This is exactly the statement that's required, given the confusion and irresponsible politicization of deposit insurance. Shareholders lose 100%, depositors get 100% of their deposits back. It's a simple situation, and the former point (as opposed to the solution during the GFC) counteracts moral hazard.
What politicization of deposit insurance? The amount of deposits that are insured have been capped since the program was put in place 90 years ago. Making all depositors completely whole is not insurance. That was not a risk that premiums were paid for. It’s a government bailout.
While it's well and good in theory that deposits are capped at $250k, adhering strictly to that rule right now will cause cascading consequences much more serious than the price of this guarantee.
Sensible realpolitik right now is to guarantee the deposits to prevent cascading wealth destruction that will very much hit Joe Average, then adapt the system to prevent moral hazard and ensure that this insurance premium is collected in the future. There will probably be a way to recoup the cost of the guarantee from debt holders to SVB, but right now the real concern is putting out the burning crisis of confidence.
