Corporate Bonds and NCDs in India: Higher Yield, Real Risks
How corporate bonds and NCDs work in India, why they offer higher yields than bank FDs, the credit and liquidity risks involved, and how they are taxed.
When a fixed deposit pays 7% and a company's NCD offers 9.5%, the extra 2.5% looks like easy money. It is not. That gap is the market's price for a specific, measurable risk: the chance that the company does not pay you back. Understanding corporate bonds and NCDs properly means understanding exactly what you are being paid extra to bear.
This is an area where Indian retail investors have historically been under-served and occasionally burnt — several high-profile defaults over the years turned "safe-looking" fixed-income products into painful losses. The instruments are perfectly legitimate and can have a place in a portfolio. But they reward investors who read the fine print and punish those who chase the headline coupon.
What a corporate bond actually is
A corporate bond is a loan you make to a company. In return, the company promises to pay you a fixed rate of interest (the coupon) at regular intervals and to return your principal (the face value) on a fixed date (the maturity). That is the entire mechanism.
An NCD — Non-Convertible Debenture — is simply a kind of corporate bond. "Debenture" is the term for an unsecured or secured debt instrument; "non-convertible" means it will never turn into equity shares — it remains debt and is repaid in cash. Most retail investors in India encounter corporate debt through public NCD issues, which open for subscription for a fixed window like an IPO, and through listed bonds traded on the exchanges.
Some NCDs are secured (backed by specific company assets that bondholders can claim if things go wrong) and some are unsecured (no specific collateral). Secured does not mean risk-free, but it generally improves your position in a default.
Why the yield is higher than a bank FD
A bank fixed deposit is, in effect, lending to a bank — and bank deposits up to ₹5 lakh are covered by deposit insurance. A corporate bond is lending to a company, with no such insurance. The company has to offer a higher rate to attract your money away from the safer alternative.
The size of that extra rate — the credit spread — depends mainly on how risky the company is perceived to be. A blue-chip, AAA-rated issuer might offer only a small premium over a government bond. A lower-rated issuer must offer much more to compensate for the higher chance of default.
So the rule of thumb is uncomfortable but accurate: higher yield means higher risk, almost always. If one NCD pays dramatically more than another of similar maturity, the market is telling you it considers the high-yielder riskier. The extra return is not generosity; it is hazard pay.
Credit ratings: useful, but not gospel
Indian bonds and NCDs are rated by agencies such as CRISIL, ICRA, CARE and India Ratings, using a scale that runs roughly from AAA (highest safety) down through AA, A, BBB (the lowest "investment grade"), then BB and below (increasingly speculative), to D (default).
| Rating band | Broad meaning | Typical use |
|---|---|---|
| AAA | Highest safety, lowest default risk | Core, conservative holdings |
| AA | High safety | Acceptable for most investors |
| A | Adequate safety | Requires more scrutiny |
| BBB | Moderate safety (lowest investment grade) | Higher risk; size carefully |
| BB and below | Speculative / high risk | Generally unsuitable for retail |
| D | In default | Avoid |
Two things matter about ratings. First, a rating is an opinion about the future, not a guarantee. Agencies can and do get it wrong, and some past defaults came from issuers that had carried respectable ratings until shortly before trouble. Second, ratings can change after you buy. A downgrade can hit the bond's market price and signal rising risk even if no default has occurred. Treat the rating as the start of your homework, not the end of it.
A practical discipline: be wary of reaching far down the rating ladder for yield. The jump from AAA to AA costs you a little return for a lot of comfort. The jump from A to BB buys you a lot of headline yield for a meaningful chance of not being repaid.
The liquidity risk nobody mentions
With a bank FD, you can break it early, lose a little interest, and get your money back. Corporate bonds do not work that way. To exit before maturity, you generally have to sell the bond to another buyer on the exchange — and the Indian corporate bond market is far less liquid than the equity market.
For many bonds, especially smaller or lower-rated issues, there may be very few buyers on any given day. That means:
- You might not be able to sell quickly when you want to.
- When you can sell, you may have to accept a discount to get the trade done.
- The price you see quoted may not reflect what you actually receive.
This is why bonds suit money you can genuinely commit until maturity. If there is a real chance you will need the funds early, the illiquidity can cost you more than the extra yield earned. For money you might need at short notice, a liquid emergency reserve in a savings account or sweep FD is the right home — not a corporate bond.
Tax: why the headline coupon overstates your return
Interest from corporate bonds and NCDs is added to your income and taxed at your slab rate, under "Income from Other Sources". This is the part that quietly erodes the apparent advantage over equity or even over some other instruments.
Consider the headline 9.5% NCD again. If you are in the 30% tax bracket, your post-tax return is roughly 9.5% × (1 − 0.30) = 6.65%. Suddenly the gap over a 7% FD (post-tax ~4.9% in the same bracket) is narrower than it looked, and you have taken on credit and liquidity risk for the privilege.
