IMO, guaranteeing that the banks can use savings deposits to save the banking system from a crash won't work in the long run. The banks will see it as an opportunity to increase profits by issuing more loans against their existing reserves, which must happen simply because they are competing against each other. The system can still crash and it will be much bigger. We need to send a message by passing laws that block this IMF predatory behaviour and anything else that resembles it.
