Nominal Value
The value written on the face of the bond. Nominal value is fixed and does never change. It is the basis of accounting records and the redemption plan. It refers to the principal that the bond holder will receive at maturity.
Issue Value
Bonds may be issued at a lower value which may not be less than 5% of their nominal values. In addition, investors who buy the bond prior to the last day of the bond issue, i.e. prior to the inception of interest accrual, may be offered discounts equal to the amount of interest falling onto the early buying date.
Market Value
If the nominal/coupon interest rate of the bond is above the market interest rate, the market value of the bond is above the par (nominal) value. Under this market condition, the bond is traded at premium values.
If the nominal/coupon interest rate of the bond is below the market interest rate, the market value of the bond is below the par (nominal) value. Under this market condition, the bond is traded at discounted values. However, because a bond will enjoy some accrued interest, it generally attains price which is above the par value due to the accrued interest.
If the nominal/coupon interest rate of the bond is equal to the market interest rate, the market value of the bond is equal to the par (nominal) value.
