Unresolved US-Iran terms keep Hormuz transit, energy flows and maritime security under acute pressure, while renewed fighting in northern Ethiopia further erodes a previously stabilising peace framework.
Since the previous edition
Renewed fighting in northern Ethiopia and a larger Russian drone attack sharpen the conflict picture, while Hormuz diplomacy remains stalled without an access arrangement.
Washington’s rejection left no reopening protocol, keeping Gulf crude flows, tanker operations and oil markets exposed to security incidents.
More than 120 drones reportedly struck multiple regions, intensifying civilian and emergency-service exposure without a verified aerial ceasefire.
The United States’ rejection of Iran’s conditional proposal leaves the Strait of Hormuz without an agreed reopening arrangement, while Qatar continues indirect contacts and shipping movements remain sharply reduced.
Taiwan says it detected three PLA aircraft sorties, five PLA Navy vessels and four official ships around Taiwan in the 24 hours ending September 28, including one aircraft crossing the Taiwan Strait median line into the northern ADIZ.
Ana Brnabić has assumed acting presidential duties after Aleksandar Vučić’s 27 September resignation, starting a statutory process requiring Serbia to hold a presidential election within three months while campaigning continues for the 25 October parliamentary vote.
Renewed fighting across northern Ethiopia, including the reported seizure and occupation of airports in Tigray, has materially undermined the November 2022 Pretoria cessation-of-hostilities agreement.
Russian drone attacks across Ukraine on 28 September killed at least nine people and injured more than 80, according to Ukraine’s president, underscoring the continuing absence of an implemented halt to long-range air strikes.
The United States on September 28 imposed or announced visa restrictions affecting 27 current or former officials and relatives from Bolivia, Colombia, Ecuador and Peru, with the largest group reported to be Bolivian judicial figures.
Analysis
The operating picture is being driven principally by unresolved maritime access through the Strait of Hormuz, renewed fighting in northern Ethiopia, and Russia’s continuing long-range drone campaign against Ukraine. These developments create distinct but material pressures on energy flows, civilian protection, military readiness and crisis diplomacy; the evidence does not support treating them as a single connected escalation cycle.
Energy risk remains volatile as the United States’ rejection of Iran’s conditions left the Strait of Hormuz without a verified reopening arrangement on 29 September. Reported vessel movements remain sharply reduced after attacks on commercial shipping, sustaining a risk premium around regional crude exports and tanker availability even though a complete closure has not been established.
Exposure is most direct for Gulf crude exporters, tanker operators and marine insurers. Higher crude and freight uncertainty can support upstream producers and integrated majors with production outside the affected route, while refiners, airlines and fuel-intensive logistics operators face higher input-cost and supply-timing risk if disruption persists.
Moderate confidence · Volatile · Volatile
The absence of an agreed transit arrangement through the Strait of Hormuz leaves cargo scheduling dependent on an unresolved diplomatic process and a fragile maritime-security environment.
Gulf crude exporters, tanker owners and marine insurers are the most immediately exposed, while buyers reliant on timely regional cargoes face greater delivery uncertainty.
Signal to watchA verified and sustained recovery in commercial vessel transits through the Strait of Hormuz would indicate that operational access is improving.
Persistent uncertainty around passage can maintain upward pressure on crude and shipping-risk costs without implying a uniform supply loss across global oil markets.
Refiners, airlines and fuel-intensive logistics firms are more exposed to cost pressure than producers with diversified output, although the scale of market transmission remains uncertain.
Signal to watchConfirmed export volumes and freight or insurance pricing for Gulf cargoes will clarify whether disruption is moving beyond transit uncertainty into sustained physical-market tightening.
Markets face an elevated, energy-led volatility impulse because negotiations over transit through the Strait of Hormuz remain unresolved and reported shipping movements are sharply reduced. The supplied evidence records higher oil prices and weaker sentiment, but it does not establish a broad global financial dislocation.
The immediate transmission is concentrated in crude, tanker, insurance and fuel-sensitive equities rather than across all asset classes. A verified reopening arrangement or durable recovery in transits would be the clearest countervailing signal.
