Several reasons. First, going to ZIRP was stated by the Fed to be "emergency policy". There is no further reason for "Emergency" policy 7 years after the fact.
Second, the Fed has indicated all year that "lift off" was coming. In order to maintain credibility (which is rapidly waning) this was the perfect time to do so.
Additionally, the Fed has stated, several times, that it does not base US policy on the "goings on" of the world and is not beholden to the stock market. Hiking now would have been a step in that direction. After all, it's a measly 25bps.
Thanks for your recommendation. I work in Finance and understand nominal vs. real quite well.
Fixed income is often referred to those who rely on savings and the returns of fixed investments. Not fixed income vs. variable or anything like that. I used the generic term you see when the subject is discussed, and you understood what I meant. Don't get all semantic on me, the point of the conversation is to converse and relay ideas between one another.
The senior on "fixed income" is a lot worse off. That's one of the reasons you see 55 and over going back to work, or not retiring, etc. Heck, a good deal of the employment gains in the past few years were the 55 and older crowd.
