No, SVB is in receivership because they can make their depositors whole right now. They have most of the assets, it’s just that liquidating them immediately would result in losses far greater than SVB can afford, but that’s what a bank run demands.
The feds can take over, make depositors whole now by funding deposits from federal funds, while taking on SVBs assets and liquidating them on a timeline that maximises the value, ideally a value that covers all depositor funds.
In effect the feds provide a loan to SVB depositors, backed by SVB assets. Which is far better than either forcing the FDIC to actually payout the insured amount, because depositors get their funds, and the fed avoid having to handover cash to SVB to keep them afloat. Meanwhile shareholders take a bath, because their shareholding value drops to zero.
