Bermuda, cayman vie as life reinsurance booms past $90b

The life and annuity reinsurance market has witnessed a remarkable surge in reserves ceded to sidecars, escalating from $55 billion in 2023 to over $90 billion by 2025. This rapid growth is largely fueled by robust U.S. annuity sales combined with rising interest rates, which have intensified insurers' demand for additional reinsurance capacity to manage capital requirements and secure surplus relief through reinsurance leverage. Notably, sidecar structures, once predominantly a property/casualty tool, have gained significant traction in life and annuity since 2021, with transactions spanning new business and third-party blocks, including notable activity in markets like Japan.

Bermuda continues to dominate as the premier hub for life and annuity sidecars, capturing 40.7% of all ceded U.S. life and annuity liabilities—equating to $1.1 trillion out of $2.7 trillion ceded globally by year-end 2025. This leadership stems from its supportive regulatory framework and the rise of newly established Bermuda reinsurers, which have amassed nearly $355 billion in assumed reserves since 2017, with 2025 alone seeing over $73 billion in new transactions. However, emerging domiciles like the Cayman Islands are gaining ground, leveraging innovative funds withheld modco structures to mitigate counterparty risk and enhance risk-based capitalization.

The launch of West Grove Re Ltd., a Bermuda-based sidecar capitalized with approximately $1 billion by Talcott and Goldman Sachs Asset & Wealth Management, exemplifies the infusion of third-party capital and credit facilities into the life and annuity reinsurance space. This structure provides scalable, capital-efficient reinsurance capacity tailored to the booming U.S. annuity market, reflecting a broader trend where insurers seek innovative funding solutions to support new business growth, manage legacy portfolios, and maintain capital flexibility amid a favorable interest rate environment.

Bermuda has firmly entrenched itself as the preeminent global hub for life and annuity reinsurance, capturing over 40% of U.S. ceded liabilities by 2025, amounting to approximately $1.1 trillion of the $2.7 trillion total. This dominance is bolstered by a robust ecosystem of newly established reinsurers and sidecar structures, such as the $1 billion West Grove Re Ltd. launched by Talcott Financial Group and Goldman Sachs, which leverage Bermuda’s favorable regulatory framework and capital market infrastructure to deliver scalable, capital-efficient solutions. The jurisdiction’s leadership extends into insurance-linked securities (ILS), where it accounted for over 93% of global issuances in 2025 and nearly 95% by early 2026, underscoring Bermuda’s unparalleled role in facilitating alternative capital inflows and risk transfer.

While Bermuda maintains its commanding market position, the Cayman Islands are emerging as a noteworthy competitor by strategically aligning their regulatory framework with U.S. standards and investing in ecosystem development to attract life and annuity reinsurance business. The Cayman Islands’ pursuit of U.S. NAIC Qualified Jurisdiction Status (QJS), as emphasized by Premier Andre Ebanks, aims to enhance their appeal in both the ILS and reinsurance markets, foster job creation in actuarial and related fields, and position the jurisdiction for reciprocal regulatory recognition with the U.S. This regulatory alignment and ecosystem investment signal the Cayman Islands’ intent to mature their reinsurance industry and capture a growing share of alternative capital flows, even as Bermuda continues to lead.

Bermuda’s sustained dominance is underpinned not only by its scale but also by its regulatory agility, which provides capital management flexibility and supports new business growth, legacy block management, and access to third-party capital. However, ongoing regulatory developments in both Bermuda and the U.S., including enhanced liquidity testing, broader reporting obligations, and increased scrutiny of affiliated transactions and sidecar structures, are poised to shape the future trajectory of the life and annuity reinsurance market. These measures reflect a maturing market environment where Bermuda’s ability to adapt its regulatory framework will be critical to maintaining its leadership amid rising competition and evolving capital market dynamics.

By mid-2026, innovative capital solutions such as the $1 billion Bermuda-based West Grove Re sidecar, launched through a partnership between Talcott and Goldman Sachs Asset & Wealth Management, exemplify how reinsurance structures are evolving to enhance capital efficiency and scalability in the U.S. annuity market. This sidecar combines equity commitments with a credit facility and leverages Goldman Sachs’ asset management expertise alongside Talcott’s actuarial and risk services, reflecting a broader industry trend of mobilizing third-party capital to fuel insurance growth more efficiently.

Simultaneously, Bermuda is spearheading the modernization of the insurance-linked securities (ILS) market through pioneering efforts in tokenisation, which promises to democratize investor access, streamline settlement processes, and boost secondary market liquidity. The Bermuda Monetary Authority’s proactive regulatory stance balances fostering innovation with maintaining market integrity, particularly by focusing on parametric special purpose insurance and climate-linked products that address emerging risks like wildfires, cyber threats, and severe weather events, thereby expanding ILS beyond traditional natural catastrophe exposures.

The Cayman Islands' strategic pursuit of US NAIC Qualified Jurisdiction Status (QJS) underscores a broader trend of jurisdictional competition and regulatory alignment within the life and annuity reinsurance market. Premier Andre Ebanks highlighted that achieving QJS would not only harmonize Cayman’s reinsurance regulations with US standards but also catalyze organic growth by leveraging synergies with investment funds and private equity sectors, positioning the jurisdiction alongside established hubs like Bermuda. This regulatory ambition aims to mature the local reinsurance industry, enhance competitiveness, and foster sustainable development through specialized job creation in actuarial science, thereby addressing talent retention challenges.

Recent regulatory developments in Bermuda and the U.S. — including enhanced liquidity testing, expanded reporting obligations, rigorous reserve adequacy assessments, and intensified scrutiny of affiliated transactions and sidecar structures — are reshaping the operational landscape for life and annuity reinsurers. According to ALIRT’s August 2026 analysis, these measures are designed to bolster market resilience and transparency, reinforcing Bermuda’s leadership position despite the rise of new reinsurers and strategic partnerships. Meanwhile, the Cayman Islands is emerging as a credible alternative jurisdiction, reflecting a dynamic interplay of regulatory evolution and jurisdictional rivalry that will ultimately influence the market’s scalability and competitive contours.
