Red Sea Shipping Disruption: Selective Recovery, Persistent Risk

Time window: Last 7 days · Audience: General analyst · Type: Situation report · DTG: 2026-08-24 11:24Z · Overall confidence: MEDIUM

BLUF

Commercial shipping risk in the southern Red Sea and Bab-el-Mandeb is very likely to remain elevated over the next 0-14 days. Large container ships are returning to the Suez Canal, but continued port closure, vessel damage and rerouting indicate selective recovery rather than restored normal service.

Executive summary

The latest reporting shows a mixed picture. Al-Mokha Port remains closed, a cargo ship off Yemen was declared a constructive total loss after projectile strikes, and UKMTO continues to advise caution near Al Mukha. At the same time, Bangkok Maersk transited the Suez Canal on 23 August and large container ships are returning to the waterway. Houthi pressure on Saudi-linked shipping remains the main immediate risk, although reporting does not establish Houthi control of the Bab-el-Mandeb.

Change from previous assessment

The assessment of elevated risk and selective disruption is broadly unchanged from the prior brief. The 23 August Bangkok Maersk transit and the reported return of large container ships strengthen the judgement that Suez recovery is partial rather than a full reopening. Continued northern routing for Saudi crude reinforces the persistence of risk mitigation. No new corroboration resolves attribution of the reported attacks or the competing claims about Houthi reach towards the Bab-el-Mandeb. The prior Somali piracy judgement is retired in this brief because the current approved claims provide no updated piracy reporting.

Key judgments

1. It is very likely that commercial shipping risk in the southern Red Sea, the Bab-el-Mandeb and waters near Al Mukha will remain elevated over the next 0-14 days. Al-Mokha Port remains completely closed after more than 25 missile impacts and fires, UKMTO advises vessels near Al Mukha to transit with caution, and a cargo ship off Yemen was declared a constructive total loss after being struck by multiple unknown projectiles. NASA recorded seven thermal detections in the Bab-el-Mandeb on 23 August, although none was high confidence and the detections do not establish cause. Hans Grundberg has warned that Houthi attacks threaten global trade. Confidence is medium because official and multilateral reporting supports the broad risk picture, while attribution of the cargo-ship incident and the cause of the thermal detections remain unresolved. (Confidence: medium · ASSESSED)

• I&W: Confirm: UKMTO reports another projectile, drone or suspicious-activity incident within 50 nautical miles of Al Mukha. (0-14 days)
• I&W: Break: Al-Mokha Port reopens to commercial traffic and UKMTO withdraws its cautionary routing advice for vessels near Al Mukha. (0-14 days)

2. It is likely that disruption will remain selective rather than become a sustained closure of all commercial traffic through the Bab-el-Mandeb over the next 1-3 months. Bangkok Maersk transited the Suez Canal on 23 August, large container ships are returning to the waterway, and shipowners including Sinokor Group are moving Saudi Arabian crude via the safer northern Red Sea route. Commercial traffic nevertheless remains subdued, and the recovery of Suez Canal traffic remains partial. Confidence is medium because the current container-ship movements are concrete, while several traffic and recovery comparisons are undated or based on older reporting. (Confidence: medium · ASSESSED)

• I&W: Confirm: at least three additional large container ships from major carriers complete Suez Canal transits while Al-Mokha Port remains closed. (0-14 days)
• I&W: Break: two or more major container carriers suspend their returning Suez services and vessel-tracking data shows a sustained fall in traffic through the Bab-el-Mandeb. (0-14 days)

3. It is likely that the Houthis will continue using missiles and drones to pressure Saudi-linked shipping and targets on Yemen's western coast over the next 0-14 days, but it is very unlikely that available reporting demonstrates Houthi physical control of the Bab-el-Mandeb or an imminent seizure of the strait. The Houthis announced a blockade against Saudi Arabia on 20 July, claimed responsibility for strikes on Saudi tankers, and on 17 August claimed to have hit a Saudi military ship and four escort vessels. Separate reporting states that the Houthis use long-range firepower to threaten commercial ships. Claims that the group plans to seize the strait conflict with reporting that it has not reached the Bab-el-Mandeb. Confidence is low because several operational accounts are based on Houthi statements, unknown-source reporting or single-source analysis, and the reported tanker attacks and 17 August incident are not independently reconciled. (Confidence: low · ASSESSED)

