Expect downward pressure on UBS stock due to materially higher capital requirements reducing capital flexibility and return metrics. Monitor parliamentary deliberations on foreign participation rules through 2027 for potential modifications. The 17.6% projected CET1 ratio is well above peer averages, suggesting potential for future capital returns if regulations are softened, but near-term headwinds remain.

Executive Summary
UBS has responded to new Swiss regulatory proposals that would significantly increase its capital requirements, estimating a $4 billion reduction in CET1 capital from changes to software amortization and valuation adjustments, and an additional $20 billion required from full deductions of foreign participations. These changes, if adopted, would impose substantial capital costs and negatively impact UBS's capital ratios.
Key Facts
- Swiss government published final Capital Adequacy Ordinance (CAO) requiring UBS capitalized software to be amortized over no more than 3 years for capital purposes, regardless of useful life.
- Prudential valuation adjustments will be revised, leading to higher capital deductions; effective January 1, 2027.
- Proposed changes to treatment of foreign participations would fully deduct investments in foreign subsidiaries from UBS AG's CET1 capital, phased in over 7 years starting in 2027.
- Total incremental CET1 capital required at UBS AG: ~$22 billion, contributing to a de facto minimum CET1 ratio of ~18.4% at group level.
- Including $4 billion CET1 impact from CAO changes, group CET1 ratio would fall to ~17.6%, down from prior levels.
- Total additional CET1 capital required due to all post-Credit Suisse acquisition regulations: ~$37 billion, with annual capital cost of ~$3 billion.
- UBS disagrees strongly with the proposals, calling them extreme and misaligned internationally, and warns of far-reaching consequences for the Swiss economy.
Financial Impact
Approximately $4 billion reduction in consolidated CET1 capital from CAO changes, and an additional $20 billion in required capital from proposed foreign participation rules, totaling $22 billion incremental CET1 requirement at UBS AG. Total additional CET1 capital needed post-acquisition: $37 billion, with $3 billion annual cost.
Risk Factors
- Regulatory risk: Final adoption of foreign participation rules could force $20 billion in additional capital retention.
- Economic risk: BAK Economics study estimates up to CHF 34 billion in cumulative GDP losses for Switzerland over 10 years due to reduced credit supply.
- Capital cost risk: $3 billion annual cost from $37 billion incremental capital reduces earnings power and return on equity.
