As you can see, we're nowhere near the number of banks that could collapse, but, with the collapse of FRB, we've passed the total AUM of banks which collapsed during the height of the '08 GFC. So, that's a little staggering...
Personally, I'm not expecting any others to collapse, but I also wouldn't be surprised to see up to five more. Moody's downgraded six banks when SVB collapsed - one was FRB. All of the others seem to be doing okay for now, but only one (Western Alliance) is trading higher than its price at time of downgrade.
