaign demonstrated that the threat is not empty. Between 2023 and 2025, the Houthis targeted over one hundred commercial ships. In July 2025, two merchant vessels were sunk, resulting in the deaths of four mariners. In August of that year, the movement attacked an Israel-linked vessel off the coast of Yanbu, and in September a missile struck a Dutch cargo ship in the Gulf of Aden, killing one crew member. Following the ceasefire in Gaza in October 2025, attacks on merchant ships ceased, but the strike capability remained intact.
Thus, the Houthis do not need to sink tankers on a daily basis. A handful of demonstrative strikes suffices to make shipping companies act as though the strait were already closed. Two Saudi tankers turning back matters more than a dozen belligerent statements: the market received its first tangible proof that the threat alters routing.
Bypassing Hormuz Leads straight Under Houthi Missiles
Saudi Arabia spent decades constructing an infrastructure designed to reduce reliance on the Strait of Hormuz. Its centerpiece is the East-West Crude Oil Pipeline, connecting fields and processing centers in the kingdom's eastern region with the port of Yanbu on the Red Sea. The system's total throughput capacity reaches 7 million barrels per day, though roughly 5 million is available for export, as the remaining volume is required for domestic demand and Saudi refineries.
This infrastructure was intended as strategic insurance against a crisis in Hormuz. When transit through the strait plummeted due to the US-Iranian war, Saudi Arabia and the United Arab Emirates stood as the region's only major producers capable of diverting substantial oil volumes around the Persian Gulf's primary bottleneck. The UAE utilizes its pipeline to Fujairah; Saudi Arabia uses the route to Yanbu.
Yet geography delivered a bitter twist. Oil saved from Hormuz must still navigate the Red Sea and Bab-el-Mandeb if bound for Asia. Yanbu brings crude out to the kingdom's western coast, but it does not eliminate dependence on the second strait. As a result, the Houthis gained the ability to target not the primary production source, but the backup export pathway Riyadh relies upon during a major crisis.
This fuses the two straits into a unified system of leverage. Iran constrains shipping in Hormuz, while the Houthis threaten Bab-el-Mandeb. Even without daily operational direction between Tehran and Sanaa, the strategic effect operates in harmony: the alternative route ceases to function as an alternative.
According to the US Energy Information Administration, during the first quarter of 2026, roughly 14.6 million barrels per day of crude and refined products passed through Hormuz, compared to over 20 million in previous years. Over the same period, Bab-el-Mandeb saw roughly 5.4 million barrels per day. By comparison, in 2023 flow through Bab-el-Mandeb reached 9.3 million barrels before Houthi attacks drove a major portion of shipping toward the Cape of Good Hope.
These metrics illustrate why combining the shares of both straits to declare that the Houthis can instantaneously halt a quarter of global oil trade is mathematically incorrect. Portions of these flows overlap, portions are already rerouted, and portions can be offset by inventories and pipelines. Yet what matters most to the market is not the arithmetic of physically lost barrels, but the probability of a simultaneous disruption across both routes. Correlated risk - where one crisis amplifies another - is what triggers price shocks.
The Red Sea Becomes a Tax on Global Trade
A closure of Bab-el-Mandeb does not mean a complete shutdown of trade between Asia and Europe. Ships can transit around the Cape of Good Hope. Yet that detour adds thousands of nautical miles, roughly two weeks of travel time for certain routes, higher fuel consumption, increased fleet requirements, elevated crew costs, higher insurance, and greater emissions. In the first half of 2025, roughly 9.1 million barrels per day of crude and petroleum products were already moving around the Cape, well above pre-war baselines.
For the energy market, consequences ripple through a chain reaction. A longer tanker turn-around means the same number of vessels completes fewer voyages. Available tonnage capacity contracts, driving up freight rates. Insurance premiums climb, making every barrel more expensive. Companies build up buffer inventories against delays, intensifying short-term demand. Speculative capital overlays a geopolitical premium, driving prices away from current supply-demand fundamentals.
For containerized trade, the impact is even broader. The Suez Canal typically handles roughly 12 to 15 percent of global trade volume. Bab-el-Mandeb serves as the southern gateway to that route. When carriers divert around Africa, costs rise not only for oil and gas, but also for industrial components, electronics, automobiles, chemicals, and foodstuffs. Delivery schedules fall apart, container shortages emerge, corporations expand working capital, and manufacturers confront a problem thought to be a relic of the pandemic: goods are produced, but arrive too late and at too high a cost.
