Hormuz traffic remains impaired without closure; IRGC Bahrain radar claim unverified

Bottom Line

Reporting cutoff: 14 November 2026, 0129 UTC.

Among the Middle East developments covered, the Strait of Hormuz poses the highest probability of disruption to crude and LNG shipping over the next 72 hours. JMIC counted approximately 211 commercial vessels at named anchorages east of Hormuz on 12 November, while CENTCOM claimed that US forces had diverted more than 150 commercial ships and disrupted five others attempting to break what it called a blockade. These are different populations and cannot be summed or used to calculate a traffic reduction. The IRGC claim to have destroyed a US early-warning radar in Bahrain on 13 November is unverified.

A further confirmed or credibly corroborated kinetic incident involving US, Iranian or Gulf-state forces is likely over the next 14 days, with low confidence. A formal Iranian closure, defined as an official general denial of passage, remains unlikely at 10 per cent over the same period, with moderate confidence.

Key Developments

JMIC, a specialist maritime security coordination centre, reported approximately 211 commercial vessels stationary at Fujairah, Khor Fakkan, Sohar and Musandam on 12 November. This is an anchorage estimate, not a census of ships attempting to cross Hormuz.
CENTCOM, an interested official US military source, claimed that US forces had diverted more than 150 commercial ships and disrupted five others attempting to break the blockade. The supplied wording does not establish whether each vessel was physically redirected, escorted, delayed or otherwise prevented from transiting. The claim is not directly comparable with the JMIC estimate.
UKMTO recorded five reports of vessel attacks in the Hormuz area between 6 and 11 November. The supplied extracts do not identify the vessels, individual dates, precise locations, damage status or causal findings for the five reports. They therefore establish a series of maritime alerts or reports, not five independently confirmed successful attacks.
The IRGC said on 13 November that it struck and destroyed a US early-warning radar in Bahrain in retaliation for alleged US action against a telecommunications tower in Sirik, Iran. The US and Bahrain had not confirmed the attack or damage. The supplied material does not name the radar installation or give its coordinates.
Iranian reporting says ships must obtain approval before transiting Hormuz. The supplied extract does not identify the issuing Iranian authority, publish the wording of an enforceable order or record a seizure, inspection or denial of passage.
Maersk and Hapag-Lloyd have begun selectively restoring their joint ME1 service through Suez. Reported departures were scheduled from Salalah on 4 November and Tangier on 12-13 November, subject to further security-based routing decisions.

Analysis

Observed: 211 vessels were reported at anchorages and CENTCOM claimed more than 150 diversions, with five additional ships disrupted according to its statement. Assessment: these indicators are consistent with increased commercial caution and delayed or rerouted voyages, but they do not quantify total traffic or prove a closure. The supplied reporting does not distinguish how much of the anchorage count resulted from Iranian action, US military intervention, voluntary operator risk avoidance, insurer constraints or port congestion. Confidence: moderate. Implication: tanker and LNG operators face uncertain voyage times and cargo-delivery exposure over the next 72 hours, while energy-market analysts cannot derive a percentage traffic loss from these figures.

The formal-closure, selective-coercion and de facto-closure pathways remain distinct. A formal closure requires an Iranian authority to deny passage generally. Selective coercion means warnings, permits, inspections, seizures or treatment by flag, cargo or operator without a general denial. A de facto closure means operators or insurers make the strait commercially unusable without a state declaration. The evidence supports likely selective coercion at 60 per cent over 14 days, unlikely formal closure at 10 per cent, and unlikely operator-driven de facto closure at 20 per cent.

The IRGC radar claim is an escalation indicator rather than an established battlefield outcome. Iranian state-linked reporting confirms that the IRGC made the claim, but the US and Bahrain had not confirmed either the strike or damage. The IRGC Navy's separate claim that an LNG carrier struck a mine also lacks immediate UKMTO confirmation, and Iranian accounts differ on the number and type of vessels involved. The claim provides Iranian leaders with a stated retaliation narrative. The supplied reporting does not show whether Washington or Tehran has changed operational plans in response.

