Swiss Private Banks: Minimum Requirements, Services, and How to Apply

Swiss private banking is among the most developed wealth management industries in the world, managing approximately one-quarter of all globally cross-border managed assets [VERIFY — SBA annual report figure]. Private banks differ fundamentally from retail or cantonal banks: they serve high-net-worth (HNW) and ultra-high-net-worth (UHNW) clients, they focus on investment management rather than transactional banking, and their fee model is typically based on assets under management (AuM) rather than per-transaction charges. Switzerland's combination of political neutrality, currency stability, FINMA regulation, and an extensive double-taxation treaty network makes it the pre-eminent jurisdiction for private banking clients seeking long-term capital preservation and growth.

Definition: what makes a bank a "private bank"

In Switzerland, the term "private bank" (Privatbank) historically referred to banking partnerships where the partners bore unlimited personal liability for the bank's obligations — structurally analogous to a law firm partnership. This model ensured the partners had strong skin-in-the-game incentives to manage client assets conservatively. The most enduring examples of this model — Pictet, Lombard Odier — converted to limited partnership structures (Kommanditgesellschaft) in the 2010s, preserving the partnership ethos while complying with modern regulatory capital requirements.

Today, the term "private bank" in Switzerland most commonly refers to any FINMA-licensed bank (Banklizenz under BankG) that focuses primarily or exclusively on wealth management services for HNW and UHNW clients — regardless of its legal form. All are subject to full BankG supervision, FINMA capital and liquidity requirements, and GwG anti-money-laundering obligations.

Minimum AuM requirements by institution

Private banks set minimum investment thresholds to ensure the account is economically viable given the service cost. These thresholds are indicative — banks routinely make exceptions for clients with high growth potential, referrals from existing clients, or complex mandates that generate additional advisory revenues.

Services offered by Swiss private banks

Discretionary portfolio management

Under a discretionary mandate (Vermogensverwaltungsmandat), the client delegates investment decisions to the bank within an agreed investment policy statement (IPS). The IPS defines risk tolerance, currency preferences, geographic allocation, asset class limits, and excluded sectors. The bank's investment team manages the portfolio and reports quarterly. The client receives a performance report but does not approve individual transactions. This is the most common mandate type for UHNW clients who prefer to delegate day-to-day management.

Advisory mandate

Under an advisory mandate (Beratungsmandat), the bank recommends investments but the client makes the final decision on each transaction. The relationship manager presents investment opportunities, analyses, and structured product ideas; the client instructs execution. This suits clients who want to remain engaged with investment decisions or have specific views on particular assets, sectors, or geographies. It is typically more time-intensive for the client and the relationship manager.

Execution-only

Some private banks offer execution-only services for sophisticated clients who manage their own investment strategy and require only trade execution and custody. Suitability checks are reduced under execution-only mandates (MiFID II / FinSA equivalent in Switzerland). Fees are typically lower — pure transaction and custody costs without an advisory layer.

Ancillary services

• �Estate and succession planning: Cross-border estate analysis, trust structuring, philanthropy vehicles (Swiss foundations, charitable trusts).
• �Family office services: For clients with CHF 50M+ AuM — consolidated reporting across all assets, family governance, next-generation wealth education.
• �Fiduciary and structured products: Structured notes, capital-protected products, barrier reverse convertibles, and other derivative-based solutions.
• �Art banking and collectibles: Art finance (loans secured on art), art custody and logistics, collectibles valuation.
• �Philanthropy advisory: Setting up Swiss foundations (Stiftungen), donor-advised funds, and impact investing mandates.

Fee structure

Swiss private banking fees are not publicly disclosed in tariff schedules — they are negotiated individually based on AuM, mandate type, and client relationship. General market benchmarks [VERIFY — fee levels subject to change]:

• �All-in management fee (discretionary): Typically 0.5%–1.5% of AuM per year, depending on portfolio size and complexity. Larger portfolios attract lower percentage fees.
• �Performance fee: Some banks charge 0%–10% of outperformance above an agreed benchmark; others apply a flat fee only [VERIFY].
• �Custody fees: Often included in the all-in fee for discretionary mandates; charged separately for advisory or execution-only clients.
• �Transaction costs: For advisory and execution-only mandates, per-trade commissions apply (typically basis-point-based on trade value) [VERIFY].

