Jersey and Guernsey Private Wealth: Why Trusted Jurisdictions Matter More in 2026

1. THE DEVELOPMENT

Two developments in the Channel Islands during September provide a useful snapshot of how established international finance centres are positioning themselves in a more complex wealth environment. Jersey Finance’s annual Private Wealth Conference, held in London on 22 September, attracted a record attendance of more than 560 delegates. The discussions focused heavily on trust between generations, geopolitical uncertainty, regulation, family governance and the role of advisers as families deal with increasingly complex international affairs.

Guernsey, meanwhile, published its second-quarter investment statistics on 15 September. Guernsey-domiciled funds held £270 billion of net assets at the end of the quarter. Closed-ended funds represented £224.2 billion of that total, while open-ended funds rose 5.1% during the quarter to £45.8 billion. The figures show a mature private-capital centre that remains heavily weighted towards closed-ended structures used across areas including private equity, infrastructure, property and other long-term strategies.

2. THE PRIVATE WEALTH CONTEXT

The relevance of Jersey and Guernsey is often misunderstood. They are sometimes discussed simply as “offshore” jurisdictions, but that description says very little about what sophisticated international families actually use them for. Their financial sectors encompass trusts, companies, funds, banking, fiduciary services and investment structures designed to operate across multiple countries.

For private wealth, the important concept is governance. A family may have beneficiaries in several countries, operating companies elsewhere, investment portfolios held at international banks and assets intended to pass between generations. The purpose of a well-designed structure is to create a coherent legal and administrative framework around those different interests. Jurisdictions such as Jersey and Guernsey compete in that market on legal certainty, professional infrastructure, regulation and the depth of their fiduciary sectors.

The same principle applies to private capital. Guernsey’s fund industry is predominantly closed-ended. A closed-ended fund normally raises committed capital for a defined period rather than allowing investors to withdraw money on demand. That model is particularly suited to assets that themselves take time to realise, such as private businesses, infrastructure or private-credit investments.

Jersey’s conference also highlighted a change taking place within family wealth. Succession is increasingly being treated not simply as the legal transfer of assets but as a governance question: who understands the wealth, who is prepared to manage it, how decisions are made and what happens when different generations have different objectives. Jersey Finance’s own conference discussions stressed that the next generation needs responsibility as well as inheritance.

3. WHY THIS MATTERS FOR CAPITAL

As wealth becomes more international, the quality of the jurisdiction surrounding a structure can influence far more than tax. Banks, lenders, trustees, investment managers and counterparties all need to understand ownership, control, source of wealth and the purpose of a structure. A well-established jurisdiction with experienced professional providers can therefore support bankability, governance and continuity. Conversely, an unnecessarily complicated structure can create additional KYC work, increase costs and make banking or financing more difficult regardless of any theoretical planning advantage.

4. WHAT WE ARE WATCHING NEXT

Over the next six months, the relevant question is whether the renewed focus on geopolitical resilience translates into more demand for established cross-border governance structures rather than simply changes in asset allocation. Internationally mobile families increasingly have to consider where companies, trusts and investment vehicles are administered alongside where individual family members live.

Over twelve to twenty-four months, substance is likely to remain central. Structures must increasingly have a clear commercial or family purpose, appropriate governance and credible administration. The direction of travel among reputable international finance centres is consequently towards greater professionalism and transparency rather than secrecy.

For private capital, Guernsey’s next fund statistics will also be worth following. The current data show broadly stable total assets over the year but different trends beneath the surface, with the open-ended sector growing while the much larger closed-ended segment declined modestly.

5. HOW PROFESSIONAL CAPITAL IS RESPONDING

Family offices and professional advisers are increasingly treating jurisdictional selection as part of risk management rather than as an isolated tax exercise. The Jersey conference’s emphasis on trust, reputation, regulation and geopolitical uncertainty reflects that broader change. According to Jersey Finance, the 2026 event was its best-attended private wealth conference to date, suggesting substantial professional interest in those questions, although conference attendance should not itself be interpreted as a measure of capital flows.

Guernsey’s £270 billion fund sector provides a different but complementary signal. Institutional and private-market capital continues to use the island for long-term investment structures despite a modest quarterly decline in overall net assets. The significance is less the movement of one quarter than the scale of the infrastructure already supporting private-market assets.

6. THE PRIVATE BANKING PERSPECTIVE

A private banker looking at an international family should begin with the family’s economic reality rather than with a jurisdiction. Where do the businesses operate? Where are family members resident? Where are the assets custodied? Which generation controls them? Is there borrowing against those assets? Who will eventually inherit them? Only once those questions are understood does it make sense to determine whether a Jersey trust, Guernsey company, Swiss banking relationship or another structure has a legitimate role.

That matters because banks increasingly assess the entire ownership chain. The most sophisticated structure in legal terms is of little use if every new bank relationship requires months of explanation or if a lender cannot understand where collateral sits and who ultimately controls it. Private wealth architecture must therefore be legally sound, operationally manageable and bankable at the same time.

7. IMPLICATIONS FOR INTERNATIONAL CLIENTS

For Sutterson Reed’s international clients, Jersey and Guernsey can be particularly relevant where banking, family governance, investment holdings and succession cross several jurisdictions. They should not be viewed as default solutions or as jurisdictions reserved for British families. A Greek entrepreneur with international investments, a Gulf-based family holding European assets or an Asian family using Swiss banks can all face the same underlying challenge: creating a structure that remains understandable and functional across borders.

8. THE PRIVATE OFFICE VIEW

The renewed attention being paid to Jersey and Guernsey reflects a broader shift in international wealth. In an environment shaped by geopolitical uncertainty, regulatory scrutiny and increasingly mobile families, sophisticated clients are placing greater value on structures that can withstand change rather than simply optimise for the present moment. The role of the Private Office is therefore not to accumulate jurisdictions, banks or entities, but to ensure that each element of the structure serves a clear purpose and that the whole remains coherent.
