Corporate Bonds in India

What They Are, How They Work, and Whether the Extra Yield Is Worth the Risk

Corporate Bonds are debt instruments issued by private companies, public sector undertakings (PSUs), and financial institutions to raise money from investors. In exchange, the issuer pays a fixed coupon (interest) at regular intervals and returns the principal at maturity. Unlike government bonds, corporate bonds carry credit risk the possibility that the issuer may default but compensate with higher yields. They are listed on NSE and BSE, regulated by SEBI, and mandatorily rated by SEBI-recognised credit rating agencies.

The Number That Changes Everything: The Spread

In 2018, IL&FS Infrastructure Leasing & Financial Services was rated AAA. Not just investment grade. The top. The highest rating India's most respected agencies could award. Pension funds held its bonds. Mutual funds held its bonds. Retail investors, told they were buying the safest corporate paper in the market, held its bonds.

Then the company collapsed. Overnight, ₹91,000 crore in debt became the centre of India's largest post-liberalisation financial crisis. Bondholders who thought they owned safety discovered they owned a claim in an insolvency process that would drag on for years. Recovery rates varied from near-zero to partial but the AAA label meant nothing by the time the process concluded.

The lesson wasn't that corporate bonds are dangerous. It was that the extra yield they offer over government bonds that gap between what the government pays you and what a company pays you is not free money. It is compensation for a risk that is real, even when it is invisible.

That gap has a name: the credit spread. Understanding what it means, what drives it, and how to evaluate whether it adequately compensates you for the specific risk you're taking that is the complete science of corporate bond investing.

Done well, corporate bonds are one of the most efficient fixed-income instruments available to Indian investors: predictable income, higher yields than FDs and G-Secs, SEBI regulation, and exchange-listed liquidity. Done carelessly chasing the highest coupon without examining why it's so high they are how sophisticated-sounding investments become painful surprises.

This is the complete picture.

Where Corporate Bonds Sit in the Risk-Return Landscape

Before the detail, a quick orientation. Corporate bonds don't exist in isolation; they sit at a specific point in the fixed-income spectrum between risk-free government bonds and equity.

Reading this table: the yield ladder is real. Every step up in yield reflects a genuine step up in risk. The goal is not to maximise yield it is to find the point on this ladder where the yield premium adequately compensates for the credit risk being assumed.

What Are Corporate Bonds?

A corporate bond is a debt instrument through which a company borrows money from the public or institutional investors. The issuer promises to pay a fixed coupon rate at regular intervals typically annually or semi-annually and return the full face value (principal) on the maturity date.

In India, corporate bonds issued publicly to retail investors are formally called Non-Convertible Debentures (NCDs). The NCD label means they cannot be converted into equity shares; they remain pure debt. Privately placed bonds (issued to institutional investors) are called debentures or bonds depending on the structure.

All publicly issued corporate bonds in India must be:

• Rated by at least one SEBI-recognised credit rating agency (CRISIL, ICRA, CARE, or India Ratings)
• Listed on a recognised stock exchange within 15 days of allotment
• Clearly designated as secured (backed by specific assets) or unsecured (no asset backing) in the offer document

Corporate Bonds at a Glance

Did You Know? India's corporate bond market was worth approximately ₹43 lakh crore in outstanding issuances as of 2024 one of the largest in Asia. Yet retail participation remains less than 5%. The vast majority is held by banks, insurance companies, mutual funds, and provident funds.

Types of Corporate Bonds in India

PSU Bonds: The Conservative Starting Point

PSU bonds sit between G-Secs and fully private corporate bonds on the risk spectrum. Issuers like NTPC, NHAI, REC, Power Finance Corporation, and Indian Railway Finance Corporation carry the implicit backing of the government though they are not sovereign obligations. [LINK: Government Bonds]

PSU bonds typically yield 50–150 basis points more than comparable G-Secs. Older issues from NHAI and REC carry tax-free coupons though new tax-free issuances have been absent since 2016. On the secondary market, the pre-tax equivalent yield for investors in the 30% bracket is considerably higher than the stated coupon.

Secured vs Unsecured NCDs: The Distinction That Matters Most

Secured NCDs are backed by a charge over specific company assets, plant, machinery, receivables, or property. If the issuer defaults, secured bondholders have the first legal claim on those assets during insolvency proceedings.

