UBS’s Swiss wealth-management operation is facing a growing exodus of senior private bankers, adding to concerns about staff turnover in the bank’s compliance function.
This has also raised questions about how the group is balancing global expansion against its home market.
A local financial blog says Franco Frattura, who leads UBS’s Entrepreneurs and Executives team serving wealthy clients in Zurich, resigned last Friday. It also reports that Christina Stäger, a managing director with long experience at UBS, is moving to Lombard Odier, where she will lead ultra-high-net-worth coverage for German-speaking Switzerland.
Are further departures expected, potentially including entire teams?
UBS has not confirmed the reported exits or commented on the allegations about its treatment of Swiss wealth management.
Senior Talent Moving To Rivals
Frattura is described as part of UBS’s institutional fabric in Zurich, leading a team that advises some of the city’s wealthiest entrepreneurs and executives. His destination is not yet known.
Stäger’s move to Lombard Odier is especially notable because she is taking responsibility for ultra-high-net-worth clients across German-speaking Switzerland, a core segment for Swiss private banks.
Surces claim the departures reflect a broader loss of confidence among experienced Swiss private bankers, who feel they have limited prospects at UBS. This echoes a wider narrative of senior-staff turnover at the bank.
UBS Repeatedly Emphasises Global Growth While Swiss Workforce Continues To Shrink
The wealth-management concerns come shortly after Inside Paradeplatz reported turmoil in UBS’s compliance function following Michelle Bereaux’s appointment as Group Head of Compliance and Operational Risk Control .
That report said two key compliance figures had left and alleged that more than 100 compliance specialists in Switzerland had departed in recent months, including anti-money-laundering and risk-monitoring staff . UBS did not respond to those allegations .
Notably, compliance and client-facing advisory are both central to UBS’s reputation.
Does UBS see Swiss wealth management as less strategically important than the United States, Asia and the Middle East, where it wants to grow? An unnamed source described Switzerland as “peanuts” from the group’s perspective, while another said departing senior bankers are being replaced with cheaper junior staff.
UBS has repeatedly emphasised global growth and integration since acquiring Credit Suisse, while its Swiss workforce has continued to shrink. The bank reported 61,899 full-time-equivalent employees at the end of 2025, down by 7,083 from the previous year.

Client Retention Becomes The Test
The report alleges that UBS is relying heavily on client-retention measures to limit the damage from departing bankers, including making account closures slow and costly. That allegation points to the central commercial risk: wealthy clients often follow trusted advisers.
UBS’s official leadership changes show why the stakes are high. Michelle Bereaux became Group Head of Compliance and Operational Risk Control on 1 January 2026, while former compliance chief Markus Ronner moved to the board as vice-chairman . UBS described Ronner’s tenure as having built industry-leading compliance and risk-control frameworks .
The immediate question is whether the reported departures are isolated senior moves or the start of a wider loss of experienced Swiss private bankers. The longer-term question is whether UBS can retain both its wealthiest Swiss clients and the compliance expertise needed to manage an increasingly complex post-Credit Suisse group.
