The Cayman Islands Monetary Authority (CIMA) has published its 2026 Thematic Review of Reinsurance Companies (Thematic Review). This reflects fieldwork conducted by CIMA between mid-2025 and Q1 2026 at selected Class B(iii) and Class D licensed reinsurers. The focus being on compliance with the Insurance Act (as revised) and other applicable legislation, regulations, rules and statements of guidance as issued by CIMA centering around stress-testing, cash flow testing frameworks, capital and collateral adequacy management, and corporate governance.

Corporate governance weaknesses account for 68% of all findings with the remaining 32% spread across stress-testing, cash flow testing capital and collateral adequacy. Notwithstanding these findings, CIMA has noted several good practices across all areas including, importantly, comprehensive risk management frameworks covering key risk areas and strong capital and collateral adequacy monitoring processes.

With Cayman's reinsurance sector having grown to an institutional scale, and over 110 licensed reinsurers writing in the order of US$30 billion in annual premiums against over US$100 billion in assets, this latest Thematic Review demonstrates development in CIMA's supervisory expectations of Cayman's licensed reinsurers. It represents a reflection of the jurisdiction's increasingly sophisticated and maturing reinsurance market and reinforces that CIMA's expectations align closely with the standards that onshore counterparty cedants, rating agencies and US state regulators already expect.

We take this opportunity to review certain of the key findings alongside CIMA's cross-sectoral 2026 Thematic Review on Outsourcing, note some of the good practices highlighted by CIMA and make some associated recommendations for Cayman reinsurers.

Key Takeaways

• Corporate governance: accounts for 68% of all weaknesses identified — but the remaining 32%, spread across stress-testing, cash flow testing, capital and collateral adequacy, also warrant attention. The above said, a number of good governance practices are also observed and commended.
• Governance documents must reconcile with one another: a licensee's business plan(s), risk framework(s), stress-testing outputs, capital / collateral management policies, outsourcing agreements, and board resolutions effectively comprise (and will be reviewed) as a single body of evidence, not as discrete compliance workstreams.
• Independent review gaps have been identified as a theme: stress-testing and cash flow testing frameworks lacking independent peer review / validation have been flagged as a weakness, even where the frameworks themselves are otherwise well designed.
• Regulatory expectations are rising: This latest Thematic Review demonstrates increased scrutiny of regulatory frameworks with CIMA placing greater emphasis on demonstrating governance and effective...