Unsecured NCDs carry no such charge. Unsecured bondholders stand behind secured creditors in the recovery queue. The higher yield on unsecured bonds reflects this subordination not just business risk, but structural risk within the capital stack.

This distinction is frequently glossed over in marketing materials. Always read the offer document to confirm whether the bond you're buying is secured, and specifically what assets are charged.

AT1 Bonds: The Instrument That Looks Like a Bond But Isn't

Additional Tier 1 (AT1) bonds perpetual bonds are issued by banks and carry features that make them fundamentally different from standard corporate bonds:

• No maturity date the bank can theoretically never repay the principal
• Coupon can be skipped without constituting a default
• Can be written down to zero as Yes Bank AT1 holders discovered in 2020, regulators can write down the entire bond value to support a failing bank

AT1 bonds are loss-absorbing instruments designed to protect depositors in a banking crisis. For retail investors without a deep understanding of banking regulation and capital adequacy frameworks, they are categorically unsuitable regardless of the coupon offered.

How Corporate Bonds Work: The Core Mechanics

Yield-to-Maturity: The Number That Actually Matters

A bond's coupon rate is what the issuer promises to pay annually on the face value. The number you actually care about is the yield-to-maturity (YTM) , the total annualised return you earn if you buy the bond at its current market price and hold to maturity.

If a bond has a face value of ₹1,000, a coupon of 9%, and is trading at ₹950 in the secondary market, the YTM is higher than 9% because you're buying at a discount. If it's trading at ₹1,050, the YTM is lower than 9%.

Always evaluate bonds on YTM, not coupon rate. The coupon is fixed at issuance. The YTM reflects today's reality.

The Credit Spread: What Extra Yield Actually Represents

The credit spread is the difference in yield between a corporate bond and a government bond [LINK: Government Bonds] of the same maturity. It is the market's real-time assessment of the issuer's risk.

A AAA-rated corporate bond might yield 7.8% when the 10-year G-Sec yields 7.2% a spread of 60 basis points. A BBB-rated bond from the same sector might yield 10.0% a spread of 280 basis points. The spread reflects:

• Credit risk: The probability that the issuer will default
• Liquidity risk: How easily you can sell the bond before maturity
• Tenor risk: The uncertainty of holding for a longer period
• Sector risk: Industry-specific vulnerabilities (infrastructure, NBFC, real estate)

When a bond's spread is unusually wide, a company offering 300–400 bps above G-Secs on a supposedly investment-grade bond the market is telling you something. Not necessarily that the bond will default, but that the risk is higher than the rating label suggests. Spreads tell a story that ratings sometimes don't.

Bond Prices and Interest Rates

Corporate bonds share the same fundamental price mechanic as G-Secs: when interest rates rise, bond prices fall; when rates fall, bond prices rise. [LINK: Government Bonds]

Corporate bonds carry an additional layer: credit spread widening. If the market becomes concerned about an issuer even without an actual default the spread widens and bond prices fall. You can face a capital loss not because rates changed, but because sentiment about that company changed. This dual exposure makes corporate bond prices more volatile than equivalent G-Secs in the same rate environment.

Key Takeaway: The yield premium of a corporate bond over a G-Sec of the same maturity the credit spread is not a gift. It is the market's price for the credit risk you are assuming. A wider spread means the market sees more risk. Before investing, always ask: does this spread adequately compensate me for this specific issuer's risk?

Understanding Credit Ratings

Every publicly issued corporate bond in India must carry a rating from a SEBI-recognised agency. The rating is an opinion on the issuer's ability to pay coupons on time and return principal at maturity.

The four SEBI-recognised agencies: CRISIL (S&P affiliate), ICRA (Moody's affiliate), CARE Ratings, and India Ratings & Research (Fitch affiliate).

What Ratings Can and Cannot Tell You

Ratings are useful for comparing relative risk. They are not infallible. IL&FS was rated AAA until weeks before its collapse. The lesson: rating agencies are reactive, not predictive; they typically downgrade after problems become visible, not before.