Europe is exceptionally vulnerable. For Europe, the Red Sea is the shortest artery to Asian manufacturing hubs and energy sources in the Persian Gulf. Asian buyers of Saudi crude find themselves in an equally difficult position: cargo dispatched from Yanbu must either risk passing Yemen or travel north through Suez and navigate around Europe and Africa - an economic absurdity for deliveries to China or India. This is why the turned-back tankers became symbolic of the crisis: they found themselves inside a geographic trap where every exit incurs additional expenses.
The Houthis recognize this vulnerability. Their goal is not necessarily a total cessation of maritime traffic. Maintaining a managed level of threat - where vessels continue to transit, but every voyage grows costlier, accumulating daily political pressure on Saudi Arabia and the United States - is far more rational.
The Saudi Dilemma: To Respond or Remain Silent
For Saudi leadership, this renewed escalation poses risks beyond oil revenue losses. It strikes at the core vision of Saudi strategy over recent years: transforming the kingdom from a state of perpetual conflict into an international hub for investment, logistics, tourism, technology, and major global developments.
Following a grueling campaign in Yemen, Riyadh sought an exit from the conflict. The military intervention launched in March 2015 failed to destroy the Houthis or restore government control over the entire country. On the contrary, the movement consolidated power, built up a missile arsenal, and evolved into a regional power. The informal truce of 2022 allowed Saudi Arabia to mitigate the threat of strikes on its cities and infrastructure, while negotiations were meant to lay the groundwork for a political roadmap.
Three Unfavorable Options for Riyadh
Riyadh now faces three bad choices.
The first is to launch large-scale strikes against the Houthis. This would demonstrate resolve, but it would almost certainly trigger a new missile campaign against Saudi airports, ports, power plants, and Saudi Aramco facilities. Saudi air defenses are capable of intercepting a significant share of incoming threats, but they must cover a vast territory. The Houthis need only a single successful strike to generate substantial economic and reputational fallout.
The second is to limit the response to diplomatic warnings. In this case, the Houthis might conclude that the kingdom fears escalation and is willing to tolerate the steady expansion of their demands. A weak response would raise the cost of any future agreement and deal a blow to Riyadh's allies within Yemen.
The third is to attempt to decouple the actions of Yemen's internationally recognized government from Saudi policy and demand restraint from its partners. Yet this would expose another problem: Saudi Arabia finances and supports forces it does not always fully control, whereas the Houthis view Riyadh as both the ultimate guarantor and the ultimate target.
The situation is further complicated by the fragmentation of the anti-Houthi camp. The Presidential Leadership Council, created in April 2022 following the transfer of power by President Abdrabbuh Mansur Hadi, remains dependent on Saudi assistance. The Southern Transitional Council, long backed by the UAE, dramatically expanded its control across the south in late 2025, after which its delegation in Riyadh announced the dissolution of the movement. However, STC supporters in Aden contested this decision, meaning southern separatism cannot be considered to have vanished entirely.
For Riyadh, this means that a new war against the Houthis would begin without a unified or reliable Yemeni partner. Southern separatists, proponents of a unified Yemen, tribal formations, the Islah Party, and forces affiliated with the UAE pursue divergent agendas. A military coalition exists on paper, but politically it is fractured.
Strong Abroad, Vulnerable at Home
The paradox of Ansar Allah is that its regional power far outstrips the economic sustainability of the territory under its control. The Houthis hold Sanaa and the country's northwest, home to roughly 60 to 65 percent of Yemen's population. They have established their own administration, security apparatus, tax system, mobilization machinery, and propaganda network. However, the primary oil and gas-producing regions lie beyond their grasp.
This leaves the Houthi model of governance structurally deficient. The movement can produce and acquire weaponry, maintain a security apparatus, and mobilize the populace, but it cannot sustain a functioning economy. Public sector salaries are paid sporadically, basic services are deteriorating, the private sector operates under the strain of levies and restrictions, and the humanitarian infrastructure relies on external funding.
By March 2026, over 18 million Yemenis faced acute food insecurity, more than 2 million children under five suffered from severe malnutrition, and roughly 40 percent of healthcare facilities were operating only partially or had closed altogether. The UN plan required 2.16 billion dollars to assist 12 million people.
