A man stands outside Silicon Valley Bank
Silicon Valley Bank was shut down Friday by regulators.
  • SVB's startup and VC customers are staring down huge losses after its failure.
  • Up to a fifth of the bank's uninsured deposits may not be recovered, according to Moody's estimates.
  • A buyer is being sought for the failed bank by Monday to avoid more calamity for startups. 

The collapse of Silicon Valley Bank could leave startups and tech firms with losses that total billions of dollars.