• I&W: Confirm: UKMTO or a national maritime authority independently reports a missile or drone attack on a named Saudi-linked commercial vessel in the Red Sea. (0-14 days)
• I&W: Break: Yemeni government forces or independent vessel tracking verifies Houthi units reaching the Bab-el-Mandeb or establishing positions on its immediate coastline. (0-14 days)

4. It is likely that carriers and Saudi exporters will continue using costly risk-mitigation measures over the next 1-3 months despite a partial return of Suez traffic. Shipowners are helping Saudi Arabian crude exit the Red Sea through the northern route, Saudi Aramco has increased exports from Sidi Kerir in the Mediterranean, and reporting attributes increases in marine insurance costs of as much as 20 times to Houthi attacks. Confidence is medium because the rerouting measures are supported by major-media and trade reporting, but the insurance estimate is undated and the scale of current cost relief is unclear. (Confidence: medium · ASSESSED)

• I&W: Confirm: shipowners continue routing Saudi crude through the northern Red Sea or Sidi Kerir while insurers retain elevated war-risk premiums. (0-14 days)
• I&W: Break: Maersk and CMA CGM announce unrestricted Suez services and reported marine insurance premiums return towards pre-disruption levels. (1-3 months)

Outlook & scenarios

Selective disruption with gradual Suez expansion (55%)

It is likely that large container carriers will expand Suez use gradually while tankers and Saudi-linked cargo continue to favour northern Red Sea routes. Al-Mokha Port remains closed, and vessel operators retain enhanced routing and insurance precautions.

Renewed attacks reverse the recent recovery (25%)

It is unlikely that further Houthi missile or drone attacks on Saudi-linked shipping will force several major carriers to suspend Suez services again. Traffic through the Bab-el-Mandeb would fall, with additional cargo routed around Africa or through northern Red Sea alternatives.

Houthi move towards the Bab-el-Mandeb (10%)

It is very unlikely, but high impact, that Houthi forces move towards the Bab-el-Mandeb and establish positions near the strait. Such a development would sharply increase the risk of a wider maritime closure and pressure carriers to abandon returning Suez services.

Sustained de-escalation and broader normalisation (20%)

It is unlikely that security conditions improve sufficiently for major carriers to restore broad Suez operations within 1-3 months. This scenario requires sustained absence of attacks, reopening of Al-Mokha Port and continued growth in large-vessel transits.

Recommendations

1. Maintain a 24-hour watch on UKMTO notices near Al Mukha, with immediate reassessment after any projectile, drone or suspicious-activity report.
2. Separate container-ship, tanker and Saudi-linked traffic in daily tracking. Do not treat a small number of Suez transits as evidence of restored normal service.
3. Require independent corroboration before attributing the cargo-ship loss, thermal detections or reported attacks to the Houthis. Treat Houthi statements as indicators of intent rather than proof of operational effect.
4. Track Al-Mokha Port status, major-carrier sailing schedules, northern Red Sea crude movements and marine insurance premiums as a single disruption dashboard.
5. Prepare route and cost assessments that distinguish Suez transits, northern Red Sea movements and diversions around Africa. Update the assessment when two or more major carriers change service patterns.
6. Include the Bab-el-Mandab fishing community and port workers in the operating picture, since military activity is already restricting fishing movements and commercial access.

Confidence & uncertainty

Overall confidence is medium. Official and multilateral reporting supports the core assessment of elevated maritime risk, while major-media and trade reporting corroborate the Suez transits, port closure and rerouting measures. Confidence is lower on Houthi operational attribution, the interpretation of NASA thermal detections and the timing and character of reported attacks. Several traffic, insurance and blockade claims are undated, contested or based on single-source reporting.
