This was more about a former fed president using the term "risk on" "risk off". He talks about the taper tantrum as well. To me this shows the fed is really paying attention to the market like a trader. good insight on their psychology.
Well, the Fed is concerned about their credibility. And the way we define in economics parlance is credibility is determined by how closely policy matches the rhetoric. If the two don't match, then the value of the rhetoric goes to zero. So the Fed has to walk a tight line between what they say and what they do. Yes, they do watch the market to get a response effect to see how the market is responding to changes but they really discount that a lot because policy choices are meant to be long term and volatility is day by day minute by minute. You can imagine how stupid it would be for the Fed to make a policy decision with a 5 year long term effect based on the dow being down today and then ripping the next 3 months. There really is just too much noise in the market to get a meaningful effect.
