FCA Authorisation to Manage an Offshore Crypto Fund from the United Kingdom

Whether a London based manager needs FCA authorisation to manage an offshore crypto fund turns on what is performed in the United Kingdom, not where the fund is registered. A Cayman Islands segregated portfolio does not sit outside the United Kingdom perimeter because it is Cayman property, and the tokens it holds do not settle the question either. Three operating models resolve the position: appointed representative of an authorised host, a United Kingdom alternative investment fund manager permission, and a United Kingdom entity advising a Cayman operator on a non-discretionary basis. They differ in who holds the permission, who answers to the regulator and how much discretion the manager keeps. Marketing the fund to United Kingdom investors is a separate question with a separate answer. Positions below are stated as at August 2026 and sourced to the FCA's Handbook and published materials.

The error we see most often is a manager who has satisfied themselves that their tokens sit outside the regulated asset perimeter, and concluded that their London activity sits outside it too. Those are two different perimeters, and only one is about the assets.David Lloyd, Chief Executive Officer at CV5 Capital

Executive Summary

The management question and the marketing question sit in different parts of the FCA Handbook, and answering one does not answer the other. This page addresses the first: what conduct performed from London amounts to managing, and so requires permission.

• Managing an alternative investment fund is a regulated activity attaching to conduct in the United Kingdom, and Cayman domicile does not remove it.
• Token classification governs a different perimeter, so unregulated tokens can still sit inside a regulated fund management activity.
• An appointed representative arrangement moves regulatory responsibility to the principal, but does not reach activities outside the prescribed scope.
• A small authorised United Kingdom alternative investment fund manager sits below the FCA's thresholds and carries a reduced but real set of obligations.
• A non-discretionary advisory model works only where decisions are genuinely taken offshore and the operator can evidence it.

When FCA Authorisation Is Required to Manage an Offshore Crypto Fund

Authorisation is required where a person carries on a regulated activity by way of business in the United Kingdom. For a fund manager, two activities do the work: managing an alternative investment fund, and managing investments. The FCA's Perimeter Guidance manual, at PERG 16, starts the analysis with the entity performing the management function, not the place the fund is established.

A Cayman Islands company or segregated portfolio that raises capital from a number of investors and deploys it under a defined investment policy will ordinarily meet the definition of an alternative investment fund. Where a United Kingdom entity performs portfolio or risk management for it, that entity performs the function the regime attaches to, wherever the fund sits.

The second activity, managing investments, is narrower. It bites where a person exercises discretion over assets that are specified investments. A portfolio of unregulated tokens may fall outside it, but that does not place the manager outside the perimeter, because the fund analysis runs independently of what the fund holds.

What Counts as Managing a Cayman Fund from the United Kingdom

Discretion, and where it is genuinely exercised

The regulator's interest is in substance rather than in how an agreement is labelled. Where a portfolio decision is formed, sized and instructed from London, calling that entity an adviser in the fund documents does not change what is performed. The FCA's perimeter guidance is drafted around conduct, and the location of the account or venue is not the operative fact.

This matters more in digital asset strategies, where execution is often continuous and machine driven. A systematic strategy whose parameters are set and adjusted from London is managed from London, even where orders reach venues through infrastructure hosted elsewhere.

Arranging, advising and the line between them

Arranging deals in investments and advising on investments are separate regulated activities, and both attach to specified investments, so a strategy trading only unregulated tokens may not engage either. Where the team also trades derivatives referencing digital assets, or security tokens, the analysis should be run again for each instrument class.

The Three Routes, and What Each One Solves

Route one: appointed representative of an authorised host

In an appointed representative arrangement, an authorised firm accepts responsibility in writing for the regulated activities of an unauthorised firm. The FCA Handbook governs it at SUP 12, setting out the principal's obligations to assess, contract with, supervise and report on its appointed representatives. The FCA tightened those obligations in its 2022 policy statement on the regime.

The route solves speed and cost. The manager does not apply for its own permission, build a compliance function to the standard the FCA expects of an applicant, or hold regulatory capital. What it does not solve is scope: an appointed representative may carry on only prescribed activities, and only where the principal holds that permission.

Discretionary portfolio management does not sit comfortably in that range. Host arrangements are therefore usually built the other way round, with the authorised firm appointed as the fund's manager and the team beneath it. The principal carries regulatory responsibility and can withdraw the arrangement.

Route two: a small authorised or full scope United Kingdom AIFM permission

The second route is for the United Kingdom entity to hold its own permission to manage an alternative investment fund. The FCA Handbook divides managers by size. A full scope firm sits above the thresholds and takes the complete set of obligations. Below them, a firm managing an unauthorised fund of this kind is a small authorised United Kingdom manager.

The thresholds are set by reference to assets under management calculated in accordance with the FCA Handbook. The lower limit applies where the funds employ leverage, and a higher limit where they are unleveraged and carry no redemption rights exercisable in the first five years from initial investment. Strategies using perpetual futures, margin or borrowed stablecoins should assume the leveraged calculation applies.

The small authorised position is frequently misread as a light registration. It is not. The firm is authorised, must satisfy the FCA at application on its people, systems and financial resources, reports periodically under FUND 3.4 and meets the own funds requirement in IPRU-INV Chapter 11.

Route three: a United Kingdom entity advising a Cayman operator

The third route places the management function outside the United Kingdom. A Cayman Islands entity is appointed as investment manager and takes the decisions, while a United Kingdom entity provides research and non-discretionary recommendations under a services agreement, holding no discretion and unable to instruct trades.

