Is there any reason the FDIC itself cant just hold onto the bonds until they mature? The federal government doesnt need liquidity the same way a bank does, they wouldn't need to sell them for less than face value. Edit: this is actually a serious question, if someone knows the actual answer. I understand that ideally the government wouldn't want to hold onto the bonds, but is there any statutory (or other real) reason why they would _have_ to sell them at less than face value? If you could guarantee 100% of deposits could be returned by just holding onto the bonds until maturity, that seems like a worthwhile trade.
