Several said that if SVB didn't get 100% depositor coverage that they would assume any regional bank could fail, and thus everyone should move to something safe like JP Morgan. By the time they started to say this publicly they already instructed portfolio companies move out of regional banks. Many were in the process of doing so.
The Fed / FDIC can see this happening and now are over a barrel. So the VCs managed to start one run, then jump up and down yelling to be saved OR ELSE we are going to actively start a series of runs by undermining trust. It's super cynical, and basically allowed the banking system to be held hostage.
Now I am not someone who thinks there shouldn't be some kind of action to help out depositors. For me the biggest issue is cash flow, and if uninsured depositors can be helped very quickly to make sure their businesses don't fail (because they can, SVB has the assets) then the government should make that happen. But somehow that wasn't good enough for the VCs. They yelled that its 100% secured deposits or nothing. And it's really uncomfortable that we allow them to have that kind of leverage.
