SVB - extremely poorly run regional bank
First Federal - huge % of their deposits were uninsured (above FDIC limit) which, if you know anything about banking, are generally seen as 'hot' money and are typically much more likely to be pulled at a moment's notice, which puts the bank's regulatory reserves at risk.
Big banks are not at risk as the 08-09 fiascos made the Feds clamp down very hard on them. Regional banks can get away with mismanagement a lot easier.
No way of knowing but very doubtful this is systemic to the entire banking industry. Two examples of how not to run a bank blowing up.
