Rapid expansion of offshore reinsurance in the Cayman Islands is creating potential blind spots for US regulators, with $101 billion in assets now supporting life insurance liabilities tied to domestic policyholders, according to a commentary from ThinkAdvisor.
Figures from the Cayman Islands Monetary Authority show reinsurance assets reached about $101 billion at the end of 2025, up from $23 billion in 2020. Licensed reinsurers increased to 113 from 58 over the same period, while total premiums rose to $30.2 billion from $9.3 billion, based on data cited by Cayman Finance.
The scale of offshore activity has drawn attention from US supervisors tasked with monitoring liabilities tied to domestic policyholders. When risks are ceded to affiliated reinsurers outside the US, regulators must determine what liabilities have been transferred, the terms of those agreements, the assets backing them, and how those structures would perform under stress.
Limitations in disclosure or reliance on non-verifiable data can constrain oversight. The issue becomes more pronounced when large volumes of liabilities are supported through offshore affiliates operating under different supervisory frameworks.
This concern is tied to the structure of reinsurance arrangements rather than the function of reinsurance itself, which remains part of insurers’ capital and risk management strategies.
Industry data points to underlying drivers behind the shift. Cayman Finance reports that about 90% of reinsurance business in the jurisdiction originates from the United States and Canada, linking offshore growth to North American insurance demand.
According to reporting from Atlas Magazine and Research and Markets, global reinsurance premiums increased 84% between 2015 and 2024, with the market valued at about $690 billion in 2025. Growth in Cayman has outpaced that trend.
Demand for capital has been influenced by record annuity sales in the US LIMRA reported $434.1 billion in retail annuity sales in 2024, up 13% year over year, with projections exceeding $450 billion for 2025. AM Best data shows the US life and annuity sector’s reinsurance leverage ratio reached 328% at end-2024, compared with about 200% a decade earlier.
Additional reporting from S&P Global indicates that US insurers had ceded more than $1 trillion in liabilities to offshore reinsurers by the end of 2024.
Cayman Finance attributes growth in part to capital flows from asset managers and private equity firms entering the life and annuity space. The jurisdiction’s tax-neutral framework, which does not apply additional taxes on globally sourced premiums or investment returns, has also factored into its use by multinational insurers.
The Cayman Islands’ position as an offshore funds center, with more than 30,000 funds and about $16 trillion in assets, provides access to capital and service providers, according to Cayman Finance.
At the same time, regulatory structures differ from those in the United States. The Cayman framework follows a principles-based, risk-based approach aligned with standards from the International Association of Insurance Supervisors. US regulation is generally more prescriptive.
Existing rules require that all US reinsurance agreements comply with standards set by the National Association of Insurance Commissioners. A minimum of 100% of US statutory reserves linked to these transactions must be held in the United States, either through trusts or asset-withheld arrangements, providing ceding insurers with access to collateral.
Cayman regulators have also been pursuing qualified jurisdiction status with US authorities, which would allow Cayman reinsurers to operate with reduced collateral requirements. Reporting from industry sources indicates that the initiative is part of policy priorities for 2026 and 2027, though no timeline has been confirmed.
Credit analysts have begun to address the implications of offshore activity. Moody's has characterized growth in US life reinsurance activity in the Cayman Islands as a net credit negative, citing counterparty exposure and limited transparency.
Differences in disclosure, capital frameworks and supervisory approaches across jurisdictions contribute to ongoing scrutiny.
Regulatory frameworks developed after the Global Financial Crisis placed emphasis on identifying risks early through group supervision and enterprise risk monitoring. Those principles remain relevant as insurers use cross-border structures to manage liabilities.
US state regulators are positioned to address market volatility, but offshore exposures introduce additional layers that require clear and consistent visibility.
Regulators are expected to ensure they have access to sufficient information on offshore reinsurance exposures tied to US insurers. Addressing gaps while markets remain stable allows for measured responses.
Reinsurance continues to support insurance markets and capital flows. Effective supervision depends on transparency and the ability to verify how policyholder obligations are supported, particularly when those obligations are linked to entities outside the United States.
