UK Managers and Cayman Hedge Funds: Why London-Based Teams Still Use Offshore Fund Structures

London remains one of the world's most important hedge fund manager hubs. Cayman remains one of the world's most familiar offshore fund jurisdictions. The persistence of both, as the predominant pairing for institutional hedge funds, is not an accident. The two jurisdictions answer different questions: London is where the investment manager operates, holds its FCA permissions and employs its team, and Cayman is where the fund itself is structured under a framework that international allocators have spent decades diligencing. A Cayman fund for UK managers is the offshore vehicle that supports global capital raising without disrupting the manager's London operating model, and the structure has continued to dominate UK fund launches because the underlying logic has not changed.

"London managers occasionally ask whether the offshore model still makes sense in 2026. The answer, for most of the institutional managers we work with, is that it still makes sense for the same reasons it always has. The manager domicile and the fund domicile are separate decisions answering separate questions. FCA authorisation, financial promotion compliance and the UK tax position of the manager are matters for the London operating entity. The fund structure that global allocators apply their existing diligence framework to is a matter for the offshore vehicle. Cayman has not displaced London. It has continued to support it." David Lloyd, Chief Executive Officer of CV5 Capital

Why London Managers Use Offshore Funds

The UK hedge fund ecosystem supports a wide range of strategies, from global macro, long short equity, credit, event driven, statistical arbitrage, systematic and multi strategy through to the growing digital asset manager community based in and around London. The investor bases these managers raise from are predominantly international: US endowments and foundations, US family offices, Middle Eastern sovereigns, Asian institutional allocators, European institutional capital, multi manager platforms and global fund of funds. The proportion of capital that comes from purely UK domiciled sources is, for most institutional London managers, a smaller share of the book than international observers might assume.

Cayman has remained the predominant fund domicile for this international capital raising because the regulatory framework, the offering documentation conventions and the service provider ecosystem are universally familiar to the diligence teams of the allocators concerned. The same allocators evaluating a London manager's strategy expect to see a Cayman fund structure. A UK domiciled fund vehicle is a viable choice in some circumstances and is used by certain UK manager and investor combinations, but as the default offshore wrapper for institutional capital raising, Cayman has continued to occupy the position it has held for thirty years. The detail behind the framework is set out in our reference on the key considerations when setting up a Cayman fund, and the Cayman master feeder structures for traditional managers reference covers the architecture most UK launches actually use.

How the UK Manager and Cayman Fund Model Works

The FCA authorised investment manager is appointed to the Cayman fund under an investment management agreement, with the fund itself governed by its Cayman board. The London team conducts investment decision making under the regulatory framework that applies to the UK entity, including the conduct of business rules, the financial promotion regime and the conduct expectations of FCA authorisation. The Cayman fund holds the strategy, accepts subscriptions from the international investor base and operates through the institutional service provider arrangements approved by its board. The two entities are connected commercially through the investment management agreement, but they are separately governed under separate regulatory regimes for separate reasons. The economic logic is examined in our pieces on how managers control the strategy rather than the assets and on the platform fund model under which managers retain brand, IP and track record.

Master-Feeder Structures and the Offshore Feeder

For managers with both US and non US investors, the institutional pattern is a master feeder structure. The master fund, typically a Cayman entity, holds the trading book and is the operational centre of the strategy. The feeders subscribe into the master and offer differentiated terms to different investor bases. The US taxable feeder, frequently a Delaware limited partnership, accommodates US taxable investors. The offshore feeder, typically a Cayman exempted company, accommodates US tax exempt investors and non US investors. This architecture has been used by London managers for decades because it allows a single trading strategy to serve a global investor base without forcing the manager to operate two strategies for tax structuring reasons.

The economics of master feeder structures, particularly the relative cost of standalone master feeder set up against the available alternatives, are addressed in more depth in our companion article on launching a master feeder fund under the CV5 Capital umbrella, with the architectural detail covered in Cayman master feeder structures explained for traditional managers. For UK managers, the principal point is that the master feeder is a well established pattern, supports the global investor base typical of London hedge fund launches, and continues to be the default architecture for strategies that need to accept both US taxable and non US capital.

What Allocators Expect From a UK-Managed Cayman Fund

Operational due diligence on a UK managed Cayman fund applies the standard institutional framework, with additional focus on the cross border architecture and the UK regulatory disclosures. Allocators conducting ODD on a London managed Cayman fund are typically familiar with the model, and the diligence cycle moves quickly when the fund's documentation, governance and service providers conform to institutional expectations.

The FCA and UK Tax Layer

UK managers launching a Cayman fund retain their FCA permissions and the regulatory obligations that apply to the London operating entity. The financial promotion regime, the conduct of business rules, the senior managers regime, the regulatory reporting cadence and any AIFMD related considerations applicable to UK managers operating in the EU continue to apply on their existing terms. The UK tax position of the manager, the personal tax position of the principals and any tax treatment of carried interest or performance fees flowing back to the UK are matters for the manager's UK tax advisers. The institutional approach is to coordinate the UK regulatory and tax workstream with the Cayman fund formation workstream so that both are resolved by the time the fund accepts its first subscription.

Frequently Asked Questions

Key Takeaways

• London remains a leading hedge fund manager hub. Cayman remains the predominant offshore fund domicile. Most institutional UK launches pair the two as a matter of standard practice.
• The FCA authorised manager remains in London, holding its permissions and operating under the UK regulatory framework. The Cayman fund is governed by its board and operated through an institutional service provider stack.
• Master feeder structures are the default architecture for UK managers raising from both US taxable and non US investors. The master sits in Cayman, the US taxable feeder in Delaware and the offshore feeder in Cayman.
• Operational due diligence on a UK managed Cayman fund focuses on the FCA permissions, the investment management agreement, the board, the administrator, the financial promotion arrangements and the integrity of the cross border architecture.
• FCA authorisation, financial promotion compliance, the senior managers regime and the UK tax position remain with the manager's London operating entity. The Cayman fund formation runs in parallel without disturbing them.
• The platform model compresses the Cayman side of a UK manager's launch. The regulatory umbrella, the governance, the service providers and the operational policies are in place from day one.
