Kroll Bond Rating Agency (KBRA) has assigned an A- insurance financial strength rating to Malibu Life Reinsurance SP 1, a Cayman segregated portfolio of Malibu Life Reinsurance SPC. The rated entity was established to support a single life reinsurance counterparty, and the outlook is stable.
Malibu Life Re SP1 began operating under its founding reinsurance treaty in May 2024. At the time of assessment, it had accumulated just over a year of operating history.
Malibu Life Re SP1 is not a separate legal entity. KBRA, therefore, did not anchor its analysis on full legal-entity status or solely on Cayman SPC enabling legislation. Instead, the agency relied on the executed reinsurance and collateral trust agreements, supplemented by the segregated portfolio's own capital position, legal frameworks and external support.
The structure uses a funds withheld treaty. Reserve-supporting assets remain legally owned and controlled by the cedant, while the economics accrue to Malibu Life Re SP1. A related trust account provides a collateral layer with monthly valuation and top-up mechanics tied to ceded reserves.
KBRA cited capitalisation as a supporting factor. Year-end 2025 ACL risk-based capital stood at 754%, based on a reported CAL RBC of 377%. That figure was materially above both the entity's internal target and its 500% ACL RBC minimum regulatory requirement.
At year-end 2025, 92% of invested assets were in investment-grade fixed income securities. Net spread earnings reached 109 basis points in 2025. KBRA said that figure was reasonable for an asset-intensive reinsurer in its early years but did not yet represent a stable multi-period earnings pattern.
Malibu Life Re SP1 is owned by Malibu Life Holdings Limited (LSE: MLHL), a London-listed life and annuity holding company. MLHL was formed through the September 2025 combination of Third Point Investors Limited and Malibu Life Reinsurance SPC. During 2025, MLHL made a US$46 million capital contribution to Malibu Life Re SP1 to support continued growth.
MLHL has set a target of approximately US$5 billion in annual premiums by end-2027, with a mid-teens return on equity. The platform aims to grow by originating further annuity reinsurance contracts backed by Third Point's credit investment capabilities.
The agency flagged several constraints. Malibu Life Re SP1 was established to serve a single counterparty under one treaty, a concentrated profile by design. Its enterprise risk, governance and internal control frameworks are new, rely on outsourced service providers and have not been tested through a market cycle.
Structural limitations of the SPC model also apply. Cayman law permits asset and liability segregation but limits fungibility between portfolios and may present legal recognition uncertainty outside the jurisdiction. Cayman reinsurance assets reached approximately US$101 billion at end-2025, up from US$23 billion in 2020. That pace of growth has drawn scrutiny from credit analysts and US supervisors.
KBRA said positive rating action could follow sustained spread earnings, capitalisation above regulatory targets and disciplined growth backed by timely capital support from MLHL. Negative action could be triggered by capital deterioration, operating losses, impairment of investment quality, or a treaty suspension or recapture event.
