A market stress-tested beyond precedent
No six-year period in the modern insurance era has produced four distinct macro-level shocks, each operating through a different mechanism, each affecting different lines of business, and each demanding a structural market response. Yet that is precisely what the specialty reinsurance market has navigated between 2020 and 2026.
COVID-19 demonstrated the limits of systemic risk coverage. The Russia-Ukraine war exposed structural vulnerabilities in aviation war underwriting and drove a generation-defining repricing cycle. The inflation and interest rate shock corrected years of inadequate pricing while leaving unresolved structural challenges in casualty reserves. And the Strait of Hormuz crisis — the most acute current dislocation — is now testing whether the private insurance market can provide meaningful coverage for geopolitical risk in the world's most critical energy corridor.
The immediate trigger for this note is the developing Hormuz crisis. Since late February 2026, following US and Israeli military strikes on Iran, the Islamic Revolutionary Guard Corps has imposed effective control over the strait. The IRGC has conducted over 21 confirmed attacks on merchant ships, laid sea mines, and introduced a transit clearance regime charging up to $2 million per tanker — payable in Chinese yuan or cryptocurrency, bypassing the dollar-based financial system. Ship traffic has fallen from over 100 vessels per day to approximately 10. The IEA estimates that approximately 20 million barrels per day of oil supply — roughly one-fifth of global consumption — has been disrupted. The insurance market response has been the most severe since the Iran-Iraq Tanker War of the 1980s.
"The Hormuz crisis is not a tail event that will pass without consequence. It is the latest — and currently the most severe — demonstration that the boundary between private insurance and state-backed risk management is shifting."
The four shocks — a structured comparison
Each shock arrived with limited precedent in the modern insurance era. Each generated fundamental debates about policy wording, coverage scope, and claims settlement. Each produced a repricing response that, cumulatively, contributed to the hardest specialty reinsurance market of the past 25 years. The critical insight is that they are not independent episodes — they are cumulative, compounding events that have permanently shifted the operating environment.
2020–2021
COVID-19
Systemic — all geographies, all sectors simultaneously
~$107bn global insured losses. The largest non-catastrophe insurance loss event in history.
Pricing impact
All specialty lines +5–15% at January 2021 renewals. Event cancellation capacity largely closed. Trade credit +30–50%. D&O +20–40%.
Structural legacy
Permanent communicable disease exclusions in commercial BI. Pandemic risk now broadly uninsurable without state backing. Mandatory BI wording clarity introduced at Lloyd's.
2022–ongoing
Russia–Ukraine War
Geographically concentrated, asset-class specific
Largest aviation insurance loss event on record. 400–600 Western-leased aircraft stranded; $10–13bn commercial value; ~$4.5bn insured exposure.
Pricing impact
Aviation war +100%+ (e.g. Emirates). January 2023: global property cat +37%, US property cat +50%, retro +50%+. Dedicated reinsurance capital fell 15.7% to $355bn.
Structural legacy
Dual-flag aircraft risk embedded in underwriting. Lloyd's mandated state-sponsored cyber exclusions (March 2023). Landmark UK High Court judgment June 2025 awarded AerCap $1bn+.
2023–present
Red Sea & Strait of Hormuz
Choke-point specific — escalating severity
War risk premiums rose 40× on Red Sea routes. Hormuz: premiums from 0.25% to 3.5–10% of vessel value per transit. Traffic collapsed from 100+ to ~10 vessels per day.
Pricing impact
Red Sea: 0.025% to 1%+ per voyage. Hormuz: 3.5–10% of hull value per transit. VLCCs quoted in double-digit millions per trip. Many underwriters declined to offer cover at any price.
Structural legacy
Lloyd's JWC designated entire Arabian Gulf as conflict zone. All 12 International Group P&I clubs issued 72-hour war cover cancellation notices. Choke-point risk permanently repriced.
2021–2023
Global Inflation & Rate Shock
Macro-driven — all lines, cumulative erosion
Claims inflation added ~$30bn to industry loss costs in 2021 above historical trend. Reinsurance capital cost rose from ~8% to 11%+ in H1 2023.
Pricing impact
January 2023: hardest renewal in a generation. Global property cat +37%, US property cat +50%, retro +165% cumulative since 2017, D&F +160% since 2017.
Structural legacy
Inflation indexation clauses now standard in property policies. Mandatory cedant valuation audits at renewal. US social inflation in casualty: structural and unresolved.
The cumulative repricing — six years in numbers
The rate changes produced by these four shocks are not comparable to a normal market cycle. The January 2023 renewal season was described as the hardest in a generation by every major market analyst. Marine war pricing for Hormuz transits now represents a fundamentally different order of magnitude from pre-crisis baselines.
The Hormuz crisis — why this one is different
The Strait of Hormuz crisis is qualitatively more severe than the Red Sea disruption for three structural reasons that underwriters, boards, and risk managers must understand clearly.
01
Scale of trade affected
The Hormuz strait carries approximately 20 million barrels of oil per day — roughly one-fifth of global consumption. There is no alternative routing for Hormuz. Disruption here is irreversible until the political situation resolves.
02
Deliberateness of the mechanism
The IRGC's use of mines, a structured transit clearance regime, and tolls payable in non-dollar currencies represents a more deliberate and durable mechanism of control than Houthi attacks. This is state-level architecture for controlling a global chokepoint.
03
Complexity of the resolution pathway
Hormuz resolution requires a broader US-Iran-Gulf state framework involving multiple actors with divergent interests. The timeline for resolution is materially more uncertain — and insurance markets cannot sustain indefinite withdrawal of cover.
