Red Sea Shipping: Disruption and Contested Bab al-Mandab Approaches

Time window: Last 7 days · Audience: General analyst · Type: Situation report · DTG: 2026-10-05 10:26Z · Overall confidence: HIGH

BLUF

Very likely, commercial shipping risk around Bab al-Mandab will remain elevated over the next 0-14 days as fighting continues near the strait and operators weigh route risk. Houthi control of the waterway itself is not established: Yemen’s government says it retook Dhubab, while the Houthis deny that claim.

Executive summary

Yemen’s internationally recognised government has announced operations to retake Houthi-held territory. On 5 October, government forces said they had retaken Dhubab and positions near Bab al-Mandab; the Houthis disputed the claim. Reports of Houthi control of Mokha, Mayyun and other nearby positions, alongside accounts of fighting toward the Kahbub heights, leave the front line uncertain. Shipping evidence is also mixed: PortWatch recorded 22 transits on 20 September, while Sanaa’s Ministry of Transport claims a September daily average of 40. The latter figure is unverified and does not establish the current transit rate. Hapag-Lloyd has scheduled some Red Sea transits, subject to voyage-by-voyage security assessments.

Change from previous assessment

The central assessment of continued shipping disruption is unchanged, and confidence in the near-term shipping outlook remains medium. This brief adds the Yemeni government’s 5 October claim that it retook Dhubab, alongside the Houthi denial and reports of operations by the Homeland Shield Forces and Giants Brigades. The competing claims lower confidence in a precise front-line picture; the assessment of control remains low confidence. Sanaa’s Ministry of Transport claim of 40 daily transits in September adds a conflicting, unverified figure to the PortWatch count, but does not resolve current traffic levels. The forecast of continued fighting remains at medium confidence.

Key judgments

1. Very likely, commercial shipping risk around Bab al-Mandab will remain elevated over the next 0-14 days, and many operators will continue to favour routes around the Cape of Good Hope. PortWatch recorded 22 transits on 20 September, compared with about 30 per day before the latest escalation and about 70 before the 2023 Houthi attacks; rerouting around southern Africa has added up to 15 days to some journeys. The actual current transit rate is not established: Sanaa’s Ministry of Transport claims an average of 40 daily transits during September, but that figure is from an unknown source and is not directly comparable with PortWatch’s single-day count. Hapag-Lloyd has scheduled some Suez and Bab al-Mandab passages, with each voyage subject to a security assessment. Confidence is medium because reporting supports continued route caution, but the available transit figures conflict and are not current enough to confirm this week’s traffic. (Confidence: medium · ASSESSED)

• I&W: Confirm: PortWatch records an average below 30 Bab al-Mandab transits per day for seven consecutive days. (0-14 days)
• I&W: Break: PortWatch records at least 30 daily transits for seven consecutive days and Hapag-Lloyd completes a scheduled Suez and Bab al-Mandab passage. (0-3 months)

2. Likely, Houthi forces will retain positions at or near Mokha and Mayyun while Yemen’s government contests Dhubab; the reporting does not establish Houthi control of the Bab al-Mandab waterway itself. Multiple reports describe Houthi seizures of Mokha, Mayyun and nearby islands, but on 5 October the Yemeni government said it had retaken Dhubab and the Houthis denied that claim. Other reporting says Houthi forces were still trying to advance towards the Kahbub heights. These are competing battlefield claims, not independent confirmation of control. Confidence is low because territorial reporting is disputed and the reported recapture of Dhubab is not independently verified. (Confidence: low · ASSESSED)

• I&W: Confirm: Independent, geolocated reporting places Yemeni government forces on Dhubab’s roads while Houthi forces remain in Mokha or on Mayyun. (0-14 days)
• I&W: Break: Independent reporting verifies sustained Houthi control of Dhubab, Mokha and Mayyun, including the associated coastal access points. (0-14 days)

3. Very likely, fighting around Dhubab, Taiz and the approaches to Bab al-Mandab will continue over the next 0-14 days. On 4 October, Presidential Leadership Council chairman Rashad al-Alimi announced operations to retake Houthi-held territory. On 5 October, reporting attributed an operation with air cover in Dhubab to the Homeland Shield Forces and the Giants Brigades; the government also claimed it had retaken the district, which the Houthis denied. Government casualty and operation totals remain unverified: one account cited 1,747 Houthi fighters and 1,122 operations, while an earlier government account reported 700 fighters killed in 257 operations. Confidence is medium because the announced campaign and reports of operations are corroborated, but battlefield outcomes and reported totals rely on interested parties. (Confidence: medium · ASSESSED)

• I&W: Confirm: Independent reporting or geolocated footage records ground clashes or air strikes at Dhubab, Taiz or the Tor al-Baha front. (0-14 days)
• I&W: Break: No independently confirmed operations occur in Dhubab, Taiz or the Tor al-Baha front for 14 consecutive days, and neither side reports new deployments there. (0-14 days)

Outlook & scenarios

Contested coastal front, continued shipping caution (55%)

The fighting around Dhubab continues without either side establishing control of the Bab al-Mandab waterway. Houthi forces retain positions near Mokha and Mayyun, while Yemen’s government presses its operation along the coast. Most operators continue to favour longer routes, with only selected services making scheduled Red Sea passages after security reviews.

Government consolidates Dhubab and advances (25%)

Yemen’s government holds Dhubab and extends operations towards the Kahbub heights and other coastal approaches. The gains improve government access near Bab al-Mandab but do not remove the threat to shipping. Operators maintain cautious routing until control and maritime security are clearer.

Pause in fighting and selective route returns (15%)

A pause in Yemeni operations follows renewed engagement between the US and Houthi representatives. Some operators proceed with scheduled Red Sea voyages, but wider route returns remain gradual because the front line and Houthi commitments on shipping remain uncertain.

Low-probability, high-impact attack on commercial shipping (5%)

Houthi forces launch a sustained attack campaign against commercial vessels near Bab al-Mandab. Operators suspend scheduled passages and divert more traffic around southern Africa, deepening the disruption even if neither side establishes control of the strait.

Recommendations

1. For the next update, compare daily PortWatch transits with AIS-based vessel movements and record the measures separately. Do not combine PortWatch’s single-day count with Sanaa’s unverified monthly average as if they were equivalent.
2. Track control claims separately for Dhubab, Mokha, Mayyun and the Kahbub heights. Require independently geolocated reporting before describing a district, island or the strait itself as controlled by either side.
3. Monitor actual passages by Hapag-Lloyd’s SE1 service and other named operators, distinguishing completed voyages from announced schedules and recording any voyage-level security changes.
4. Attribute Yemeni government casualty and operation totals to the reporting official. Do not present the figures as verified, or combine the reported totals of 700 and 1,747 fighters killed.
5. Review UKMTO reports and operator advisories for incidents in the Gulf of Aden and southern Red Sea separately from attacks in the Strait of Hormuz. The reported incidents in those waterways do not by themselves establish a Bab al-Mandab attack.

Confidence & uncertainty

Overall confidence is high for the broad assessment that fighting has intensified and shipping operators face continuing route and security risk. Multiple major-media and wire reports cover the announced Yemeni campaign, coastal fighting and commercial rerouting. Confidence is lower on exact Bab al-Mandab transit volumes, control of individual coastal positions and government casualty totals. The transit figures use different time periods and sources, and the reported recapture of Dhubab is disputed.
