Well I’m no bond market trader, from Wiki en.wikipedia.org

The yield and price of a bond are inversely related so that when market interest rates rise, bond prices fall and vice versa.

and

Nominal, principal, par or face amount — the amount on which the issuer pays interest, and which, most commonly, has to be repaid at the end of the term. Some structured bonds can have a redemption amount which is different from the face amount and can be linked to performance of particular assets such as a stock or commodity index, foreign exchange rate or a fund. This can result in an investor receiving less or more than his original investment at maturity.
