UBS Gains 2% as Swiss Lawmakers Consider Cutting Capital Requirement

UBS shares rose nearly 2% Tuesday after Reuters reported that Swiss lawmakers are actively considering reducing the bank's proposed capital requirements — a development that could cut billions of dollars from what had been an increasingly contentious regulatory burden hanging over Switzerland's only remaining global lender.

The move comes as parliamentarians weigh a compromise between the government's proposed 100% Common Equity Tier 1 (CET1) backing requirement for foreign subsidiaries and the bank's own position that such requirements are excessive and competitively damaging.

What's Actually Being Proposed — and What It Would Cost

The scale of the capital question is significant. Under the government's draft legislation submitted to parliament in April, UBS would need to raise approximately $20 billion in additional CET1 capital if the full 100% backing requirement were adopted for its foreign subsidiaries.

The emerging parliamentary compromise is meaningfully different. Four sources familiar with the deliberations told Reuters that lawmakers are considering requiring UBS to back foreign units with approximately 70% to 80% CET1 capital.

Analysts estimate that an 80% threshold would reduce the additional capital requirement to roughly $15 billion — saving UBS approximately $5 billion versus the government's original proposal. A 50% requirement — which was also discussed at a parliamentary hearing last month — could allow UBS to maintain its current core capital levels without raising additional funds at all.

The upper-house committee currently reviewing the legislation is described as "widely viewed as sympathetic to UBS's argument that overly burdensome regulation could undermine the bank and the wider economy." 

However, tougher requirements are expected to be advocated when the bill reaches a full parliamentary vote later this year, with centrist and moderate lawmakers likely to hold the balance of power. Two sources indicated a compromise requiring CET1 backing somewhere between 50% and 100% could emerge from the committee as a negotiating position capable of securing broader support.

The Credit Suisse Shadow and Why Switzerland Is Legislating

The regulatory overhaul is a direct response to Credit Suisse's 2023 collapse — a crisis that forced Switzerland into an emergency rescue and resulted in UBS absorbing its former rival. The event exposed how thin the regulatory buffers were for foreign subsidiary funding and how quickly confidence in a systemically important bank can evaporate.

The draft legislation's core objective is preventing a repetition: by requiring UBS to maintain substantial CET1 backing for its foreign subsidiaries, regulators want to ensure that a crisis at a foreign unit cannot destabilise the parent bank or require another taxpayer-funded rescue. The public liquidity backstop — an emergency funding facility planned for large banks — is also under discussion, with some sources indicating that the fee UBS would pay for access to that facility could be linked to its overall capital requirements.

The tension between financial stability objectives and banking sector competitiveness is the political fulcrum of the entire debate. Finance Minister Karin Keller-Sutter has advocated for the tougher framework; UBS CEO Sergio Ermotti acknowledged last week that the bank was likely to emerge from the regulatory overhaul with at least a "black eye," suggesting UBS expects some regulatory tightening even if the final outcome is more lenient than the 100% proposal.

The AT1 Capital Angle

Some lawmakers are also exploring whether Additional Tier 1 (AT1) capital could be used alongside CET1 to preserve UBS's competitiveness without sacrificing the overall capital framework's resilience. AT1 instruments — contingent convertible bonds that absorb losses before equity in a crisis — were the subject of significant controversy during the Credit Suisse rescue, when CHF 16 billion in AT1 bonds were written to zero even as equity holders received some recovery value, a sequencing that shocked bond investors globally.

The Swiss government regards AT1 instruments as carrying greater risk than CET1, making regulators reluctant to allow substantial AT1 substitution. But the inclusion of some AT1 capacity within the framework would reduce the raw equity capital UBS needs to raise, improving its returns on equity and competitive positioning against European and American banking peers that operate under less stringent domestic requirements.

The 2% Tuesday gain reflects the market's reassessment of the regulatory tail risk that had been weighing on UBS shares. A requirement at 80% rather than 100% saves approximately $5 billion in capital raising — capital that would otherwise dilute shareholders, constrain returns, and pressure the dividend. The outcome is not yet determined: the committee's sympathetic stance may be moderated when the bill reaches a full parliamentary vote, and tougher advocacy from centrist lawmakers could push the final number closer to 100% than the current compromise discussions suggest.

The legislative timeline remains the key uncertainty. UBS investors should monitor the committee's draft proposal — expected before the parliamentary vote later in 2026 — as the first concrete indication of where the 50%–100% range will ultimately land.
