Credit Suisse: How A 167 Year Old Bank Died In One Weekend
Credit Suisse was founded in 1856 to help fund the building of Switzerland's railways. It survived two world wars, the Great Depression, the oil shocks, the dotcom crash and the 2008 financial crisis. It was one of roughly thirty banks classed globally as too important to be allowed to fail.
On Sunday the 19th of March 2023, it was sold to its great rival UBS for three billion Swiss francs in a deal hammered out over a weekend by the Swiss government, the central bank and the regulator, purely so that something could be announced before markets opened on Monday.
That is how fast a 167 year old institution can disappear.
The story matters far beyond Switzerland, because Credit Suisse was not brought down by one catastrophic trade or a single rogue employee. It was brought down by years of scandals, each one absorbed, apologised for and survived, until the day customers stopped believing the apologies.
Understanding that sequence tells you something important about how modern money actually works. In banking, the product is not really loans or accounts. The product is confidence. And confidence, once it goes, goes very quickly indeed.
To see why nobody trusted Credit Suisse by 2023, you have to look at the years before it.
In 2019 the bank was caught up in an extraordinary scandal after it hired private investigators to follow a senior executive who was leaving to join UBS. The surveillance became public, an internal inquiry followed, and eventually chief executive Tidjane Thiam resigned. A bank built on discretion had been caught tailing its own staff through the streets of Zurich.
In March 2021 the bank was hit twice in quick succession. First Greensill Capital, a supply chain finance business, collapsed, freezing around ten billion dollars of client money held in funds Credit Suisse had marketed to investors. Then Archegos Capital Management, a family investment office using enormous borrowed leverage, imploded, costing Credit Suisse roughly 5.5 billion dollars. Other banks exposed to Archegos got out faster and lost far less. Credit Suisse was the slowest and paid the most.
In 2022 came the moment that should have ended all doubt. A Swiss criminal court convicted the bank over failures to prevent money laundering connected to a Bulgarian cocaine trafficking network, the first time a major Swiss bank had faced a corporate criminal conviction of that kind at home. That same year, a leak of client data raised questions about accounts linked to criminals and human rights abusers, and the bank had already paid out hundreds of millions over hidden loans to Mozambique in the so called tuna bond affair.
Any one of these would be a serious scandal. Together they built a picture of an institution that took the profit and treated the fines as a cost of doing business.
By the end of 2022 the damage was showing where it counts. Clients pulled more than one hundred billion francs out of the bank in a single quarter. Wealthy customers, the very people a Swiss bank exists to serve, were quietly voting with their feet.
Then in March 2023 two things happened within days. Credit Suisse delayed its annual report and admitted material weaknesses in its financial reporting. And the chairman of its largest shareholder, Saudi National Bank, was asked on television whether he would provide more money. His answer was blunt and public: absolutely not.
That was the match on the petrol. Withdrawals accelerated into a full run, and regulators later revealed the bank came close to breaching the minimum cash levels it was required to hold at the Swiss National Bank. No amount of capital on paper saves you when everybody wants their money on the same afternoon.
The rescue itself created a second scandal. As a condition of the deal, the Swiss regulator FINMA ordered around 16.5 billion francs of Additional Tier 1 bonds, a form of bank debt, to be written down to zero, while shareholders still received UBS shares.
That inverted the natural order. Bondholders are supposed to rank above shareholders when things go wrong. Roughly 3,000 investors launched hundreds of legal challenges, and in October 2025 the Swiss Federal Administrative Court ruled the write off had no proper legal basis. FINMA is appealing to the Supreme Court. Years on, the money is still in limbo.
So what does a Swiss bank's death teach a saver in Britain?
The first lesson is the harshest. A bank run no longer looks like queues outside branches. It looks like taps on a phone screen. Money can now leave an institution faster than any bank can raise it, which means the gap between "there are some concerns" and "it is gone" can be a matter of days. Never assume that age, size or reputation guarantees survival.
The second lesson is about protection you may already have and never checked. In the UK, the Financial Services Compensation Scheme covers deposits with UK authorised banks, building societies and credit unions. That limit rose from £85,000 to £120,000 per eligible person, per authorised firm, on the 1st of December 2025, the first increase since 2017. There is also cover of up to £1.4 million for six months on temporary high balances, which matters if you have just sold a house or received an inheritance.
The catch that trips people up is the phrase "per authorised firm". Several familiar high street brands share a single banking licence, so holding money in two names from the same group can leave you with one lot of protection, not two. It takes ten minutes to check, and it is the single most useful thing most people could do with their savings this week.
The third lesson is for investors. Credit Suisse AT1 bondholders were paid a high rate of interest for years. That yield was not generosity. It was payment for accepting the risk of being wiped out, a risk written into the small print that many either did not read or assumed would never be triggered. If something pays noticeably more than everything around it, the extra return is always compensation for a danger you have not fully priced.
And the last lesson is the simplest. Reputation is not a soft, fluffy thing that sits alongside the numbers. For a bank, it is the entire business. Credit Suisse spent years treating scandals as expensive inconveniences, and then discovered that trust, once spent, cannot be borrowed back at any price.
