The story

One Swiss Bank was born from the merger between GS Banque (Geneva Swiss Bank), founded in 2004 by Robert Pennone and Bénédict Hentsch, (then under the name Banque Bénédict Hentsch & Cie) and Banca Arner, founded in 1984 by Giovanni Giacomo Schräemli and Paolo del Bue. The Hentsch family are some of oldest and most renowned bankers in Switzerland and Europe, having founded Lombard Odier Darier Hentsch & Cie in 1798.

In June 2021, Banque Profil de Gestion, founded in 1964 in Geneva under the name Société Financière Privée and One Swiss Bank merged. They decided to continue operating under the name One Swiss Bank and renamed the resultant sub branch Dynagest.

One Swiss Bank opened its Dubai wealth management offices in the Fall of 2021, known as One Swiss Private Wealth. The board appointed Zafar Khan as the head of One Swiss Bank's Emirates division.