Use the rating as a starting point, then go further:

• Cash flow analysis: Is the company generating enough cash to service its debt? Profitability ratios can be managed; cash flow is harder to fabricate.
• Interest coverage ratio: EBIT divided by interest expense. Below 1.5x is a warning sign regardless of the rating.
• Promoter and governance track record: Related-party transactions, pledged promoter shares, and regulatory actions deserve extra scrutiny.
• Sector-specific risk: NBFCs, real estate developers, and infrastructure companies are structurally more vulnerable to liquidity shocks than diversified industrials.
• Rating outlook and trend: A bond rated AA on CreditWatch Negative tells a different story than one rated AA with a stable outlook. Multiple downgrades in rapid succession are a severe warning signal.

The Defaults That Redrew India's Corporate Bond Map

Between 2018 and 2021, a cascade of corporate bond defaults changed how sophisticated Indian investors think about fixed income. Each event added a specific lesson.

The common thread: investors stopped doing independent due diligence and outsourced their judgment to rating labels and brand names. A rating is a starting point. It is not a substitute for thinking.

How to Invest in Corporate Bonds: Step by Step

Pre-Buy Checklist: Before You Commit to Any Corporate Bond

Run through this before placing any order:

• Credit rating What is the current rating, and from which agency? Is there a second rating? Do they agree?
• Rating outlook Stable, Positive, or Negative Watch? Multiple recent downgrades?
• Yield-to-Maturity (YTM) What is the actual annualised return at the current market price?
• Maturity date Does this match your actual investment horizon? Can you hold until maturity?
• Secured or unsecured Is the bond backed by specific assets? What exactly is charged?
• Interest payment frequency Annual or semi-annual? Does this match your income needs?
• Liquidity What is the daily traded volume of this bond on BSE/NSE? Is there a realistic exit if you need it?
• Credit spread How does the YTM compare to G-Secs of the same maturity? Is the premium justified by the risk?
• Issuer financials What is the interest coverage ratio? Is cash flow generation adequate to service this debt?
• Sector context Is the industry the issuer operates in under stress? Regulatory headwinds? Liquidity issues sector-wide?

Where to Find Corporate Bonds

Primary Market (New Issues): Companies periodically issue NCDs for public subscription through SEBI-filed offer documents. These are open for 3–15 days, distributed through brokers and investment platforms, with a minimum investment of typically ₹10,000. Listed on BSE/NSE within 6 business days of allotment.

Secondary Market: Listed corporate bonds trade on NSE and BSE's debt platforms. Use your existing demat account, search by ISIN code, check the current YTM, and place a buy order. Note: retail secondary market liquidity for corporate bonds is significantly thinner than for G-Secs bid-ask spreads can be wide for lesser-known issuers.

Bond Mutual Funds and ETFs: Invest in a diversified portfolio of corporate bonds via a professional fund manager. Daily liquidity, no minimum lot constraints, and built-in diversification. Trade-off: expense ratios (0.2–0.5% for direct plans) and you inherit the fund manager's credit calls.

Should You Hold Corporate Bonds Directly or Through a Mutual Fund?

This is the question most beginners don't know to ask. The answer depends entirely on what you're trying to accomplish.

The tax asymmetry is the critical differentiator post-Budget 2023. Debt mutual funds (including corporate bond funds) lost their LTCG and indexation benefit in March 2023 gains are now taxed at slab rate regardless of holding period. Direct bond holdings in listed securities retain the 12.5% LTCG treatment after 24 months (per Finance Act 2024). For investors in the 30% bracket holding bonds for 2+ years, this creates a meaningful post-tax advantage for the direct route.

The due diligence requirement is the critical differentiator in the other direction. A corporate bond fund with a seasoned credit team has resources to assess issuers that individual retail investors simply cannot replicate. For most retail investors entering corporate bonds for the first time, starting with a well-regarded corporate bond fund is the more prudent entry point and moving to direct holdings selectively as familiarity with credit analysis grows.

Returns and Taxation (Budget 2024 Rules)

What Returns Can You Expect?

Indicative yield ranges for Indian corporate bonds as of FY2025-26:

• AAA-rated corporates (5yr): ~8.0–8.8%
• AA-rated (5yr): ~8.8–9.8%
• PSU bonds (AAA, 10yr): ~7.5–8.2%
• A-rated NCDs (3-5yr): ~9.5–11.5%
• Tax-free PSU bonds (secondary market): Effective pre-tax yield ~9–11% for investors in the 30% bracket

Compare this to the 10-year G-Sec at ~7.0–7.3%. A AAA corporate bond offers roughly 80–150 bps more. Each notch down in rating adds another 100–200 bps. The yield premium is real. So is the risk differential.

