UBS is facing uncertainty due to a likely delay in implementing stricter capital rules, potentially extending the timeline to at least 2028. This comes in the wake of the Credit Suisse collapse and subsequent acquisition by UBS, which has seen its shares rise 80% since then, despite recent dips. The debate now centers on the capital requirements for UBS's foreign subsidiaries, with discussions shifting to parliamentary consideration. While UBS lobbies against excessive requirements, it acknowledges the need for balanced regulations that align with international standards.