The 70 per cent estimate for a further kinetic incident covers one or more confirmed or credibly corroborated strikes, damaging interceptions or attacks involving US, Iranian, Bahraini, Saudi or other Gulf-state forces in the Gulf, Bahrain, Iran or adjacent waters. It excludes rhetoric, unverified claims and routine force movements. Confidence is low because the current escalation case relies heavily on official statements from interested parties and lacks independent confirmation of the most consequential incident.

Selective Suez restoration does not establish regional normalisation. For Maersk, Hapag-Lloyd and their customers, it indicates that risk tolerance differs by service and corridor. Asia-Europe container services can resume selectively while Hormuz-dependent crude, LNG and refined-product cargoes remain exposed to anchorage delays, rerouting or inspection risk. The supplied material does not establish sustained interruption to fertiliser trade.

Brent futures were quoted at 96.35 US dollars per barrel on 13 November, while EIA data placed Brent spot at 92.14 US dollars on 11 November. These observations use different instruments and dates, and neither isolates the effect of Hormuz incidents. They therefore do not validate a quantified supply loss. Energy-market analysts should treat the risk as exposure to future crude, LNG and refined-product delays rather than as evidence of an established supply interruption.

For CENTCOM and Bahraini military planners, confirmation of radar damage, a US casualty or a second Iranian strike would increase the assessed risk of a linked exchange within 72 hours. For commercial tanker and LNG operators, three consecutive 24-hour periods with no independently verified commercial transits would indicate a de facto-closure pathway, while continued verified transits would weaken it. For insurers, repeated UKMTO incident notices combined with rising JMIC anchorage counts would indicate greater exposure than a single uncorroborated claim. For US, Gulf and European policymakers, a published Iranian permit regime or general denial of passage would mark a change from contested coercion to formal state enforcement.

The source pool contains 133 supplied entries: 44 assessed as consistently reliable, 35 as usually reliable, 10 as fairly reliable, 19 as not usually reliable and 25 as untested. JMIC and UKMTO are specialist maritime reporting sources, but their products measure different phenomena. CENTCOM is a first-hand official US military source for its own claimed actions, but it is an interested party. Iranian state and IRGC reporting is first-hand for what Iranian authorities claim, not independent evidence that the claimed attacks succeeded. Houthi and Saudi statements similarly establish competing claims about attacks and interceptions, not confirmed damage. Multiple media reports may repeat the same official statement, so they should not be counted as separate independent corroboration. The overall Hormuz assessment is therefore held at moderate confidence, while the radar-damage and LNG-mine claims remain low confidence.

Indicators & Warnings

All-vessel transit cessation: The current denominator-matched baseline is unavailable. Three consecutive 24-hour periods with zero AIS-verified commercial transits, corroborated by UKMTO or JMIC, would raise the de facto-closure estimate from 20 per cent to roughly an even chance. This applies to all commercial vessels, not only commodity vessels, and would not establish a formal Iranian closure. Monitor each 24-hour period over the next 72 hours.
Commodity-vessel movement: The prior Kpler series recorded five commodity-vessel crossings on 7 November and none on 8 November, with no comparable count for 9-13 November. Fewer than 10 crossings in each of the next three 24-hour periods would confirm the retained commodity-vessel forecast. More than 10 in two successive periods would weaken it. Monitor daily over the next 72 hours.
Anchorage accumulation: JMIC's 12 November baseline was approximately 211 vessels at Fujairah, Khor Fakkan, Sohar and Musandam. Two successive estimates above 250 would support increasing operator avoidance. A fall below 100 accompanied by renewed AIS-verified transits would weaken the de facto-closure pathway. Monitor each JMIC release over the next 72 hours.
Iranian enforcement: The supplied material reports warnings that ships must obtain approval but does not identify the issuing authority or provide an enforceable notice. A published permit requirement, inspection, seizure, detention, flag-specific restriction or explicit denial from Iran's Ports and Maritime Organisation, IRGC Navy, Foreign Ministry or another named authority would raise the selective-coercion estimate. Monitor daily over the next seven days.
Bahrain radar claim: The supplied material does not name the installation or provide coordinates. Commercial satellite imagery covering Bahrain from 13-15 November, US or Bahraini confirmation, visible blast or structural damage, emergency repair activity, or a US casualty or equipment-loss report would test the claim. Confirmation of an attack, physical damage and US ownership are separate tests. Assess within 72 hours.
Further kinetic exchange: CENTCOM, Bahrain, Iranian official statements, UKMTO and vessel operators should be checked for a confirmed missile, drone, aircraft or naval attack, a damaging interception or casualties involving US, Iranian, Bahraini, Saudi or other Gulf-state forces. A confirmed event would validate the defined exchange forecast. Rhetoric without independent corroboration would weaken it. Monitor continuously for 72 hours.
Diplomatic de-escalation: Iran reportedly transmitted a seven-condition proposal through Qatari mediators, while Donald Trump rejected the need for a deal. A named Qatar-US-Iran meeting, verified acceptance of a proposal, suspension of public preconditions, Iranian maritime stand-down instructions or withdrawal of US force-protection notices would reduce the probability of further kinetic action. Monitor daily over 14 days.
Adjacent corridor response: Cancellation of restored ME1 sailings, a confirmed Houthi attack on a merchant vessel in Bab el-Mandab, or sustained new insurance and routing restrictions would indicate that risk is spreading beyond Hormuz. Continued ME1 operation without a confirmed Red Sea merchant attack would support a corridor-specific assessment. Monitor carrier schedules, UKMTO notices and insurer reporting over seven days.

