Initial Assurances and Progress Reports

⁢ UBS had previously reported making “excellent ‍progress” in data transfer, stating that more ‍then two-thirds of Swiss-booked client accounts had already ​been migrated as of late October 2025, according to statements released as⁣ part ‌of its third-quarter results. ⁢ The bank ‍also indicated to Reuters ‌ that it had everything under control and that the integration of CS Switzerland customers would proceed as planned.

Recent Disruptions and Concerns

⁣ Though, this week’s ongoing IT problems have undermined those assurances. A ‌long-time UBS banker reportedly stated yesterday that the disruptions represent “the most crucial‍ tool ​in customer service” being unavailable for several days,preventing access to account balances.
