Aviation War Risk Reinsurance
The January Renewal Cycle
Primary aviation war risk underwriters lay off a portion of their exposure to reinsurers. Most aviation reinsurance renews on 1 January, making the late-year reinsurance negotiations the single most important pricing signal for the following year. This page summarises the 2023–2026 cycle dynamics.
How the Renewal Cycle Works
Reinsurance negotiations for 1 January renewal begin in Q3 of the preceding year. Reinsurers review loss history, portfolio composition, and current geopolitical exposure. They offer renewed capacity with updated pricing, attachment points, and exclusions. Primary underwriters then adjust their own pricing to reflect their reinsurance costs. Those costs propagate to airlines through premium quotes across the following year.
When reinsurance hardens, primary underwriters have two choices: charge more, or retain more. Both result in primary airline war risk premiums rising.
2023 – 2026 Cycle Summary
| Renewal | Reinsurance tone | Primary premium effect |
|---|---|---|
| 1 Jan 2023 | Materially harder post-Russia claims emergence | +30–100% by exposure |
| 1 Jan 2024 | Remained hard; selective capacity withdrawal | Stable to +20% |
| 1 Jan 2025 | Stabilisation on non-conflict exposure; conflict exposure still hard | Mixed by geography |
| 1 Jan 2026 | Post-Oct 2023 / Middle East events absorbed | Stable broad portfolio, elevated for Gulf / Ukraine-adjacent |
Why Concentration Matters
Aviation war reinsurance capacity sits with a small number of reinsurers. Changes in their appetite — driven by loss experience, ratings pressure, regulatory capital requirements — propagate quickly through the primary market. Unlike property or general liability reinsurance, there is limited alternative capacity to absorb the shock.
