This arrangement usually results in all depositors being made whole, and the FDIC fund not taking any, or many, actually losses, because most of the loans will still pay back, at least partially
They also do this before seizing the bank, so that it's all very orderly and calms any panics
SVB was looking for a buyer on the open market and that failed--no surprise
That the FDIC also could not find a buyer that they could subsidize and announce the same day as the seizure is very damning. I would be shocked if someone comes in later and tries to buy it
Also, the fact the seizure happened in the middle of the business day, and not at the close of business yesterday points to a somewhat disorderly and rapidly deteriorating condition. I think maybe the run picked up a lot faster than they expected
