Jersey’s private wealth markets have always been more global in character than local. The clients who book here are typically international, often multi-generational and the pressures of 2026 have made their mobility more pronounced.
The UK’s non-dom reforms have accelerated a pattern already visible before the Autumn Budget: wealthy individuals restructuring their affairs, in some cases relocating entirely, and in many cases maintaining their Channel Islands banking relationships regardless of where they are personally resident.

Trends in 2026
Managing volatility
Grant Hamilton of UBS notes that 90 per cent of client conversations this year have centred on managing volatility and market uncertainty. The advisers who have handled this best tend to share a particular quality: they were prepared. Hamilton divides clients into those who could look past the noise and stay invested, those who had liquidity set aside and used market dips as an opportunity, and those who needed more education and historical context to feel comfortable. The conversation, he says, is as much about reassurance as returns.

Allan Stewart of Oakglen Wealth takes a deliberately benchmark-aware rather than benchmark-constrained approach, designed to manage drawdowns while still capturing the majority of market upside. Mark Clubb of TEAM Asset Management describes the underlying philosophy similarly: ‘We have an outstanding long-term track record, particularly in volatile markets, and we have a hard-wired, disciplined investment process.’

The relationship imperative
In a market shaped by trust company introductions and multi-generational family relationships, the quality of the client relationship remains the central differentiator. Thomas Cummins of UBP is direct about what this means in practice: ‘Here’s my mobile number, it doesn’t matter what time it is, you call because we’ll be there for you.’ When something goes wrong, the instinct is the same: ‘The first thing to do is get on the phone to the client and say, look, we’ve got a bit of an issue here, but I’m dealing with it.’

Cameron Walker of Nedbank Private Wealth articulates a similar priority: ‘We ask good questions, we make sure people feel comfortable with who we are, what we do and the advice that we give is then delivered in a trusted and well-supported environment.’ Jonathan Giles of Rathbones, whose clients range from locally based UHNW individuals to international families introduced through intermediaries, focuses on capital protection as the foundation, with client relationships reviewed at least annually and more frequently when trigger events arise.

Methodology
Each year, the Spear’s Research Unit reassesses and refreshes its rankings of the leading providers in each sector by gathering data from and about the advisers and firms themselves, assessing submission forms, collating nominations, carrying out peer reviews, reviewing data from third-party sources, gathering references and recommendations, canvassing experts and conducting hundreds of interviews.
Advisers are evaluated using a proprietary scoring system that assigns different weightings to certain attributes. These scores feed directly into each new set of rankings in the Spear’s Indices. Each of these indices are published first online (according to the research calendar) and then in print. Print publication takes the form of the annual Spear’s 500 directory, which includes the top advisers in every index.

Best wealth managers in Jersey: some names to know
Thomas Cummins
- Focus: International clients
- Ranking: Top Recommended
- Firm: UBP
Thomas Cummins, head of private banking at UBP in the Channel Islands, has spent his career going where others haven’t. When his boss asked if anyone wanted to cover Africa early in his career, Cummins was the one who put his hand up. ‘I’ve never been afraid to look at new markets, new areas and challenges,’ he says.
That instinct has shaped a practice that now spans Jersey and Hong Kong, with Singapore and Kuala Lumpur in his sights. Following UBP’s acquisition of Kleinwort Hambros, his role has refocused on direct client work – where, by his own admission, his strengths lie.
His philosophy is disarmingly simple. ‘People buy into people, not businesses,’ he tells Spear’s. ‘If a client’s going to give you 100 million, they need to trust you.’ For Cummins, that trust is built through honesty, availability and getting to the phone first when something goes wrong.

Grant Hamilton
- Focus: UHNW trusts
- Ranking: Top Recommended
- Firm: UBS
Grant Hamilton has spent the better part of three decades building a standout wealth management practice in Jersey, having held roles at Merrill Lynch, 7IM, Schroders and Rathbones before joining UBS as an executive director in 2024.
The move was deliberate. He tells Spear’s that he was looking for a firm that could ‘do the whole piece for clients, from banking, lending and investment management to discretionary advisory’, as well as provide access to private markets and specialist hedge funds.
It is a proposition that suits Jersey’s evolving wealth landscape, where trust mandates are growing larger and more complex, and where the influx of internationally mobile clients demands serious institutional capability.

Cameron Walker
- Focus: Holistic client services
- Ranking: Top Recommended
- Firm: Nedbank Private Wealth
For Cameron Walker, Nedbank Private Wealth is, above all, a ‘people-driven business’.
‘We ask good questions; we make sure people feel comfortable with who we are [as providers] and what we do. The advice we give is then tailored and delivered in a trusted and supported environment,’ he tells Spear’s.
Head of private banking for Nedbank’s Jersey operations, Walker has nearly three decades of experience in private banking and wealth management, having joined Nedbank in 2002 after four years as a private banker at SG Hambros. Today, he works with clients who have a UK nexus but with international concerns, from multigenerational wealth holders to entrepreneurs.
