War-risk underwriting tightens in Singapore as Gulf airspace disruptions persist

Airlines reroute across Asia–Middle East routes as insurers reassess exposure and pricing risk.

Airlines are tightening routing, capacity planning and risk controls as restrictions across Gulf airspace persist due to the Iran war, pushing up operating costs and raising scrutiny from Singapore’s aviation insurance market.

“Even modest detours can cascade through a network — creating missed connections, tighter maintenance windows, and higher disruption‑management costs,” Tim Blakey, managing director for aviation and aerospace at Marsh Specialty of Marsh Ltd., told Insurance Asia.

Stephen Rudman, head of marine and regional aviation lead for Asia at Aon Plc, said the most immediate impact is on routing, with airlines avoiding restricted or higher‑risk airspace across the Gulf and wider Middle East.

“That often means longer flight times, higher fuel burn and, in some cases, payload restrictions on long‑haul routes,” he said, adding that this reduces aircraft and crew productivity on Europe–Asia and Africa–Asia corridors.

The restrictions stem from conflict and heightened security risk across parts of the Middle East, where airspace has been intermittently closed or reclassified.

Airlines have been forced to avoid restricted airspace and plan around them using notice to air mission (NOTAM) advisories and security assessments.

The Civil Aviation Authority of Singapore issued a safety bulletin in March advising operators to avoid conflict‑affected airspace and prepare alternative routings, citing risks from military activity and navigation interference.

Singapore’s Ministry of Foreign Affairs also issued travel advisories after hostilities escalated, disrupting flights and triggering wider airspace closures.

Blakey said periodic closures have made airline networks harder to manage, with carriers bearing most of the cost. Insurers and brokers are tracking aircraft movements and exposure across airports and regions rather than changing core cover. Those pressures are filtering into Singapore’s aviation insurance market, particularly war risk and political violence cover.

Rudman said insurers are applying route‑by‑route assessments and, in some cases, sub‑limits or tighter terms for operations closer to conflict zones. “We have seen upward pressure on war‑risk premiums,” he said in an emailed reply to questions.

Blakey said insurers are focusing on where and how airlines fly rather than changing cover for aircraft damage or third‑party claims. “Underwriters may ask more detailed questions on routing, security procedures, and accumulation controls,” he said in a separate email.

Pricing is based on expected risk. Rudman said higher war risk premiums are likely to stay for airlines flying near or through the Middle East until tensions ease.

Insurers and brokers are adjusting cover based on how well airlines manage routing, security and planning, Rudman said. “In some cases, there is interest in tailored solutions such as selective use of captives or parametric structures to manage the financial impact of sudden airspace closures or route suspensions,” he added.

Blakey said insurers could cap payouts or charge more for flights into higher‑risk areas. He added that airlines are using real‑time data to adjust routes, fuel loads, and alternates.

Rudman said modern platforms combine NOTAMs, airspace data, weather, and security inputs with dashboards that track fleets, crews, and airport conditions.
