Is the term premium driving most of the yield increase?
Core argument: Of the 2.54 percentage point increase in the 10-year Treasury yield since March 2022, 1.56 points — nearly two-thirds — comes from a higher term premium, according to the author's decomposition.
I plot a decomposition of the increase in the 10-year yield into a term premium component and a future short rate component. According to this measure, a big chunk —1.56 pps (or nearly 2/3 rds)— of the 2.54 pps increase in the 10-year yield since March 2022 is actually due to an increase in the term premium. That premium (the red line in the figure) turned negative around 2015, and [when] it bottomed out in 2020, yields (black line) were trading 135 bps below the path of future short rates (blue line). That’s not entirely surprising: The Fed was absorbing a large share of Treasury issuance at the long end of the yield curve —as well as MBS issuance— effectively removing a great deal of interest rate risk from the market.
