The Cayman Islands is the world’s leading offshore fund domicile, chosen by more than 80% of offshore hedge funds, because it combines institutional recognition, a mature service provider ecosystem, and regulatory credibility that BVI, Bermuda, and Mauritius have not replicated at scale. Each jurisdiction has specific strengths for particular structures, but for managers raising capital from US and UK institutional investors, Cayman remains the default starting point.
The Cayman Islands versus BVI
The British Virgin Islands (BVI) shares a common law legal heritage with the Cayman Islands and offers lower incorporation costs, making it a common choice for holding companies, joint venture vehicles, and smaller structures. For institutional fund managers, however, BVI carries lower recognition among prime brokers and certain categories of investor. Cayman’s deeper pool of specialist fund lawyers, administrators, and auditors means that managers launching against a live capital-raising timeline typically face less friction with a Cayman structure.
The Cayman Islands versus Bermuda
Bermuda has a strong track record in insurance-linked securities, reinsurance vehicles, and certain closed-ended structures, and its legal system offers the same English common law foundation and Privy Council access as Cayman. Ongoing compliance costs in Bermuda are generally higher, and the service provider ecosystem is narrower, which can create operational complexity for managers launching at speed. For hedge funds and private equity vehicles targeting institutional capital, Cayman commands a broader base of counterparty and investor acceptance.
The Cayman Islands versus Mauritius
Mauritius is frequently considered by managers seeking treaty-based access to India and certain African markets, and the jurisdiction has developed a credible regulatory framework under the Financial Services Commission. Structures domiciled in Mauritius carry genuine economic substance requirements and face a different set of due-diligence questions from some institutional investors. For managers whose primary focus is US, European, or global institutional capital rather than treaty-driven market access, Cayman offers a more straightforward path to investor acceptance.
The ecosystem advantage
Beyond regulatory and legal considerations, the Cayman Islands benefits from a concentration of specialist lawyers, fund administrators, auditors, and prime brokerage relationships that has developed over decades. This ecosystem reduces friction at every stage of the fund launch and ongoing operations process. Prime brokers, placement agents, and institutional investors already have established frameworks for Cayman structures, which shortens due-diligence timelines and reduces the volume of legal questions at closing.
The choice of fund domicile is rarely made in isolation, and the right answer depends on the strategy, investor base, and target markets of each manager. wb.group advises fund managers on Cayman entity selection and provides the full range of corporate services to support a fund launch.

Cayman Islands vs BVI, Bermuda, Mauritius Fund Structuring
The Cayman Islands has built a concentration of specialist fund lawyers, administrators, and auditors over decades, and its regulatory framework under the Cayman Islands Monetary Authority (CIMA) is recognised by institutional investors globally. BVI is well-suited to holding company structures and smaller vehicles but does not carry the same level of institutional recognition for open-ended investment funds. The depth of the Cayman service ecosystem also means that fund launches proceed more quickly and with less legal friction.
Bermuda has a stronger track record in insurance-linked securities, catastrophe bonds, and certain closed-ended insurance vehicles, where the Bermuda Stock Exchange and the island’s specialist insurance regulatory framework provide a better fit than Cayman. For hedge funds and traditional private equity structures targeting institutional capital, however, Cayman commands broader prime broker and investor acceptance, and the Cayman service ecosystem is more developed for those asset classes.
Mauritius is most commonly chosen when a manager requires treaty-based access to India under the India-Mauritius double taxation agreement, or when the investment strategy involves markets in sub-Saharan Africa where Mauritius treaties are relevant. Outside those specific use cases, Mauritius requires genuine economic substance and carries a different due-diligence profile with some institutional investors. Managers whose capital base is primarily US or European institutional tend to find Cayman a more straightforward choice.
The Cayman Islands carries higher incorporation and ongoing maintenance costs than BVI, and CIMA registration adds a regulatory layer that smaller structures sometimes seek to avoid. The jurisdiction has also faced periodic scrutiny from organisations such as the EU and FATF, though the Cayman Islands has consistently taken steps to meet international standards and has been removed from relevant lists following remediation. For the majority of institutional fund managers, these factors are outweighed by the benefits of Cayman’s regulatory standing and investor acceptance.
Yes. Many fund structures combine a Cayman Islands vehicle with entities in other jurisdictions. A common pattern is a Cayman Islands Exempted Limited Partnership as the main fund vehicle, with a general partner incorporated in Cayman or another jurisdiction, and parallel vehicles in Luxembourg or Delaware for investors requiring those structures. wb.group supports managers in structuring and administering multi-jurisdictional arrangements from the Cayman Islands end.
