Monetary Policy Report submitted to the Congress on July 18, 2007, pursuant to section 2B of the Federal Reserve Act
Figure of spreads of corporate bond yields over comparable off-the-run Treasury yields, by credit rating, 1998-2007
Data are plotted as three curves. The high-yield bond spread fluctuates between 2.6 percent and 8.4 percent. It begins around 3 percent in 1998, rises to about 6 percent in late 1998, and then generally rises to peak near 8 percent several times: in 2000, 2001, and 2002. It then generally falls to just under 4 percent by 2004, where it fluctuates within a relatively narrow range through mid-2007. The BBB and AA spreads exhibit similar patterns but fluctuate within narrower and lower ranges: the BBB between 0.7 percent and 3.2 percent and the AA between 0.4 percent and 1.5 percent.
Note: The data are daily and extend through July 13, 2007. The spreads shown are the yields on ten-year bonds less the ten-year Treasury yield.
