Red Sea shipping disruption: Houthi threat persists as Hormuz reopening starts to shift flows back toward Suez

BLUF

Houthi threats to commercial shipping at Bab el Mandeb remain active despite EU naval protection, while early reopenings at Hormuz are likely to raise Red Sea exposure as Gulf cargoes resume Suez-bound routes. Shipping economics remain strained by elevated war-risk premiums and prior Suez revenue losses.

Executive summary

Evidence from 2024 shows the Houthis using missiles and drones against merchant shipping and damaging subsea cables in the Red Sea, while the EU’s operation Aspides and additional European deployments provide protection without removing the threat. In parallel, a memorandum-driven reopening at Hormuz is under way, with laden tankers and an LNG carrier transiting and formal advisories declaring the strait open. Industry leaders remain cautious due to mines and ongoing clearance operations, so resumption via Suez is likely to be gradual but will still increase exposure at Bab el Mandeb as volumes return. War-risk premiums and earlier Suez revenue declines keep costs high, and Yemen’s internal constraints, including the detention of UN staff and UK travel warnings, complicate diplomatic de‑escalation.

Change from previous assessment

New reporting confirms initial laden tanker and LNG passages through the Strait of Hormuz and a formal advisory declaring the strait open, while industry leaders signal continued caution due to mines and clearance timelines. European naval protection remains active, with Germany moving additional assets toward the Red Sea. These developments raise the assessed likelihood that Suez‑bound traffic will increase over the next 1-3 months, incrementally elevating exposure at Bab el Mandeb, while our judgment on persistent Houthi threat remains unchanged. Initial assessment of subsea cable vulnerability is retained as a live risk.

Key judgments

1. Houthi threats to commercial shipping in the Red Sea and Bab el Mandeb are likely to persist in the near term, given the group’s demonstrated use of missiles and drones against merchant vessels in 2024 and its June 2023 declaration banning Israeli‑linked navigation. (Confidence: medium · ASSESSED)

• I&W: Credible reporting of new Houthi‑claimed missile or drone attacks on named merchant vessels transiting Bab el Mandeb. (0-14 days)
• I&W: Thirty consecutive days without Houthi‑claimed or independently reported attacks or attempted attacks on Red Sea shipping. (1-3 months)

2. Naval protection efforts, including the EU’s operation Aspides and Germany’s deployment of Fulda and Mosel toward the Red Sea, are likely to constrain but not eliminate successful Houthi attacks over the next one to three months. (Confidence: medium · ASSESSED)

• I&W: EU or German navy reports of intercepts or engagements against Red Sea threats, alongside continued merchant traffic under escort. (0-14 days)
• I&W: Public suspension or drawdown of EU Aspides tasking in the Red Sea. (1-3 months)

3. Hormuz reopening and initial tanker movements are very likely to increase Gulf cargo volumes bound for Suez over the next one to three months, raising exposure at Bab el Mandeb even as mine threats and industry caution delay full resumption. (Confidence: medium · ASSESSED)

• I&W: Sustained reporting of additional laden VLCC and LNG transits exiting Hormuz en route to the Suez corridor. (0-14 days)
• I&W: Leading carriers publicly maintain suspension of Hormuz‑to‑Suez routings and cite unresolved mine‑clearance in the central TSS. (1-3 months)

4. Red Sea subsea communications infrastructure is likely to face further disruption risk, as shown by February, March 2024 damage to multiple cables that cut connectivity along the route. (Confidence: medium · ASSESSED)

• I&W: Further operator reports of fibre breaks on Red Sea cable segments affecting Europe, Asia links. (1-3 months)
• I&W: Operators confirm repairs completed and no new Red Sea cable incidents for sixty days. (1-3 months)

5. It is reported that Houthi attacks cut Suez Canal revenues by 40-50 percent and drove sharp increases in war‑risk premiums, which has entrenched higher costs and sustained routing caution for Red Sea transits. (Confidence: high · REPORTED)

