/biz/ - Business & Finance

So I'm sure a few of you have been seeing that post circulating around /biz/ today regarding the Fed and what it might be doing with bond yields (capping them and expanding fiscal stimulus). The post went on to explain that the Fed only had two options: Allow bond yields to increase thereby causing a stock market crash, or capping bond yields thereby stabilizing the equities market but simultaneously debasing the currency. I was talking to a friend about this and his comment was "well what if bond yields simply stabilize around where they're at?" After thinking about it I really don't have a good answer especially since I am just starting to delve into what makes the bond markets work. Can someone enlighten me as to what the answer would be to that question and why bond yields must either increase or be capped? Thanks in advance and sorry that this post isn't about cryptocoins.
