On the evening of March 19, 2023, the Swiss government did something that hadn’t been done in living memory. In a hastily arranged press conference, Finance Minister Karin Keller-Sutter announced that Credit Suisse — the 167-year-old pillar of Swiss banking — would be acquired by its rival UBS for 3 billion Swiss francs. The deal was done. There would be no shareholder vote. The decision had been made over a single weekend, behind closed doors, with the Swiss National Bank and the Federal Council overriding normal corporate governance to prevent what they feared would be a catastrophic bank run when markets opened on Monday morning.
Three billion francs. For a bank that had once been worth over 300 billion. For an institution that had financed railways, harbored the wealth of nations, and survived two world wars. The price was less than the estimated value of its Zurich headquarters building.
But the weekend wasn’t the collapse. It was the moment the world realized the collapse had already happened — slowly, then suddenly, across a decade of scandals, misjudgments, and institutional rot that turned one of the world’s most respected banks into a cautionary tale.
Alfred Escher’s Vision
To understand what was lost, you have to understand what Credit Suisse represented. The bank was founded in 1856 by Alfred Escher, a Swiss politician and industrialist who needed a financial institution to fund the construction of Switzerland’s railroad network. Escher envisioned a bank that would serve the nation — financing infrastructure, industry, and commerce. Credit Suisse became the engine of Swiss modernization, and over the following century, it grew into one of the most powerful financial institutions in Europe.
By the late twentieth century, Credit Suisse had evolved into a global banking giant. Its wealth management division managed trillions in assets for the world’s ultra-rich. Its investment banking arm competed with Goldman Sachs and JPMorgan in New York and London. The Credit Suisse name was synonymous with Swiss precision, discretion, and financial conservatism — the very qualities that had made Switzerland the world’s banking capital.
But beneath the veneer of respectability, a series of decisions made in the 2000s and 2010s would set the bank on a path toward destruction.
The Tuna Bonds: Corruption in Mozambique
In 2013, Credit Suisse arranged $2 billion in loans to the government of Mozambique, one of the poorest countries in the world. The loans were ostensibly for a state-owned tuna fishing fleet and maritime security. In reality, much of the money was diverted — kickbacks flowed to Mozambican officials, and over $200 million was skimmed by middlemen and Credit Suisse bankers themselves.
The scandal, which became known as the “tuna bond” affair, was devastating. Mozambique couldn’t repay the loans, the country defaulted on its sovereign debt, and the IMF suspended its aid program. For a nation where millions lived on less than two dollars a day, the consequences were measured in human suffering — schools that weren’t built, hospitals that went unfunded, development that never happened.
For Credit Suisse, the financial penalties were manageable — a $475 million settlement with U.S. and U.K. regulators in 2021. But the reputational damage was profound. This was not a rogue trader or a market bet gone wrong. This was a systematic scheme involving senior bankers at one of the world’s most prestigious institutions, looting a developing nation for personal profit.
Brady Dougan and the Culture of Risk
The transformation of Credit Suisse from a conservative Swiss institution into a risk-hungry investment bank can be traced to the tenure of Brady Dougan, the American who served as CEO from 2007 to 2015. Dougan was the first non-Swiss national to lead the bank, and he brought with him the aggressive, bonus-driven culture of Wall Street.
Under Dougan, Credit Suisse’s investment banking division expanded rapidly. Risk limits were pushed. Complex structured products proliferated. The bank survived the 2008 financial crisis better than many of its peers — it avoided a government bailout, unlike UBS — but the culture Dougan cultivated sowed the seeds for the disasters that followed.
When Tidjane Thiam succeeded Dougan in 2015, he inherited a bank that was profitable on the surface but rotten in its risk culture. Thiam attempted a strategic pivot back toward wealth management and away from investment banking. But his tenure would be cut short by a scandal that had nothing to do with banking and everything to do with the toxic internal politics that had come to define Credit Suisse’s leadership.
The Spy Scandal
In September 2019, Iqbal Khan — a senior Credit Suisse executive who had defected to rival UBS — noticed he was being followed through the streets of Zurich. The followers turned out to be private investigators hired by Credit Suisse’s COO, Pierre-Olivier Bouée, allegedly with the knowledge of CEO Thiam. The bank had been spying on its own departing executive.
The surveillance operation descended into farce when Khan confronted his followers in a public street, leading to a physical altercation. One of the private investigators hired for the operation later died by suicide. The scandal dominated Swiss headlines for months and ultimately forced Thiam’s resignation in February 2020.
The spy scandal didn’t cost Credit Suisse much money. But it destroyed something more valuable: the perception that the bank was governed by adults. Here was one of the world’s premier financial institutions behaving like a paranoid corporation in a thriller novel, hiring gumshoes to tail executives through the streets of Zurich. The board’s handling of the affair — initially defending the surveillance, then sacrificing Thiam when the political pressure became untenable — revealed an institution that had lost its moral compass.