How Corporate Bond Income Is Taxed

The strategic implication for 30% bracket investors: A coupon of 8.5% nets approximately 5.95% post-tax. A bond trading below face value that delivers returns primarily through capital appreciation benefits from the 12.5% LTCG rate if held more than 24 months netting approximately 7.4% post-tax on the same gross yield. This is the rationale for discount bonds in high-bracket fixed-income portfolios.

Corporate Bonds vs Other Fixed-Income Options

🔎 Exploring the Bond Landscape

Fixed-income investing in India has historically been fragmented navigating multiple platforms, offer documents, credit reports, and brokerage accounts to build what should be a coherent portfolio. Government bonds anchor it with zero default risk. PSU bonds add modest yield. AAA and AA corporate bonds step up the yield further. Each instrument serves a different purpose at a different point in the risk spectrum. Platforms like Finzace provide a single discovery surface to compare bonds, FDs, and other fixed-income instruments available through regulated partner institutions so investors can see the full landscape in one place. KYC, execution, and settlement are handled directly by the respective SEBI-registered or RBI-regulated entities.

Advantages and Limitations

Advantages

• Fixed, predictable interest payments
• Wide range of maturities and issuers to choose from
• Listed on NSE/BSE tradable before maturity
• SEBI-regulated mandatory ratings and disclosures
• Portfolio diversification beyond equities [LINK: Fixed Income Portfolio]

Limitations

• Credit risk the issuer can default (unlike G-Secs)
• Interest rate risk prices fall when market rates rise
• Retail secondary market liquidity is thin
• Interest income taxable at slab rates
• Due diligence is the investor's responsibility in the direct route
• High minimum investment in many primary issues

Who Should Invest in Corporate Bonds?

Corporate Bonds may suit you if you are...

• ✅ An investor in the 30% tax bracket seeking better post-tax returns than FDs
• ✅ A conservative investor stepping up from G-Secs for extra yield [LINK: Government Bonds]
• ✅ Building a bond ladder with specific maturity targets [LINK: Bond Laddering]
• ✅ Someone with a 3–10 year horizon and no need for early liquidity
• ✅ An investor with deposits significantly above the DICGC ₹5 lakh limit
• ✅ A retiree or near-retiree wanting stable coupon income

Reconsider if you are...

• ❌ Likely to need emergency access to funds the secondary market is illiquid
• ❌ Unwilling to do issuer-level due diligence the rating alone is not enough
• ❌ Investing for less than 2–3 years FDs or T-Bills are more appropriate
• ❌ A first-time fixed-income investor with no understanding of credit risk

Red Flags: When to Walk Away

These patterns appeared repeatedly in India's worst corporate bond defaults. Any one of them warrants serious pause; multiple together is a clear exit signal.

Yield significantly above peers for no clear reason. If a bond yields 300–400 bps more than similarly rated peers, the market either knows something the rating doesn't, or the issuer is structurally desperate for cash. Neither is a good reason to invest.

Promoter shares heavily pledged. Heavy promoter pledging is a governance red flag that preceded multiple Indian defaults. It signals the promoter is extracting capital from the business using the company's own equity as collateral which accelerates loss of control precisely when the company is under stress.

Persistent refinancing of existing debt. Companies that are perpetually rolling over short-term borrowings to fund long-term assets are running a structural liquidity mismatch. IL&FS did exactly this for years before its collapse.

Multiple rating downgrades in rapid succession. A single downgrade can reflect a specific event. Three downgrades in 12 months from AAA to AA to A indicates fundamental deterioration, not isolated setbacks.

Complex group structures and related-party transactions. If you cannot clearly understand where the money you're lending goes and how it comes back, the bond is too complex to invest in.

Sector-level stress the rating hasn't yet reflected. If an entire sector is under documented pressure, regulatory changes, demand collapse, liquidity crunch bonds in that sector carry more risk than their current rating suggests, regardless of individual issuer history.
