The Swiss Parliament's handling of post-Credit Suisse banking reforms has created a closely balanced outlook for passage of the UBS capital rules bill by June 30, 2027. The upper house approved a 90% CET1 requirement for foreign subsidiaries in September 2026, advancing a version stricter than industry preferences but short of the Federal Council's original 100% proposal. The measure now faces the lower house, where debates over competitiveness impacts, additional capital costs estimated at $16-18 billion, and broader financial stability priorities could produce amendments or delays. Cross-party support for tighter rules exists alongside opposition from business groups and UBS, while a potential referendum adds further procedural uncertainty within the resolution window.
