Bank failure

The Federal Reserve Building in Washington, D.C. 

Just over a year before Silicon Valley Bank’s collapse threatened a generation of technology startups and their backers, the Federal Reserve Bank of San Francisco appointed a more senior team of examiners to assess the firm. They started calling out problem after problem.

As the upgraded crew took over, it fired off a series of formal warnings to the bank’s leaders, pressing them to fix serious weaknesses in operations and technology, according to people with knowledge of the matter.
