The rapid Houthi advance along Yemen’s Red Sea coast has transformed a long-running conflict into a wider strategic problem for Saudi Arabia and its Gulf neighbours. By gaining positions near the Bab el-Mandeb Strait and threatening an alternative route for Saudi oil exports, the Iran-aligned group has undermined one of the few options available to Gulf producers when traffic through the Strait of Hormuz is disrupted.
The significance of the advance lies less in the territory captured than in the choices it creates. Gulf states now face a difficult balance between relying on military protection from the United States, accepting higher economic risks from continued confrontation, or opening more direct channels with Iran to protect trade and energy flows. None of these options offers a straightforward solution, particularly while the conflict continues to spread across several fronts.
Houthi Expansion Turns an Alternative Route Into a Vulnerability
The Houthis have rapidly expanded their control along Yemen’s Red Sea coastline, capturing the port of Mocha and advancing toward strategically important islands around the Bab el-Mandeb. Their gains give the group a stronger position near one of the main maritime gateways between the Red Sea and the Gulf of Aden, increasing the risks for commercial shipping and for Saudi Arabia’s use of Red Sea export infrastructure.
The timing is particularly important because the Strait of Hormuz has already become heavily disrupted by the wider conflict with Iran. Saudi Arabia had sought to reduce its exposure by moving more crude through its East-West pipeline toward Red Sea terminals. That arrangement was intended to provide an alternative route for exports that would otherwise have travelled through Hormuz. The pipeline has now been damaged and temporarily closed after an attack, weakening precisely the alternative route that had become more valuable during the crisis.
This creates a strategic problem that cannot be solved simply by reopening one waterway. If Hormuz remains difficult to use while the Bab el-Mandeb becomes increasingly insecure, Gulf exporters face pressure at both ends of the Arabian Peninsula. The vulnerability is therefore becoming geographical rather than confined to a single piece of infrastructure.
The Houthi advance does not mean that the group can automatically shut the Bab el-Mandeb or permanently prevent commercial shipping from using the Red Sea. However, control of territory and nearby islands can improve its ability to threaten vessels, launch attacks and impose additional security costs. That alone can affect shipping decisions, insurance rates and the willingness of commercial operators to use the route.
Saudi Arabia Faces a Security Problem Washington Cannot Easily Solve
For Saudi Arabia, the immediate temptation is to seek stronger American military intervention. Riyadh has relied heavily on the United States for security cooperation, intelligence and military support, and Washington has a direct interest in keeping global energy markets functioning. Yet the latest developments show why American protection has limits.
Reports that Saudi Crown Prince Mohammed bin Salman sought US approval for strikes against the Houthis but did not receive it have added to uncertainty over Washington’s willingness to open another military front. The United States is already deeply involved in the conflict with Iran, while the security of Hormuz remains a major concern. Expanding the campaign into Yemen could therefore increase the geographical scope of the war without guaranteeing that the underlying threat would disappear.
The Houthis have also demonstrated over many years that superior military technology does not necessarily translate into a decisive victory in Yemen. The group survived years of Saudi-led military intervention and has developed missile and drone capabilities that allow it to threaten targets well beyond territory under its direct control.
That history matters for current calculations. A major US campaign against the Houthis could damage their military infrastructure, but it would not automatically remove the political and geographical factors that have allowed the group to survive. For Washington, the question is therefore not simply whether it can strike the Houthis, but whether doing so would produce a durable improvement in regional security.
For Saudi Arabia, the problem is even more immediate. The kingdom has to protect its territory, energy infrastructure and economic transformation plans while avoiding a conflict that could impose additional costs on its oil exports. The Houthi advance has consequently exposed the limits of a strategy based primarily on military deterrence.
Gulf States Have More Reason to Talk to Iran
This is where the diplomatic dimension becomes more important. Gulf governments have strong reasons to remain wary of Iran, but they also have practical reasons to maintain communication with Tehran. Iran occupies the northern side of the Gulf and has significant influence over the security environment surrounding Hormuz. Its regional relationships also extend to armed groups capable of affecting shipping and infrastructure.
The postponement of planned talks between Iran and Gulf states in Oman illustrates the difficulty of this approach. The meeting was intended to explore arrangements concerning Hormuz and regional security, but disagreements prevented it from proceeding as scheduled. The delay does not establish that Gulf governments have abandoned diplomacy. Instead, it demonstrates how difficult it is to negotiate while military operations and attacks are continuing.
For Gulf states, engaging Iran does not necessarily mean accepting Iranian demands or abandoning their relationship with Washington. It can instead provide another channel for reducing risks that military alliances alone cannot eliminate. The more vulnerable energy routes become, the greater the practical value of maintaining communication with the government capable of influencing events around Hormuz.
The same logic applies to Yemen. Saudi Arabia can continue supporting forces opposed to the Houthis, but the latest territorial gains suggest that restoring the previous balance will not be easy. If the Houthis retain control of important sections of the Red Sea coast, Saudi Arabia may have to consider whether an exclusively military response can protect its interests over the long term.
Trump’s Oil Position Adds Another Layer to the Calculation
The Gulf states also have to assess what the United States ultimately wants from the conflict. President Donald Trump recently suggested that Washington could remain in Iran and benefit from its oil resources, comparing the possibility with the US approach toward Venezuela. He also said he expected the conflict to end later in the year and argued that energy prices would fall sharply once the war ended.
The remarks matter because they introduce uncertainty about the relationship between American military objectives and energy policy. Trump did not announce a decision to seize Iranian oil, and his comments should not be treated as evidence that such a policy has been adopted. Nevertheless, publicly raising the possibility of retaining access to Iranian oil gives the conflict an additional economic dimension.
For Gulf governments, this could complicate an already difficult strategic calculation. Their security relationship with Washington remains important, but they also have direct economic interests in stable oil exports, predictable shipping and lower regional tensions. If the conflict continues to threaten both Hormuz and Red Sea routes, Gulf governments cannot assume that American military power alone will restore the conditions required for economic stability.
The Houthi advance therefore creates pressure on several levels simultaneously. It threatens an alternative oil route, strengthens the group's bargaining position, increases the risks surrounding Red Sea shipping and gives Iran greater regional leverage without requiring Tehran itself to control the Yemeni coastline directly.
The uncomfortable choice for Gulf states is consequently not simply between fighting the Houthis and negotiating with Iran. It is between competing forms of risk. Continued confrontation could preserve strategic pressure on Iran but expose Gulf economies to prolonged disruption. Greater diplomacy could reduce immediate risks but require difficult compromises with a regional rival. Dependence on American military intervention could provide protection, but Washington's reluctance to expand the war demonstrates that such protection has limits.
The central strategic change is that geography has made the Gulf states more dependent on diplomacy precisely when the conflict is making diplomacy harder. The Houthi advance has shown that controlling or threatening one side of the Arabian Peninsula can affect energy security on the other. That gives the conflict in Yemen significance far beyond Yemen itself and leaves Gulf governments with fewer options for protecting their economic interests without engaging the wider regional power struggle.
