Risk Free - Equity Risk = Free Equity?

Felix Salmon notes how Moody's is now splitting their sovereign Triple-A ratings into 3 categories... Resistant, Resilient and Vulnerable... and that the US is only in the middle bunch (along with the UK... Some special relationship, eh?!)

So now there's something less risky than risk-free!

Great news for those still using the Equity Risk Premium to justify high stock price valuations... pick your own risk-free rate!

------------

It's always mystified me that the ERP was seen as the return "required" above the risk free rate historically, and therefore a justification for current or future prices. Isn't it basically a circular argument? Or at best just a tool for relative value trades or reversion-to-mean type calls?