Greensill and Archegos: The $10 Billion Double Blow
Thomas Gottstein, who replaced Thiam as CEO, barely had time to settle into the role before two catastrophes struck in rapid succession.
In March 2021, Greensill Capital — a supply chain finance firm in which Credit Suisse had invested heavily through its asset management division — collapsed. Credit Suisse had been selling Greensill-linked investment funds to its wealth management clients, promising safe, steady returns. When Greensill went bankrupt, $10 billion in client funds were frozen. The bank faced billions in potential losses and devastating lawsuits from clients who had been assured the investments were low-risk.
Just weeks later, Archegos Capital Management — a family office run by former Tiger Management trader Bill Hwang — imploded. Hwang had built enormous, highly leveraged positions in a handful of stocks using total return swaps, a type of derivative that allowed him to avoid disclosure requirements. When those positions began to unwind in late March 2021, the resulting margin calls triggered a fire sale.
Other banks — Goldman Sachs, Morgan Stanley, Deutsche Bank — moved quickly to liquidate their Archegos exposure, limiting their losses. Credit Suisse hesitated. By the time it began selling, the prices had already cratered. The bank lost $5.5 billion — the largest single trading loss in its history. The Archegos disaster wasn’t just a financial catastrophe; it was a management failure. Credit Suisse’s risk controls had flagged Archegos as a high-risk client. Those warnings were ignored.
Suisse Secrets: The Largest Leak in Swiss Banking History
In February 2022, a consortium of international journalists published the “Suisse Secrets” — a massive leak of Credit Suisse account data covering more than 30,000 clients spanning decades. The leak, provided by an anonymous whistleblower, revealed that the bank had held accounts for an extraordinary rogues’ gallery: human traffickers, drug dealers, corrupt politicians, sanctioned oligarchs, and war criminals.
Among the clients identified were a Vatican-linked financier convicted of money laundering, the sons of Egypt’s former dictator Hosni Mubarak, and a businessman implicated in the murder of a Lebanese pop star. The data showed that Credit Suisse’s compliance failures weren’t isolated incidents — they were systemic, spanning decades and touching the highest levels of the bank.
The Suisse Secrets dealt a body blow to what remained of Credit Suisse’s reputation. Swiss banking secrecy, once the industry’s greatest asset, had become its greatest liability — a system designed not to protect privacy but to enable criminality.
The Final Weekend
By early 2023, Credit Suisse was hemorrhaging clients. Wealthy depositors, spooked by the relentless stream of scandals and an increasingly precarious share price, pulled their money in droves. In the fourth quarter of 2022 alone, clients withdrew over 110 billion Swiss francs — a bank run in slow motion.
When Silicon Valley Bank collapsed on March 10, 2023, the shockwave hit Credit Suisse hardest. Although the two institutions had nothing in common operationally, the SVB failure reminded the world how quickly confidence in a bank can evaporate. Credit Suisse’s share price plummeted. Its credit default swap spreads — the market’s measure of bankruptcy risk — soared to levels not seen since the 2008 financial crisis.
On March 15, the Saudi National Bank — Credit Suisse’s largest shareholder — announced it would not invest any additional capital. The statement was technically unremarkable; the Saudi bank had regulatory reasons for its position. But the market interpreted it as an abandonment. Credit Suisse’s shares fell 30% in a single day.
The Swiss National Bank provided a 50 billion franc liquidity lifeline. It wasn’t enough. By Friday, March 17, it was clear that Credit Suisse would not survive to the following week without a buyer. Over the weekend, Swiss authorities brokered the forced sale to UBS — a shotgun marriage between the country’s two largest banks, negotiated under existential pressure in less than 48 hours.
What Was Lost
The collapse of Credit Suisse was not a sudden implosion like Lehman Brothers. It was a slow-motion disintegration — a decade-long series of scandals, each one chipping away at the trust that is the foundation of any banking relationship. No single event killed Credit Suisse. The tuna bonds, the spy scandal, Greensill, Archegos, the Suisse Secrets — each was survivable in isolation. Together, they created a pattern that told the world this was an institution that could not govern itself.
The forced merger with UBS created a banking behemoth managing over $5 trillion in assets — a concentration of risk that made Swiss regulators deeply uncomfortable. Thousands of Credit Suisse employees lost their jobs. Holders of $17 billion in AT1 bonds — a type of contingent convertible debt — were wiped out entirely, sent to zero while shareholders still received something, upending the established hierarchy of capital losses and sending shockwaves through global bond markets.
Alfred Escher built Credit Suisse to serve a nation. A hundred and sixty-seven years later, the nation had to destroy it to save itself.
