Captive Insurance Structures in Bermuda

The article examines the Bermudian captive insurance model as a tool for corporate risk financing under challenging market conditions and amid the convergence of prudential standards. The relevance of the study is driven by the growth of cascading risks and by the practical dilemma between supervisory harmonization (the Solvency II/International Association of Insurance Supervisors logic) and business demand for proportionate regimes that prevent trapped capital in captives. The purpose of this research is to provide a systematic analysis of captive structures in Bermuda by comparing their regulatory architecture with Solvency II and US risk-based capital, and by identifying factors that enhance capital efficiency. The novelty lies in a comprehensive examination of the bifurcation of the Bermudian regime (Solvency II equivalence for the commercial sector alongside a separate pragmatic framework for captives), in a detailed reconstruction of Bermuda Solvency Capital Requirement/Economic Balance Sheet mechanics based on Bermuda Monetary Authority technical materials, and in introducing an analysis of innovative classes (including digital insurers and the practice of Bitcoin denomination of reserves), as well as the legal construct of Incorporated Segregated Accounts Company as an enhanced form of risk segregation. The findings show that Bermuda’s approach makes capital requirements clearer and more closely tied to the risks a company actually takes. However, the reported solvency metrics can move more with market conditions. Bermuda stays competitive because it allows captives to lower their total cost of risk by retaining underwriting profits, earning investment income on reserves, and buying reinsurance more directly. New frameworks such as Incorporated Segregated Accounts Companies and the regulatory sandbox also support the development of new products and technologies in insurance. The article will be constructive for Chief Financial Officers, risk managers, actuaries, regulators, and consultants who work with captives and capital optimization.
