Hormuz remains below baseline as Aden missile incident adds Houthi risk

As of 22 October 2026 at 00:24 UTC, no new qualifying event is confirmed in the 21 October to 22 October reporting window in the Strait of Hormuz or its Gulf of Oman approaches. A qualifying event means a projectile or mine impact, attempted attack, armed boarding attempt or damaging attack involving a merchant vessel or armed craft in those waters, excluding the Arabian Sea off Yemen, the Red Sea, Bab al-Mandab and Saudi coastal waters near Al Jubail; the next 24 to 72 hours carry a 65 per cent likelihood of such an event, moderate confidence.

Hormuz Remains Severely Disrupted, Sudan Toll Reaches 153, Red Sea Still Open

The Strait of Hormuz remains severely disrupted but not physically closed under the 24-hour no-transit definition. A new qualifying attack or attempted attack from 21 to 22 October is assessed as likely, at 70 per cent with moderate confidence. A qualifying event means a projectile or mine impact, attempted attack, armed boarding attempt or damaging attack involving a merchant vessel or armed craft in the Strait of Hormuz or its Gulf of Oman approaches. It excludes incidents in the Arabian Sea off Yemen, the Red Sea, Bab al-Mandab and Saudi coastal waters near Al Jubail.

Hormuz passage remains exposed as Iran alleges tanker mine strike and US-Israeli strike planning continues

Commercial passage through the Strait of Hormuz remains reduced and exposed, but the supplied reporting does not establish a physical closure, defined here as no independently verified merchant transit for 24 consecutive hours. The IRGC Navy's unverified 19 October tanker-mine allegation and reported US-Israeli contingency planning sustain a 70 percent assessment of a qualifying attack or attempted attack through 22 October, unchanged from the prior briefing, with moderate confidence.

Global Strategic Risk: Hormuz Disruption Persists as Ukraine Strikes and Nepal Transition Unsettle

Commercial passage through the Strait of Hormuz remains reduced but is not physically closed. Through 22 October, a new qualifying attack or attempted attack is assessed at 70 percent and a coercive maritime encounter at 85 percent, while Nepal's reported transfer from KP Sharma Oli to Sushila Karki remains less securely corroborated than the reported protest deaths and Oli resignation.

Daily · October 18, 2026

Hormuz Passage Remains Disrupted as UKMTO Reports 12 Attacks and Ukraine Energy Strikes Continue

Commercial passage through the Strait of Hormuz and its Gulf of Oman approaches is likely to remain disrupted through 20 October: a new reported attack or attempted attack is likely, assessed at 70 percent with moderate confidence, and a coercive maritime encounter is very likely, assessed at 85 percent with moderate confidence. The available reporting does not establish a physical closure, defined here as no verified merchant transit for 24 hours; the 18 October armed-skiff incident off Yemen is in the Arabian Sea and is not evidence of a Hormuz attack.

Hormuz shipping remains under attack as Ukraine, Sudan and the Sahel add fresh escalation

Commercial shipping in the Strait of Hormuz and its Gulf of Oman approaches is likely to remain disrupted from 17 through 19 October, with a 60-80% probability of another attack or disabling incident and an 80-95% probability of a coercive maritime encounter, both with moderate confidence. A new US strike on Iran before 3 November remains unlikely at 20-40%, with low confidence. Russia very likely conducted the reported 16 October mass drone attack on Ukraine, while the Nyala market strike and the ISWAP attack on Mairari military base add new civilian and military casualties without resolving attribution.

Hormuz Shipping Losses Persist as Russia Adds a Second High-Volume Strike Wave on Ukraine

Commercial shipping in the Strait of Hormuz and Gulf of Oman is very likely to remain disrupted through 19 October. Further physical attacks or disabling incidents are assessed at 60-80 percent, and a coercive maritime encounter at 80-95 percent, both with moderate confidence. Russia very likely launched a second consecutive high-volume drone wave against Ukraine, while a new US strike before 3 November or an Israeli strike before 27 October remains unlikely, at 20-40 percent for each, with low confidence.

GFS Pride Sinking Confirms Hormuz Disruption as Russian Strikes Hit Ukraine’s Grid

A further physical attack or disabling incident against commercial shipping in the Strait of Hormuz or Gulf of Oman is likely by 18 October, while a coercive encounter is very likely. Russia almost certainly conducted the 14 October strike on Ukrainian energy infrastructure, and Saudi-Houthi exchanges are likely to continue; no reviewed reporting establishes a decision by the US or Israel to resume direct strikes on Iran before their respective elections.

Daily · October 14, 2026

Hormuz Shipping Remains Severely Disrupted as Ukraine and Black Sea Strikes Add Pressure

Commercial shipping in and around the Strait of Hormuz is very likely to face another attack or coercive encounter within 14 days, while traffic remains about one-fifth of its historical level. The Saudi-Houthi confrontation and Russia’s high-volume attack on Ukraine are sustaining wider conflict and energy risks; the two Bulgarian ship incidents add a serious but unattributed Black Sea maritime threat.

Daily · October 13, 2026

Hormuz Shipping Attacks Continue as US Blockade and Saudi-Houthi Retaliation Widen Regional Risk

Commercial shipping in and around the Strait of Hormuz is very likely to face further attack or coercive interference over the next 14 days. The prior 70% forecast has been overtaken by qualifying incidents involving named vessels before its 13 October deadline, raising the estimate to approximately 85%; the United States and Iran remain unlikely to agree a near-term reopening, while Saudi-Houthi retaliation adds a second escalation channel.

