I think inverted yield curve is interesting. In my simplistic understanding, isn't it just a global bet that short term yield is going better than the long term based on investor sentiments. So in essence, when the inversion happens, the smart money is on a downturn/recession. I believe that the 10 year bond and the 2 year bond yield have been close recently feeding fears of an inverted yield curve and recent talk of a downturn.
