Deferred Interest Bond

A deferred interest bond is a bond that postpones cash interest payments, causing interest to accrue, accrete into the bond’s value, or be paid later under the bond terms. The structure can reduce near-term cash outflow for the issuer but increases the importance of maturity repayment, credit risk, tax timing, and liquidity.

Key Takeaways

• Deferred interest is about payment timing: economic interest may accrue even when no cash coupon is paid currently.
• Zero-coupon bonds are one common deferred-interest structure, but not every deferred-interest bond is a pure zero-coupon bond.
• Investors should review whether unpaid interest compounds, accretes to principal, is paid at maturity, or becomes payable after a deferral period.
• Tax treatment can be complex; in some cases investors may owe tax on accrued income before receiving cash.

How Deferred Interest Works

A traditional coupon bond pays periodic cash interest. A deferred-interest bond shifts some or all interest to later periods. The issuer’s documents may describe original issue discount, accreted value, deferred coupons, step-up periods, or payment terms that change over time.

For a simplified zero-coupon structure:

Where FV is the amount due at maturity, PV is issue price or present value, r is the periodic yield assumption, and n is the number of periods. Actual tax, accounting, and pricing treatment can be more complex.

Deferred Interest vs. Nearby Structures

Practical Example

A company issues a bond that pays no cash coupon for the first three years, then begins paying cash interest. Investors may accept the structure if the issuer needs time to stabilize cash flow. The risk is that the deferred interest increases the issuer’s later burden, and the bond may be harder to sell if credit quality weakens before cash payments begin.

What To Verify

• Whether interest is deferred, compounded, capitalized, accreted, or paid in kind.
• When cash payments begin and whether missed or deferred amounts must be paid later.
• Maturity date, call features, covenant protections, and events of default.
• Tax treatment of accrued or imputed interest in the relevant jurisdiction.
• Market liquidity and pricing source.

Common Mistakes

• Assuming no cash coupon means no income accrues.
• Treating deferred-interest bonds as simple savings products.
• Ignoring tax timing on original issue discount or accrued income.
• Comparing stated yield without considering credit risk and liquidity.
• Overlooking that deferred cash payments may signal issuer liquidity constraints.
