The Fed can prevent yields from rising through another round of QE. The tradeoff being that it will have to push even more money into the system, undermining confidence in the US economy's ability to operate healthily without serious Fed & government intervention.
I never mentioned hyperinflation because I don't think that's a realistic outcome of more QE. I don't think something, something hyperinflation is a good way to summarize my argument, but it is sure is patronizing, I'll give you that.
Can you provide an argument that explains why we would want more QE at this point?