The route is real and is used. It fails when it is a description, not a fact. If the London team decides and the offshore entity confirms, the function is performed in the United Kingdom whatever the agreements say. The operator needs people who can decline a recommendation, a documented process and decision records.

That capability is not costless. It requires a Cayman manager entity as the operator with real personnel and governance, and must withstand substance where the manager entity sits. A Cayman entity conducting securities investment business also has its own analysis under the Securities Investment Business Act, which produces a registration, not a licence.

Comparing the Routes on Responsibility, Discretion and Time

The three routes are mutually exclusive operating models, not sequential steps. The answer follows from facts the manager already knows: where the decision is formed, how much discretion can be given up, and how long the launch window is.

Marketing Into the United Kingdom Is a Separate Question

Managing the fund and offering it to United Kingdom investors are governed separately, and resolving the first does not resolve the second. The FCA Handbook addresses marketing by managers outside the United Kingdom at FUND 10, and regulation 59 of the Alternative Investment Fund Managers Regulations 2013 sets the notification required before such a fund is marketed to United Kingdom investors. That route was inherited from Article 42 of the Alternative Investment Fund Managers Directive.

Separately, any communication inviting investment engages the financial promotion restriction, and the FCA's conduct rules in COBS 4 constrain to whom interests in an unregulated pooled vehicle may be promoted. A manager can sit outside the management perimeter and still breach those rules.

This page answers the authorisation and permission question. The companion guide to marketing a Cayman fund into the United Kingdom answers the marketing question, covering the notification regime, its conditions and its reporting consequences. The general treatment for United Kingdom managers of Cayman hedge funds shows how both interact across a launch.

Reform, and What It Does Not Change

The regime applying to United Kingdom alternative investment fund managers is under reform. The FCA has published consultation and policy work on replacing the framework the United Kingdom inherited, including the treatment of firms below the current thresholds. As at August 2026, managers should plan against the rules currently in the FCA Handbook and track the regulator's own published output.

A manager choosing between a small authorised permission and a host arrangement should ask how each behaves if the threshold architecture changes, because a permission is easier to adjust than a dependency on another firm. Reform of the manager regime does not alter the Cayman analysis, so fund domicile is a separate decision that should not be reopened because a United Kingdom rule moves.

Managers with European investors should run the analysis twice, because the European position moved on its own timetable and a conclusion under one regime cannot be carried into the other.

Consequences for the Management Agreement, Delegation and Reporting

The route chosen has direct drafting consequences. The investment management agreement must be with the entity that lawfully performs the function, so where a host firm is appointed the manager's own entity appears as a delegate rather than the fund's manager. Fee flows, termination rights and liability provisions follow it, and the offering document must describe the structure as it operates.

Delegation is separately regulated. The FCA Handbook at FUND 3.10 governs delegation by a full scope firm, including notification and the prohibition on delegating so extensively that the firm becomes a letter box entity. A small authorised firm is subject to the FCA's outsourcing requirements in SYSC. In both cases the regulator asks whether the firm can still supervise the delegate.

Reporting differs too. A full scope firm carries pre-investment disclosure and annual reporting duties under FUND 3.2 and FUND 3.3 alongside periodic reporting. A small authorised firm carries the periodic obligation under FUND 3.4 without the full disclosure architecture. Allocators ask for the report itself, so structuring the United Kingdom manager entity should account for who produces it.

Key Takeaways

• Record where each investment decision is formed and who can change risk limits, then run the activity test on those facts before choosing a model.
• If a host arrangement is used, confirm in writing that the strategy sits inside the principal's permission.
• If a permission is sought, model headroom against the leveraged threshold and apply before a launch date is given to investors.
• If the offshore advisory model is used, build the operator's decision making capability and records first, as a governance project rather than a drafting exercise.
• Resolve the marketing perimeter separately before any United Kingdom investor is approached.

Frequently Asked Questions

Do I need FCA authorisation to manage a Cayman crypto fund from London?

It depends on what is performed in the United Kingdom. If a United Kingdom entity performs portfolio or risk management for the fund, it performs the function the alternative investment fund manager regime attaches to, and Cayman domicile does not remove that. The FCA sets out the analysis at PERG 16.

My fund only holds unregulated tokens, so am I outside the perimeter?

Not necessarily. Token classification governs whether activities such as managing investments and advising on investments are engaged. It does not answer whether managing the pooled vehicle is a regulated activity, which is assessed under the fund manager rules irrespective of the assets held.

What is a small authorised United Kingdom AIFM?

It is a firm managing alternative investment funds below the thresholds the FCA Handbook sets, authorised with a reduced set of obligations. It is an authorisation, not a registration, so the firm must satisfy threshold conditions, meet the IPRU-INV Chapter 11 own funds requirement and report under FUND 3.4.

Can I appoint a Cayman investment manager and keep my team in London?

Only where investment decisions are genuinely taken by the Cayman entity, which needs people able to decline recommendations, a documented process and records of where decisions were made. If the London team decides in practice, the function is performed in the United Kingdom regardless of the agreements.

Is the United Kingdom regime for fund managers changing?

The framework is under reform and the FCA has published consultation and policy work on replacing it, including the position of firms below the current thresholds. As at August 2026 the rules in the FCA Handbook continue to apply.
