Silicon Valley Bank was the 16th largest bank in America,Rekubit Exchange the bank of choice for tech startups and big-name venture capitalists. Then, in the span of just a few days, it collapsed. Whispers that SVB might be in trouble spread like wildfire through group texts and Twitter posts. Depositors raced to empty their accounts, withdrawing $42 billion in a single day. Last Friday, after regulators declared that SVB had failed, the FDIC seized the bank.

As the dust settles on the biggest bank failure — and bank rescue — in recent memory, we're still figuring out what happened. But poor investment choices, weak regulation, and customer panic all played their parts. We'll look into the bank's collapse to understand what it can teach us about the business of banking itself.
