Definition
A captive reinsurer is a reinsurance company owned by — or affiliated with — the same corporate group as the insurance carrier ceding business to it, used to retain reinsurance economics within the group rather than transferring them to a third party.
Why it matters
Captive reinsurance is the structural arrangement by which an insurance group can manage capital, asset strategy, and tax positioning across affiliated entities while satisfying the statutory and regulatory requirements that apply to reinsurance. In the current US life and annuity market, captive reinsurers are commonly used by private equity-affiliated carriers and by some traditional carriers to operate intra-group reinsurance programs that influence what backs an asset-backed claim and where the assets supporting it are held.
How it works
A captive reinsurer is a licensed reinsurance entity established and owned within an insurance group. The ceding operating carrier transfers some portion of its insurance liabilities — and a corresponding share of premiums and reserves — to the captive reinsurer under a reinsurance treaty. The captive then holds the ceded reserves and supporting assets within its own balance sheet, often domiciled in a jurisdiction with capital, accounting, or tax features different from the ceding carrier's state of domicile (a stylized illustration: a US-domiciled life carrier cedes a block of fixed annuity liabilities to a Bermuda-domiciled captive in the same corporate group; the captive's general account is then managed under the group's investment mandate, with allocations to affiliated private credit and other holdings). The arrangement is governed by the reinsurance treaty, by the holding company act provisions on intra-group transactions in the ceding carrier's state of domicile, and by the regulatory framework of the captive's domicile.
In practice
Captive reinsurers do not appear directly in any individual annuity contract, but their existence and structure affect what backs the contract. An individual evaluating an annuity from a carrier that uses an affiliated captive can ask three structural questions: what proportion of the carrier's liabilities is ceded to affiliated reinsurers and where those reinsurers are domiciled, how the captive's reserves are invested (including the extent of related-party and alternative-asset holdings), and how the financial-strength rating of the ceding carrier treats the captive arrangement. Statutory financial statements disclose the existence and identity of affiliated reinsurance counterparties, though the detail varies by jurisdiction. For fiduciaries evaluating in-plan annuity options, the captive question is part of carrier-level due diligence on the structural backing of the proposed asset-backed claim.
In the Longevity Standard Framework
Captive reinsurer is supporting vocabulary in the Longevity Standard framework, describing the structural mechanism by which intra-group reinsurance, related-party investment, and offshore domiciliation are typically operationalized within a single corporate group. Use of an affiliated captive does not change the four-property characterization of the asset-backed claim the operating carrier issues — risk sharing remains transferred, and cost structure remains embedded spread — but it does change where the assets supporting that claim are held, what they consist of, and which regulatory framework governs their treatment. The captive arrangement is one of the observable structural features used to evaluate the cost-structure economics of asset-backed claims and the counterparty risk profile of the ceding carrier.
