Because of this...
It isn't going to be clear for a bit exactly the impact. VC funds and startups who have their account at the bank (and didn't participate in the run ahead of time) may be in bad shape, depending on the particulars when the feds unfold everything.
It could be a factor in a wider SV slowdown, but it's unlikely to singlehandedly start a bay area implosion. Most VCs will be unaffected but I still think this will make it a bad time to start a funding round. Edit: It already was because the market's fucky, no guaranteed money on an IPO.