Moderate confidence · Volatile · Volatile
The failed reopening proposal ties oil-market pricing to uncertain mediation outcomes and to the security of commercial transit through a major export chokepoint.
Crude-linked assets, tanker operators and insurers are likely to remain especially sensitive to negotiation setbacks or additional attacks on commercial vessels.
Signal to watchAn announced and independently verifiable transit arrangement would test whether the current oil-risk premium can unwind.
Trade and supply-chain pressure is worsening around the Strait of Hormuz because commercial shipping is reportedly sharply reduced and no verified reopening protocol has emerged from indirect contacts. The evidence does not establish a full closure, but predictability for cargo movements has deteriorated.
The impact is concentrated on Gulf maritime traffic and cargoes using the strait, rather than on global trade broadly. Restored regular vessel movement would provide the strongest evidence that the disruption is easing.
Moderate confidence · Volatile · Volatile
Attacks on commercial shipping and the absence of a transit agreement increase uncertainty over voyage timing, routing decisions and insurability for cargoes moving through the strait.
Shippers and importers dependent on Gulf routes face the most immediate exposure to delayed or more costly cargo movements.
Signal to watchSustained commercial vessel traffic at more normal levels would show whether route reliability is being restored.
Diplomatic pressure is elevated and volatile because Qatar’s indirect contacts have not produced an agreed framework for ending fighting and restoring safe passage through the Strait of Hormuz. The United States rejected Iran’s conditional proposal, leaving sanctions relief, maritime access, a ceasefire involving Lebanon and nuclear talks bundled into unresolved terms.
Regional diplomatic risk is also rising around northern Ethiopia, where Addis Ababa’s military leadership has alleged external backing for Tigrayan forces. Those allegations were denied and remain unsubstantiated in the available evidence, so they raise tension but do not establish interstate intervention.
Moderate confidence · Volatile · Volatile
Qatari contacts continue, but the parties have not agreed workable conditions for restoring predictable transit, leaving diplomacy exposed to further bargaining failure.
Commercial passage and energy-market confidence remain dependent on unverified negotiations rather than an operationally confirmed arrangement.
Signal to watchA jointly acknowledged agreement specifying passage arrangements would show whether mediation has moved from contact to implementation.
Ethiopian military allegations against Eritrea, Sudan and Egypt add regional diplomatic pressure while denials and the lack of independent corroboration limit conclusions about outside involvement.
The immediate exposure is to further deterioration in interstate relations rather than a confirmed expansion of the conflict across borders.
Signal to watchCorroborated evidence of cross-border military support or a formal response by an accused government would materially change the regional risk assessment.
Military and security conditions are worsening through three direct drivers: attacks on commercial shipping amid the unresolved Strait of Hormuz dispute; renewed federal–Tigrayan fighting that has undermined Ethiopia’s 2022 cessation framework; and Russia’s nationwide drone attack on Ukraine on 28 September. The latter two conflicts impose immediate operational burdens on air defence, civilian protection and territorial security.
Pressure is severe but geographically concentrated rather than a single global military escalation. Taiwan’s reported PLA activity sustains routine operational demands on Taiwan’s forces, but the available official report does not show a new exercise, blockade measure or broader change in force posture.
Moderate confidence · Worsening · Rising
Attacks on commercial vessels and the lack of a verified reopening mechanism keep shipping exposed to further incidents in the Strait of Hormuz.
Commercial crews, vessels and escort or surveillance assets operating around the strait face the most immediate security exposure.
Signal to watchA further verified attack on a commercial vessel or a sustained security-backed transit arrangement would determine whether risk is escalating or being contained.
Renewed fighting and the reported seizure or occupation of airports in Mekelle, Axum and Shire demonstrate that the 2022 framework is no longer containing armed confrontation.
Control of northern transport nodes and the security of communities in affected areas are immediately exposed to continued or widening fighting.
Signal to watchVerified changes in control of the named airports or expansion of fighting into additional northern areas would indicate the conflict’s next operational direction.
Russia’s reported deployment of more than 120 drones across Ukraine requires continued interception, alert and emergency-response activity across multiple regions.
