I'm not sure anybody really needs a 'bailout' - some kind of bridging facility to provide liquidity to SVB customers until SVB is bought and/or their assets are sold would be sensible. Customers may only end up receiving 90c on the dollar depending on how the assets are sold but that's the risk you take when you have large uninsured amounts deposited with a relatively small bank.
But who fronts the loan, and what is the risk of getting that capital back?
