The 90% vote reaches the Swiss economy through lending data, and that data does not exist yet

90% · hard CET1 backing for UBS’s foreign units, up from 45%, adopted by the Council of States 29–16¹²

I spent yesterday afternoon with the Reuters wire open on one screen and a set of anonymised Swiss real-asset term sheets on the other. On the first screen, a chamber of 45 people doubled a capital ratio. On the second, nothing moved, and I want to argue that the second screen is the one that matters.

The vote itself was clean enough. The finance minister and the UBS chief executive publicly defended opposing positions in the final round before the chamber decided³, and the chamber then chose the tougher of the two remaining options¹. The current requirement is described as 45% CET1 for the foreign subsidiaries; 90% doubles that percentage².

That is the whole of what was decided: a ratio, in one chamber, on a bill that is not law. Everything else being written about the vote is inference layered on that ratio. Some of the inference is well grounded; the part about the Swiss economy is not.

The dollar figure has been a moving target for fifteen months already

Anyone who has followed this file knows the headline cost has never held still. Laid out in order, the sequence looks like this:

1. The Federal Council’s June 2025 proposal was framed as requiring up to USD 26 billion in extra CET1 at the parent bank⁴.
2. By April 2026 Reuters estimated the softened package at about USD 20 billion of additional CET1, while the government held onto its demand for full capitalisation of foreign units⁵.
3. On 31 August 2026 the upper house committee backed a 50% CET1 / 50% AT1 structure for the foreign-subsidiary requirement, with an extra AT1 trigger at around an 11% CET1 ratio⁶.
4. On 15 September Reuters reported that this compromise could cut the new top-tier capital need to roughly USD 13 billion if AT1 were allowed for up to half of the added requirement⁷.

Then the full chamber rejected the committee’s 50/50 model and took 90%. UBS responded on 23 September that the decision, if confirmed through the full parliamentary process, would force it to hold about USD 33 billion of additional CET1, a figure the bank called “excessive”⁸.

That USD 33 billion is a company number. I found no independent confirmation of it in Reuters, NZZ or Swissinfo; what the reporting establishes is the move from 45% to 90%, and the doubling of the percentage, not the dollar amount². A figure that has travelled from 26 to 20 to 13 to 33 billion inside fifteen months is a measure of the political temperature, and I would not build an allocation view on a thermometer.

The case against the vote deserves its full weight

Sergio Ermotti’s strongest objection is not about the number. He argued that 90% is no real compromise because the 90% and 100% CET1 options are essentially alike in economic effect, that both distort UBS’s competitive position, and that UBS supported the 50% CET1 / 50% AT1 structure because it would cost less to maintain while still addressing the regulatory concern⁹.

Take that argument at face value, because it is a serious one. Hard equity is the most expensive form of capital a bank can hold, and a permanent buffer of that size against foreign units is carried every year, in every market where UBS competes with banks that do not carry it. Reuters frames the whole fight in exactly those terms: lawmakers want to reduce the chance of another Credit Suisse-style rescue, while investors and UBS warn that a very large permanent buffer could hurt the bank’s global competitiveness and potentially its role in the Swiss economy¹⁰.

The disagreement also runs the other way. Karin Keller-Sutter said on 1 September that she was disappointed by the parliamentary softening that preceded this vote¹¹. So the chamber sits between a finance minister who wanted more and a bank that wanted much less, and a 29–16 result on a minority proposal is about as unsettled as a decision can be while still counting as one.

I take the competitiveness argument seriously because I spent a good part of two decades inside the kind of balance sheet it describes. What I do not take on faith is the second half of the sentence, the part where a buffer against foreign units becomes a change in the terms offered on a Swiss commercial property or a Swiss mortgage book. That leap is where the evidence should be, and where it is missing.

What I found in the data, and what I found in my own files

The bill now moves to the National Council. Reuters expects a final decision at the end of 2026 at the earliest and more likely in 2027¹, and I found no verified parliamentary record giving the lower house’s scheduled next reading or the earliest possible enactment date¹². Counting from the vote to the end of 2027 gives roughly fifteen months¹³¹ in which UBS operates under a rule that exists in one chamber and nowhere else.

The question that matters for a Swiss allocator is whether that limbo has already changed behaviour. I found no SNB credit-statistics release and no UBS disclosure showing that the 22 September vote has altered Swiss mortgage or commercial-real-estate lending volume, pricing or rationing; the available reporting describes a future legal requirement, not an observed lending response¹⁴.

The harder version of the question is whether any change could even be attributed if it appeared. Here too I came up empty: I found no SNB banking-statistics release or UBS 2026 filing that compares UBS’s Swiss real-asset lending share, spreads or approval volumes against Zürcher Kantonalbank, the other cantonal banks or the Credit Suisse legacy book in a way that would isolate the capital rule from the SNB policy-rate path¹⁵.

My own files do not fill the gap. Going back through the anonymised Swiss real-asset financings I have sat on since 2023, the variable that visibly moved lender identity, leverage and spread was the rate path, and I cannot point to a single term sheet where I could attribute the shift to bank capital rather than to rates. That is a statement about the limit of what I can see from one desk, and it is exactly as much as I am willing to claim.

The consequence

A capital rule reaches an economy through one channel only: the price and quantity of credit that banks subject to it are willing to extend. A ratio voted in one chamber, contested by the bank, awaited by the other chamber and unlikely to be final before 2027, has not yet touched that channel in any data I can find.

So the number worth watching over the next fifteen months isn’t UBS’s disputed USD 33 billion – it’s whether SNB lending statistics ever show this vote arriving on a Swiss balance sheet at all. If they do, the repricing will show up first in the segments where UBS’s share is largest and cantonal competition thinnest, and it will be visible in public data before it is visible in any press release. If they do not, the Swiss economy will have absorbed the loudest banking debate of the decade without a change in its cost of capital, and that would itself be the finding.

I write from an operator’s desk, and nothing here is investment, legal or regulatory advice. I hold no position in UBS securities, I am not predicting the National Council’s vote, and every allocation decision on the back of this file remains the reader’s own.
