Hormuz Shipping Risk Remains Severe as Houthi-Saudi Fire Intensifies

Bottom Line

The Strait of Hormuz remains the highest-priority near-term risk. UKMTO and ADNOC report fresh vessel incidents, JMIC reports single-digit to low-double-digit daily transits and about 162 ships anchored near Fujairah and Khor Fakkan, while no source establishes a complete closure. Commercial traffic is likely to remain below the 85-transit IMF PortWatch benchmark during each of the next three 24-hour periods, but confidence is low because no independently validated current all-vessel count is supplied.

Houthi-Saudi exchanges intensified on 11 November, with Houthi claims of missile and drone attacks on Riyadh and Yanbu and Saudi-led coalition claims of interceptions. The reporting does not verify successful strikes, a general Houthi closure of Bab al-Mandab or a new merchant-vessel hit. The Abu Dhabi talks involving Ukraine, Russia and the US resumed without a reported ceasefire.

Key Developments

• Hormuz: UKMTO reported an unidentified projectile strike on a tanker near Lima, Oman, on 10 November. ADNOC confirmed damage to one of its vessels in UAE waters. JMIC reported five attacks off Oman's Musandam coast between 1 and 5 November, further incidents on 7 November and about 162 ships anchored near Fujairah and Khor Fakkan on 8 November.
• Energy: Brent futures were reported at roughly $92 to $93 on 11 November, not $108. QatarEnergy's force majeure remains in effect through year-end. Orlen initiated termination of one Qatar supply contract, which remains in force for a further 60 days, and retains a second contract.
• Yemen and Saudi Arabia: The Houthis claimed three cruise missiles aimed at King Khalid International Airport in Riyadh and a drone attack on Pumping Station No. 11 near Yanbu. The Saudi-led coalition reported interceptions. Somali piracy remains a separate Gulf of Aden threat, with 22 seafarers reportedly held aboard the Tanzanian-flagged MT Asana.
• Ukraine: Ukraine's General Staff recorded 156 combat engagements on 9 November. Russian strikes continued, while Ukraine reported attacks on the Kirishi refinery and Ust-Luga port. Attribution and damage at Ust-Luga remain disputed.
• Taiwan Strait: Taiwanese officials reported more than 100 PLA Navy and China Coast Guard vessels at sea on 3 November, along with Western Pacific area-denial drills involving the Liaoning carrier group. Taiwan recorded four PLA aircraft sorties, seven PLA Navy vessels and three official ships in the 24 hours to 11 November.
• Gaza: Gaza authorities reported that heavy rain damaged or submerged 70,000 tents affecting about 350,000 people. Civil Defence answered 218 of more than 2,000 distress calls. Medical sources reported further Israeli strikes and deaths in Gaza City.

Analysis

The assessment is consistent with the previous briefing. Hormuz remains the leading maritime and energy risk, and a full closure remains unverified. The new Houthi-Saudi exchanges add regional conflict pressure but do not alter the assessment that Bab al-Mandab has not been shown to be generally closed. Hormuz and Bab al-Mandab require separate tracking because the current evidence supports severe disruption in one chokepoint and only selective restrictions in the other.

The operational effects are better established than attribution. UKMTO, JMIC and ADNOC corroborate vessel damage and severe maritime risk, but the identity of the attacker, the role of mines and the relationship between separate incidents remain unresolved. Party claims from Iran, the Houthis, Saudi Arabia, Russia, Ukraine and Gaza authorities provide useful indications of activity but do not independently establish damage, casualty totals or battlefield effects.

The energy consequences are direct even without a formal closure. Qatar LNG deliveries face contractual disruption through year-end, Gulf crude and LNG shipments lack an equivalent alternative route, and tanker operators face anchorage delays and elevated security exposure. Brent at roughly $92 to $93 shows that price levels alone do not measure the operational risk. Vessel movements, cargo flows and infrastructure damage are separate indicators.

The Ukraine talks have not changed the near-term battlefield outlook. Positive descriptions from Volodymyr Zelenskyy, Marco Rubio and Jared Kushner contrast with Sergey Lavrov's rejection of a truce and the unresolved dispute over Donetsk territory. Russian strikes on Ukrainian energy infrastructure are likely to continue, while Ukrainian attacks on Russian energy and export facilities are also likely. Confidence is moderate because the engagement count and strike reports are supported by official and major-media reporting, but several damage and attribution claims remain contested.

The broad PLA activity around Taiwan is consistent with area-denial training and strategic signalling, but the supplied evidence does not prove one coordinated operation rehearsing Taiwan's isolation. Taiwanese official reporting is credible for what Taiwan detected and assessed, but ship tracking does not establish command relationships or mission. The absence of an attack order or invasion-force assembly supports an unlikely near-term attack judgement, with low confidence because the source set is limited.

The source base is mixed. Specialist maritime notices and major-media reporting provide the strongest support for vessel incidents, ship congestion, the Spanish strike, the Abu Dhabi talks and the Ukraine strike tempo. Official belligerent claims, local casualty accounts, blogs and social-media reports are weaker for attribution, precise casualty totals, territorial control and clandestine activity. Assessments relying on those weaker streams are identified with lower confidence.

