Why Bonds Trade at par, Discount, or Premium

Posted on 06.12.12 in category Investments

Here is a quick reference chart to help you determine market price and coupon rate of bond trades.

- When a bond trades at par value:
- Market Price = face value
- Coupon Rate = market interest rate

- When a bond trades at a discount:
- Market Price < face value
- Coupon Rate < market interest rate

- When a bond trades at a premium:
- Market Price > face value
- Coupon Rate > market interest rate

Bond Pricing Principles

- Interest rates and bond prices are inversely related.
- The longer the time a bond matures, the more volatile the market value of bond in response to changes in interest rules.
- Lower coupon bonds are more volatile in price than higher coupon bonds when interest rate changes.

- Lower coupon –> greater % in future = volatility
