UBS Warns 'Significant' Cost Increases in Swiss Upper Chamber's Recommended Banking Rule Proposals

08:47 AM EDT, 09/01/2026 (MT Newswires) -- UBS Group (UBSG.SW) acknowledged recommendations from the Swiss parliament's upper chamber offering alternatives to the Federal Council's "extreme" banking regulation proposals, but warned that they would still lead to "a significant increase in costs." Under the recommendations from the Economic Affairs and Taxation Committee of the Council of States, or WAK-S, UBS parent bank UBS AG would be required to hold 50% CET1 capital and up to 50% AT1 capital, up from the current 45% and 15%, respectively, the bank said Tuesday. In total, UBS AG would need to keep $30 billion of incremental tier 1 capital since its Credit Suisse acquisition.