• I&W: Insurers continue quoting elevated war‑risk additional premiums for Red Sea/Suez transits. (0-14 days)
• I&W: Market bulletins announce material reductions in Red Sea/Suez war‑risk premiums. (1-3 months)

6. Domestic constraints in Yemen, including the detention of 73 UN personnel and the UK’s blanket warning against all travel, are very likely to complicate diplomatic efforts to moderate maritime threats off Yemen’s coast. (Confidence: high · ASSESSED)

• I&W: No verified progress on the release of detained UN personnel in Yemen. (0-14 days)
• I&W: Verified release of detained UN personnel and initiation of formal discussions on maritime security with the UN Special Envoy. (1-3 months)

Outlook & scenarios

Managed risk with continued harassment (50%)

EU Aspides and partner deployments reduce the Houthi hit rate but do not end attempts. Major lines gradually increase Suez‑bound sailings as Hormuz reopens, accepting higher security costs and scheduling buffers. War‑risk premiums ease modestly but remain above pre‑crisis levels, and operators keep heightened watch and routing constraints around Bab el Mandeb.

High‑impact maritime attack triggers renewed rerouting (30%)

A successful Houthi strike severely damages or sinks a high‑capacity tanker or cargo vessel near Bab el Mandeb, or causes a mass‑casualty event. Major carriers reinstate Cape of Good Hope diversions en masse, Suez revenues remain depressed, and insurers lift war‑risk premiums further for Red Sea transits.

Communications degradation complicates maritime safety (20%)

Further damage to Red Sea subsea cables degrades connectivity for shipping along the route, hindering coordination, increasing AIS and comms outages and prompting some operators to slow‑roll returns via Suez despite progress at Hormuz.

Recommendations

1. Maintain a daily watch on Joint Maritime Information Center advisories and industry statements to track the cadence of Hormuz reopenings and any security guidance affecting Suez‑bound flows.
2. Task a focused review of carrier notices, especially from A.P. Moller‑Maersk and INTERTANKO members, to determine resumption thresholds and route‑specific risk tolerances for Red Sea transit.
3. Update exposure mapping for voyages with Israeli ownership, management, cargo, or destination links, and flag those transits for enhanced routing and security review given the Houthi ban on Israeli maritime navigation.
4. Integrate subsea cable risk into Red Sea voyage planning by monitoring operator reports for fibre breaks and planning communications contingencies for periods of degraded C2 along the corridor.
5. Advise operators and partners to retain Cape of Good Hope contingencies and additional bunkering plans until mine‑clearance milestones in the central TSS and consistent escorted passage windows are evidenced.
6. Track war‑risk premium quotes for Red Sea and Suez passages and provide weekly analytics on total voyage cost differentials versus Cape routings to inform routing decisions.
7. Engage humanitarian and diplomatic reporting channels on the status of detained UN personnel and access constraints in Yemen, assessing implications for any de‑escalation talks tied to maritime security.

Confidence & uncertainty

Overall confidence is medium. Many underlying reports on Houthi attacks, cable damage and Suez revenue impacts are high‑confidence and well‑sourced, but the most recent operational picture relies on extrapolating from earlier incidents and on industry caution amid ongoing mine threats at Hormuz. There are timeline inconsistencies in the historical onset of Houthi‑driven rerouting and mixed signals on the pace of Hormuz normalisation, which temper confidence in the speed of Red Sea exposure increases. Reporting on Yemen’s internal constraints and UN staff detentions is reliable, supporting high‑confidence judgments about diplomatic friction.

Alternative analysis (red cell)

The available reporting documents episodic attacks, isolated transits, and declaratory statements rather than a coherent, sustained campaign or clear operational effects. Naval deployments and diplomatic actions cited are announcements or early movements without demonstrated deterrent or facilitative outcomes. Given unresolved contradictions in the record and the lack of trend/forensic data, alternate inferences — including episodic violence that may not persist, limited naval impact, and detentions prompting intensified diplomacy — remain plausible.
