In mid-March 2023, Swiss bank UBS Group AG (UBS) bought rival Credit Suisse Group AG for 3 billion CHF (about $3.3 billion USD), a move intended to shore up the global banking system and prevent the latter financial institution from collapsing.

Credit Suisse, one of Switzerland’s leading financial institutions since its predecessor Schweizerische Kreditanstalt was founded in 1856, was among a group of 30 banks known as globally systematically important, and a full collapse might have devastated the global financial system.

Below, we explore what happened with the Credit Suisse crisis and the impact of the bank’s collapse.

About Credit Suisse

As of the end of 2021, Credit Suisse had assets under management (AUM) of 1.6 trillion CHF (about $1.75 trillion), making it the second-largest bank in Switzerland after UBS. At that time, Credit Suisse employed more than 50,000 people. Note that as of year-end 2022, Credit Suisse’s AUM had dropped to about 1.3 trillion CHF (about $1.4 trillion).

Beginning in 2023, Credit Suisse was organized into five divisions: Wealth Management, Swiss Bank, Asset Management, Investment Bank, and Capital Release Unit. At the time of its purchase by UBS, Credit Suisse had about 150 offices in roughly 50 countries around the world.

What Caused the Collapse of Credit Suisse?

Despite its long history, Credit Suisse was plagued by a series of scandals, management shifts, and significant losses in recent years.

In February 2020, Credit Suisse’s then-CEO, Tidjane Thiam, resigned after a 2019 spying scandal. Credit Suisse’s wealth management boss, Iqbal Khan, left for UBS and was subsequently surveilled by private contractors in an effort to determine whether he poached clients.

In 2021, amid the pandemic, the collapse of the U.S. family investment fund Archegos Capital and British finance firm Greensill Capital triggered a pretax loss of close to $1 billion for Credit Suisse. Following the collapse of Archegos, Credit Suisse’s investment bank CEO and chief risk and compliance officer left the company. An independent investigation of Credit Suisse’s role in the Archegos scandal found that the bank had failed to “effectively manage risk,” but suggested that no fraudulent or illegal conduct occurred.

Months later, in January 2022, Chairman Antonio Horta-Osorio resigned from the bank’s board after about nine months in the position over a scandal related to his breaching of Swiss and British COVID-19 quarantine protocols.

By late summer 2022, new CEO Ulrich Koerner unveiled a strategic review that was hindered by an unsubstantiated rumor that Credit Suisse was facing an impending failure. This prompted clients to pull 110 billion CHF (about $119 billion) of funds in the final quarter of 2022.

Facing a stock that shed about three-quarters of its value in a year, Credit Suisse announced plans in early 2023 to borrow up to $54 billion to shore up liquidity and boost investor confidence. However, by mid-March, the bank’s top backer, Saudi National Bank, said it would not give more money to Credit Suisse as a result of regulatory barriers.

One of the final developments prior to UBS’ purchase of Credit Suisse was the collapse of U.S. banks Silicon Valley Bank and Signature Bank in early March 2023. They prompted the U.S. government to make sweeping promises to depositors that money would be available but nevertheless sent fear throughout the global banking system.

Timeline of the Collapse

In summary, the key events leading up to the collapse of Credit Suisse include:

• 2019 and early 2020: Credit Suisse faces a spying scandal regarding an outgoing wealth management executive; then-CEO Tidjane Thiam resigns.
• 2021: Archegos Capital and Greensill Capital collapse, leading to $1 billion in losses for Credit Suisse and another management shake-up.
• Jan. 2022: Chairman Antonio Horta-Osorio resigns from the company following news that he broke COVID-19 quarantine regulations.
• July and Aug. 2022: Rumor circulates that Credit Suisse faces impending failure, prompting clients to pull about $119 billion in funds in the last quarter of the year.
• March 2023: Credit Suisse says it will borrow up to $54 billion from the Swiss National Bank.
• March 2023: U.S. institutions Silicon Valley Bank and Signature Bank fail, setting the global financial system on edge.
• March 2023: Switzerland’s regulatory authorities allowed the takeover of Credit Suisse by UBS without the shareholder approval of either entity.

Impact of the Collapse

The impact of UBS’ takeover of Credit Suisse is wide-ranging. For the bank’s offices around the world and its 50,000 employees, the future remains uncertain, as UBS could absorb some or all of them and shutter or lay off others. UBS is expected to have roughly $5 trillion in AUM following the deal.

The global financial system responded with measures to attempt to stabilize banks. Central banks moved to coordinate daily access to a lending facility for banks seeking to borrow U.S. dollars in the immediate aftermath of the takeover. Switzerland’s government is particularly impacted, as it has agreed to provide 100 billion CHF ($108.4 billion) to ensure the deal is completed. For investors, about 16 billion CHF (more than $17 billion) in Credit Suisse’s contingent convertible bonds are wiped out as part of the takeover.

The collapse of Credit Suisse could also impact Switzerland’s reputation as a stable, strong country for banking. The loss of one of the country’s oldest financial institutions, the bank that bankrolled the construction of Switzerland’s railways, could leave Swiss citizens in and out of the banking industry devastated.

Acquisition of Credit Suisse by UBS

UBS’ purchase of Credit Suisse was orchestrated and approved by regulators. The price tag of more than $3 billion for the deal is modest compared with the size of the bank and its assets. UBS officials also said immediately following news of the purchase that they planned to reduce the size of Credit Suisse in the coming years, potentially by selling off parts of the bank, although details remain scarce.

The Bottom Line

Following several years of scandals, Switzerland’s Credit Suisse bank collapsed in March 2023. It was purchased by Swiss rival UBS for about $3.3 billion in a deal approved by Swiss regulators without shareholder approval. UBS plans to sell off and downsize parts of Credit Suisse in the process. Following the completion of the merger, Switzerland will have only one major financial institution and the country’s reputation for banking stability may have been shaken.
