A difficult legacy.

If you start pulling on a thread, sometimes your whole jersey comes apart. UBS Group AG seems to be hoping that a fear of unraveling more aspects of its 2023 Credit Suisse rescue will stop Swiss courts from fully overturning the writedown of the failed bank’s junior debt.

UBS said Wednesday it was joining its regulator, Finma, in appealing an initial court ruling this month that found its wiping out of nearly $17 billion in so-called Additional Tier One bonds from Credit Suisse was unlawful. The Swiss bank even published a handy FAQ on the case, prompting analysts to quiz its executives on whether those bond losses were part of a single transaction with UBS’s takeover of Credit Suisse, or if they were separate, sequential events.
