A global search for yield led fixed-income investors to pad their portfolios with U.S. investment-grade corporate bonds in 2012.
While these bonds have historically experienced low levels of default, they remain exposed to market risk should interest rates spike from their abnormally low levels. The interest rate risk facing corporate bond investors is exacerbated by the high proportion of fixed-rate debt issued of late, which accounted for 96 percent of U.S. corporate bonds sold between September to
A return to higher interest rates will certainly affect fixed- income investors with longer duration bond portfolios, and timing remains key. A number of variables will aid in determining losses for holders of U.S. corporate bonds, but Fitch Ratings notes the speed at which rates will rise is among the most critical.
For instance, if interest rates were to revert rapidly to early 2011 levels (a 200 basis point rise), a typical investment-grade U.S. corporate bond (rated 'BBB' with a 10-year maturity) could lose 15 percent of its market value assuming constant spreads, as explained in Fitch's recent report "The 'Bond Bubble': Risks and Mitigants." An orderly reversion would make for an easier investor landing. If rates rose at a more gradual pace, losses would be mitigated by the coupon income received and the shorter remaining maturity.
Very simply, if a rise in rates were to take place over a one year period, the loss on a typical 'BBB' 10-year U.S. corporate bond might be closer to 9.5 percent. Given a two-year window, the potential loss would be even lower at roughly 3.5 percent. The U.S. Federal Reserve said in
We also note that while a jump in interest rates could translate to significant market value losses, the largest holders of U.S. corporate bonds (U.S. life insurance companies at
