Switzerland's parliament is negotiating a compromise that could cut UBS's new capital requirement from $20 billion to roughly $15 billion. A key vote is set for August 31, 2026, while the Swiss National Bank continues to back the tougher original demand.
Swiss lawmakers are working on a deal that would trim the extra capital UBS must hold, potentially saving the bank billions of dollars ahead of a parliamentary vote. The original requirement, estimated at $20 billion in additional Common Equity Tier 1 capital, followed regulatory reforms triggered by the collapse of Credit Suisse in March 2023, an event that turned UBS into a larger systemically important institution. Lawmakers are now weighing alternatives that could trim the additional capital needed to roughly $15 billion.
What's on the table
The Swiss Federal Council proposed in April 2026 that UBS fully back its foreign subsidiaries with CET1 capital, the highest-quality form of bank capital. UBS has argued that full CET1 backing for foreign units imposes costs far exceeding what its global competitors face.
The compromise involves two adjustments. First, lawmakers are considering letting AT1 convertible bonds, a cheaper form of capital, cover up to 50% of the foreign subsidiary requirement — a change that could reduce the CET1 impact to as little as $400 million. Second, rather than demanding 100% CET1 backing, parliament is exploring a range of 70% to 80%, which would still raise UBS's capital buffers but bring the total additional requirement down to approximately $15 billion.
The politics behind the numbers
A key parliamentary vote is scheduled for August 31, 2026. The Swiss National Bank has backed the government's original position, with the SNB's vice chairman stating on August 26, 2026, that full CET1 backing is proportional given UBS's size and systemic importance.
Market reaction and investor implications
UBS shares climbed to 17-year highs in December 2025 when initial signals of a compromise first emerged, then stabilized as the outcome remained uncertain. The distinction between CET1 and AT1 capital matters for shareholders: CET1 is essentially equity, so UBS would need to retain more earnings or issue new shares, diluting existing holders. AT1 bonds, by contrast, are debt that converts to equity only under extreme stress, making them cheaper for the bank to maintain and non-dilutive under normal conditions.
If the compromise holds and AT1 bonds cover a substantial portion of the foreign subsidiary requirement, UBS would retain more flexibility in deploying capital, which is directly relevant to the bank's ability to return cash to shareholders.
