Switzerland's parliament is currently deliberating a significant banking regulation that arises in the wake of the Credit Suisse collapse. A proposed compromise would allow UBS to support its foreign subsidiaries with 70% to 80% Common Equity Tier 1 capital rather than the initially suggested 100%.
This change could prevent UBS from needing to raise as much as $22 billion in extra capital. Such a large sum could shift the bank's strategic planning dramatically. Common Equity Tier 1 capital serves as the highest quality regulatory buffer, consisting of common shares and retained earnings.
When UBS took over Credit Suisse in 2023, it acquired not just an expansive global operation, but also a range of associated risks. Swiss regulators initially reacted by recommending that UBS fully cover its international branches with CET1 capital. The refined proposal seeks to ease this requirement to a range between 70% and 80%. While this still places a considerable capital burden on UBS, it is far less daunting than the prospect of a $22 billion capital raising initiative.
Discussions are set to continue in August 2026 within the Economic Affairs and Taxation Committee of the Swiss upper house.
What was the backstory for these regulatory changes? In late 2025, center-right lawmakers initially introduced a compromise involving AT1 capital, which is a type of debt that converts to equity in crises. This acted as a catalyst, pushing UBS shares to a market high above SFr35. The latest modifications concerning CET1 requirements exhibit a similar trend, as lawmakers gradually move away from the most intense regulatory stance while upholding credibility surrounding financial stability.
What are the implications for investors? The prior compromise regarding AT1 capital showcased the sensitivity of UBS's stock to regulatory developments. Should the CET1 capital requirement settle at 70% to 80%, UBS can avoid the need for a multibillion-dollar capital influx. This capital won't need to be raised through share sales or retained earnings, which would otherwise potentially be redirected from dividends and stock buybacks.
It's important to note that the discussions taking place are strictly related to conventional banking regulation and are separate from any concerning digital assets, cryptocurrencies, or blockchain governance. Ultimately, parliamentary voting will finalize the new framework, and there remains no guarantee that the proposed compromise will remain at the 70% to 80% mark.
