A history with strong convictions

1984 TO 2019

ONE Swiss Bank was born from the merger between the family-owned private banks GS Banque, founded in 2004 under the name Banque Bénédict Hentsch & Cie, then renamed Geneva Swiss Bank in 2014, and Banca Arner, founded in 1984.

ONE swiss bank is the result of a successful merger between two banks driven by a strong desire to bring added value to the wealth management industry and sharing a common vision to develop an authentic and truly modern private banking model.

A brand is born

APRIL 2019

Being true to our core belief, that each client has individual needs and deserves tailored solutions, it is natural for us to present our services under the name of ONE swiss bank.

To act in a symbiose with our client – and with « One for you. One with you. » as guideline – is the promise, that keeps our innovative and entrepreneurial mindset occupied.

Strong commitment


As modern private bankers, we commit to partner with our clients and serve their best interests.

The client charter determines what ONE swiss bank will always strive to deliver and what our clients can expect from ONE swiss bank. This is the meaning of our promise ONE for you. ONE with you.

Our aim is, by respecting this charter, to provide our client with a fruitful and different experience of private banking.

A continuous and accelerating growth


ONE Swiss bank prepares a merger with Banque Profil de Gestion and acquires the entire client portfolio of a private bank in Zurich.

These two transactions are in line with the actions taken in recent years and offer promising perspectives for ONE swiss bank.
