The situation
Commercial passage through the Strait of Hormuz has reportedly improved with US Navy assistance, but volumes remain significantly below pre-war levels. The evidence does not support treating the waterway as either fully closed or restored to normal operations.
President Donald Trump is scheduled to meet Gulf Cooperation Council leaders and senior officials at the UN on September 22 to discuss the Iran war and attacks on Saudi Arabia attributed to Iran-backed forces. A second pressure point remains at the Bab el-Mandeb and Red Sea, where the Houthis have declared a blockade affecting Saudi shipping and have reportedly attacked Saudi-linked vessels and oil facilities; the UK announced on September 21 that an RAF aircraft would refuel Saudi aircraft conducting defensive missions.
Why it matters
The Strait of Hormuz and Bab el-Mandeb are the two principal maritime approaches for Gulf energy exports and wider regional trade. Partial Hormuz recovery reduces the risk of a complete interruption, but below-normal passage leaves oil shipping exposed to further security incidents, naval-access constraints and higher operational risk.
The US-GCC meeting puts maritime access and Saudi security at the centre of regional diplomacy, but no outcome or de-escalation has been established. US naval assistance and planned UK refuelling support show that external powers are already supporting protective and defensive measures rather than a confirmed settlement.
What changed
Some commercial traffic has reportedly resumed through Hormuz with US naval assistance, but passage remains below pre-war levels; the UK has also announced limited refuelling support for Saudi defensive missions.
The assessment
Current judgement
Partial recovery in Hormuz transit has reduced—but not removed—the regional energy-shipping disruption created by the wider conflict.
What could challenge this assessment
The available evidence is concentrated in two reports and does not include direct confirmation from the White House, Gulf governments, the UK government or maritime authorities.
Impacts
Military & Security
US naval assistance for Hormuz transits and UK refuelling support for Saudi defensive missions indicate active external involvement while maritime and air-security risks remain elevated.
Energy
Partial resumption of Hormuz traffic eases the risk of a total halt, but below-pre-war transit keeps Gulf oil-export logistics exposed to renewed disruption.
Trade & Supply Chains
Constrained access at Hormuz and reported threats affecting Saudi shipping near Bab el-Mandeb leave two critical regional maritime routes exposed to delay and rerouting risk.
Diplomacy
The September 22 US-GCC meeting elevates maritime access and Saudi security in regional diplomacy, but the evidence provides no confirmed agreement or de-escalation outcome.
Full edition assessment · Military & Security
Military and maritime-security conditions are volatile, driven principally by constrained commercial transit through the Strait of Hormuz, reported threats to Saudi-linked shipping near Bab el-Mandeb, and the United Kingdom's planned time-limited refuelling support for Saudi defensive missions. Partial Hormuz recovery with US naval assistance is an easing factor, but it has not restored normal operating conditions.
The most direct exposure remains Gulf maritime access and Saudi defensive capacity. Persistent PLA activity around Taiwan and the reported cyber campaign against Ukrainian and European defence-related targets maintain separate regional monitoring burdens, but the supplied evidence does not show a common escalation cycle.
Low confidence · Volatile · Volatile
Protection requirements remain elevated at Gulf chokepoints
Below-normal Hormuz passage and reported threats near Bab el-Mandeb require continued naval, air-defence and commercial-security attention, while the RAF contribution may extend Saudi defensive sortie endurance if it begins as planned.
Tankers, cargo operators and regional security forces remain exposed to abrupt access restrictions or threat-driven operational pauses.
Signal to watchVerified commercial transit data or an official maritime-security arrangement showing whether Hormuz access is returning toward pre-war levels.
Defence and drone-sector cyber exposure may increase
The reported campaign targeted Ukrainian and European government, defence, diplomatic and drone-related organisations using AI-assisted activity across multiple intrusion stages.
Organisations supporting Ukrainian defence and drone supply chains face the clearest reported espionage exposure, although successful compromises have not been independently established.
Signal to watchA Ukrainian or European authority identifies a confirmed compromise or links specific incidents to the reported campaign.
Full edition assessment · Energy
Energy transport risk remains elevated because commercial passage through Hormuz has only partially resumed and remains below pre-war levels, while reported threats to Saudi-linked shipping add a second exposure around Bab el-Mandeb. The partial recovery reduces the immediate risk of a complete interruption, but it does not establish normalised export logistics.
