BLUF

Commercial shipping through Bab el-Mandeb is likely to remain disrupted over the next 0-14 days, but a broad physical closure is unlikely on the evidence provided. Houthi attacks and shipping rerouting are reported, while current transit levels through the strait remain unconfirmed.

Executive summary

Reporting for 15-22 October describes renewed Houthi attacks around Bab el-Mandeb, higher freight and war-risk premiums, and traders considering Cape of Good Hope diversions that add 10-14 days to some voyages. Egypt reports Suez Canal losses exceeding $10 billion. Houthi claims of coastal gains conflict with Yemeni government claims of recaptured territory, leaving control near the strait unresolved. The available reporting supports sustained disruption, not a verified physical closure.

Change from previous assessment

The core assessment is unchanged from the 21 October brief: disruption is likely to persist, while a broad physical closure remains unlikely. This brief adds reported Cape diversions with 10-14 day voyage extensions, increased southern Red Sea insurance premiums, Egypt's reported Suez losses above $10 billion, and a reported shortfall in Aspides escort assets. Confidence in the persistence assessment remains medium because current Bab el-Mandeb transit counts are still absent; coastal control remains unresolved.

Key judgments

1. Commercial shipping through Bab el-Mandeb is likely to remain disrupted over the next 0-14 days, while a broad physical closure is unlikely. Reporting describes Houthi attacks, rerouting and a disrupted shipping classification; Suez recorded 1,228 vessel transits in September, and liner capacity averaged 753,000 teu in the first two weeks of October. The supplied assertion of simultaneous closure of Bab el-Mandeb and the Strait of Hormuz is uncorroborated and conflicts with reporting of continued Suez traffic. No current Bab el-Mandeb transit count is provided. (Confidence: medium · ASSESSED)
   • I&W: UKMTO or JMIC reports that commercial vessels have stopped transiting Bab el-Mandeb, with the halt corroborated by vessel tracking or multiple carrier notices. (0-14 days)
   • I&W: A seven-day vessel-tracking sample shows regular commercial passages through Bab el-Mandeb and carriers maintain scheduled Red Sea services. (0-14 days)
2. Freight and war-risk costs for Red Sea shipping are likely to remain elevated over the next 1-3 months. Trade reporting says premiums have increased and traders are considering Cape of Good Hope diversions for wheat, corn, barley and sugar cargoes, adding 10-14 days to voyages. Egypt reports Suez Canal losses exceeding $10 billion. These reports establish cost and routing pressure, but do not provide a current, quantified rate series for Red Sea voyages. (Confidence: medium · ASSESSED)
   • I&W: Shipowners continue to announce Cape of Good Hope diversions for Red Sea cargoes, with reported voyage extensions of 10-14 days or higher. (1-3 months)
   • I&W: At least two carriers publish regular Bab el-Mandeb sailings and insurers reduce southern Red Sea war-risk premiums across consecutive renewal periods. (1-3 months)
3. It is likely that control of Yemen's coastal approaches to Bab el-Mandeb remains unsettled. Houthi reporting claims control of the Hanish Islands, Hays and Al Khawkhah in Al-Hudaydah, and Mokha and Dhubab in Taiz; Yemeni government forces claim to have retaken territory and secured access near the strait. The accounts conflict and lack independent confirmation of current positions. (Confidence: low · ASSESSED)
   • I&W: Houthi and Yemeni government statements continue to make competing claims over named coastal positions without independent confirmation. (0-14 days)
   • I&W: Independent reporting or geolocated imagery establishes which force controls Mokha, Dhubab or access near Bab el-Mandeb. (0-14 days)
4. Operation EUNAVFOR Aspides is likely to remain short of the escort capacity needed to meet all requests over the next 1-3 months. A trade report says escort demand is rising while available assets fall short; Kaja Kallas has stated an aim to increase the fleet to 10 ships and extend the mandate to 28 February 2027, but the reporting does not confirm that the expansion has taken effect. (Confidence: medium · ASSESSED)
   • I&W: EU reporting confirms that the Aspides fleet has reached 10 ships and that escort requests are being met. (1-3 months)
   • I&W: Aspides reporting continues to describe unfilled escort requests or insufficient naval assets. (1-3 months)

Outlook & scenarios

Disruption persists, with commercial passage continuing (65%)

Likely baseline. Houthi attacks and threat declarations continue to deter some operators from Bab el-Mandeb, while commercial passage remains possible. Some sensitive cargoes divert around the Cape of Good Hope, keeping voyage times and insurance costs elevated.

Cautious return to Red Sea routes (20%)

Unlikely but plausible if reported attacks decline and shipping firms gain confidence in protection and passage. Carriers restore some scheduled Red Sea services, and insurers lower premiums gradually rather than treating the route as fully safe.

Effective suspension of Bab el-Mandeb transits (10%)

Unlikely, high impact. A further series of attacks or coercive Houthi actions prompts major carriers and insurers to suspend commercial passage through Bab el-Mandeb. Diversions around Africa become more widespread and Suez traffic faces renewed pressure.

Simultaneous closure of Bab el-Mandeb and Hormuz (5%)

Very unlikely, with very high impact. The supplied assertion of simultaneous closure is uncorroborated and conflicts with reporting of continued shipping activity. If confirmed, it would force major rerouting across both maritime corridors and intensify the reported costs to trade.

Recommendations

1. Maintain separate incident and transit assessments for Bab el-Mandeb, the Red Sea and the Strait of Hormuz. Do not combine attack totals from different waterways or reporting methodologies.
2. Before assessing Bab el-Mandeb as physically closed, require corroboration from vessel-tracking data and multiple carrier or maritime authority notices. Treat the claim of simultaneous closure of both straits as unverified unless independently confirmed.
3. Track weekly Bab el-Mandeb passages, Suez transits, carrier diversion notices and southern Red Sea war-risk premiums. Use these measures to distinguish continuing disruption from a material easing or a closure.
4. Monitor EU confirmation of the Aspides fleet size and its ability to meet escort requests. Do not treat the stated aim to reach 10 ships as an operational deployment until confirmed.
5. Include the reported 10-14 day Cape of Good Hope voyage extension in near-term assessments of cargo delays, especially for wheat, corn, barley and sugar shipments serving importers in the Horn of Africa, the Arabian Peninsula and the Red Sea littoral.

Confidence & uncertainty

Overall confidence is high for the broad finding of sustained Red Sea shipping disruption. Major-media reporting, trade reporting and Egyptian reporting converge on attack-related rerouting, higher risk costs and effects on Suez traffic. Confidence is lower on current Bab el-Mandeb transit volumes, control of specific Yemeni coastal positions and whether the proposed Aspides expansion has been implemented. The assertion of simultaneous closure of Bab el-Mandeb and Hormuz is uncorroborated and conflicts with reporting of continued shipping activity.
