BLUF

Houthi drone and missile activity against Red Sea shipping is very likely to persist, with a declared ban on Israel‑linked vessels and fresh thermal activity around Bab el‑Mandeb. Trade is adapting through alternative routes, adding costs and shifting flows.

Executive summary

Open sources continue to show an active Houthi threat to commercial shipping in the Red Sea, including a stated ban on Israel‑linked vessels and repeated use of drones and missiles. Satellite thermal detections near Bab el‑Mandeb in the last 48 hours are consistent with ongoing kinetic activity in the maritime approaches. Economic signals point to sustained disruption, with higher import costs, unusual carrier profitability and depressed Suez and Eilat performance reported in early 2026. Regional actors, notably India, are promoting alternative corridors to limit exposure while Red Sea risks endure.

Change from previous assessment

Since the 23 June brief, fresh satellite thermal detections near Bab el‑Mandeb point to ongoing kinetic activity in the maritime approaches, and reporting reiterates the Houthis’ resumed missile attacks and declared ban on Israel‑linked vessels. Economic reporting continues to describe elevated costs and altered trade flows, with India’s Eastern Maritime Corridor highlighted as an alternative amid Red Sea risk. Confidence in the persistence of the Houthi threat remains high; no new evidence was identified on Somaliland‑related triggers, so that thread is not advanced in this update.

Key judgments

1. Houthi risk to commercial shipping in the Red Sea is very likely to persist for at least the next 1-3 months, with continued drone and missile attacks and a declared ban on Israel‑linked vessels; recent thermal detections at Bab el‑Mandeb indicate ongoing kinetic activity. (Confidence: high · ASSESSED)

• I&W: Official Houthi claim of a strike on a named commercial vessel in the Red Sea, corroborated by operator reporting or AIS data loss near the incident coordinates. (0-14 days)
• I&W: Sustained 30-day lull in Houthi attack claims paired with absence of VIIRS thermal anomalies within 30 nm of the Bab el‑Mandeb traffic separation scheme. (1-3 months)

2. Iran is likely enabling and encouraging the Houthi maritime pressure campaign in the Red Sea, sustaining capability and intent to target vessels over long ranges. (Confidence: medium · ASSESSED)

• I&W: Publicly verifiable interdiction or sanctions listing tying IRGC naval personnel or equipment shipments to Houthi maritime operations. (1-3 months)
• I&W: Authoritative Iranian and Houthi statements disavowing operational coordination, followed by a sustained reduction in Red Sea attack tempo. (1-3 months)

3. Red Sea‑linked disruption is likely to continue producing material economic effects, including higher import costs, outsized carrier profitability, depressed Suez Canal transits, and the near‑shutdown of Israel’s Port of Eilat by early 2026. (Confidence: medium · ASSESSED)

• I&W: Next Suez Canal Authority monthly transit bulletin shows totals at least 40 percent below comparable pre‑2026 months. (1-3 months)
• I&W: Major carriers remove or markedly cut Red Sea war‑risk and disruption surcharges in quarterly tariff updates. (1-3 months)

4. Regional actors, notably India, are likely to keep diversifying away from Red Sea lanes while risk persists, including increased use of the Eastern Maritime Corridor that is promoted as a viable route and asserted to save about 24 days versus Suez. (Confidence: medium · ASSESSED)

• I&W: Public scheduling or announcements of additional EMC sailings by Indian or Russian maritime authorities or major lines. (1-3 months)
• I&W: Official Indian guidance de‑emphasises EMC in favour of routine Suez usage for the same trades. (1-3 months)

Outlook & scenarios

Steady‑state Houthi harassment in the southern Red Sea and Bab el‑Mandeb (60%)

Houthi forces continue a sustained pattern of drone and missile harassment, prioritising vessels they assess as Israel‑linked and striking near Bab el‑Mandeb. Periodic thermal detections and intermittent damage reports keep war‑risk surcharges elevated and transit plans adaptive.

Escalation enabled by Iran extends target set and range (30%)

Iranian enabling sustains Houthi operations and encourages longer‑range maritime attacks. Engagements expand beyond the immediate Red Sea approaches, raising risk to a wider set of flags and operators and complicating naval risk‑mitigation.

Tactical de‑escalation as Tehran eases pressure at Bab el‑Mandeb (20%)

Tehran reduces use of Bab el‑Mandeb as a pressure lever, prompting a lull in Houthi maritime attacks and narrowing of the target set. War‑risk pricing softens, but operators maintain diversified routing until trend stability is clear.

Recommendations

1. Stand up a daily Red Sea watch using NASA FIRMS VIIRS thermal alerts for the Bab el‑Mandeb approaches, fused with AIS to flag coincident maritime activity for rapid escalation to operators.
2. Maintain a structured watchlist of Houthi communiqués and declared bans on Israel‑linked beneficial owners to inform routing, chartering, and risk scoring.
3. Task collection to track indicators of Iranian enabling of Houthi maritime operations, including any verifiable interdictions or public sanctions actions linking IRGC personnel or logistics to Yemen.
4. Advise clients moving India‑bound cargoes to model Eastern Maritime Corridor routings alongside Suez, using the asserted 24‑day time saving to compare cost, schedule, and insurance outcomes.
5. Engage with underwriters to monitor changes in Red Sea war‑risk premiums and terms, and pre‑clear contingency routings that minimise exposure near Bab el‑Mandeb.

Confidence & uncertainty

Multiple independent and reliable sources report ongoing Houthi targeting of Red Sea shipping with drones and missiles, and recent Bab el‑Mandeb thermal detections provide timely geospatial corroboration of kinetic activity. Economic effects tied to the Red Sea crisis are reported across separate outlets. Assertions about Iranian enabling of the Houthi campaign are supported by consistent local and regional reporting and analysis, though elements rely on single‑source or lower‑reliability items, so confidence on that mechanism is lower than for the persistence of the Houthi threat itself. Overall confidence is assessed as high given the corroboration of the core threat picture and observable indicators, with uncertainty concentrated on the scale of Iranian operational involvement and the exact magnitude of longer‑term economic impacts.

Alternative analysis (red cell)

While attacks and thermal detections indicate episodic risk, the package shows heavy reliance on a single reporting origin for many core claims, ambiguous thermal evidence, and several low‑admiralty or contradicted economic assertions. A sober alternative assessment is that the threat is intermittent and localized, Iranian direction is unproven in open reporting, and the scale/timing of economic diversion and losses remain uncertain pending multi‑source ISR, forensics, AIS/throughput data, and corroborated HUMINT/SIGINT.
