📌 Chapter 3.3 — Types of Bonds

Imagine you are reviewing the balance sheet of an infrastructure firm that has recently issued deep-discount bonds to fund a long-gestation project. You note that the purchase price is significantly below the face value, and there are no interim coupon payments. While a retail investor might focus solely on the ‘absolute return’—the difference between the purchase price and the redemption value—your role as an analyst requires a more rigorous metric: the Yield-to-Maturity (YTM).

Relying on simple percentage gains ignores the critical factor of time, which is the primary variable that differentiates high-quality research from speculative observation.

YTM represents the internal rate of return (IRR) of a bond if held until maturity, assuming all cash flows are reinvested at the same rate. In the Indian debt market, where various instruments like Zero-Coupon Bonds (ZCBs) are prevalent, YTM serves as the standard yardstick to compare the attractiveness of these debt instruments against traditional interest-bearing corporate bonds or bank deposits. By annualizing the total return, you normalize the gain over the holding period, allowing for a fair “apples-to-apples” comparison across bonds with varying maturities and entry prices.

To see this in practice, consider two bonds: a five-year ZCB bought at Rs. 75 and a ten-year ZCB bought at Rs. 60, both maturing at Rs. 100. Calculating the absolute return makes the ten-year bond appear more attractive due to the larger capital appreciation. However, when you calculate the YTM, you will likely find that the five-year bond offers a superior annualized return, accounting for the shorter duration of capital commitment.

This distinction is vital when building a valuation model, as it forces you to reconcile the firm’s cost of debt with the opportunity cost of capital for your clients.

For an analyst, YTM is not merely a static figure to be quoted; it is a dynamic input that reflects market sentiment regarding interest rate cycles and credit risk. When you advise an institutional client, you must consider whether the YTM adequately compensates for the underlying credit risk of the issuer, especially in the context of India’s evolving corporate bond market.

If the YTM of a bond is significantly higher than the sovereign yield for a similar tenure, your research must investigate whether this ‘yield spread’ is justified by the firm’s fundamentals or if it masks an impending liquidity crunch or credit rating downgrade.1

Nuance

⚠️ Nuance
The most common pitfall for candidates is confusing the ‘Current Yield’ with the ‘Yield-to-Maturity.’ Current yield is a simplistic snapshot that divides the annual coupon by the current market price, completely ignoring the capital gain or loss that occurs at maturity. An analyst who relies on current yield for a zero-coupon bond would mistakenly calculate a return of zero, failing to account for the essential mechanism of price accretion that defines the bond’s true economic performance.

Practice Question 1

An investor buys a zero-coupon bond with a face value of Rs. 1,000 for Rs. 700. The bond matures in exactly 3 years. What is the fundamental nature of the return the investor receives upon maturity?

Practice Question 2

Why is the Yield-to-Maturity (YTM) considered a more robust metric for institutional research than simple percentage return on investment?

  1. The YTM calculation assumes the bond is held until maturity and that all coupon payments are reinvested at the same yield, an assumption known as the ‘reinvestment risk’ which often complicates real-world returns. ↩︎
