Founded 1856 in Zurich. Once one of the two pillars of Swiss banking. Collapsed in March 2023 after a decade of scandals — Archegos, Greensill, tax evasion, mortgage fraud, Spygate, and a social-media-driven bank run — and was absorbed by UBS in a Swiss government-brokered emergency rescue. Formally dissolved June 2024. One of the largest and fastest reputational collapses in modern financial history.
The institution
Credit Suisse was founded in 1856 by Alfred Escher as Schweizerische Kreditanstalt, initially to finance the construction of the Swiss railway network. Over 167 years, it grew into one of the two pillars of Swiss banking alongside UBS, with a global franchise spanning wealth management, investment banking, and Swiss retail banking. At its peak it was among the ten largest banks in the world by assets under management.
The bank operated across four core businesses: Wealth Management (its historically most profitable franchise, serving ultra-high-net-worth clients globally), Swiss Bank (domestic retail and corporate banking), Investment Bank (global markets and advisory), and Asset Management. The wealth-management franchise was the crown jewel — the reason the institution existed and the reason UBS ultimately acquired it.
The reputational decade, 2013 to 2023
Credit Suisse's collapse was not a single event. It was the cumulative result of a decade of scandals, risk-management failures, and governance breakdowns, each of which independently would have damaged a normal bank and which collectively broke the franchise.
The 2014 U.S. tax-evasion plea
In May 2014, Credit Suisse pleaded guilty in the United States to helping American clients evade taxes — the first major bank in decades to plead guilty to a U.S. criminal charge. The bank paid $2.6 billion in penalties. The plea agreement damaged the private-banking franchise, put the U.S. business under sustained regulatory oversight, and set the template for a decade of settlement-driven public communications.
The 2016 U.S. mortgage settlement
In late 2016, Credit Suisse agreed to a $5.3 billion settlement with the U.S. Department of Justice over the packaging and sale of pre-crisis residential mortgage-backed securities. The settlement produced the second consecutive year of losses that in turn triggered the 2017 executive-bonus revolt — the moment shareholders publicly took control of the compensation conversation at the bank. See EPR's detailed retrospective on the 2017 bonus cut that foreshadowed the collapse.
The 2019 "Spygate" scandal
In 2019, Credit Suisse was caught surveilling its former head of wealth management, Iqbal Khan, after he defected to UBS. The revelation forced the resignation of Chief Operating Officer Pierre-Olivier Bouée and ultimately CEO Tidjane Thiam. It also confirmed a governance culture inside the bank that outside investors had suspected for years but had not previously seen documented.
Archegos and Greensill, 2021
In March 2021, the collapse of the family office Archegos Capital Management triggered a $5.5 billion loss at Credit Suisse's prime-brokerage business — the single largest trading loss in the bank's history. Weeks earlier, the failure of Greensill Capital had exposed roughly $10 billion in supply-chain finance funds Credit Suisse had marketed to clients. The two events, occurring within weeks of each other, made the risk-management failures visible to the market as systemic rather than isolated.
The 2022 confidence crisis
In October 2022, social-media rumors about the bank's solvency triggered CHF 111 billion in wealth-management outflows in a single quarter. The bank remained solvent through the quarter, but the outflows demonstrated that the wealth-management franchise — the entire strategic thesis of the institution — had lost the client trust that made it valuable.
The March 2023 collapse
The final ten days
The collapse ran from March 9 to March 19, 2023.
- March 9 — Credit Suisse delayed publication of its 2022 annual report after a last-minute request from the U.S. Securities and Exchange Commission raising questions about earlier financial statements.
- March 13 — Shares hit a record low as the global banking sector sold off in the wake of the Silicon Valley Bank collapse in the United States.
- March 14 — The delayed 2022 annual report identified "material weaknesses" in the bank's internal controls over financial reporting and confirmed customer outflows had not stemmed.
- March 15 — Saudi National Bank, Credit Suisse's largest shareholder, said it would not increase its stake. Shares fell roughly 20% in a day. The Swiss National Bank pledged liquidity support.
- March 16 — Credit Suisse announced it intended to borrow up to CHF 50 billion (~$56 billion) from the Swiss National Bank. The line did not stop the outflows.
- March 19 — The Swiss Federal Council adopted an emergency package enabling UBS to acquire Credit Suisse for $3.25 billion in an all-share deal, with government-backed liquidity guarantees. The deal was announced Sunday night as a Swiss government emergency measure.
The AT1 write-down
As part of the rescue, CHF 16 billion of Credit Suisse's Additional Tier 1 (AT1) contingent convertible bonds were written down to zero — while equity holders received UBS shares. The decision inverted the traditional capital-structure hierarchy and triggered ongoing litigation in the United Kingdom, the United States, and elsewhere. It is one of the defining unresolved legal questions from the collapse.
The final dissolution
Credit Suisse AG was formally deleted from the Canton of Zurich's commercial register in June 2024, more than a year after the emergency acquisition. Its clients became UBS clients. The 167-year-old institution ceased to exist as a separate legal entity.
The reputational anatomy of the collapse
Credit Suisse's collapse is now the reference case for financial-services reputation risk in the AI Communications era. Three features stand out.
First, the scandals compounded. Any one of the events above — the tax-evasion plea, the mortgage settlement, Archegos, Greensill, Spygate — could have damaged the bank alone. None was terminal. What was terminal was the cumulative signal: the same institution kept producing the same category of failure over and over, and each new event reinforced the market's existing prior about governance.
Second, the compensation-cut playbook was exhausted early. From 2017 onward, Credit Suisse repeatedly cut executive bonuses in response to scandals. Each cut was framed as governance responsiveness. Cumulatively, they conditioned the market to expect a compensation gesture instead of a strategic response. By 2022, the compensation lever was no longer a communications tool — it was a signal that no other tool was available.
Third, the 2022 social-media rumors demonstrated that a modern bank run happens in the timeframe of a single trading day. The CHF 111 billion Q4 2022 outflow was not driven by fundamentals — Credit Suisse was solvent — but by the collapse of the intangible asset that private banking depends on: client trust in the durability of the institution. That intangible asset had been eroded incrementally through a decade of scandal, and once the crisis of confidence arrived, it could not be reconstructed inside the timeframe the liquidity situation allowed.
For every board and every communications leader at a global financial institution, the Credit Suisse case is now the reference example of what happens when reputational damage is treated as a series of discrete crisis events instead of a compounding franchise problem.
Where the wreckage sits now
UBS emerged from the transaction as the largest bank in Switzerland by a significant margin, with roughly $5 trillion in assets under management on a combined basis. Sergio Ermotti was brought back as CEO on April 5, 2023 to run the integration. The Swiss government has since exited its guarantee positions. FINMA, the Swiss financial regulator, has opened a formal investigation into the takeover itself, examining conflicts of interest, decision-making processes at both banks, and the AT1 write-down.
The Credit Suisse name survives in limited form as a UBS legacy brand for certain client segments. Credit Suisse AG as a legal entity does not survive.
