Coupon Payment

A coupon payment is the interest check you get for holding a bond. It’s called a “coupon” because old bonds were issued with tear-off coupons that you’d bring to a bank to collect interest—a tedious system that modern electronic settlement has replaced, but the name stuck. The coupon rate is fixed at issuance, so it doesn’t change with market conditions or inflation.

How coupon payments work

A bond specifies a coupon rate—say, 4.5% per year. If the par value is $1,000, the annual coupon is $45. Most corporate bonds pay this semi-annually, so you’d receive $22.50 every six months. The payment is contractually required; it’s the company’s obligation to you as a bondholder, written into the bond indenture.

On each payment date, the company’s transfer agent (or paying agent) distributes the coupon to all registered bondholders. The payment is the same regardless of what price you paid for the bond. If you bought the bond at a discount ($900) or a premium ($1,100), your coupon is still $45 per year—the rate doesn’t adjust.

Coupon vs. yield

This is the source of confusion for many investors. The coupon (4.5%) is fixed when the bond is issued. The yield—the effective return you earn if you hold the bond to maturity—depends on what price you pay for it.

If you buy a bond with a 4.5% coupon at par ($1,000), your yield is roughly 4.5%. If you buy the same bond at a discount ($900) because interest rates rose, your yield is higher—roughly 5.3%—because you’ll also realize a capital gain when you get back $1,000 at maturity. If you buy at a premium ($1,100), your yield is lower because you’ll realize a capital loss. The coupon payment stays the same; the yield changes with price.

Coupon dates and accrued interest

Bonds pay interest on specific dates written into the indenture. If you buy a bond between coupon dates, you pay the accrued interest to the previous owner—the fraction of the next coupon you’ve “earned” by holding the bond for part of the coupon period. This is tracked using the accrued interest convention.

Why companies issue fixed coupons

A company typically locks in a coupon rate that reflects its credit rating, the maturity, and prevailing interest rates. A junk-rated company with a long maturity might issue a 7% coupon, while a investment-grade company with short maturity might issue 3.5%.

The company can’t change the coupon once the bond is issued, even if interest rates drop. This is why callable bonds exist—they give the company the option to refinance (buy back the bond and issue new bonds at a lower coupon) if rates fall enough to make it economical.

Coupon defaults and credit events

If a company fails to make a coupon payment on the due date, it’s technically in default, even if it’s otherwise solvent. This triggers the cascade of remedies outlined in the bond indenture: bondholders can demand acceleration (immediate repayment of the full principal) or negotiate a restructuring. For investment-grade companies, a single missed coupon is rare and usually signals severe distress. For high-yield bonds in stress, it’s more common to see companies miss coupons during bankruptcy or Chapter 11 reorganization.