The port of Hodeidah remains a vital lifeline for incoming supplies of food, fuel, and humanitarian aid to the north. Yet it is simultaneously exploited by the Houthis as an economic engine and military node, making it a repeated target for Israeli strikes. Damage to the port, power stations, and Sanaa Airport deepens the suffering of the civilian population, but it does not necessarily strip the movement of its missile capabilities right away. Therein lies the cruel logic of the conflict: the infrastructure essential to millions is destroyed far faster than an underground military network.
Israel has already demonstrated the capacity to strike senior Houthi administrative leadership. In August 2025, a strike on Sanaa killed the prime minister of the Houthi government, Ahmed Ghalib al-Rahwi, along with several cabinet ministers. Yet the movement's supreme leader, military command, and core missile structures remained intact. Eliminating civil officials dealt a blow to the administrative apparatus, but it did not decapitate Ansar Allah.
Thus, claims that Israel eliminated nearly the entire Houthi leadership are exaggerated. Key figures were killed, but the movement retained its capacity to launch strikes, mobilize followers, and make strategic decisions. Furthermore, external attacks allow it to suppress domestic dissent under the banner of resisting foreign aggression.
An Iranian Order or Sanaa's Own Game
Describing the Houthis as a mere Iranian proxy is analytical oversimplification, even if convenient. Tehran has spent decades supporting the movement with technology, arms, training, intelligence, and political backing. Without Iranian assistance, the Houthis would hardly have amassed such a diverse arsenal of ballistic and cruise missiles, attack drones, and anti-ship capabilities.
Yet dependency does not equal total subordination. Ansar Allah possesses its own domestic social base, tribal structure, ideology, history of conflict with the central government, and distinct interests. The movement negotiates with Saudi Arabia not solely on behalf of Iran, but to secure its own recognition, gain access to resources, lift restrictions, and entrench its rule over northern Yemen.
For this reason, engaging in a full-scale campaign in the Red Sea is not an automatic decision for the Houthis. By stepping into a major war alongside Tehran, they risk wrecking a potential deal with Riyadh, provoking new strikes from the United States and Israel, losing port infrastructure, and opening vulnerabilities for domestic adversaries to advance within Yemen.
On the other hand, failing to back Iran during a direct conflict would undermine the chief source of their military power and damage their image as a core component of the regional "Axis of Resistance." Moreover, threatening Saudi Arabia provides the Houthis with leverage to raise their negotiating price. They can offer de-escalation in exchange for economic concessions, access to Sanaa Airport, the easing of port restrictions, the payment of civil service salaries, and de facto political recognition.
Consequently, the current campaign can serve as an Iranian strategic maneuver and a self-interested Houthi bargaining tactic at the same time. Tehran gains a second point of leverage against global trade. The Houthis gain an opportunity to compel Riyadh into a deal on terms more favorable to themselves. These interests align, but they are not identical.
The Washington Front Runs Through the Gas Station
The threat to Bab-el-Mandeb carries direct domestic political implications in the United States. Federal congressional elections are scheduled for November 3, 2026. While Republicans control both chambers, their margin in the House of Representatives remains razor-thin, and Democrats expect to regain control of at least the lower house.
For US President Trump, the danger is that a conflict intended to display American strength could turn into a protracted war with mounting costs. The American electorate may support tough rhetoric against Iran, but it is far less tolerant of sustained expenditure, military casualties, and rising fuel prices.
In the week ending July 20, the average US retail price for all grades of gasoline rose to 4.131 dollars per gallon, up from 3.987 dollars the previous week. On July 21, Brent crude surpassed 91 dollars per barrel. While these figures do not signal immediate economic collapse, the speed of the shift is what matters politically. Voters do not evaluate the complex mechanics of the oil market; they react to the numbers on the gas station sign.
If shipping through Hormuz is disrupted while the threat in the Red Sea escalates, the White House faces a difficult dilemma. Lowering fuel prices requires reassuring markets and restoring maritime traffic. Yet achieving that requires either rapidly concluding the conflict with Iran, expanding military operations against the Houthis, or pressing Saudi Arabia to make concessions to a movement Washington designates as a terrorist organization.
Every option carries political toxicity. Negotiation risks appearing like a retreat. A new campaign in Yemen would demand financial resources, air defense assets, naval vessels, and airpower, without guaranteeing an end to the attacks. Pressuring Riyadh into a deal with the Houthis would erode the Saudi leadership's trust in the United States.