If you sell a listed bond on an exchange before maturity, the profit is treated as a capital gain and taxed according to the holding period under the prevailing rules. Tax treatment of debt instruments has changed in recent years, so verify the current rules — but the core lesson stands: compare bonds on a post-tax yield, not the coupon. A lower-coupon instrument that is tax-efficient can beat a higher-coupon one that is taxed at your full slab.
A worked example: AAA versus high-yield NCD
Suppose you have ₹5,00,000 to invest for five years and you are in the 30% slab. You are weighing a AAA-rated NCD at 8% against a lower-rated NCD at 11%.
| AAA NCD | Lower-rated NCD | |
|---|---|---|
| Coupon | 8% | 11% |
| Annual interest (₹5 lakh) | ₹40,000 | ₹55,000 |
| Post-tax interest (30% slab) | ₹28,000 | ₹38,500 |
| Post-tax yield | 5.6% | 7.7% |
| Default risk | Low | Materially higher |
| Liquidity | Better | Often poorer |
The lower-rated NCD pays roughly ₹10,500 more per year after tax — about 2.1 percentage points of extra yield. The question is whether that 2.1% is worth the materially higher chance that, somewhere in those five years, the issuer runs into trouble and you face a delayed payment, a haircut, or a default that wipes out far more than five years of extra interest.
For most investors, the answer is to stay high on the rating ladder and treat the extra yield from weak issuers as a trap rather than an opportunity. You can model how different yields compound over your holding period in a lumpsum calculator — but always plug in the post-tax yield, not the coupon.
What to check before you subscribe
When a public NCD issue opens, the offer document runs to many pages, but a handful of items tell you most of what you need to know. Reading these takes minutes and separates an informed investor from one who simply chased the coupon.
The credit rating — and who gave it. Note not just the rating but the agency and whether there is any "rating watch" or recent change flagged. A stable AA from a recognised agency is a different proposition from a rating recently placed under review.
Secured or unsecured. A secured NCD is backed by specific company assets that bondholders can claim in a default; an unsecured one is not. Secured does not mean safe, but it improves your standing if things go wrong.
The call option. Some NCDs are callable — the issuer can repay early, often when interest rates fall. That is good for the company and inconvenient for you, because you get your money back precisely when you can only reinvest it at lower rates. Check whether and when the issuer can call the bond.
Coupon frequency and maturity. Confirm whether interest is paid monthly, annually or only at maturity (cumulative), and that the maturity date genuinely matches money you can lock away. Then convert the coupon to a post-tax yield, as discussed above, before comparing.
Where corporate bonds fit in a portfolio
Corporate bonds and NCDs belong in the debt portion of your portfolio, alongside instruments like PPF, EPF and debt funds. Their role is to provide a fixed, contractual income stream that is somewhat higher than government-backed options, in exchange for accepting issuer risk.
For investors who want the higher-yield-debt exposure but are nervous about picking individual issuers, debt mutual funds offer a diversified alternative — a fund holds dozens of bonds, so a single default hurts less. The trade-off is that you give up the certainty of a fixed maturity value. Our guide to debt mutual funds in India covers how these work and where credit-risk funds sit on the spectrum. Stepping back, deciding how much of your money should sit in debt at all is fundamentally an asset allocation question.
Common mistakes
Chasing the highest coupon. The instinct to pick the NCD paying 12% over the one paying 8% is exactly backwards. The 12% is the market shouting that it considers the issuer risky. Yield is a warning label as much as a reward.
Ignoring liquidity until you need the money. Investors buy a bond assuming they can sell anytime, then discover at the worst moment that there are no buyers. Match the bond's maturity to a date you are genuinely comfortable locking money away.
Treating a credit rating as a guarantee. Ratings are informed opinions that can be wrong and can be downgraded. Concentrating a large sum in a single issuer because it is "AA-rated" still leaves you exposed if that single company stumbles.
Comparing coupons instead of post-tax yields. Because bond interest is taxed at your slab, the headline rate overstates your real return — especially in higher brackets. Always run the post-tax number before deciding.
Putting too much in a single name. Even with a good rating, diversification matters. A portfolio of one bond is a bet on one company. Spread across issuers, or use a diversified debt fund.
What to do next
- Define the role: decide what slice of your debt allocation, if any, you want in corporate bonds versus safer government-backed options.
- Set a minimum rating you will accept and stick to it — for most retail investors, staying at AA or above is sensible.
- Match maturities to money you can genuinely lock away, given the limited liquidity of the secondary bond market.
- Convert every coupon to a post-tax yield using your slab rate before comparing instruments or against an FD.
- Diversify across issuers, or use a debt mutual fund if picking individual bonds feels like too much concentration risk.
- Buy only through SEBI-registered platforms or recognised exchanges, and read the offer document for security, seniority and call features.
- Verify the current tax treatment of bond interest and capital gains, and check issuer ratings on the rating agencies' sites, before committing funds — rules and ratings both change over time.
