ONE swiss bank consolidates its growth

Banque Profil de Gestion becomes ONE swiss bank SA and Board of Directors appoints new executive board

We are delighted to announce that the merger between Banque Profil de Gestion and ONE swiss bank was executed on Tuesday 1 June 2021. The merged entity’s business name will remain ONE swiss bank SA (“ONE”). ONE symbolises the union of distinct entities operating in the investment industry, merging in pursuit of a single goal: offering high-grade financial services and a modern private banking experience underpinned by proven and time-honoured investment expertise.

The Board of Directors has appointed a new executive team that embodies the bank’s own attributes: energetic, young, ambitious and with a strong entrepreneurial spirit. Grégoire Pennone, Chief Executive Officer, is supported by Alexandre Kuhn, Head of Asset Management (Dynagest by ONE); Karel Gaultier, Head of Wealth Management (and shareholder); Xavier Clavel, Head of Asset Services; Jean-Jacques Schraemli, Chief Operating Officer (and shareholder); and Yves Keller, Chief Financial and Risk Officer.

This Executive Board will work in close cooperation with the recently elected Board of Directors. Geneviève Berclaz, a lawyer and former member of the Swiss delegation to the FATF (Financial Action Task Force), will succeed Nicolas Rosenthal as the bank’s chairperson. When appointed in 2016, Nicolas was tasked with consolidating the bank’s governance framework, developing its business model and energising its growth. With these goals now achieved, Nicolas will be pursuing his activities independently, alongside future ONE shareholders. Jacques Schraemli, 71, is also stepping down – two years after the merger between GS Banque and Banca Arner, which led to the formation of ONE swiss bank. He has worked tirelessly to combine these two banks and place ONE on a firm footing, which has included passing on his expertise and equity investment to his son Jean-Jacques. Four other directors will support Geneviève: Alessandro Bizzozero, Roland Müller-Ineichen, Jean-Claude Favre and Frédéric Binder.

This merger strengthens our convictions and ethos for interacting with clients. We will continue striving for a harmonious balance between tradition and innovation as we seek to offer a whole new experience in private banking. As ever, ‘approachability’, ‘integrity’, ‘agility’ and ‘entrepreneurial mindset’ will be the values that we champion. And we’re still small enough to remain ‘people focused’ at all times.

As a first tangible benefit from the merger, we will soon be able to offer the quantitative management and portfolio insurance services provided by our Asset Management business line, operating under the Dynagest by ONE brand. Dynagest has offered these services to top-ranking institutional investors since 1993 and looks forward to sharing its expertise with private clients.

In business development, we will soon be opening an office in Dubai to expand our footprint to the United Arab Emirates, pending approval from competent supervisory authorities. Our other offices are still Geneva, Zurich and Lugano.

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.