Daily · October 12, 2026

Hormuz Vessel Risk Persists as US Maritime Enforcement and Riyadh Strike Open Separate Escalation Paths

Commercial shipping in the defined Hormuz area is very likely to face another attack, warning or coercive restriction over the next 14 days, with moderate confidence. The prior 70% forecast of a further verified attack, boarding, forced diversion or near miss involving a named commercial vessel remains in force temporarily because the 13 October 0125Z deadline has not expired; if no qualifying event occurs by then, the estimate will fall to approximately 55%.

Daily · October 11, 2026

Hormuz remains navigable but exposed, with the 70% vessel-incident forecast unchanged

A further verified attack, boarding, forced diversion or near miss involving a named commercial vessel in the Strait of Hormuz, the Persian Gulf north of Qatar or waters off the UAE has a 70% probability by 13 October 0125Z, likely, with moderate confidence. The 9 October GEM NO.2 strike is a verified baseline incident, while the 10 October IRGC claim concerning NV Sunshine remains uncorroborated and does not count as a new qualifying event; a direct US strike on Iran before 3 November remains unlikely.

Daily · October 10, 2026

Kyiv outages deepen as Blue Nile fighting is reported; Hormuz risk holds

Russian strikes affecting Ukraine's energy system are likely to continue over the next 72 hours, with a 70 percent probability and moderate confidence; Ukrenergo and DTEK have already reported emergency restrictions around Kyiv. A further qualifying commercial-vessel incident in the Hormuz area is also assessed at 70 percent by 13 October, unchanged from the prior estimate, while the reported RSF offensive towards Damazin remains a roughly even chance at 45 percent and low confidence.

Daily · October 9, 2026

Hormuz risk rises after disputed Acers report as US strike posture remains unresolved

Further attacks or coercive interference against commercial vessels near the Strait of Hormuz are likely, with a 70% probability over the next 72 hours and moderate confidence. UKMTO reported a dated incident involving the tanker Acers near Qatar, while India reported injuries aboard On Peace, but the supplied evidence does not establish whether these are two separate attacks; some commercial movement through Hormuz is likely to continue, with moderate confidence.

Hormuz LNG Report Is Unresolved; 72-Hour Vessel-Incident Forecast Holds at 65%

The Greek Ministry of Maritime Affairs and Insular Policy reported contact between an unidentified object and a Greek-owned LNG carrier near the Strait of Hormuz on 7 October, but the supplied material does not identify the vessel, position, event time or damage. Because the report cannot yet be deconflicted from the 5 October On Peace incident and UKMTO advisories, we retain the prior 65% likelihood of another qualifying Hormuz commercial-vessel incident within 72 hours, with moderate confidence; a sustained closure remains unlikely.

Daily · October 7, 2026

Hormuz remains navigable but hazardous as tanker incidents and US interdictions constrain Iranian exports

For shipowners, Gulf exporters and US naval forces, the immediate Hormuz risk is repeated voyage interruption rather than a demonstrated closure. There is a 65% probability, likely, of another qualifying commercial-vessel incident within 72 hours, with moderate confidence. Saudi-backed Yemeni forces are also likely to continue fighting the Houthis around Dhubab, Mokha and Bab al-Mandab, but neither side has demonstrated operational control of the shipping lane.

Dual chokepoint risk rises after Hormuz tanker turn-back and Yemen offensive

There is a 65% probability of another verified commercial-vessel attack, boarding, forced diversion or near miss in or near the Strait of Hormuz within 72 hours, unchanged from the previous brief, with moderate confidence. Yemen’s internationally recognised government has announced operations against Ansar Allah near Bab al-Mandab, but the evidence supports continued fighting rather than established control of the waterway; a major renewed US-Iran air campaign before 19 October remains unlikely at 25%, with moderate confidence.

Daily · October 5, 2026

Hormuz shipping attacks continue as Ukraine meets prior strike threshold and Sudan fighting threatens El Obeid

Further attacks on commercial vessels in or near the Strait of Hormuz are likely over the next 14 days, at 65 per cent probability and moderate confidence, while a major renewed US-Iran air campaign before 19 October is unlikely, at 25 per cent and moderate confidence. The Ukrainian Air Force's reported 135-weapon salvo probably meets the prior large-strike forecast, while the Sudanese Armed Forces probably improved their position in North Kordofan; there is a 60 per cent chance of major fighting around El Obeid within 14 days, but low to moderate confidence because the territorial and attack reporting is not independently verified.

Daily · September 24, 2026

No New Current-Window Escalation Reported, but Russia-Ukraine Strike Cycle Persists

The supplied reporting contains no materially new Russia-Ukraine event dated 23 or 24 September. Russia remains assessed at an 85 per cent probability, moderate confidence, of conducting at least one attack involving 100 or more launched drones or missiles against Ukrainian infrastructure by 8 October, while Ukraine has a 75 per cent probability, moderate confidence, of another deep strike against a Russian refinery, military facility or logistics node by 24 October. The principal consequence is continued pressure on Ukrainian electricity and heating resilience, without verified evidence of a wider battlefield breakthrough.

Hormuz traffic remains severely constrained as US-Iran contact fails to change military risk

The US-Iran confrontation is very likely to remain active through 6 October, while commercial traffic through the Strait of Hormuz is very likely to remain severely constrained through 25 September. Reported contact between Abbas Araghchi and Steve Witkoff, and Iran's conditional seven-day reopening offer, have not produced verified traffic normalisation; Houthi pressure on Saudi Arabia continues to expose Saudi energy infrastructure, Red Sea shipping and CENTCOM forces.