Swiss private banks are required under the Swiss Financial Services Act (FinSA — Finanzdienstleistungsgesetz, effective 2020) to disclose all costs and charges to clients before mandate commencement, including third-party retrocessions received by the bank. Retrocession transparency was a significant regulatory development: clients can now waive or claim retrocessions that the bank receives from fund managers and structured product issuers.

Account opening process for non-residents

Non-resident individuals can open Swiss private bank accounts. The process is more document-intensive than for Swiss residents due to cross-border compliance requirements and AEOI reporting obligations. The typical sequence:

• �Initial contact and relationship manager assignment: Introduction through a referral, law firm, or direct approach. A relationship manager (RM) is assigned and conducts an initial call or meeting to assess fit.
• �KYC document submission: Certified passport copy, proof of residential address (utility bill or official document, dated within 3 months), tax identification number (TIN) for each jurisdiction of tax residence.
• �Source of wealth documentation: Written declaration of origin of wealth (inheritance, business sale, accumulated savings, investment returns) supported by corroborating documents — e.g., sale and purchase agreement for a business sale, estate distribution documents for inheritance.
• �Source of funds for initial deposit: Bank statements or wire transfer documentation showing the funds moving from the client's existing account to the Swiss bank.
• �Bank reference letter: A letter from the client's existing primary bank confirming the relationship and account standing. Not always required but common for new international clients.
• �Investment questionnaire (suitability assessment): Required under FinSA for discretionary and advisory mandates. Assesses risk tolerance, investment horizon, financial literacy, liquidity needs.
• �Compliance review: The bank's compliance team reviews the file; the process typically takes 2–8 weeks depending on the client's jurisdiction of residence and source of wealth complexity.

AEOI and transparency for non-residents

All Swiss private banks participate in the CRS (Common Reporting Standard) automatic exchange of information framework. Non-residents' account balances and income are reported annually to their home tax authority. A client resident in the EU, the United Kingdom, the Gulf states (which have signed CRS [VERIFY by country]), or other partner jurisdictions will have their Swiss private bank account reported to their home country's tax authority without any need for a specific request.

This is a non-negotiable feature of a Swiss private banking relationship in 2026. Clients should ensure their Swiss private banking assets are properly declared in their home jurisdiction before or at the time of account opening. Goldblum & Partner's tax advisory team can coordinate the disclosure and regularisation process if required.

Why Switzerland for private banking

• �Political and economic stability: Switzerland has not participated in a war since 1815 and maintains a tradition of political neutrality. The CHF is one of the world's most stable currencies, with a long-term appreciation bias against the EUR and USD.
• �FINMA regulation: FINMA is one of the world's most respected financial regulators. Swiss banks are subject to rigorous capital adequacy, liquidity, and conduct requirements — providing clients with confidence in institutional counterparty quality.
• �Wealth management expertise: Switzerland has centuries of experience as a financial centre [VERIFY — claims of "700 years" are disputed; modern private banking begins approximately 18th century]. The depth of investment talent, product structuring capability, and multi-generational relationship management is unmatched by most competing centres.
• �DTT network: Switzerland has one of the world's most extensive double-taxation treaty networks — over 100 DTTs — reducing withholding tax friction on dividends and interest for cross-border portfolios.
• �Residual civil confidentiality: Art. 47 BankG banking secrecy still protects Swiss account information from disclosure in foreign civil proceedings (e.g., divorce litigation, commercial disputes) that do not rise to the level of a criminal mutual legal assistance request. This is a remaining meaningful confidentiality benefit.

Alternatives for lower minimum assets

Not all HNW individuals meet the minimum AuM thresholds of the major private banks immediately. Several alternatives provide a stepping-stone into Swiss private banking services:

• �Cantonal banks (Kantonalbanken): ZKB (Zurcher Kantonalbank), BCV (Banque Cantonale Vaudoise), and BCG (Banque Cantonale de Geneve) offer private banking services with lower minimum thresholds than the major private banks, and carry a cantonal government guarantee on deposits.
• �Raiffeisen: Switzerland's largest cooperative banking network offers private banking and investment advisory services through its member banks, with lower entry thresholds than dedicated private banks.
• �PostFinance: While not a traditional private bank, PostFinance offers investment products and savings management, accessible to clients who are not yet in the HNW segment.
• �Independent asset managers (IAMs): FINMA-regulated external asset managers can manage client portfolios held in custody at a Swiss bank, often with lower minimum thresholds than direct private bank mandates.
