Red Sea Shipping Disruption: Bab el-Mandeb Traffic Remains Low

Time window: Last 7 days · Audience: General analyst · Type: Situation report · DTG: 2026-10-27 01:14Z · Overall confidence: HIGH

BLUF

Bab el-Mandeb remained open but traffic was well below normal: JMIC recorded 58 commercial transits from 22 to 24 October, an average of about 19 a day against its stated baseline of around 61. Traffic is likely to remain disrupted over the next 14 days. Renewed Houthi-Saudi exchanges raise spillover risk, but the supplied reporting establishes neither a physical closure nor a confirmed commercial-vessel attack in the strait during this period.

Executive summary

JMIC reported 58 commercial transits through Bab el-Mandeb from 22 to 24 October, about 32% of its stated daily baseline when averaged across those three days. On 25 October, the Houthis said they launched dozens of ballistic missiles against Saudi targets, including King Khalid International Airport, King Khalid Air Base in Khamis Mushait and a Saudi Border Guard naval base in Jazan. The Saudi-led coalition reported intercepting 12 missiles and two drones, and on 26 October said it intercepted another ballistic missile directed towards Riyadh. The Houthis also claimed on 24 October to have targeted Saudi oil infrastructure, including the East-West Pipeline, an Aramco facility in Yanbu and the Rabigh refinery; Saudi Arabia had not confirmed those claims in the supplied reporting. Egypt's parliament authorised President Abdel Fattah el-Sisi on 26 October to help defend Saudi Arabia if Riyadh requests it. The reporting describes possible air-defence and aircraft support, but does not establish that Egyptian forces have deployed.

Change from previous assessment

Since the 26 October prior brief, the assessment adds JMIC's quantified report of 58 Bab el-Mandeb transits from 22 to 24 October. This strengthens the evidence for below-baseline traffic, but the single three-day window does not establish a full closure or justify raising confidence above medium. The assessment of elevated shipping risk remains, with the 25 to 26 October Houthi-Saudi exchanges and Egypt's 26 October authorisation adding current context. The prior brief's judgment on control of Mokha, Dhubab and Perim is not updated here because the supplied new reporting does not resolve those competing accounts.

Key judgments

1. Bab el-Mandeb traffic is likely to remain below normal through 10 November. JMIC reported 58 transits between 22 and 24 October, averaging about 19 per day, roughly 32% of its stated historical baseline of 61 a day. This indicates reduced traffic, not closure. Confidence is medium: the JMIC figure is specific, but it covers only three days and the supplied reporting provides no independent daily count. (Confidence: medium · ASSESSED)
   • I&W: Confirms continued disruption: JMIC daily counts remain below 30 transits for three consecutive days. (0-14 days)
   • I&W: Breaks the assessment: JMIC daily counts exceed 45 transits for three consecutive days. (0-14 days)
2. A full physical closure of Bab el-Mandeb is unlikely over the next 14 days. JMIC recorded 58 transits during 22 to 24 October, demonstrating that commercial passage continued during that reporting window. Confidence is medium: the transit report supports continued passage then, but does not establish conditions after 24 October or provide a complete daily series. (Confidence: medium · ASSESSED)
   • I&W: Breaks the assessment: JMIC reports zero Bab el-Mandeb transits for 24 hours, or a maritime advisory reports that commercial passage has been suspended. (0-14 days)
   • I&W: Confirms continued passage: JMIC reports at least 20 transits per day for three consecutive days. (0-14 days)
3. Commercial shipping in the Red Sea and Bab el-Mandeb is likely to face elevated risk over the next 14 days as Houthi-Saudi attacks continue, but the supplied reporting does not confirm a Houthi attack on a commercial vessel in the strait during this period. The 25 October reports describe attacks on Saudi territory, not on shipping. Confidence is low: the recent exchange is reported, but the connection to a future maritime attack is an inference and the supplied evidence does not document a current strike on a vessel in Bab el-Mandeb. (Confidence: low · ASSESSED)
   • I&W: Confirms the risk assessment: UKMTO issues a verified report of a commercial-vessel strike in the Red Sea or Bab el-Mandeb. (0-14 days)
   • I&W: Breaks the assessment: JMIC daily Bab el-Mandeb counts exceed 45 for three consecutive days and Saudi Arabia and the Houthis announce a halt to attacks. (0-14 days)
4. The Houthi claim of 24 October that the East-West Pipeline, crude-oil pumping stations, an Aramco facility in Yanbu and the Rabigh refinery were targeted remains unverified. Saudi Arabia had not confirmed the alleged attacks in the supplied reporting, so the claims do not establish damage or an interruption to Saudi Red Sea oil exports. Confidence is medium: major-media reports document the Houthi claims and the absence of Saudi confirmation, but do not independently verify the alleged strikes. (Confidence: medium · REPORTED)
   • I&W: Confirms the claims: Saudi authorities confirm damage or an operational interruption at the East-West Pipeline, Yanbu Aramco facility or Rabigh refinery. (0-14 days)
   • I&W: Weakens the claims: Saudi authorities report no damage and pipeline or facility operations continue without interruption. (0-14 days)
5. Egypt is likely to keep its newly authorised support to Saudi Arabia defensive over the next 30 days, with no evidence in the supplied reporting of Egyptian forces deploying to Yemen. On 26 October, Egypt's House of Representatives authorised President Abdel Fattah el-Sisi to help defend Saudi Arabia if Riyadh requests it. An unnamed regional official said the support would include air-defence systems and aircraft, while el-Sisi said Egypt would not attack Yemen. Confidence is medium: the authorisation and public statement are reported, but the prospective deployment details rely on a single unnamed official. (Confidence: medium · ASSESSED)
   • I&W: Confirms implementation of defensive support: Egypt's government announces that air-defence systems or aircraft have been deployed to Saudi Arabia. (0-30 days)
   • I&W: Breaks the assessment of a defensive-only role: Egypt announces or deploys ground forces to Yemen. (0-30 days)

