The acquisition was coordinated by the Swiss government, led by the
Federal Department of Finance, Swiss National Bank, and FINMA. In an emergency meeting on 19 March 2023, the
Swiss Federal Council exercised emergency powers to allow the merger to take place without the approval of shareholders, and to provide Credit Suisse with additional liquidity assistance privileged against bankruptcy and backed by a governmental default guarantee. In addition, the Federal Council granted UBS a guarantee worth CHF 9 billion ($9.6 billion) for potential losses from risks associated with the transaction, after approval by a parliamentary committee. As part of the deal, CHF 16 billion ($17.2 billion) of
AT1 bonds were written down to zero on FINMA's authorizationthe largest writedown of AT1 debt so far. The move forced larger losses on bondholders than on shareholders of Credit Suisse, and was done to placate the international investors unable to vote on the acquisition.
President of Switzerland Alain Berset, Minister of Finance
Karin Keller-Sutter, and Chairman Jordan announced the acquisition in a 19 March 2023 press conference, alongside the chairmen of UBS and CS. The government said that its exposure to risk was low, and considered the acquisition necessary for financial market stability in Switzerland and globally. He further added that the deal was an "emergency rescue".
Sergio Ermotti, who served as CEO of UBS Group from 2011 to 2020, was appointed to lead the Group again, replacing Hamers on 5 April 2023. Kelleher, who was re-elected as chairman, estimated the integration to take up to four years, not including the wind-down of Credit Suisse's investment banking division. According to
Bloomberg News, UBS Group AG is likely to report a profit of as much as CHF51 billion ($57 billion) in the second-2023 quarter related to the negative
goodwill generated by the acquisition of Credit Suisse. The Swiss subsidiary of Credit Suisse alone is said to be worth "multiple times" what UBS paid for it. Credit Suisse Group's
book value was CHF54 billion by the end of March 2023. Later in April 2023, it was revealed the amount of "negative goodwill" would be $35 billion. On June 9, 2023, the contract between the Swiss government and UBS was signed whereas the former agreed to pay UBS up to CHF9 billion ($9.9 billion) should the acquisition of Credit Suisse result in a loss for UBS (the first CHF5 billion will be borne by UBS itself according to the agreement). Only two months later, on August 11, 2023, UBS announced that it ended the CHF9 billion backstop with the Swiss government as well as the CHF100 billion "liquidity backstop" with the Swiss National Bank. According to Swiss Finance Minister
Karin Keller-Sutter, "Swiss taxpayers no longer bare any risk relating to the rescue of Credit Suisse". Less than one month later however, Switzerland was said to introduce a publicly guaranteed "liquidity backstop" for its banks which are "
too big to fail".
Reactions The financial market authorities of the European Union and the United States issued statements in approval of the acquisition. Analysts have described the acquisition as a "
shotgun wedding" arranged by the Swiss government. Credit Suisse CEO
Ulrich Körner said at the April 2023 shareholders' meeting that "We didn't succeed. We ran out of time. This fills me with sorrow". Noting that Credit Suisse had been facing problems for several years, senior editor for
CNN Business Allison Morrow stated, "[Silicon Valley Bank and Credit Suisse are] facing unrelated problems that happened to take place at the same time, worrying investors about the banking sector". Several former executives told the
Financial Times that being almost unaffected by the 2008 crisis caused the 2023 collapse after years of decline, as management thought that the bank did not have to change. Two executives that observers mentioned to the newspaper as contributing to the firm's decline were
Urs Rohner—chairman from 2011 to 2021, during which time Credit Suisse stock declined by 75%—and Romeo Cerutti, general counsel for 13 years until 2022. In Swiss politics, Keller-Sutter's center-right
Free Democratic Party approved of the government's intervention with regret, while the right-wing
Swiss People's Party and the left-wing
Social Democratic Party of Switzerland reacted with anger, denouncing "cronyism" and demanding that those responsible be held to account. The clause of the
Swiss Constitution that the government used to bypass a shareholders' vote allows emergency action "to counter existing or imminent threats of serious disruption to public order or internal or external security". Omitting the vote angered Credit Suisse's large investors; the
Financial Times quoted one from the Mideast as saying "You make fun of dictatorships and then you can change the law over the weekend. What's the difference between Saudi Arabia and Switzerland now? It's really bad". CEO Vincent Kaufmann of
