Credit Suisse’s fatal bank run points to gaps in liquidity rules

BLOOMBERG 

Credit Suisse AG was hit by renewed outflows over several days in March that took it to the brink of bankruptcy, even when it was supposed to have enough funds to cover a month of deposit flight.
As Swiss officials and Credit Suisse executives emphasised that the firm’s emergency sale staved off imminent collapse, they highlighted how sharp the run was. The bank had 120 billion francs at the end of December to cover the 83 billion francs of net outflows it expected over a brutal 30 days, and said that as of March 14, that ratio had improved. But just a few days later, it was on the brink.
That’s thrown into spotlight just how prepared lenders are to weather a crisis and return money to depositors on demand. Swiss Finance Minister Karin Keller-Sutter and Marlene Amstad, head of Swiss financial watchdog Finma, both indicated that Credit Suisse was teetering on the brink of bankruptcy at the time of its government-backed rescue on March 19. Amstad said Credit Suisse suffered an “unprecedented” bank run at a press conference.
Regulators are reviewing how quickly depositors not covered by an insurance scheme can pull their money when doubts emerge about a bank’s viability, Bloomberg has reported. There’s a growing consensus that previous estimates putting the so-called runoff rate as low as 10% among retail deposits is obsolete because of how quickly destabilising rumours can spread on social media, as well as the ease with which money can be moved.
The 167-old lender was forced into an emergency weekend takeover even though Swiss authorities said that it met all regulatory capital and liquidity requirements. Finma said it had begun to ratchet up demands on the lender a few years ago, having asked for higher liquidity buffers from Credit Suisse as early as 2020.
On the day of its rescue, Finma had prepared a bankruptcy plan for Credit Suisse, Amstad said. Allowing the bank to fail would likely have wreaked havoc on financial stability by triggering runs at other banks. That, she said, was the main reason for Finma to advocate for a rescue.
The second bank run at Credit Suisse happened after a first rush to withdraw funds in October 2022, when it lost 84 billion Swiss francs in client money over the span of just a few weeks. The lender subsequently failed to persuade clients to return their cash, and the depletion of liquidity meant it had less to fall back on when depositor panic again flared up in March.
Of course, the flipside is that if banks are forced to hold more cash, it limits their profitability, which may slow the buildup of capital buffers and lead to more concern about their financial position. And some securities that qualify as “high-quality liquid assets” for liquidity rules are government bonds that dropped sharply in value last year.
The liquidity coverage ratio is a regulatory metric designed in the aftermath of the financial crisis to ensure banks can withstand short-term bouts of severe stress.