Outlook & scenarios

Protracted disruption without closure (65%)

The most likely course is continued below-baseline traffic through Bab el-Mandeb into early November, while Houthi-Saudi exchanges continue. The strait remains open, but the 22 to 24 October transit count remains the latest quantitative indicator in the supplied reporting.

Maritime spillover (20%)

An unlikely but plausible escalation is a Houthi attack on a commercial vessel near Bab el-Mandeb, or independently confirmed damage to the East-West Pipeline, the Yanbu Aramco facility or the Rabigh refinery. Either development would extend the current security pressure beyond attacks on Saudi territory.

Limited diplomatic restraint (10%)

Saudi, Turkish and Pakistani representatives meet Iranian counterparts in Tehran, and follow-up contact reduces the pace of Houthi-Saudi attacks. Bab el-Mandeb traffic begins to recover, although the supplied reporting does not establish that the scheduled meeting produced an agreement.

Temporary physical interruption (5%)

Low-probability, high-impact wildcard: Houthi action deters or prevents commercial passage through Bab el-Mandeb for several days. JMIC reports zero transits or maritime advisories announce a suspension of commercial passage.

Recommendations

1. Track JMIC's Bab el-Mandeb transit count daily against its stated baseline of about 61 vessels per day. Treat fewer than 30 transits per day for three consecutive days as a warning of worsening disruption, and more than 45 per day for three consecutive days as evidence of recovery.
2. Before attributing any commercial-vessel incident to the Houthis, seek a verified UKMTO report or confirmation from the vessel operator or flag state. Confirm the incident's exact location and distinguish Bab el-Mandeb and Red Sea events from incidents in the Strait of Hormuz or Gulf of Oman.
3. Check Saudi government statements and operational reporting for the East-West Pipeline, the Yanbu Aramco facility and the Rabigh refinery. Do not treat the 24 October Houthi claim as confirmed damage or disrupted exports without corroboration.
4. Monitor Egyptian government announcements for actual deployment to Saudi Arabia. Keep parliamentary authorisation, announced defensive support and movement of forces as separate indicators; treat any Egyptian ground deployment to Yemen as a change in the assessed scope.

Confidence & uncertainty

Overall confidence is high for the broad situation: JMIC provides a quantified Bab el-Mandeb transit report, while major-media and wire reporting describe the 25 to 26 October Saudi-Houthi exchanges and Egypt's 26 October parliamentary authorisation. The transit figure is repeated across outlets but is not independently counted in the supplied material. Confidence is lower for the forward-looking risk estimate and the alleged Saudi infrastructure strikes: the former is an inference from attacks on Saudi territory, and the latter remains unconfirmed by Saudi Arabia.
