Yes, it's share holders who will realize the loss. Anyone owed money by the bank, ie depositors is now in a line to be paid as the FDIC sells everything and pays out the obligations.
Depositors will get a “special dividend” next week which is about 50% of their deposits. The other 50% will be coming as they sort out and sell the assets which would take a couple of months.
The 250k FDIC limit is just what they guarantee. If the bank has enough assets left they will pay over the limit to make depositors as whole as possible. Plenty of information on this topic in threads over the last few days.
The 250k will happen Monday and is not in question, the rest will come in bits via special dividends as they sell assets, it may or may not reach 100% of deposits over time.
If the fdic has any sense they’ll announce up front the exact figures though and announce it is close to 100% for depositors to make sure this is contained, ideally through a sale to another bank, if not they’ll have to run it. Bondholders and shareholders and svb employees get wiped out.
The bank has long term bonds that they loaded up on during the Covid interest rate lows. It's not possible for the uninsured depositors to get anything near 100% of their deposits since these bonds have lost much of their value. Unless there is a bailout, no depositor is getting anything near 100%.
75% of depositors had less than $250k on account and every one of these accounts will get all of their money tomorrow. The rest of the depositors will get $250k tomorrow and most of the rest of their money later.
