The Partnership Advantage
Unlimited Personal Liability
Unlike joint-stock companies, managing partners bear unlimited personal liability with their entire private assets. This ensures maximum prudence in risk management and aligns bank interests directly with client safety.
Independence & Objectivity
We operate independently from large financial groups and do not issue our own financial products. This allows for completely objective advice, avoiding conflicts of interest inherent in banks pushing proprietary funds.
"For me, being a partner means taking responsibility – for ensuring that Rahn+Bodmer Co. remains reliable, independent and approachable for its clients."
— Simon Rahn, Managing Partner

Frequently asked questions
Our clients are private investors, families, and entrepreneurs seeking long-term, reliable, and personalized solutions for managing their capital. Private clients including external asset management comprise 88% of managed client assets (CHF 17.1 billion total as of June 2025). We also work with charitable foundations and external asset managers, offering long-term partnerships for established and aspiring professionals.
The main advantage is unlimited personal liability of managing partners. This guarantees maximum prudence in risk management and complete absence of conflicts of interest, as the bank's well-being is directly linked to the personal wealth of its owners. Partners are fully liable for bank stability with their private assets, rooted in familial tradition since 1750.
Asset security is ensured through several levels: strict Swiss banking legislation, conservative investment policy, the personal liability model of partners, and custody of assets in segregated accounts under strict internal regulations. Rahn+Bodmer Co. holds a FINMA banking license and is subject to FinSA and CISA for investor protection. Deposits up to CHF 100,000 per client are covered by the Swiss deposit guarantee scheme (esisuisse).
We provide comprehensive support for external asset managers, including processing and trading of standard transactions (equities, bonds, derivatives, currencies, precious metals), an advanced e-banking platform for quick data access and transaction administration, and dedicated relationship management. We also assist with succession planning for asset management businesses.
Our investment philosophy emphasizes long-term, fundamental analysis focused on high-quality, liquid securities. The OMNIA mandate provides diversified global exposure across asset classes, while THEMA focuses on Swiss equity ex-SMI with dividend strategies. We prioritize understanding over speculation, selecting only investments we can thoroughly analyze and monitor.
Yes, we work with both Swiss and international private clients. During the initial consultation, we assess your profile, residency status, source of funds, and account purpose to ensure compliance with all regulatory requirements. Our personalized approach allows us to serve clients from various jurisdictions while maintaining strict adherence to Swiss banking regulations.
We offer three main mandate types: Asset Management Mandate (discretionary portfolio management where we make investment decisions within agreed parameters), Advisory Mandate (you make final decisions with our recommendations on individual transactions), and Execution Only (order execution and custody services without advisory responsibility). Each mandate can be customized to your specific needs and risk profile.
We operate independently from large financial groups and do not issue our own financial products. This structural independence allows us to provide completely objective advice and select the best investment solutions on the market for our clients, avoiding conflicts of interest inherent in banks that promote proprietary products.
The account opening process typically involves four stages: initial consultation (1-2 weeks), document preparation and submission (1-2 weeks), interview and verification (1-2 weeks), and account activation (1 week). The total timeline usually ranges from 4-8 weeks, depending on the complexity of your situation and completeness of documentation.
Yes, our comprehensive wealth planning services include tax optimization strategies, pension planning (second and third pillar contributions), estate planning and succession consulting, inheritance planning, and guidance on philanthropic structures. We take a holistic approach to your financial well-being, addressing all aspects of wealth preservation and transfer across generations.
