yield spread

The difference in yield, at a given time, between two bonds or between different segments of the bond market. For example, the yield spread between AAA-rated bonds and A-rated bonds may be one half of 1% at a particular time. Likewise, the yield spread between long-term taxable and nontaxable bonds may be 2%. Yield spread may be caused by any of various factors including maturity difference, risk difference, or taxability difference.

Yield spread. Yield spread describes the difference between the yields on two different debt instruments. For example, you can calculate the yield spread on two bonds, by subtracting the yield on one bond from the yield on the other.

Yield spread is helpful in comparing bonds with different maturities, credit ratings, and tax status. In general, securities with longer maturities tend to have higher yields than those with shorter maturities. And securities with higher credit ratings have lower yields than those with lower ratings.
