Key paragraph:
> "All insured depositors will have full access to their insured deposits no later than Monday morning, March 13, 2023. The FDIC will pay uninsured depositors an advance dividend within the next week. Uninsured depositors will receive a receivership certificate for the remaining amount of their uninsured funds. As the FDIC sells the assets of Silicon Valley Bank, future dividend payments may be made to uninsured depositors."
The advance dividend presumably should protect most of the small-business account holders from imminently missing payroll. Presumably after that, there will be a secondary market in receivership certificates, and the question will be how much of a discount these trade at relative to the original account balances.
It's still a bad situation to be in, but it shouldn't be as thoroughly catastrophic as many seem to think.
