Key takeaways
The Thematic Review of Reinsurance Companies issued by the Cayman Islands Monetary Authority ('CIMA') in June 2026 (the 'Review') finds that corporate governance accounts for sixty-eight percent of all weaknesses identified across the Class B(iii) and Class D entities examined. The review covered both life/annuity and P&C reinsurers holding these licence classes, but the governance findings are particularly material for commercial platforms with billion-dollar balance sheets. For those entities, the message to boards is clear: Cayman is aligning its governance expectations with the institutional standards that cedants, their US state regulators, rating agencies, and other key stakeholders already expect from major reinsurers. This is a sign of jurisdictional maturation and a call to action to strengthen documentation, processes, and service-delivery frameworks across the industry.
CIMA examined Class B(iii) and Class D reinsurers (including both life/annuity and P&C business) with fieldwork between mid-2025 and Q1 2026. The findings clustered around governance architecture rather than capital or liquidity concerns. Within the 68% percent governance share, sub-committee governance and board oversight each accounted for 20%; missing service-provider contracts, segregation of duties, and internal audit gaps each accounted for 13%; outdated business plans, meeting discipline, and board self-assessment each accounted for 7%. These patterns align with the governance fundamentals emphasised by the IAIS Insurance Core Principles and the NAIC’s guidance on affiliated investment management agreements.

We recommend that boards and managers use the Thematic Review as an opportunity to assess their reinsurance company's governance and other frameworks against (i) the findings in the review, (ii) CIMA’s RSOGs, and (iii) best practices in the jurisdictions the Cayman reinsurer aims to/does write business:
Thematic reviews conducted by CIMA provide important insights into areas of particular focus for CIMA, which should be part of inspection-readiness. CIMA has previously published thematic reviews on key topics such as corporate governance and outsourcing which help licensees understand CIMA's expectations.
Walkers works closely with clients to help them achieve and sustain institutional grade governance and robust compliance. For boards, managers, and GC functions, the thematic review offers an ideal opportunity to assess whether external legal expertise could enhance your governance structure, internal controls, and other requirements. To explore how the review impacts an existing or planned platform or how you can prepare for upcoming on-site inspections or other thematic reviews, please contact your usual Walkers relationship partner or members of our Insurance & Reinsurance team and Regulatory & Risk Advisory team.
