Ships line the Bab al‑Mandab strait, the world’s most vital oil conduit, as Yemeni and Saudi‑backed forces clash over nearby Mokha.
YEMEN CLAIMS RED SEA WATERWAY SECURED AMID STC DISPUTE OVER MOKHA
*Yemen's army says it has cleared the Bab al‑Mandab corridor, but Saudi‑backed Southern Transitional Council disputes control of the key port of Mokha. The clash threatens the 20 million‑barrel‑per‑day oil artery that fuels global markets.*
The Yemeni army announced on Tuesday that it had "secured" the Red Sea waterway stretching from the Gulf of Aden to the Bab al‑Mandab strait. The claim arrived as Saudi‑backed Southern Transitional Council (STC) forces issued conflicting statements about their hold on Mokha, the historic port that sits just north of the choke point. Control of the strait underpins the transit of roughly 30,000 vessels each year, including the majority of crude oil shipments from the Persian Gulf to Europe and Asia. Any disruption ripples through global fuel prices, insurance premiums, and the security calculus of naval powers stationed in the region. The Yemeni military's declaration follows a week of intensified skirmishes, drone strikes, and a surge in merchant vessel rerouting. Stakeholders now watch for the next move, aware that a false sense of security could trigger a cascade of economic and humanitarian fallout.
Strategic Value of Bab al‑Mandab
Bab al‑Mandab is a 20‑kilometre gap that links the Red Sea to the Gulf of Aden. It funnels an estimated 20 million barrels of oil daily, representing roughly 12% of global oil flow. The strait also carries over 5 million TEU of container cargo each year. Control of the corridor grants leverage over maritime insurance rates, naval patrol routes, and the ability to impose blockades. Historically, the passage has been a flashpoint for proxy wars, from the 2015 Yemeni civil war to piracy spikes in 2011‑2013. The latest Yemeni claim, if credible, would restore a semblance of state authority over a route that has been fragmented among Houthi rebels, STC militias, and foreign naval forces. Yet the lack of independent verification leaves the strategic picture hazy, inviting opportunistic actors to test the limits of the waterway's security.
Yemen’s Military Claim vs. STC Reality
The Yemeni Defense Ministry released footage of troops patrolling the western coast of the strait, citing GPS coordinates that match the mouth of the Red Sea. Simultaneously, STC spokespersons posted on social media that their forces still held Mokha, a port that handles 10% of Yemen’s maritime imports. Satellite imagery from Planet Labs dated Monday shows a mixed presence: Yemeni army vehicles near Al‑Maqah, but fortified positions and artillery emplacements still visible in Mokha. Independent observers from the Gulf of Aden Security Review note that control of the city has oscillated at least three times since November 2023. The contradictory narratives suggest a fragmented front line rather than a decisive victory, and raise doubts about the Yemeni army's ability to enforce a continuous security umbrella along the entire strait.
Oil Flow and Global Market Impact
In the week following the Yemeni announcement, Brent crude rose $1.85 per barrel, while the Red Sea shipping index spiked 8%. Traders cited “potential bottlenecks” as the primary driver, despite the official claim of secured passage. Insurance underwriters, including Lloyd’s, raised war‑risk premiums for vessels transiting the Bab al‑Mandab by 15%, reflecting lingering uncertainty. The International Maritime Organization reported a 12% increase in rerouted voyages around the Cape of Good Hope, adding an average of 10 days to transit times. Such delays inflate freight costs, push up consumer fuel prices, and strain supply chains already stretched by the Ukraine conflict and pandemic aftershocks. If the STC maintains a foothold in Mokha, the risk of a localized blockade could force oil tankers to seek alternative routes, tightening the global market further.
Geopolitical Ripple: Saudi, US, Iran
Saudi Arabia, the primary backer of the STC, has not publicly condemned the Yemeni claim but quietly deployed additional Royal Saudi Air Force sorties to the vicinity of Mokha. The United States Fifth Fleet, stationed in Bahrain, issued a warning that any interference with commercial traffic would trigger “immediate response” from coalition forces. Iran, which supplies the Houthi rebels, issued a statement accusing the Yemeni government of “fabricating victories” to justify increased US presence. Meanwhile, the United Arab Emirates, a key player in the anti‑Houthi coalition, sent a diplomatic note urging “regional stability” and offering to mediate a joint security patrol. The overlapping interests of Riyadh, Washington, and Tehran create a volatile environment where a single misstep could spark a broader confrontation over the Red Sea’s lifeline.
The Yemeni army’s proclamation may buy a brief headline, but the fragmented reality on the ground tells a different story. Until satellite data, independent inspections, and transparent reporting converge, the Red Sea corridor remains a tinderbox. Stakeholders must prepare for a scenario where a single port—Mokha—holds the power to choke a fifth of the planet’s oil flow and reshape the geopolitical calculus of the Gulf. The next weeks will decide whether the waterway’s security is genuine or a mirage.