Ukraine’s air-defence capacity and urban civil-protection systems remain the most directly stressed assets, especially where damage assessment and rescue work are ongoing.
Signal to watchSubsequent verified strike volumes and Ukraine’s reported interception performance will show whether the operational burden is being sustained or intensifying.
Political stability is worsening most clearly in Ethiopia, where renewed conflict has rendered the 2022 Pretoria framework ineffective as a restraint and raises pressure on federal authority across the north. In Ukraine, continued nationwide air strikes sustain pressure on civilian administration and emergency services, though the supplied evidence does not show a change in national political control.
Serbia’s interim presidency and parallel election timetable add domestic uncertainty, but the constitutional succession process is functioning and the evidence does not establish an immediate policy rupture. The United States’ targeted visa restrictions may intensify political contestation in Bolivia, yet their regional effect remains limited and uncertain.
Moderate confidence · Volatile · Volatile
The return of fighting across northern Ethiopia shifts pressure from managing an imperfect peace arrangement to containing an active conflict with contested regional implications.
Ethiopian federal authorities and communities in northern regions are exposed to further instability if fighting expands or key transport nodes remain contested.
Signal to watchVerified territorial changes, additional armed fronts or a renewed negotiated cessation effort would clarify whether instability is deepening or being contained.
Aleksandar Vučić’s resignation has placed Ana Brnabić in an interim presidency while Serbia must organize a presidential election alongside the scheduled parliamentary contest.
Political competition and government-formation uncertainty are concentrated in Serbia’s coming electoral period, while constitutional succession provides a continuity mechanism.
Signal to watchThe formal calling of the presidential election and the outcome of the 25 October parliamentary vote will determine whether the transition remains orderly.
Continuing developments
Standing intelligence files track the most durable current situations across editions, decisions, and strategic consequences.
Houthi attacks and external defensive support continue to shape Saudi air-defence requirements and Red Sea operating risk.
The UK has committed an RAF Voyager to support Saudi defensive aviation as Houthi attacks continue. The available evidence does not establish British combat participation, a maritime closure, or confirmed disruption to Saudi energy exports.
Key assumptionThe UK deployment proceeds within the defensive refuelling role described by the Ministry of Defence.
Last material update:
The UK confirms that the RAF Voyager has begun operations or announces an expanded role beyond defensive refuelling.
Authorities or operators confirm damage or sustained disruption affecting Red Sea shipping, Yanbu, or Saudi export infrastructure.
Russia’s long-range strike campaign continues while no mutually confirmed operational restraint framework is in force.
Russia’s reported drone attack across Ukraine on 28 September caused civilian casualties and damaged urban sites in several regions. The available evidence does not show an implemented agreement suspending long-range attacks.
Last material update:
Russia and Ukraine publicly confirm common terms, protected targets, monitoring arrangements or an implementation date for limits on long-range attacks.
A documented multi-day decline in reciprocal long-range strikes follows an announced and mutually acknowledged arrangement.
Maritime access through Hormuz remains tied to unresolved US-Iran security, sanctions and ceasefire conditions.
The United States has rejected Iran’s reported conditional reopening proposal, while Qatari mediation continues and no verified transit arrangement exists. Reported reduced vessel movements keep energy exporters, tanker operators and cargo owners exposed to uncertain passage.
Key assumptionNo undisclosed agreement has altered the reported negotiating positions or maritime operating conditions.
Last material update:
Iran, the United States, or Qatar confirms transit procedures, reciprocal commitments and an effective date for commercial passage.
Maritime authorities or operators report sustained normalization of Hormuz traffic under announced security conditions.
Selective tariff stabilisation is proceeding alongside unresolved technology controls and wider strategic competition.
The trade truce now runs through 10 January 2027 and includes agreed reciprocal tariff reductions, but those cuts await domestic legal procedures. Advanced-semiconductor controls remain outside the arrangement, limiting the scope of bilateral stabilisation.
Key assumptionBoth governments complete domestic procedures required for simultaneous tariff implementation.
Last material update:
Either government publishes effective dates, covered goods, rates, or customs procedures for reciprocal tariff reductions.
