UBS Regulation: Capital Requirements Between Stability and Competitiveness

Executive Summary

The Federal Council is planning stricter capital requirements for UBS to minimize systemic risks following the Credit Suisse crisis. The bank and business associations criticize the macroeconomic consequences, while experts from ETH Zurich propose a phased implementation with an interim evaluation (Mid-Term Review). This would ensure both stability and seriously address justified concerns.

Detailed Summary

Background: UBS as a Systemic Risk

Following the acquisition of Credit Suisse by UBS in January 2023, Switzerland has only one globally systemically important large bank. With a balance sheet total more than double Switzerland's GDP, UBS is central to the financial market and overall economy. It operates internationally in lending, retail banking, asset management, and investment banking.

Federal Council Regulatory Proposal

The Federal Council has initiated a consultation on new capital requirements, whose core is 100% capital backing of foreign subsidiaries. This measure is based on two central findings:

1. Availability Problem: Capital in foreign subsidiaries (e.g., USA) may not be available to support the parent company in a crisis.
2. Preventing Double Burden: Without 100% backing, parent company capital must serve two purposes – for both its own and subsidiary losses.

The Credit Suisse experience confirms this risk: the parent company rapidly deteriorated because subsidiary losses were not adequately backed.

Importance of Capital

Capital is a bank's loss buffer – it directly reduces default probability and builds confidence among customers and in the system. Unlike debt capital, losses do not need to be repaid; capital simply shrinks. This makes it the most reliable loss absorption mechanism.

Criticism from UBS and Business Associations

UBS opposes the requirements – supported by Economie Suisse and conservative parties. Main arguments:

• Capital costs increase and slow growth in capital-intensive areas
• Return on Equity measurably declines
• International competitiveness threatened compared to European and US large banks
• Credit provision could become more expensive, Swiss companies migrate to competitors

Alternative: AT1 Bonds

UBS and associations propose allowing AT1 bonds (contingent convertible bonds). These automatically write down and convert to capital when a bank faces difficulties. Theoretically elegant – practically problematic:

Implementation Problems:

• Trigger Timing: When exactly to trigger? At Credit Suisse, the trigger could not be activated in time
• Panic Reactions: Write-down signals distress and reinforces flight reactions
• Legal Uncertainty: Complex prospectuses led to lawsuits at CS; first instance ruled in favor of AT1 holders
• No Optimal Design: Science debates ideal trigger mechanisms, but no consensus exists

Conclusion: AT1 bonds are not a complete substitute for hard capital (equity issuance, retained earnings).

Macroeconomic Costs: Differentiated Analysis

Costs for UBS itself:

• Manageable through profit retention and organizational optimization
• However: Measurable negative effects on growth and profitability

Macroeconomic costs (three dimensions):

1. Credit Provision: Higher credit interest rates, fewer investments – but companies can switch to other banks
2. Financial Sector Value Added: Reduction possible through capital tightening
3. International Financial Services: Costs for Swiss multinationals could increase

Expert Evaluation: Expected macroeconomic costs are rather modest, as adaptation occurs gradually over years and markets have time to adjust.

Core Statements

• Capital requirements are scientifically justified: They demonstrably reduce the probability of another banking crisis.
• UBS must hold more capital than international competitors – the delta is not extreme, only moderately higher.
• AT1 bonds are not a valid alternative: Trigger mechanisms, legal uncertainty, and panic reactions make them impractical.
• Macroeconomic damage likely limited: Gradual adjustment over 7+ years substantially reduces shocks.
• Mid-Term Review creates transparency: Independent evaluation in 2031 could seriously address concerns and adjust if necessary.

Stakeholders & Affected Parties

Opportunities & Risks

Action Relevance

For the Federal Council/Finance Department:

• Pass regulatory proposal with built-in Mid-Term Review – this reduces political resistance through documented interim evaluation
• Establish independent evaluation body by December 31, 2031 at latest with clear criteria (credit provision, competitiveness, stability)
• Publish transparency report – clarity for market participants reduces uncertainty

For UBS:

• Begin gradual adaptation of business models (not ad hoc, but strategically over 7+ years)
• Prioritize cost optimization and organizational restructuring
• Prepare dialogue with authorities for evaluation

For Business Associations:

• Model realistic scenarios instead of blanket warnings – conduct fact-based discussion
• Do not position AT1 bond designs as main solution (lacking practical feasibility)

For Market Participants:

• Regularly monitor evaluation results from 2031 onward for risk assessment
