How Fed asset purchases reduce yield term premia
An updated Federal Reserve paper suggests that there has long been a link between the net supply of government securities and term premia on Treasury yields. A 1%-point reduction in the ratio of Treasuries or MBS (10-year equivalent) to GDP supposedly reduced the 10-year term premium by 10 basis points. A one-year shortening of the average effective duration would lower the ten-year Treasury yield by about 7 basis points. Based on these estimates, the 2008-2011 large scale asset purchase and maturity extension programs of the Federal Reserve could have reduced the 10-year term premium by a total of 150 basis points.
