UBS Stung with $17B Capital Call After Swiss Parliament Vote

UBS faces significant financial challenges after Switzerland's upper house voted to require the bank to hold 90% Common Equity Tier 1 capital backing for its foreign subsidiaries at the parent level. This move is estimated by Goldman Sachs and Citigroup to force UBS to raise around $17 billion in additional capital.

The Swiss Council of States made this decision on September 23, effectively giving UBS an expensive homework assignment. The bank has labeled the decision excessive and warned it could damage its competitive position against global peers operating under more lenient capital regimes.

According to Goldman Sachs and Citigroup's estimates, the parliamentary measure would impact UBS with around $17 billion in fresh capital demands, while the bank's own internal estimate puts this figure at approximately $16 billion. This adds a separate burden of $2 billion from upcoming ordinance changes, totaling roughly $18 billion.

The regulatory overhaul is linked to the 2023 collapse of Credit Suisse, which UBS absorbed through a government-brokered emergency rescue. Swiss lawmakers responded with reforms aimed at ensuring that UBS's foreign units could be wound down in a crisis without dragging the parent company into the wreckage.