Alternatives

These scenarios are mutually exclusive end states at 14 days.

No credibly corroborated additional kinetic incident, with selective coercion and partial commercial access continuing, roughly even chance at 40 per cent. The radar claim and other high-impact incidents remain unverified, while US-protected movement and the absence of a general denial-of-passage order preserve partial access. The radar claim could be exaggerated or intended mainly to establish a retaliation narrative without changing operational behaviour. Voluntary anchoring, insurer caution and port delays would account for much of the observed disruption.
One or more credibly corroborated US-Iran or Gulf-state kinetic incidents, but partial commercial access remains, unlikely at 30 per cent. The IRGC retaliation claim, US warnings and repeated maritime incident reporting support further confrontation. Continued transits and the absence of a verified general Iranian closure would limit the effect to delays, selected diversions or higher-risk voyages.
Operators and insurers render Hormuz commercially unusable without an Iranian general denial of passage, unlikely at 20 per cent. Several attacks, confirmed commercial-vessel damage, sustained anchorage growth or sharply higher war-risk restrictions would cause operators to stop transiting without a state declaration. Three consecutive days of zero AIS-verified commercial transits with UKMTO or JMIC corroboration would support this pathway.
Iran formally declares or enforces a general denial of passage, unlikely at 10 per cent. This is the low-probability, high-impact wildcard. It requires a named Iranian authority to issue an explicit denial or verified enforcement against multiple commercial vessels. The supplied reporting provides no such order.

Outlook

A confirmed or credibly corroborated kinetic incident involving US, Iranian or Gulf-state forces is likely at 70 per cent over the next 14 days, with low confidence. A direct US kinetic strike on Iranian territory over the next 72 hours remains unlikely at 20 per cent, with moderate confidence. A formal Iranian closure over 14 days remains unlikely at 10 per cent, with moderate confidence because the new evidence increases escalation risk without establishing an official denial of passage.

Selective Iranian coercion is likely at 60 per cent over 14 days, with low confidence. A commercial de facto closure caused by operator avoidance, insurer withdrawal or inability to obtain safe passage remains unlikely at 20 per cent. The commodity-vessel estimate remains 60 per cent for fewer than 10 crossings in each of the next three 24-hour periods, with low confidence; it is retained from the previous briefing because no current comparable Kpler count was supplied.

Houthi-Saudi military exchanges are likely at 70 per cent over 14 days, with moderate confidence. A confirmed Houthi attack on a merchant vessel in Bab el-Mandab is unlikely at 30 per cent, with low confidence. An Israeli strike on Iran is a roughly even chance at 50 per cent over 14 days, with low confidence. These secondary judgements provide regional escalation context but do not alter the Hormuz closure estimate.
