Signature Bank's failure took only marginally longer. "The number 36 has just been, you know, branded in my brain," Atlanta Fed President Raphael Bostic told Reuters earlier this month. "I think that any time you have a bank failure like this, bank management clearly failed, supervisors failed and our regulatory system failed," Barr told U.S. lawmakers in a hearing in March. "It's how do we allow a bank whose failure threatened the financial system to persist without being subject to more aggressive intervention?" "One thing for certain ... this was a very significant supervisory failure," Tarullo said at the Peterson Institute for International Economics event on Wednesday.