proxy advisor Ethos Foundation, which represents up to 5% of Credit Suisse shareholders, said "This situation is a big failure of corporate governance and may send a poor image of Switzerland for international institutional investors in terms of good governance". While stating that litigation would be difficult, he disagreed with Keller-Sutter's "commercial deal" description: "If you change the law and you remove shareholders' voting power on such a key issue, then you clearly have a state intervention. It's unprecedented and an expropriation of shareholder rights". At the April 2023 Credit Suisse shareholders' meeting, Kaufmann described the firm's collapse as "a debacle without precedent". Octavio Marenzi of Opimas said "Switzerland's standing as a financial centre is shattered. The country will now be viewed as a financial
banana republic". Peter V. Kunz of the
University of Bern said "Foreign investors may wonder if Switzerland is a banana republic where the rule of law doesn't apply", while Kern Alexander of the
University of Zurich said that the "panicked" transaction "undermined the rule of law and undermined Switzerland". At the April 2023 UBS shareholders' meeting, by contrast, there was a sense that the acquisition might be what the
Financial Times called "the deal of the century", although Kelleher emphasized the transaction's difficulty. Both banks' shareholders noted that UBS's balance sheet will be larger than that of Swiss National Bank. A March 2023-survey by gfs.bern research institute found that 54% of the Swiss disagree with the emergency rescue plan of Credit Suisse by the
Swiss government. Sixty-one percent of them would have preferred the state to nationalize Credit Suisse and sell it later. Four out of five respondents want UBS to spin off Credit Suisse's Swiss operations to avoid too much risk concentration and 77% of the Swiss said they are at loggerheads with the management of Credit Suisse over the debacle. In April 2023, the Swiss Attorney General's office opened an investigation to analyze and identify whether any criminal offenses by the government officials, regulators and executives at the two banks, had occurred in connection with the acquisition. The results of the investigation will be sealed for 50 years, longer than the typical 30 for such inquiries.
AT1 bonds issue Analysts warned that UBS-Credit Suisse deal could extend rather than end the banking crisis, mainly because of the write-off of AT1 bonds worth CHF 16 billion.
AJ Bell investment director Russ Mould said: "It means the banking crisis we've seen over the past few weeks has started a new chapter rather than reaching its ending". AT1 bonds from Credit Suisse and UBS are unusual in their terms allowing for total write-off instead of conversion to equity; most such securities have more protections. Both the
Bank of England (BoE) and European authorities stated on 20 March that equity would remain subordinated to debt. According to BoE, "clear statutory order" existed for bank resolutions, in that which AT1 holders would be exposed to losses after equity investors. Former
European Central Bank (ECB) vice president
Vítor Constâncio said that the Swiss AT1 decision was a "mistake with consequences and potentially a host of court cases", and Jacob Kirkegaard of the
Peterson Institute said "A lot of lawsuits will be coming from this, which will highlight the erratic and selfish behavior of Swiss authorities in this saga". the AT1 bonds traded for a few cents on the dollar, implying that investors still see value in them through litigation. Swiss financial regulator
FINMA has however stated that the write down "complied with contractual obligations". Moreover, these bonds provide that they will be completely written down in a "Viability Event", in particular if extraordinary government support is granted. Despite having similar terms to Credit Suisse's AT1 bonds, its $2.5 billion in
Tier 2 bonds were not written off.
FT Alphaville wrote "The best/funniest argument we've heard is that they just forgot about this issue, and by the time someone realised it was best to just pretend this was all deliberate". On 14 October 2025, the
Federal Administrative Court of Switzerland ruled that the write-off of AT1 bonds was unlawful.
Sale price issue Because the emergency takeover on March 19 reduced the value of individual Credit Suisse shares from CHF1.86 on March 17 to CHF0.76 two days later, when the agreement was reached, shareholders claim in court that the bank should have been sold at much higher price (anywhere between CHF7.3 billion to CHF35 billion).
Lawsuits As of October 2023, there were $9 billion worth of claims pending in US and Swiss courts, mostly relating to the AT1 bonds write-off issue. Regarding the claims in international arbitration, Dr. iur. Alexander Lindemann, Founder of Zurich-based
Lindemannlaw firm, observed: "Due to the more than 110 [Swiss bilateral] investment protection agreements and the five-year limitation period in [the Swiss] expropriation law, arbitration courts will be dealing with this issue until at least 2028." ==Impact==
