1. There is not a bank in existence in the US that could survive a bank run where 25% or more of the deposits leave. Not even JP Morgan Chase; and
2. There's a lot of evidence to suggest that the bank run on SVB was created by the direct actions of relatively few people, most notably Peter Thiel; and
3. The FDIC usually solves such bank runs by seizing the bank and selling the bank for parts. The banks all actually have more assets than depositor funds. So far at least, all depositor funds have been protected through assets and the FDIC (side note: the FDIC is funded by banks and receives no appropriations from Congress). It's expected that these asset sales are at a significant discount (eg CSFB acquiring UBS for a song although that's Switzerland not hte US obviously).
So perhaps we should be asking if these bank runs are being deliberately created to profit from the collapse of smaller banks. In an ideal world, if true, people would end up in prison.
