EFG International, a renowned banking institution, has recently announced its acquisition of Quilvest Switzerland, a private bank based in Zurich. The financial details of this transaction have not been disclosed to the public. The deal is expected to be finalized in the third quarter of 2026, pending regulatory approvals.
Quilvest Switzerland, established in 1932 by the Bemberg family from Argentina, is currently owned by Bemberg Capital, a Luxembourg-based entity. Apart from its headquarters in Zurich, the bank also operates in Montevideo, Uruguay. The bank manages client assets totaling approximately SFr 5.3 billion ($6.8 billion), with a significant portion allocated to assets under management and custody.
The majority of Quilvest Switzerland’s clientele comprises ultra-high and high net worth individuals, with over 90% of the bank’s managed assets attributed to them. These clients are primarily located in Latin America, Western Europe (including Switzerland), and the Middle East. EFG International anticipates that following the acquisition, these clients, including members of the Bemberg family, will have access to a broader range of services.
Adrien de Boisanger, a board member of Quilvest Switzerland and executive chairman of Bemberg Capital, expressed optimism about the partnership with EFG. He believes that this collaboration will bring significant value to all stakeholders, particularly clients and employees, by providing access to a global network and enhanced client service capabilities within an organization that shares the Bemberg family’s values and entrepreneurial spirit.
EFG International’s CEO, Giorgio Pradelli, highlighted the strategic significance of this acquisition, aligning with the company’s existing growth strategy in key markets such as Latin America and the Middle East. Once the transaction is completed, Quilvest Switzerland will operate under EFG Bank, with its investment expertise and product suite integrated into EFG’s platform.
The acquisition will be settled entirely in cash, with EFG estimating a decrease in its CET1 capital ratio by up to approximately 70 basis points. Pradelli reiterated EFG’s commitment to long-term value creation and expressed enthusiasm about the future partnership with the Bemberg family and Quilvest Switzerland team.
In conclusion, EFG International’s acquisition of Quilvest Switzerland signifies a significant milestone in the banking sector, reflecting the company’s strategic vision for growth and expansion in key markets. This development underscores EFG’s ability to attract partners who share its core values and dedication to sustainable value creation across generations.
