René Sieber

René Sieber devotes his expertise, knowledge and the experience, gained throughout professional and academic careers, to consulting services. He is an Adjunct Professor of finance at the University of Geneva and worked for more than thirty-five years at the heart of financial markets, including more than twenty-five years in executive roles.

Areas of expertise include asset management, especially managing core market risks. René is a recognised pioneer in portfolio insurance, a risk-management technique that he has applied since the nineties, and to the development of which he still actively contributes. He has also been consistently engaged in the field of socially responsible investing (SRI), in which he has gained in-depth knowledge of the realities and challenges over the past twenty years. November 2019, he was appointed Chairman of the Swiss Sustainable Funds Awards Jury. These prizes are awarded by the Geneva Forum for Sustainable Investment (GFSI). June 2021, he joined the Center of Competence for Sustainable Finance (CCSF) of the University of Zurich, as a member of its Scientific Advisory Board.

His services are aimed at boards of directors, foundation boards and investment committees, all of whom can benefit from his expertise – acquired by managing assets for institutions and jointly heading a specialist investment-services firm – as well as from his professional network.


After earning a Ph.D. in Economics from the University of Geneva (UNIGE) in the field of international investment and conducting research at the Massachusetts Institute of Technology (MIT) for a year as a Visiting Scholar, René Sieber began his asset management career in 1985 as an economist at the Geneva-based Banque de Dépôts (a constituent part of the future EFG Group), where he was also responsible for setting investment policy.

In 1987, he joined Unigestion S.A., an asset management company in Geneva, where he was in charge of fixed-income investment strategy. In 1990, he was appointed head of institutional account management.

From 1993 to 2018, René took the route of entrepreneurship, co-founding Dynagest S.A. – an independent asset manager specialising in interest-rate and quantitative management for an institutional client base. In 2006, Dynagest S.A. was granted a securities dealers’ licence by the Swiss Federal Banking Commission (today FINMA). In addition to shared responsibility for defining corporate strategy and developing business, René led and developed quantitative portfolio insurance management as well as supervising research and fixed-income management.

The success of portfolio insurance risk-management products, particularly currency and equity overlays, hoisted Dynagest S.A. (with AUMs that have exceeded CHF five billion) into Investment and Pensions Europe’s Top 400 Asset Managers rankings for several years running. René played a major role in achieving a strong market position for Dynagest S.A., which in the late 1990s became known in Switzerland as a pioneer in asymmetric market-risk management. He also contributed to the company's development in fixed income.

Capitalising on his extensive understanding of institutional investment, René has also worked actively to promote and develop socially responsible investing (SRI) in Switzerland. As a director of Ethos Services SA - the operating company of Ethos, Swiss Foundation for Sustainable Development - he acquired, from 2002 to 2022 (in accordance with the maximum term of office provided for by Ethos),  in-depth knowledge of the realities and challenges facing those investing in this field. As Chairman of the asset management committee, he notably contributed to the development of the range of Ethos funds dedicated to responsible investment.

Underlying his commitment to the banking and financial services sector, René has since 1988 lectured in finance at the University of Geneva where he was was appointed Adjunct Professor in 2019 and Visiting Professor in 2021. He currently teaches the Fixed Income & Credit Risk course on the M.Sc. in Wealth Management. He is also co-heading the new DAS (Diploma of Advanced Studies) in Asset Management.

As a director of Ethos Services SA from 2002 to 2022 (in accordance with the maximum term of office provided for by Ethos), René is fully aware of the realities and challenges inherent to SRI and puts this knowledge to use for both service providers and investors.
