You have a business with 50 or more employees these days, and you'll probably need to have $250,000 in a liquid account just to cover your payroll every two weeks.

The problem at Silicon Valley Bank is compounded by its relatively concentrated customer base. In its niche, its customers all know each other. And Silicon Valley Bank doesn’t have that many of them. As at the end of 2022, it had 37,466 deposit customers, each holding in excess of $250,000 per account. Great for referrals when business is booming, such concentration can magnify a feedback loop when conditions reverse.
The $250,000 threshold is in fact highly relevant. It represents the limit for deposit insurance. In aggregate those customers with balances greater than this account for $157 billion of Silicon Valley Bank’s deposit base, holding an average of $4.2 million on account each. The bank does have another 106,420 customers whose accounts are fully insured but they only control $4.8 billion of deposits. Compared with more consumer-oriented banks, Silicon Valley’s deposit base skews very heavily towards uninsured deposits. Out of its total $173 billion deposits at end 2022, $152 billion are uninsured.
