UBS Capital Rules Win a Key Vote, and the Bill Is Billions

Switzerland's upper house of parliament has voted to impose a major new layer of capital requirements on UBS, and the bank has made its opposition clear. On September 23, the Council of States voted 29 to 16 in favor of a draft bill that would require UBS to back its foreign operations with high-quality capital known as CET1, dealing the lender a clear defeat after months of lobbying against the proposed UBS capital rules, according to Reuters.

The vote is the first big parliamentary win for the UBS capital rules overhaul drawn up after the 2023 collapse of Credit Suisse, and it pushes the fight into a new phase. The bill now moves to the lower house, the National Council, with a final decision expected at the end of this year at the earliest and more likely in 2027.

What Bern actually voted for

The UBS capital rules debate centers on how much loss-absorbing capital the bank has to hold against its foreign subsidiaries. The Swiss government wanted UBS to back those units with 100 percent CET1, the purest form of bank capital. The upper house narrowly rejected that option and instead backed a plan requiring 90 percent CET1 backing, according to Financial News.

That outcome sits between two competing ideas. An earlier proposal from the parliament's economic affairs committee would have allowed a fifty-fifty split between common equity and cheaper additional tier one bonds, a compromise UBS preferred. Chief executive Sergio Ermotti said the 90 percent plan was no real compromise and urged lawmakers to support the cheaper AT1 route instead.

After the government-brokered rescue of Credit Suisse in March 2023, UBS became a banking giant whose size worries Swiss regulators. The UBS capital rules overhaul is meant to make sure taxpayers never have to fund another emergency rescue. Finance minister Karin Keller-Sutter has led the push, arguing for the strictest option.

What it costs UBS

UBS has put a number on the damage. The bank said the new rules would force it to hold roughly $16 billion in additional common equity tier one capital, money that would otherwise be available for lending, dividends, or share buybacks. Analysts at Citi and Goldman Sachs put the figure slightly higher, at around $17 billion, and wrote that the rules raise questions about the bank's international competitiveness.

The bank also calculated the annual cost of its 2023 rescue. UBS said its acquisition of Credit Suisse would cost it about $2.5 billion a year if the tough new rules are implemented. In a statement after the vote, the bank said the outcome was not a compromise and failed to address the root causes of the Credit Suisse collapse, adding that it ignored the views of most respondents in the democratic consultation process.

The UBS capital rules vote has already moved the bank's share price. Shares in UBS moved up in European trading on the Wednesday after the vote results, according to a Dow Jones newswire report.

The UBS capital rules debate is unfolding against a mixed market backdrop. Our coverage of the Magnificent Seven's return to record highs and the September wave of Bay Area tech layoffs show how unevenly different corners of the economy are reading the moment.

Ermotti's campaign against the bill

Ermotti has spent months arguing against the UBS capital rules, saying excessive demands would end up being borne by shareholders, customers, and employees rather than making the bank safer. In an interview with the Swiss newspaper NZZ on September 20, he reminded readers of the role UBS played in 2023, saying the bank helped save Switzerland from a reputation-damaging debacle during the Credit Suisse rescue.

He also framed the burden in blunt terms, telling the paper the bank could live with one black eye but that two black eyes and a broken nose would be too much.

The bank is not short of cash. UBS made a profit of $7.8 billion last year and a further $5.8 billion in the first half of 2026, according to the Geneva Times. The bank's argument is not that it cannot afford the build-up but that locking up the capital would put it at a disadvantage against American and European rivals that face looser requirements.

What happens next

The bill now heads to the National Council, where UBS will keep lobbying for the fifty-fifty compromise in the UBS capital rules while the government and the bank's critics push the other way. With a final decision likely landing in 2027, the UBS capital rules fight has a long way to run.

For everyone else, the stakes are simpler. Switzerland is deciding how much insurance its biggest bank should carry under the new UBS capital rules, and who pays the premium. The upper house has given its answer, and the lower house gets the next word.
