Swiss upper house vote deals blow to UBS by backing 90% CET1 capital plan
Switzerland's upper house voted to require UBS to back foreign units with 90% CET1 capital, a compromise between the government's 100% proposal and a 50% AT1 option. UBS shares rose 0.9% after the decision, which CEO Sergio Ermotti said would reduce the bank's additional capital bill by $4 billion, totaling around $18 billion. The bill will now move to the lower house, with a final decision expected by 2027.
