Swiss lawmakers punt debate on UBS capital rules into August

Swiss Parliament Delays Decision on UBS Capital Requirements

ZURICH, May 4 (Reuters) - Swiss lawmakers on Monday decided to review alternative options for proposed new capital rules for UBS, putting off a swift decision on the matter and extending a phase of regulatory uncertainty for the bank. The Economic Affairs and Taxation Committee of the upper house of parliament said it would continue debating the capital bill in August, likely meaning it will not face a vote by the full upper chamber before September.

Key Proposals Under Debate

Under debate are the government's proposal to make UBS fully back its foreign units with Common Equity Tier 1 capital, and a compromise pitch that could let it partly use less expensive Additional Tier 1 capital instead.

Committee Hearings and Deliberations

Following hearings with UBS bosses and top officials, lawmakers did not reach a conclusion as committee members sought further clarification on the divisive issue.

"Given the significance of the upcoming decision, the committee wants to discuss various versions and alternatives to the Federal Council's proposal in depth and with sufficient time," the committee said, referring to the government's bill.

Timeline for Decision and Parliamentary Process

Parliament still wants to decide quickly on the UBS regulations, lawmakers said.

Background: Regulatory Context and UBS Response

Regulatory Tightening After Credit Suisse Collapse

Led by Finance Minister Karin Keller-Sutter, Switzerland is tightening regulations after the collapse of Credit Suisse in 2023 left UBS as the country's sole global bank.

UBS Reaction to Proposed Rules

UBS - which has criticised the regulatory plans as "extreme" - said last week its share buyback plans for 2026 depend on getting more clarity on the banking rules, which could mean it must find around $20 billion in additional core capital.

Parliamentary Sentiment and Outlook

While the committee that kicked off debate on the banking bill is widely seen as sympathetic to UBS's argument that costly regulation will hurt its business and the economy, it could face a tougher reception on the floor of parliament.

Key Takeaways

  • The government proposes UBS fully fund its foreign subsidiaries with CET1 capital, but lawmakers may allow partial backing with AT1 instruments to reduce costs.
  • UBS argues the tougher CET1-only rules are “extreme” and claim ambiguity on the rules could impede its ~ $20 billion capital shortfall and delay its 2026 share buybacks.
  • The bill will be debated by the upper house’s Economic Affairs and Taxation Committee on May 4, potentially moving to the upper house in June and requiring approval by the lower house before autumn.
  • UBS is Switzerland’s sole global bank post‑Credit Suisse collapse in 2023, a financial shock that has driven these regulatory revisions.
