Swiss Rule Could Cut UBS EPS by 9%
Switzerland's upper house approved a rule requiring UBS to hold 90% common equity tier 1 capital for overseas subsidiaries, which RBC analysts estimate could reduce UBS's earnings per share by 9%. UBS opposes the rule, arguing it harms competitiveness, and has explored options to mitigate its impact. The lower house will debate and vote on the proposal in October and November. RBC warns that easier rules are unlikely.
