Automatic reinsurance refers to treaty structures that apply by default when risk criteria are met, with claims shared according to pre-agreed terms.
Core Function
Instead of negotiating on each policy, automatic treaties define triggers, premiums, exclusions, and settlement terms in advance. It gives the cedant operational consistency and usually faster placement than facultative placement for each risk.
Underwriting and Capital Impact
Underwriters use automatic treaties to manage portfolio-level volatility. For the ceding insurer, this reduces retention burden and stabilizes adverse-event impact. For reinsurers, it creates automatic exposure that must be re-modeled as business grows.
Claims Processing
Claims teams process covered losses in batches against treaty rules. Disputes often involve interpretation of attachment points, limits, timing windows, and whether a line of business qualifies under treaty definitions.
Practical Example
An auto-book insurer writes a stable stream of medium-sized property policies. A sudden weather event triggers several claims across the block. Because the treaty is automatic, the reinsurer receives claim information under the treaty reporting framework and recovers the agreed share without additional underwriting approval at claim time.
