UBS Weighs Leaving Switzerland as Lawmakers Hand It a $33 Billion Capital Bill

Switzerland's Council of States voted 29-16 to require 90% hard core capital at UBS foreign units, adding about USD 33 billion in capital needs.

UBS's home-market advantage is suddenly looking less like an anchor and more like a liability. Switzerland's Council of States voted 29 to 16 on Wednesday to require foreign subsidiaries of the country's last remaining banking heavyweight to hold 90% of their capital in hard core equity (CET1), discarding an earlier compromise that would have split the requirement evenly between CET1 and AT1 bonds. The broader banking law package cleared the smaller chamber 33 to 10.

The decision lands at an awkward moment for a bank that has spent three years digesting Credit Suisse. Finance Minister Karin Keller-Sutter had originally pushed for full 100% coverage, while UBS itself lobbied for the 50/50 mix. Neither side got what it wanted.

What the Rule Would Actually Cost

The arithmetic is what matters for shareholders. By UBS's own calculations, the 90% threshold alone would tie up roughly USD 16 billion in additional hard core capital at UBS AG. Add USD 2 billion from other measures and USD 15 billion in requirements already imposed after the emergency Credit Suisse takeover, and the total additional capital need reaches about USD 33 billion.

Today, foreign units face only a 60% requirement, and it need not be met entirely with CET1. Should the stricter version become law, management puts the recurring annual burden at up to USD 2.5 billion. That figure is the real lever for investors: every dollar locked away as a buffer is a dollar unavailable for buybacks, dividend increases, or profitable new business.

A Second Chamber, and a Second Chance

The market is clinging to the fact that nothing is final. The National Council has yet to debate the capital plan, and the larger chamber could swing back toward a more pragmatic compromise. If business lobbyists there succeed in restoring half-credit for AT1 capital, the additional capital need would be cut roughly in half overnight — leaving UBS's earnings power largely intact and limiting the damage to its global competitiveness.

That faint hope produced a modest bounce. The stock closed Thursday at EUR 42.64, up 1.5% on the day. Even after recent declines, the shares sit 38% above their 52-week low, though they trade 12% below the 52-week high of EUR 48.19 — a gap that captures the market's growing unease.

CEO Sergio Ermotti has publicly called the 90% ratio excessive. After the vote, the bank complained that the concerns of business associations, unions and most cantons had been ignored in the upper house.

Public Opinion Is Not on the Bank's Side

The downside risk is real, and it has popular backing. A survey published in June found that 79% of Swiss residents favor stricter capital rules — even if that means lower dividends or slower growth for the bank. Only 9% opposed the idea. Confidence in the sector has also eroded: an industry association study showed trust falling from 75% in 2021 to 53% last year.

Should the National Council hold the upper house's line, or move closer to Keller-Sutter's original 100% demand, the consequences would run deep. Chairman Colm Kelleher has already warned that the bank would have to reconsider its future in Switzerland under overly restrictive rules. Profitability of overseas operations — particularly in the US and Asia — would take a direct hit, and with billions parked in low-yielding buffers, group return on equity would inevitably slide. For shareholders, that would mean a multi-year drought in payouts.

The Operational Story Is a Different Picture

Away from Bern, the integration machine has been running. Ermotti declared the worldwide merger of Credit Suisse essentially complete, with roughly 1.2 million client relationships migrated. The last Swiss customers moved onto UBS's platform in March, clearing the single largest operational risk of the deal.

If the bank can fully extract the synergies, a return to former earnings strength looks achievable. Management is targeting a recovery to 2022 profitability levels by 2028, and a business year described as very good in 2025 has strengthened the underlying foundation. Freed from merger costs, the combined group could move quickly to monetize its global wealth management franchise.

Two Clocks Running at Once

The tension for investors is that these two stories — operational progress and regulatory threat — are now on separate clocks. The decisive marker is the legislative process in Bern. As long as the 90% rule remains a matter of political negotiation, there is room for correction. If parliament's line hardens into law, management will have no choice but to respond.

Media reports from Semafor suggest the board is already revisiting a relocation of the group's headquarters, with a merger with a foreign institution also on the table. Morgan Stanley, Standard Chartered and Deutsche Bank have been floated as theoretical partners. Such a move would be politically explosive and could bring drawn-out friction costs; bank mergers carry enormous execution and integration risks, as recent history has shown.

Watch in the coming weeks whether management prepares concrete legal steps toward a domicile shift. In parallel, upcoming interim reports will show whether cost savings from the completed client migration can offset the regulatory load. Until it is clear how much capital UBS must permanently tie up, the long-term valuation case stays unresolved.
