Swiss Private Banks: Ranking by AUM, Minimum Deposits for Foreign Clients, and How to Choose

Last reviewed on 28 August 2026.

"Swiss private bank" describes a specific kind of institution: a bank whose core business is managing the wealth of individuals and families, rather than lending, payments or investment banking. Switzerland has several dozen of them, from Pictet and Lombard Odier — Geneva partnerships older than most countries' central banks — to listed groups such as Julius Baer and Vontobel, family-controlled houses such as UBP and Edmond de Rothschild, and small boutiques with a few billion under management. This page ranks the leading Swiss private banks by assets under management, sets out what minimum deposit a foreign client should expect, and explains the differences in ownership and service model that actually matter when choosing one. Profiles of the largest houses are in the bank directory.

Swiss private bank ranking by AUM

Assets under management is the conventional size measure for a private bank. The figures below are rounded from the banks' most recent annual reports and include institutional and fund assets where a bank reports them together; the order among the mid-sized houses shifts with markets each year.

UBS is deliberately excluded: it is the world's largest wealth manager and dominates any Swiss ranking, but it is a universal bank rather than a private bank. It appears in the largest Swiss banks ranking instead. Other well-regarded houses — Gonet, Reyl (now part of Intesa Sanpaolo), Banque Cramer, Rahn+Bodmer, Maerki Baumann, Bank J. Safra Sarasin (Brazilian-owned, Basel) and Liechtenstein's LGT with its Swiss operations — round out a segment of roughly forty institutions.

Minimum deposit at Swiss private banks for foreign clients

Swiss private banks do not publish a price list, and the "minimum deposit" is better understood as a minimum relationship size: the amount of investable assets below which a bank will not open an account because the relationship cannot cover the cost of onboarding and ongoing compliance. For non-resident clients, typical thresholds in 2026 are:

Three things move the number in practice. First, nationality and residence: banks maintain lists of accepted countries, and a client from a jurisdiction the bank considers high-risk may face a higher minimum or a refusal irrespective of wealth. Second, the source of wealth: a clearly documented liquidity event (sale of a business, inheritance) is easier to onboard than complex or opaque wealth, and banks price that effort into the minimum. Third, the service wanted: execution-only custody can be accepted at lower levels than discretionary mandates. The account-opening guide covers the documentation every one of these banks will ask for.

Which Swiss private banks accept U.S. clients?

Since FATCA, most Swiss private banks decline U.S. persons altogether, because serving them requires SEC registration and a separate compliance infrastructure. The exceptions are banks that have built a dedicated, SEC-registered U.S. desk — Pictet North America Advisors and Vontobel Swiss Wealth Advisors are the best-known examples — and UBS, which serves U.S. clients through its American entities. Julius Baer does not accept U.S. persons. A U.S. citizen or green-card holder should ask about this before anything else, since it removes most of the ranking above from consideration.

Partnerships, family-owned banks and listed groups: why ownership matters

Swiss private banks come in three ownership models, and the model shapes how the bank behaves.

Partnerships

Pictet, Lombard Odier, Mirabaud and Bordier are run by managing partners who own the firm. Historically they carried unlimited personal liability — Bordier still does — and although Pictet and Lombard Odier converted to corporate partnerships in 2014, the partners remain the owners and the decision-makers. The practical result is a long planning horizon, no quarterly-earnings pressure, and a reluctance to enter businesses (investment banking, proprietary trading) that could put the partners' capital at risk.

Family-owned and family-controlled banks

UBP (de Picciotto), Edmond de Rothschild, Syz, and to a lesser degree EFG (Latsis) and Vontobel (family shareholder pool) are controlled by a founding family. These banks tend to be more entrepreneurial than the partnerships — UBP has grown largely by acquisition — and often have particular strengths in specific client regions or in alternative investments.

Listed groups

Julius Baer and Vontobel are publicly listed. Listing brings transparency (published capital ratios, audited AUM, analyst coverage) and larger balance sheets that can support lending, but also brings shareholder expectations that can encourage growth-driven risk-taking; Julius Baer's 2023 losses on a single property-group exposure were a reminder that a listed private bank is not immune to that dynamic.

Swiss boutique banks

Below the top ten sit a couple of dozen boutiques managing anywhere from CHF 2 billion to CHF 20 billion. Their appeal is direct access to senior people and highly tailored portfolios; the trade-offs are narrower product ranges, less in-house research, and dependence on a few key individuals. A boutique that specialises in your home region or in a particular asset class (Swiss equities, private markets, art-secured lending) can be an excellent choice; one chosen only because it is small rarely is. Deposit protection is identical across all of them: privileged deposits are covered by esisuisse up to CHF 100,000 per depositor, and custody assets are segregated from the bank's balance sheet — see Swiss deposit protection.

What the best Swiss private banks have in common

"Best" depends on the client, but the houses that consistently rank well on international surveys share characteristics worth checking for:

• A strong capital position well above regulatory minimums — partnerships and family banks in particular tend to hold CET1 ratios of 20% or more.
• No investment-banking arm, so client assets are not sitting next to a trading book.
• Open architecture: willingness to use third-party funds rather than only in-house products, with fees disclosed on a single all-in schedule.
• Booking-centre choice: the ability to hold assets in Switzerland while also offering booking in Singapore, Luxembourg or Hong Kong for clients who want jurisdictional diversification.
• Stable relationship managers: low staff turnover matters more than most prospectuses admit, because the relationship manager is the bank from the client's point of view.

Top Swiss banks for international wealth management: a short-list by client profile

• Conservative, multi-generational family wealth: Pictet, Lombard Odier, Bordier — partnerships with a capital-preservation culture.
• Entrepreneurs wanting credit and structured solutions alongside custody: Julius Baer, UBS, EFG.
• Clients from Latin America, the Middle East or Asia looking for regional expertise: UBP, EFG, Edmond de Rothschild, Julius Baer.
• Alternative investments and hedge-fund access: UBP, Syz, Pictet Alternative Advisors.
• U.S. persons: the SEC-registered units of Pictet or Vontobel, or UBS.
• Below CHF 1 million: a cantonal bank or UBS's entry tiers rather than a private bank — see the cantonal banks in the directory.

Common mistakes when choosing a Swiss private bank

• Choosing by AUM ranking alone. Size buys infrastructure, not attention. A CHF 2 million client is a small relationship at a CHF 600 billion bank and a significant one at a CHF 20 billion boutique.
• Not asking about accepted countries first. Nationality and residence can rule a bank out before wealth is even discussed.
• Comparing headline fees. The all-in cost — management fee, custody fee, transaction charges, fund-level fees and FX spreads — is what matters, and it is rarely on the first page of the proposal.
• Assuming Swiss booking means privacy from your home tax authority. Every bank on this page reports under CRS (or FATCA for U.S. persons). The privacy that remains is commercial and civil, not fiscal — the complete guide explains the distinction.
• Overlooking lump-sum-taxation experience. Clients relocating under Switzerland's forfait fiscal should favour banks that already handle the cantonal documentation routinely.
