Paul McEwen, UBS’s global head of technology services, is leaving the bank, according to two reports from a local financial blog citing sources. The outlet said staff were informed last week and that McEwen’s final day would be tomorrow, Wednesday, 20 September 2026. UBS did not respond to its questions about the departure or a successor.
The reported exit comes as UBS places greater emphasis on artificial intelligence across its operations. Since January, its Group Technology function has reported to Beatriz Martin Jimenez, the bank’s group chief operating officer. UBS said when it announced the change that the structure would help it prioritise technology and AI initiatives while completing the integration of Credit Suisse.
Could McEwen’s departure be connected to disagreements over the bank’s AI push? Again, UBS has not established why he is leaving.
McEwen had recently written on LinkedIn that organisations should support the shift to “AI-native” working without forgetting “what it means to be human in the process.”
That comment does not, on its own, demonstrate a dispute with Martin or explain his reported exit.

UBS has publicly described AI as part of its technology strategy. The bank says it is using AI tools in areas including research, employee services and software development, while training staff in their use. It has not said that McEwen’s reported departure resulted from its AI strategy.
Martin’s expanded role makes the leadership question significant for UBS: her responsibilities include delivering technology services and coordinating technology-enabled change across the group. But reports of an internal power struggle, or claims that the bank has chosen her to succeed chief executive Sergio Ermotti, remain unconfirmed. UBS has not announced a CEO successor.
