How to Find a Default Risk Premium on a Corporate Bond

by Ryan Menezes ; Updated April 19, 2017
Bonds are surer investments than stocks, but they still present risks.

Financial markets offer a standard real risk-free rate of interest, one equivalent to the rate the Treasury extends on its inflation-protected securities. Corporate bonds offer higher rates. The increased returns compensate investors for risks and costs associated with the investment. The default risk premium, one component of the increased returns, takes into account the risk that the corporation will declare bankruptcy before the bond matures. Corporations, unlike the U.S. government, represent a significant risk of default, and the default risk premium serves as a balance against the potential for loss.

Step 1

Subtract the Treasury rate on inflation-protected securities from the corporate bond's annual percentage yield. For example, if the Treasury offers a 0.3 percent rate on 10-year securities and the bond offers a return of 7.6 percent, subtract 0.3 from 7.6 to get 7.3 percent.

Step 2

Subtract from this difference the predicted inflation rate over the bond's life, which forms the bond's inflation premium. For example, if this annual rate is 4.2 percent, subtract 4.2 from 7.3 to get 3.1 percent.

Step 3

Subtract from this difference the bond's listed liquidity premium. The liquidity premium compensates investors for the liquidity they lose in converting their cash to the fixed bond. For example, if the bond offers a liquidity premium of 2.0 percent, subtract 2.0 from 3.1 to get 1.1 percent. This value is the corporate bond's default risk premium.
