Par Value

Par value is the face value of a bond—the amount printed on the certificate (if it were physical). A bond with a $1,000 par value means the company promises to return $1,000 when the bond matures. The coupon payment and yield calculations all flow from par value, making it the anchor of every bond’s arithmetic.

How par value works

When a company issues a bond with $1,000 par value and a 5% coupon, it promises:

• To pay $50 per year in coupon payments (5% × $1,000)
• To return the full $1,000 at maturity

Par value is typically $1,000 for institutional corporate bonds, though some older bonds used $500 or $10,000. When a bond is first issued at par, you pay $1,000 and receive $50 per year in interest.

Par vs. market price

Par value is fixed, but the bond’s market price fluctuates with interest rates and the issuer’s credit rating. If rates rise after issuance, the bond’s price falls below par (a discount), because new bonds offer higher coupons. If rates fall, the price rises above par (a premium).

For example, imagine you bought a 5% coupon bond at par ($1,000). If interest rates rise to 6%, new bonds offer 6% coupons. Your 5% bond is less attractive, so its market price drops to ~$960 to yield the buyer 6%. Conversely, if rates fall to 4%, your bond’s price rises to ~$1,040 to yield the buyer 4%. In both cases, at maturity, you receive the full $1,000 par, so longer-term holders are made whole.

Par and yield calculations

The yield to maturity is calculated from the par value. If you pay $950 for a bond with $1,000 par and a 5% coupon, your yield includes not just the $50 annual coupon but also the $50 capital gain you’ll realize at maturity. The exact yield depends on years to maturity, but it’s higher than 5% because you’re buying at a discount.

Similarly, duration and convexity—measures of how much a bond’s price moves with interest-rate changes—are calculated using par value as the reference.

Recovery at default

Par value is the amount the company commits to repay. If the company defaults (goes bankrupt), par is the “recovery value” from which any loss is measured. A bond trading at $400 with $1,000 par is worth much less than par because investors expect to recover only a fraction of the principal in bankruptcy. This is why junk bonds often trade well below par—credit risk is priced in.

Why par matters for comparison

Par value is the standard denominator for comparing bond yields and prices. When traders quote a bond at “105” (105% of par), they mean the price is $1,050 for a $1,000 bond. This standardization allows traders to compare bonds of different maturities and coupons on equal footing.

Callable and putable bonds

For callable bonds, the company can redeem at par (or a slight premium) on or after a specified date. This limits your upside if rates fall and your bond appreciates. For putable bonds, you can force the company to buy back the bond at par under certain conditions, protecting you against price decline.