The market's response has reached a boundary rarely seen in peacetime commercial insurance: many underwriters declined to offer Hormuz cover at any price. The Lloyd's JWC designated the entire Arabian Gulf as a conflict zone. All 12 International Group P&I clubs issued 72-hour war cover cancellation notices simultaneously — the most significant collective P&I market action since the 1980s.
Forward scenario
If the crisis resolves within 3 months: Arabian Gulf transit premiums will remain at 1–3% of vessel value for 12–24 months. If the crisis extends beyond 6 months: expect formal restructuring of energy insurance programmes by major oil companies, expansion of government-backed war risk schemes, and sustained reduction in private reinsurance capacity for energy-related marine war risk — comparable to the structural changes that followed the Iran-Iraq Tanker War.
What is permanent and what will pass
The most important strategic question for insurance leadership is not how severe the current dislocation is, but how much of it represents a permanent narrowing of coverage scope versus a cyclical pricing premium that will eventually moderate. The evidence across all four shocks points to a clear pattern: event-driven shocks produce both structural exclusions and cyclical pricing effects, but the structural exclusions do not reverse.
Strategic implications by audience
The response to these shocks cannot be uniform. Insurers and reinsurers, brokers, and corporate buyers each face materially different exposures and require different strategic actions. The implications below are prioritised for the immediate operating environment, with the Hormuz crisis as the primary near-term concern.
Insurers and Reinsurers
Underwriting discipline
Mandate explicit annual wording reviews for all specialty lines. The COVID-19 experience showed that vague policy language creates existential legal risk. The Hormuz crisis is repeating this dynamic in marine war and cargo. Clarity of coverage scope is non-negotiable.
Pricing maintenance
Resist premature soft-cycle pressure. The January 2023 repricing corrected structural under-pricing accumulated over 2015–2020. Softening too quickly leaves the market exposed to the next shock with inadequate rate and reserve buffers.
Choke-point exposure assessment
Identify aggregate exposure to vessels transiting the Arabian Gulf, energy assets in the Persian Gulf, and contingent BI policies with supply chain triggers linked to Gulf oil flows. This assessment must inform immediate capacity management decisions.
Casualty reserve stress-testing
Reserves set in 2020–2022 for US casualty lines may be structurally inadequate due to social inflation. Prior-year reserve development should be stress-tested against nuclear verdict frequency and litigation funding trends.
Brokers
Proactive coverage mapping
Clients — particularly corporate energy buyers, shipping companies, and manufacturers with Gulf supply chains — need clear communication about what their current policies do and do not cover. Coverage disputes are more damaging than known coverage gaps.
Access to government-backed facilities
For risks genuinely unplaceable in the private market, brokers should actively facilitate access to MIGA (World Bank), national export credit agencies (UKEF, US EXIM, SACE), and specialist state-backed pools. This requires different placement capabilities than standard market placements.
Real-time market intelligence
Capacity availability, premium levels, and coverage terms are changing weekly. Brokers with real-time intelligence on JWC designations, P&I club positions, and underwriter appetite will be significantly more valuable than those operating on stale information.
Corporate Buyers
Contingent BI review — now
Policies written before 2024 may not cover Hormuz-related supply chain disruption if war exclusions apply to IRGC actions. Review immediately for crude oil supply chains, LNG contracts, petrochemical inputs, and container trade through the Gulf.
Incorporate war risk into procurement
Marine war premiums of 3.5–10% of vessel value per transit — versus a pre-crisis baseline below 0.5% — represent a step-change in shipping economics that must flow through to contract pricing and hedging strategies.
Map uninsured exposures explicitly
Pandemic, active interstate war, and some geopolitical disruptions are now excluded from standard commercial policies. Maintain an explicit map of uninsured or uninsurable exposures. Do not assume historical coverage scope still applies.
Five conclusions for market leadership
Pandemic exclusions are permanent
Communicable disease exclusions are now standard in commercial BI across the US, UK, and EU. Pandemic risk has left the private insurance market. This is not a temporary pricing adjustment.
Aviation war underwriting has been fundamentally reformed
Dual-flag risk scrutiny, sanctions-list alignment, and lessor-operator-registrar analysis are now embedded in underwriting practice. The June 2025 High Court judgment sets precedents that will shape future disputes.
Inflation indexation is now structural in property
Indexation clauses, cedant valuation audits, and elevated attachment points are a durable feature of property reinsurance, not cyclical measures that will be removed when inflation moderates.
Marine war capacity for active conflict zones is explicitly limited
The 72-hour P&I cancellation notices, JWC designation of the entire Arabian Gulf, and premium escalation to 3.5–10% represent the market reaching the boundaries of private insurance capacity for active geopolitical conflict.
The boundary between private insurance and state risk transfer is shifting
The organisations that navigate the next decade successfully will be those that build the capabilities and relationships to operate on both sides of this boundary — accessing government-backed mechanisms where private capacity reaches its limits.
The strategic imperative
The organisations that navigate the next decade successfully will be those that maintain underwriting discipline through the full cycle, invest in precise policy language and coverage clarity, build scenario-based capital planning that encompasses geopolitical risk, and develop the relationships and capabilities needed to access government-backed risk transfer mechanisms when private capacity reaches its limits. The question for CEOs, CUOs, and Chief Strategy Officers is not whether the boundary between private insurance and state-backed risk management will move further. It is how quickly they will adapt their businesses to operate effectively on both sides of it.
