What Fürstlich Castell´sche Bank does

Fürstlich Castell'sche Bank is a German private bank headquartered in Würzburg, founded in 1774 and continuously owned for 252 years by the noble houses Castell-Castell and Castell-Rüdenhausen. It serves private banking clients with investable assets of €250,000 or more through personalized advisory across 7 physical branches in Würzburg, Frankfurt, Munich, Nuremberg, Bamberg, Ulm, and Heilbronn, and extends to mass-market customers via the NeoPrivatbank digital platform starting at €50/month with no minimum wealth requirement.

The bank's product portfolio centers on Castell Vermögensverwaltung (active wealth management from €250,000, with individualized service from €2.5 million), a suite of six Castell Publikumsfonds mutual funds spanning multi-asset and equity strategies, and a range of savings and deposit products including Castell Festgeld, Castell Parkkonto, and the Castell Fondssparplan. Supporting services include Castell Immobilien (real estate) and Castell-Versicherungs-Dienst (insurance), both wholly-owned subsidiaries. Technology infrastructure is delivered through the TÜV-certified Castell Banking App, SecureGo plus biometric authentication, snapview video consultations, inSign electronic signatures, and the Atruvia AG core banking platform with PSD2-compliant XS2A APIs. The bank is a member of the Bundesverband deutscher Banken deposit guarantee scheme.

Revenue is generated through a mix of asset management fees on managed portfolios, interest income on lending products and deposit spreads, transaction and card fees, and subscription income from NeoPrivatbank. The 2025 annual report shows a balance sheet total of approximately €1 billion. The bank employs approximately 200 staff across more than 30 specialized departments, supported by a 20-person DialogFiliale phone advisory team. Recent strategic priorities have been digital democratization (NeoPrivatbank 2025), geographic expansion into Frankfurt and Munich, leadership refresh, and product diversification, all within a values-based, conservative governance model that explicitly rejects return-on-investment expectations from its owner families.
