Many people opt for corporate bonds based on yields alone. They check the highest return available among the different bonds. There are several problems with this approach. The yield is just one of the elements you should consider when making decisions; usually, the higher the yield, the more risks there are associated with the corporate bond. If you want to make a well-informed choice, you must consider all aspects related to the bond itself, rather than relying only on the single element that might mislead you. This guide will help you make sense of everything that matters in the world of corporate bonds.
Why Comparing Bonds Requires More Than Just Yield
While yield indicates how much an investor will be earning from his investment, yield says nothing about the security of this return. If two bonds offer the same yield of 9%, their degree of risk may be very different because of factors such as the creditworthiness of the issuing institution, the bond’s priority in the pecking order, and its ability to be resold before maturity. Credit rating firms analyse a company’s past performance, debt coverage ratios, and history of defaults before issuing a bond grade, which influences the coupon rate, price, and degree of risk associated with the bond. In other words, yield is a product of risk, not a measure of it.
Key Factors to Compare When Evaluating Corporate Bonds
Before choosing between two corporate bonds, it helps to run through a consistent checklist. The sections below cover the factors that matter most for Indian corporate bonds today.
Credit Rating and Credit Quality
Credit rating is the most crucial place to start. Bond ratings in India start from AAA, which denotes the highest creditworthiness, and go down to D, which denotes default, with ratings given by rating agencies like CRISIL, CARE, and ICRA. Bonds having ratings from AAA to BBB- are categorised under the investment grade category and are perceived as low-risk, while bonds with ratings BB+ and below are non-investment-grade and high-yield.
It must be noted that there is indeed a difference in ratings. Data provided by CRISIL reveals that one-year default rates of AAA-rated securities are around 0%, 0.2% for AA, 1.5% for A, 5% for BBB, and more than 20% for ratings BB and below. In other words, this represents an increase in the level of risk associated with a marginal change in yield, hence the importance of the comparison of ratings before comparisons of returns.
It is also worth noting that nearly 85 to 90% of bond issuances in India are rated AAA or AA, according to SEBI Chairman Tuhin Kanta Pandey, meaning lower-rated bonds are less common and often demand closer scrutiny.
Yield to Maturity (YTM) vs Coupon Rate
Coupon rate refers to the fixed interest paid on the face value of the bond. Yield to maturity, on the other hand, takes into account the return earned when holding the bond till its maturity by considering the price of the bond, time left and the reinvestment of coupons.
For example, suppose a bond has a face value of ₹1,000 and a coupon rate of 8%, meaning it pays ₹80 in interest each year. If the bond is purchased in the secondary market for ₹950, the YTM is likely to be higher than 8% because the investor receives the annual coupon payments and also stands to receive ₹1,000 at maturity, resulting in a capital gain of ₹50. Conversely, if the same bond is purchased for ₹1,050, the YTM is likely to be lower than 8% because the investor pays more than the face value and incurs a capital loss of ₹50 when the bond matures.
When comparing bonds available in the secondary market, investors generally compare their Yield to Maturity (YTM) rather than the coupon rate, as YTM provides a more comprehensive measure of the bond's expected return if held until maturity.
Maturity and Duration
The maturity date is when the borrower pays back the face value of the security, while the duration is used as an indicator of the sensitivity of the bond prices to interest rate fluctuations. In general, bonds having higher maturity dates will have higher durations, depending on the coupon rate, yield level and cash-flow timing.
Liquidity
Liquidity is the ease of buying and selling the bond without causing any movement in its prices. Corporate bonds in India tend to be less liquid than government bonds. On an average, the daily volume corporate bonds being around ₹1.4 trillion per month, compared to equity market trading volumes of a similar size per day. Prior to comparing two bonds, check out their trading volumes on exchanges.
Security Cover
Security cover indicates whether a bond is backed by specific collateral (secured) or relies purely on the issuer's promise to pay (unsecured). Secured bonds typically offer bondholders a claim on identified assets if the issuer defaults, giving an added layer of protection compared to unsecured bonds, which rank behind secured creditors in a liquidation. When comparing two bonds with similar yields, a secured structure with adequate asset cover generally represents lower risk than an unsecured one.
Issuer Financial Strength
Beyond the credit rating itself, it helps to look at the issuer's underlying financial health: debt-to-equity ratio, interest coverage ratio, cash flow stability, and sector concentration. Pandey noted that around 70% of outstanding corporate bonds in India come from financial sector entities, so sector concentration risk is a real consideration, particularly if your overall portfolio is already exposed to financial services or NBFCs. A strong standalone rating combined with weak sector diversification can still leave you exposed to systemic risk.
Tax Implications
Interest income from corporate bonds is taxed as per your income slab, and capital gains rules depend on the holding period and whether the bond is listed. Two bonds with the same pre-tax yield can deliver very different post-tax returns depending on your tax bracket and the bond's listing status. Always calculate the after-tax return before finalising a comparison, especially if you are in a higher tax bracket.
Common Mistakes to Avoid When Comparing Corporate Bonds
- Chasing the highest yield without checking the credit rating behind it
- Ignoring liquidity and assuming you can exit easily before maturity
- Comparing coupon rates instead of Yield to Maturity
- Overlooking sector concentration when the issuer belongs to a crowded space like NBFCs
- Failing to check whether the bond is secured or unsecured
- Not accounting for taxation when comparing net returns
- Assuming a single high rating guarantees safety without reviewing recent rating outlook changes
Choosing the Right Corporate Bond for Your Investment Goals
The right bond depends on your personal risk appetite, investment horizon, and tax situation. A few practical steps can help:
- Define your holding period first, then match the bond maturity to it
- Decide how much credit risk you are willing to accept. Conservative investors typically stay within AAA/AA, while those comfortable with more risk may consider A or BBB for extra yield
- Check the bond's liquidity on exchange platforms before committing, especially for early-exit flexibility
- Compare YTM, not coupon rate, across shortlisted options
- Review whether the bond is secured and what collateral backs it
- Factor in your tax slab to estimate the real, post-tax return
- Diversify across issuers and sectors rather than concentrating in one industry
Conclusion
Comparing corporate bonds well means moving past the yield figure and examining the full risk picture: credit rating, YTM, maturity, liquidity, security cover, issuer strength, and taxation. India's corporate bond market, valued at roughly US$644.9 billion, has been growing at over 12% annually, giving investors a widening set of choices, but also a growing need for careful comparison. A disciplined, multi-factor approach helps you choose bonds that genuinely match your goals rather than ones that simply look good on the surface.
FAQs on Corporate Bonds Beyond Yield
What is the difference between coupon rate and yield?
Coupon rate is the fixed interest paid on the bond's face value, while yield (specifically YTM) reflects your actual return based on the price you paid and time to maturity.
How does a credit rating help compare corporate bonds?
It gives a standardised measure of default risk, letting you gauge how safe one bond is relative to another, backed by historical default data from agencies like CRISIL.
Does a higher-yielding corporate bond always offer better value?
Not necessarily. A higher yield often reflects higher credit risk, lower liquidity, or weaker security, so it must be weighed against these factors, not viewed in isolation.
What financial information should investors review before comparing corporate bonds?
Review the issuer's credit rating, debt levels, interest coverage ratio, sector exposure, and recent rating outlook, along with the bond's security structure.
Where can investors find information to compare corporate bonds?
Rating agency websites (CRISIL, ICRA, CARE), SEBI-regulated online bond platforms, and exchange data from NSE and BSE are reliable sources for ratings, prices, and liquidity data.
