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.

UBS CEO Ermotti warns against harsh capital rules ahead of vote

UBS CEO Sergio Ermotti warned against excessive capital rules ahead of a Swiss parliamentary vote. The government proposes UBS hold an extra $20B in capital. Ermotti said 100% CET1 backing for foreign units is excessive, preferring a 90% compromise. UBS estimates it would need $13B in AT1 capital for a 50% requirement. The bank's chairman previously hinted at reconsidering its Swiss future if rules are too strict.

UBS banking rules debate heads to Swiss parliament vote

Swiss lawmakers propose revisiting UBS's banking regulations before a parliamentary vote. The compromise reduces capital requirements from the government's initial proposal of $20B to $13B in Additional Tier 1 capital. UBS argues the original plan would disadvantage it against competitors. The vote follows Credit Suisse's 2023 collapse and its subsequent acquisition by UBS.

UBS could make big savings from Swiss AT1 capital proposal, investors say

Investors say UBS could save hundreds of millions annually if a parliamentary proposal allowing the use of Additional Tier 1 (AT1) bonds is approved, instead of the government's plan requiring Common Equity Tier 1 (CET1) capital. The proposal, which adds some new triggers, is seen as a victory for UBS, though it may face challenges in the lower chamber. AT1 bonds would cost UBS around 7%, cheaper than the 9-10% cost of CET1 capital, according to analysts.