Either government revises advanced-semiconductor controls or announces a bilateral arrangement addressing those restrictions.
Geography
The United States’ rejection of Iran’s conditional proposal leaves the Strait of Hormuz without an agreed reopening arrangement, while Qatar continues indirect contacts and shipping movements remain sharply reduced.
The dispute links maritime access through a major energy chokepoint to contested military de-escalation, sanctions relief and nuclear diplomacy. Until the parties agree on workable terms, mediation rather than an operational reopening plan remains the main route to restoring predictable passage.
The uncertainty has contributed to higher oil prices and weaker market sentiment. Reduced shipping also raises practical risks for regional crude exports and cargo movements, while the absence of a verified transit arrangement limits confidence that normal flows can resume.
Renewed fighting across northern Ethiopia, including the reported seizure and occupation of airports in Tigray, has materially undermined the November 2022 Pretoria cessation-of-hostilities agreement.
The renewed hostilities represent a major breakdown of the framework that ended the 2020-2022 Tigray war. Control of airports and fighting across multiple northern fronts raise immediate risks to civilian movement, humanitarian access and internal security in Ethiopia.
The Ethiopian military's allegations also increase diplomatic pressure in the Horn of Africa, but they do not establish a confirmed cross-border intervention or interstate conflict. Their significance will depend on whether evidence of external involvement emerges or whether the accusations trigger further state action.
Russian drone attacks across Ukraine on 28 September killed at least nine people and injured more than 80, according to Ukraine’s president, underscoring the continuing absence of an implemented halt to long-range air strikes.
The attack demonstrates Russia’s continuing ability to impose nationwide air-defence and civil-protection pressure despite Ukraine’s reported interceptions. The broad geographic spread and civilian damage increase the immediate burden on emergency response, urban infrastructure and air-defence resources.
It also confirms that no mutually confirmed operational framework suspending long-range air attacks is in force in the reviewed record. The European Union’s separate 28 September restrictive measures against 10 individuals and 17 entities over the alleged deportation and forcible transfer of Ukrainian children are related war context, not a cause of the strikes.
Ana Brnabić has assumed acting presidential duties after Aleksandar Vučić’s 27 September resignation, starting a statutory process requiring Serbia to hold a presidential election within three months while campaigning continues for the 25 October parliamentary vote.
The resignation creates parallel electoral processes at a time of sustained domestic political tension following protests linked to the November 2024 Novi Sad station-canopy collapse. The immediate institutional arrangement preserves continuity at the presidency but compresses the timetable for a separate presidential contest.
The parliamentary result and the presidential-election process will determine Serbia’s next executive configuration. The available evidence does not establish an immediate change in Serbian foreign, security or economic policy.
Taiwan says it detected three PLA aircraft sorties, five PLA Navy vessels and four official ships around Taiwan in the 24 hours ending September 28, including one aircraft crossing the Taiwan Strait median line into the northern ADIZ.
The activity sustains day-to-day operational pressure on Taiwan’s armed forces and keeps the median-line and northern-ADIZ operating areas active points of military friction. Taiwan must continue to commit air, naval and coastal-defence assets to detection and monitoring.
The reported scale is limited, however, and the available evidence does not establish an acute escalation or a broader change in PLA force posture. The immediate significance is therefore the persistence of coercive military presence rather than a verified shift toward a blockade or major exercise.
The United States on September 28 imposed or announced visa restrictions affecting 27 current or former officials and relatives from Bolivia, Colombia, Ecuador and Peru, with the largest group reported to be Bolivian judicial figures.
The restrictions give Washington a targeted means of applying diplomatic pressure to judicial and political actors while immediately limiting designated individuals' access to the United States. Their concentration on Bolivian prosecutors and judges raises the risk of sharper domestic contestation over judicial independence and anti-crime enforcement.
The inclusion of officials and relatives from four countries broadens the bilateral signal beyond Bolivia, but the reviewed evidence does not show associated criminal cases, financial restrictions, trade measures or coordinated enforcement by Bolivia, Colombia, Ecuador or Peru.
