Par Value

What Is Par Value?

Par value is the face amount printed on a bond, representing the principal that the issuer promises to repay when the bond matures. For most U.S. corporate and government bonds, par value is $1,000 per bond. Municipal bonds may have different denominations, and Treasury securities can be purchased in increments as small as $100.

Par value serves two key functions: it is the amount returned to bondholders at maturity, and it is the base for calculating coupon payments. A 4% coupon on a $1,000 par value bond means $40 in annual interest.

Why It Matters for Markets

The relationship between a bond's market price and its par value tells traders whether the bond is trading at a premium, par, or discount. This relationship directly reflects how the bond's coupon rate compares to current market yields.

When a bond's coupon rate equals the market yield for similar bonds, it trades at par ($1,000). When the coupon exceeds market yields, the bond trades at a premium (above $1,000) because investors will pay extra for the above-market income. When the coupon is below market yields, the bond trades at a discount (below $1,000) because the below-market income must be supplemented by capital appreciation.

Bond prices are often quoted as a percentage of par. A price of "98" means 98% of par value, or $980 per $1,000 bond. A price of "103" means $1,030. This convention makes it easy to compare bonds with different par values and quickly assess premium/discount status.

Par Value and Price Convergence

One of the most important dynamics in bond investing is that prices converge toward par as maturity approaches. A bond trading at $900 with five years to maturity will gradually appreciate toward $1,000 as each year passes, assuming no default. This "pull to par" effect means that the price component of return becomes increasingly predictable as maturity nears.

This convergence is why short-term bonds have lower price volatility than long-term bonds. A 30-year bond trading at a discount has decades for interest rate changes to affect its price, while a 1-year bond will be at par within 12 months regardless of rate movements. Understanding this dynamic is essential for managing duration risk in a bond portfolio.