The clearest exposure is in crude and LNG shipping, tanker availability and marine insurance rather than confirmed damage to upstream production or refining capacity. Upstream Gulf producers retain export-access risk; refiners, airlines and fuel-intensive logistics operators are more exposed to higher freight, insurance and fuel-cost volatility if disruption persists.
Low confidence · Volatile · Volatile
Freight and insurance costs may remain elevated
Below-normal Hormuz transits keep voyage timing, security procedures and insurance assumptions under pressure even as some commercial traffic resumes with naval assistance.
Tanker owners, charterers and crude or LNG buyers dependent on Gulf liftings remain most exposed to route-specific delay and cost volatility.
Signal to watchSustained increases in verified Hormuz transit volumes without new security incidents would indicate that the transport risk premium is easing.
Two-route exposure limits the benefit of partial Hormuz recovery
Reported threats near Bab el-Mandeb mean improved access at Hormuz does not fully remove risk for Saudi-linked energy and shipping flows using Red Sea approaches.
Energy exporters and integrated majors with reliance on both Gulf and Red Sea maritime routes face a more complex logistics and contingency-planning burden.
Signal to watchVerified attacks on energy-linked shipping or infrastructure near Bab el-Mandeb would indicate that route risk is broadening rather than concentrating at Hormuz.
Full edition assessment · Trade & Supply Chains
Trade and supply-chain pressure is volatile because the Strait of Hormuz remains operational but below normal traffic levels, while reported Houthi threats to Saudi-linked vessels sustain uncertainty near Bab el-Mandeb. The partial Hormuz recovery is a material countervailing factor, preventing an assessment of broad route closure.
The pressure is concentrated in Gulf and Red Sea maritime logistics rather than evidence of a generalised global supply-chain disruption. Cargoes transiting these routes face the most immediate exposure to delay, rerouting, security procedures and increased operating costs.
Low confidence · Volatile · Volatile
Partial access leaves planning uncertainty for Gulf cargoes
Commercial movement through Hormuz has resumed only partially, leaving shippers to operate against uncertain transit availability rather than a confirmed reopening to normal conditions.
Time-sensitive cargoes and supply chains with limited inventory buffers face the greatest exposure to delay and schedule disruption.
Signal to watchA sustained official or industry-confirmed rise in commercial passages would show whether recovery is durable rather than escorted or episodic.
Red Sea risk compounds Gulf route planning
Reported threats to Saudi-linked shipping around Bab el-Mandeb add a second maritime-security variable to regional voyage planning even though the UK support mission is not described as maritime protection.
Operators serving Saudi-linked trade or using Red Sea approaches may face route-specific security reassessments and higher contingency costs.
Signal to watchIndependent confirmation of a threat incident affecting commercial traffic near Bab el-Mandeb would clarify whether risk is translating into wider disruption.
Full edition assessment · Diplomacy
Diplomacy is volatile across three distinct files: US-GCC engagement over regional conflict and maritime access, US-China consultations combining AI-risk communication with tariffs and critical minerals, and prospective US pressure on the International Criminal Court. Each channel has created a near-term decision point, but none has yielded a confirmed de-escalatory agreement or durable operating framework.
The ICC case is the most institutionally exposed because reported planning already covers financial, technology, witness-protection and detention continuity. The US-China AI proposal is potentially constructive, but no shared notification rules or Chinese acceptance have been publicly confirmed.
Low confidence · Volatile · Volatile
Economic-security negotiations remain coupled to crisis-management efforts
The US proposal for AI-incident notification was raised in talks that also covered tariffs and critical minerals, making progress on risk communication vulnerable to wider bilateral bargaining.
Technology, critical-mineral and trade stakeholders remain exposed to policy uncertainty until the leaders' meeting on 24 September produces a joint direction or leaves issues unresolved.
Signal to watchAn official readout from the 24 September US-China leaders' meeting stating whether either side has authorised follow-on work on AI incident communication.
Possible ICC measures could widen transatlantic institutional friction
Reported US warnings have prompted the Netherlands and the court to prepare continuity measures, even though no institution-wide designation or legal framework has been publicly confirmed.
The court's service providers and host-state support arrangements are most immediately exposed to uncertainty over payments, insurance, IT and related operations.
Signal to watchA published US legal instrument specifying the ICC's status, effective date, exemptions or licensing provisions would determine whether the risk becomes operational.
What to watch
- Do commercial transits through the Strait of Hormuz rise toward pre-war levels or remain materially constrained after the September 22 US-GCC meeting?
- Do the United States and Gulf states announce verifiable maritime-security or air-defence measures that alter access risks at Hormuz or Bab el-Mandeb?
