UBS Group AG has confirmed the completion of a major phase in its integration of Credit Suisse, announcing that all former Credit Suisse clients have now been successfully migrated onto UBS’s infrastructure worldwide. The milestone follows the final transition of Swiss-booked clients and marks a key step in one of the most complex banking integrations to date.

Group CEO Sergio P. Ermotti stated that approximately 1.2 million clients have been smoothly transferred across global systems. He described the achievement as a critical point in combining two global systemically important banks, highlighting the scale and operational demands of the process. While acknowledging that further work remains, Ermotti noted that completing the migration strengthens UBS’s overall structure and prepares the bank to expand its service offering.

UBS Completes Critical Integration Step in Credit Suisse Deal

The integration process began after UBS acquired Credit Suisse in March 2023. Since then, the bank has followed a structured rollout plan, reaching earlier milestones such as the merger of the parent banks and the consolidation of Swiss entities during mid-2024. The latest development signals continued progress toward full operational unification.

Extensive preparation supported the Swiss migration phase. UBS expanded capacity across branches, contact centers, and support teams while conducting more than 80,000 tests to ensure system readiness. Employees also completed over 132,000 hours of training focused on migration-related processes, reflecting the scale of internal coordination required.

System performance has remained stable despite increased demand. UBS reported a 25% rise in payment volumes on its platform, reaching nearly 3.1 million transactions per day. This increase demonstrates the ability of the integrated systems to handle higher operational loads.

Client experience remained a central focus throughout the transition. UBS maintained consistent communication by sending close to three million personalized letters and launching digital hubs for information and self-service tools. Feedback across client segments has remained positive, with trust levels holding steady during the transition.

With the client migration complete, UBS now moves into the final phase of integration, including the shutdown of legacy IT systems. The bank expects to substantially complete the full integration by the end of 2026.