Indicators & Warnings

• Iranian closure measures: Watch for an Iranian government, IRGC or port notice denying passage, new permit rules applied across multiple flags, or three consecutive 24-hour periods with zero independently verified commercial transits. Horizon: 24 hours to 14 days.
• Hormuz recovery: More than 85 commercial transits in two consecutive 24-hour periods, together with ships departing Fujairah and Khor Fakkan and renewed tanker sailings for Qatar, Saudi Arabia and the UAE, would weaken the severe-disruption assessment. Horizon: 24 to 72 hours.
• Further merchant attack: A new UKMTO or JMIC report of a tanker strike, mine incident, boarding or fire near Hormuz, followed by physical evidence or independent corroboration, would confirm continued escalation. A verified hit at Bab al-Mandab would break the current assessment that maritime spillover remains unconfirmed. Horizon: 24 hours to 14 days.
• US-Iran escalation: US carrier or bomber repositioning, evacuation notices, new target-related statements or an announced strike would raise the escalation forecast. A joint US-Iran, Qatari or Pakistani statement containing reopening terms and a monitoring mechanism would lower it. Horizon: 72 hours to 14 days.
• Houthi maritime expansion: A verified hit on a commercial vessel, a Houthi order covering non-Saudi or non-Israeli shipping, or a sustained fall in independently counted Bab al-Mandab transits would indicate geographic expansion. Horizon: 72 hours to 14 days.
• Ukraine negotiations: A joint Abu Dhabi communiqué, prisoner exchange or temporary ceasefire would indicate movement towards containment. Continued Russian rejection of a truce, renewed strikes on Ukrainian energy infrastructure or intensified fighting near Pokrovsk and Kostiantynivka would confirm continuation of the current war pattern. Horizon: 72 hours to 14 days.
• Taiwan exercise transition: A Chinese exercise announcement, exclusion zones around Taiwan, simultaneous carrier and amphibious-force convergence, mobilisation orders or sustained air and maritime activity on several axes would support the isolation-exercise hypothesis. Horizon: 7 to 30 days.
• Gaza shelter deterioration: Additional verified strikes on Gaza City, renewed flooding, further loss of sewage or drainage capacity, or failure of shelter and fuel deliveries would confirm persistent severe conditions. Horizon: 24 hours to 30 days.

Alternatives

• Selective Iranian restriction continues without formal Hormuz closure, likely over the next 14 days. This best fits the combination of vessel attacks, reduced movement, Iranian reopening conditions and the absence of a verified blanket denial of passage. Confidence is low to moderate.
• Formal or de facto Hormuz closure follows another attack, unlikely over the next 14 days but high impact. A further tanker attack, mine incident, US-Iran strike or insurer withdrawal could turn selective disruption into a broad commercial stoppage. The scenario remains less likely because reported flows have not reached zero and no closure order has been supplied. Confidence is low.
• US-Iran diplomacy produces a temporary maritime pause, unlikely over the next 14 days. Qatar and Pakistan are reported to have mediated contacts, but Tehran denies substantive talks and no mutually accepted reopening terms or timetable has emerged. Confidence is low.
• Houthi-Saudi exchanges remain geographically bounded, likely over the next 14 days. Current Houthi claims focus on Saudi military and energy targets, while no current merchant-vessel strike at Bab al-Mandab is independently verified. Confidence is moderate for continued Saudi-focused exchanges and low for the absence of a merchant attack.
• Abu Dhabi talks produce a limited ceasefire despite unresolved territorial issues, unlikely in the next 14 days. Positive descriptions of the talks do not overcome Russia's rejection of a truce or the unresolved Donetsk dispute. A prisoner exchange or local pause is more plausible than a comprehensive settlement, but neither is reported.

Outlook

Commercial traffic through Hormuz is likely to remain below the 85-transit IMF PortWatch benchmark during each of the next three 24-hour periods, at about 70 per cent, with low confidence. A formal Iranian closure remains unlikely over the next 14 days, at about 15 per cent, with moderate confidence. Selective restriction through permits, inspections or treatment by flag, cargo or operator is likely, at about 60 per cent, with low confidence. A de facto commercial closure caused by vessel withdrawal or insurer refusal is unlikely, at about 20 per cent, with low confidence.

Further attacks on commercial shipping near Hormuz are likely over the next 14 days, at about 70 per cent, with moderate confidence. A new US kinetic strike on Iran is unlikely during the next 72 hours, at about 20 per cent, with moderate confidence, but is a roughly even chance by 24 November. Houthi-Saudi exchanges are likely to continue through 24 November, at about 65 per cent, with moderate confidence, while a confirmed Houthi attack on a merchant vessel in the Red Sea or Bab al-Mandab is unlikely, at about 30 per cent, with low confidence.

Russian strikes on Ukrainian energy and civilian infrastructure are likely by 24 November, at about 70 per cent, with moderate confidence. An agreed ceasefire in the next 14 days is unlikely. Continued broad PLA activity around Taiwan is likely over the next month, but a PLA attack within one to three months is unlikely, with low confidence. Gaza's shelter emergency is very likely to remain severe through February 2027, with moderate confidence.
