(New York) The American authorities took control of the regional bank First Republic on Monday and sold the vast majority of it to JPMorgan Chase, hoping to close the episode of banking crisis that emerged in March.

The institution had been under severe pressure since the close failures last month of two institutions with a similar profile, Silicon Valley Bank and Signature.

But First Republic failed to come up with a satisfactory rescue plan, and when it confirmed last Monday that scores of customers withdrew more than $100 billion in deposits in the first quarter, its already struggling stock took a hit. of the nose.

The authorities, who seemed reluctant to come to the rescue of a third bank in a short time, finally stepped up, soliciting offers from financial institutions before officially seizing First Republic.

This is the second largest bank failure in the history of the United States (excluding investment banks like Lehman Brothers) after that of Washington Mutual in September 2008.

The assets of the latter had also been largely acquired by JPMorgan which, under the leadership of its boss Jamie Dimon, has several times rescued institutions in difficulty.

Under Monday’s deal, the country’s biggest bank will take back all of First Republic’s deposits and nearly all of its assets, while its branches can reopen on Monday as usual.

“Our government invited us and others to intervene, and we did,” Jamie Dimon said in a statement. The operation makes it possible, according to him, to “ minimize the costs ” for the deposit insurance fund.

The deal does mean that First Republic’s loans are to be downgraded, and the agency responsible for guaranteeing the deposits, the FDIC, has agreed to cover some of those losses: it believes the deal will cost it about $13 billion, a sum that will come from contributions paid by the banks.

The Ministry of the Economy said it was “encouraged” by the solution found and, in a statement, assured that the American banking system remains “healthy and resilient”.

The authorities and other major banks intervened in March to prevent First Republic from meeting the same fate as SVB and Signature, with eleven financial institutions agreeing to deposit a total of $30 billion there.

But that was not enough to reassure.

First Republic, founded in 1985 and based in San Francisco, was only worth $654 million on the stock market on Friday, compared to more than $20 billion at the start of the year.

The FDIC and the Department of Economy approached several banks mid-last week to gauge their interest and on Friday granted a handful of them access to First Republic’s detailed accounts.

The bidding process was “ very competitive ” and resulted in a transaction “ compliant with the requirements of least cost ”, assured the FDIC.

First Republic might seem attractive: it was known for having a wealthy clientele, depositing large sums into accounts and repaying loans well.

But many of its customers took fright after the bankruptcies of SVB and Signature. And it had a number of mortgages and fixed rate investments in its accounts, which mechanically lost value with the recent rise in interest rates.

The question now is whether the bankruptcy of First Republic will lead to others in a sector shaken by rising interest rates.

Observers were worried about a risk of contagion after the failures of March, which also created turmoil across the Atlantic and accelerated the fall of Credit Suisse.

But these fears have eased somewhat after the publication in the past two weeks by several small and medium-sized banks of solid financial statements.

“ First Republic was identified as a problem bank in mid-March and the announcement of its closure does not constitute a new reason for concern ”, estimated Nicolas Veron, economist for the think tanks Peterson Institute for International Economics and Bruegel, before the formalization of the bankruptcy. “If another bank turned out to be fragile, that would be another problem,” he added.