The Houthis cannot single-handedly dictate the outcome of US elections. Yet in a tightly contested partisan environment, they can amplify existing public dissatisfaction. A few weeks of high oil prices, supply chain disruptions, and new casualties can turn a distant strait off the coast of Yemen into a deciding factor for voters in Pennsylvania, Michigan, or Arizona.
Three Scenarios: Blackmail, Dual Blockade, or a Renewed Yemeni War
The first and currently most probable scenario is managed escalation. The Houthis will continue to threaten Saudi ports, periodically launch missiles and drones, issue warnings to maritime carriers, and drive up insurance premiums. At the same time, they will try to avoid mass casualties or a complete closure of the strait in order to preserve room for a deal. Saudi Arabia will limit its actions to interceptions, targeted retaliatory strikes, and back-channel negotiations.
This scenario favors the Houthis: they achieve maximum political leverage with minimal resources. It is also acceptable to Iran, as it keeps the global oil market under tension without forcing Tehran into directly defending its ally. However, it is inherently unstable. A targeting error, a strike on a civilian vessel, or a heavy loss of life among mariners could quickly shatter any control over escalation.
The second scenario is a coordinated campaign across both straits. Iran intensifies pressure in Hormuz while the Houthis transition from threats to systematic attacks on vessels linked to Saudi Arabia. The objective would not be the physical closure of all sea lanes, but a drastic reduction in traffic, soaring insurance premiums and oil prices, a shortage of tanker capacity, and political pressure on the United States.
This pathway would inflict the heaviest damage on the global economy. It would force Washington and its allies to launch a major naval operation, expand strikes across Yemen, and shield Saudi infrastructure. Yet even a powerful coalition could not guarantee absolute security for hundreds of vessels along thousands of miles of coastline. Defense is inherently more costly than offense, particularly when an adversary employs mobile launchers and inexpensive drones.
The third scenario is a return to full-scale war in Yemen. Saudi Arabia and the internationally recognized government conclude that the threat cannot be neutralized through an agreement and attempt to weaken the Houthis militarily. The United States and Israel launch strikes against missile depots, ports, command centers, and leadership figures. Anti-Houthi forces attempt to alter the frontlines on the ground.
Yet this path repeats the fundamental mistake of the 2015 campaign: assuming that air superiority automatically translates into political victory on the ground. The Houthis are adept at absorbing airstrikes, dispersing forces, and turning the destruction of civilian infrastructure into a tool for mobilization. A new war might destroy whatever remains of Yemen's economy without guaranteeing the elimination of the movement.
There is also a fourth, less visible scenario: a grand bargain. Saudi Arabia agrees to a package of economic and political concessions, the Houthis halt attacks on the kingdom and maritime traffic, and Iran uses the de-escalation as part of negotiations with the United States. While rational, this option demands a level of trust that is almost non-existent. Furthermore, any deal that cements Houthi authority in the north will draw fierce resistance from their Yemeni opponents and effectively codify the division of the country.
The Primary Target Is Not the Tanker, But Confidence
The Houthi threat to Bab-el-Mandeb illustrates how the nature of power in the Middle East has transformed. A movement with modest resources, governing the poorest region of a devastated nation, can influence oil prices, global trade routes, Saudi strategy, and US elections. To do so, it does not need to defeat the US Navy, capture Saudi oil fields, or occupy the strait.
It needs only to destroy confidence in the security of the route.
This represents the central failure of the previous regional architecture. The United States and the Gulf monarchies spent hundreds of billions of dollars on aircraft, warships, air defense systems, and bases, yet failed to eliminate an asymmetry where a missile or drone costing a fraction of the targeted asset dictates terms to the market.
Saudi Arabia finds itself in a particularly tight trap. The Hormuz crisis forces it to route oil toward the Red Sea. The Houthi threat makes the Red Sea dangerous. A military response risks a new war. Restraint looks like weakness. A deal strengthens a movement Riyadh spent a decade trying to undermine.
Therefore, current events cannot be described as a routine exchange of blows between Saudi Arabia and the Houthis. This is a battle over the pricing of global risk. Iran and its partners are attempting to demonstrate that they can exert simultaneous pressure on the region's two primary energy arteries. The United States and Saudi Arabia must prove the opposite without fracturing the global economy or being drawn into another endless war.
The Bab-el-Mandeb Strait may remain open on paper. But if tankers turn back, insurers retreat, and governments begin tallying political losses, the strait is already functioning as if closed. In the twenty-first century, maritime gateways are not locked by mines and warships alone. Sometimes they are locked by fear - and that is the weapon the Houthis wield best.
