Among the changes, the banking group said it has nominated a new chair for its Luxembourg business and announced other shifts among its C-suite and board leadership.

Switzerland-listed EFG International said yesterday that it has put forward André Prüm as the new chair of the board of directors of its subsidiary EFG Bank (Luxembourg), with effect from 1 January 2026. 

Prüm will succeed Yves Maas, who is stepping down as chair to take on the role of CEO of EFG Bank (Luxembourg), also on 1 January, the group said in a statement. Prüm is professor of law at the University of Luxembourg, where he holds the chair in financial and business law and was the founding dean of the Faculty of Law, Economics and Finance. He is qualified as a French law professor (Professeur agrégé des Facultés de droit de France).

Lena Lascari will retire from her operational role as CEO of EFG’s Luxembourg subsidiary, which she has held since 2019, and will remain a board member.

Pascal Julliard has been appointed as deputy CEO and head of Private Banking Luxembourg, effective 1 October 2025, reporting to the CEO of EFG Bank (Luxembourg).

Yves Maas has been board chair of EFG Bank (Luxembourg) since 25 April 2024. In his new role as CEO, he will be responsible for leading the overall growth strategy of EFG’s strategic hub in Luxembourg and in continental Europe through its branches in Portugal and Greece. Maas spent a large part of his career at Credit Suisse, where he held senior positions, including serving as MD of international private banking operations and as CEO and country head of Credit Suisse Luxembourg. In 2017, he was appointed chairman of the board of Credit Suisse Luxembourg, a post he held until February 2024. 

Lascari, who joined EFG in 2014, has been the CEO of EFG Bank (Luxembourg) SA since 2019.

Julliard brings 25 years of industry experience. Before joining EFG Julliard served as CEO and executive director of HSBC Global Private Bank (Luxembourg) from 2022 and as head of private banking Luxembourg from 2020 to 2022. Prior to that, he spent seven years at HSBC Private Bank in France, as head of credit advisory.
