Definition of Bond Discount

A bond discount occurs when a bond is issued or purchased for less than its face or redemption value. A bond may trade below par when its coupon rate is lower than prevailing market rates, although changes in credit risk and other market conditions can also cause a discount.

For example, if a bond with a $1,000 face value and a 3% annual coupon trades for $950 when comparable bonds offer higher yields, the bond is trading at a $50 discount to face value.

It is important to distinguish between an original issue discount (OID) and a market discount because they can receive different U.S. federal tax treatment.

Purpose of Bond Discounts in U.S. Financial Markets

Bond discounts can arise for several reasons:

1. Aligns Yield with Market Rates – A lower price can increase a bond's yield when its coupon is below current market rates.
2. Attracts Investors – Issuing a bond below its redemption value can help establish an appropriate market yield.
3. Reflects Interest Rate Changes – Existing bonds may fall below par when market interest rates rise.
4. Affects Accounting and Tax Treatment – Discounts can affect interest expense, interest income, carrying amounts, and federal tax reporting.
5. May Reflect Credit Risk – A significant secondary-market discount can sometimes indicate increased concern about an issuer's ability to repay.

Accounting for Bond Discounts in the U.S.

For Issuers

When debt is issued at a discount, the discount generally reduces the initial carrying amount of the debt relative to the amount payable at maturity. The discount is subsequently recognized as additional interest expense over the debt's term.

Simplified Example Journal Entry at Issuance:

Debt issuance discounts and subsequent interest expense must be presented in accordance with applicable U.S. GAAP requirements.

For Investors

An investor generally initially records a purchased bond at its acquisition price. Subsequent accounting depends on the debt security's classification and applicable U.S. GAAP requirements.

For federal income tax purposes, investors must also distinguish between original issue discount and market discount.

Bond Discount vs. Bond Premium

Advantages and Disadvantages of Bonds Purchased at a Discount

Advantages for Investors

• Potentially Higher Yield – Buying below par can increase yield relative to the stated coupon rate.
• Potential Value at Maturity – Subject to the bond's terms and the issuer's ability to pay, redemption may occur at an amount above the purchase price.
• Opportunities in Changing Rate Environments – Rising market rates can cause existing lower-coupon bonds to trade below par.

Disadvantages for Investors

• Lower Coupon Income – Some discounted bonds provide relatively low periodic coupon payments.
• Tax Complexity – OID and market discount are subject to specific federal tax rules.
• Credit Risk – A deep discount may sometimes indicate deterioration in the issuer's creditworthiness.
• Interest Rate Risk – Bond prices can decline further if market interest rates continue to rise.

Related Terms

• Bond Premium – Occurs when a bond is purchased above the relevant face or redemption amount.
• Par Value – The stated face amount of a bond.
• Original Issue Discount (OID) – Generally, the excess of a debt instrument's stated redemption price at maturity over its issue price.
• Market Discount – A discount that generally arises when a bond's value decreases after issuance, and it is subsequently purchased below the applicable adjusted amount.
• Yield to Maturity (YTM) – A yield measure based on holding a bond to maturity and receiving its scheduled payments, subject to specified assumptions.

Interesting Fact

A zero-coupon bond can generate taxable income even though the investor receives no regular cash interest payments. For many taxable OID instruments, OID is generally included in income as it accrues over the bond's term.

Statistic

According to SIFMA, the U.S. corporate bond market had approximately $12.1 trillion in securities outstanding as of Q2 2026, while corporate bond issuance reached approximately $1.90 trillion through August 2026.

Frequently Asked Questions (FAQ)

1. Why are some bonds sold at a discount?

A bond may trade below par because market interest rates have risen, its coupon is below prevailing rates, its credit risk has increased, or other market conditions have changed. Some bonds are also originally issued at a discount.

2. How is a bond discount treated in accounting?

For issuers, an issuance discount generally reduces the initial carrying amount of the debt and is recognized as additional interest expense over the debt's term using the applicable accounting method.

3. Are discounted bonds riskier?

Not necessarily. A discount can result from changes in market interest rates rather than deterioration in credit quality. However, a large discount may sometimes reflect increased credit or default risk.

4. How are bond discounts taxed in the U.S.?

Tax treatment depends on the type of discount. Original issue discount is generally treated as interest and included in income as it accrues, subject to applicable exceptions. Market discount has separate rules and may generally be recognized as ordinary interest income upon disposition or redemption unless the investor elects to include it currently.

5. What happens at maturity with a discounted bond?

If the issuer fulfills its obligations, the investor generally receives the bond's stated redemption amount at maturity. The difference between the purchase price and redemption amount is not automatically a capital gain because OID and market discount rules may require treating some or all of the discount as interest or ordinary income.
