Corporate bonds allow companies to borrow directly from investors. In return, investors typically receive interest and principal repayment according to the bond terms.
They can support income and diversification, but they are not fixed deposits: credit risk, liquidity risk, and interest-rate risk still matter.

What is a corporate bond?
A corporate bond is a debt security a company issues. When you buy one, you are lending money to the issuer rather than becoming an owner of the business.
The issuer promises to pay interest according to the coupon terms and repay principal at maturity, provided it remains able and willing to meet its obligations.
Bonds can be secured or unsecured, listed or unlisted, fixed-rate or floating-rate, senior or subordinated. These differences affect risk.
A secured bond may have specified collateral, but collateral does not eliminate default risk or guarantee effortless recovery.
Coupon rate, market price and YTM: the three numbers investors confuse
The coupon rate is the interest rate stated on the bond’s face value. Market price is what you actually pay in the secondary market.
Yield to Maturity, or YTM, is the annualised return implied by the current price if you hold the bond until maturity and receive the promised cash flows, reinvesting them as assumed by the calculation.
If a ₹1,000 face-value bond pays a 9% coupon, the annual coupon is ₹90. If the bond trades below ₹1,000, its YTM may be above 9%; if it trades above ₹1,000, YTM may be below 9%.
YTM is therefore more useful than coupon for comparing bonds with different market prices, but it is not a guarantee of realised return.

Credit ratings: useful, but not a guarantee
Credit-rating agencies assess the issuer’s ability to service debt. Higher ratings generally indicate lower assessed credit risk, while lower ratings imply greater risk and usually demand higher yields.
Investors should nevertheless treat a rating as an opinion at a point in time, not insurance against default.
Read beyond the rating symbol. Look at the rating rationale, debt levels, interest coverage, cash flow, refinancing needs, promoter support, industry cycle and whether the rating has recently been downgraded or placed on watch.
A very high yield from a weak issuer is not “extra interest for free”; it is compensation for risk.
Where can retail investors buy corporate bonds?
Investors can access listed debt through exchange-linked channels, brokers and SEBI-regulated Online Bond Platform Providers (OBPPs). SEBI maintains links to registered OBPP lists through the exchanges.
In 2026, SEBI also modified the OBPP framework, making it important to use registered platforms rather than unregulated websites promising unusually high fixed returns.
Another route is a debt mutual fund or target-maturity fund, where a professional manager holds a basket of securities. This sacrifices the certainty of owning a specific bond to maturity but improves diversification.
The appropriate route depends on ticket size, ability to analyse issuers and desired liquidity.
How to buy a bond step by step
First, complete KYC and maintain a demat account where required. Second, shortlist bonds by issuer quality, maturity and yield rather than yield alone.
Third, check the ISIN, credit rating, coupon type, payment frequency, maturity date, security cover, call/put features and whether the security is listed.
Before placing the order, compare the clean/dirty price conventions shown by the platform, accrued interest, transaction charges and liquidity. After purchase, track corporate announcements and rating actions.
A bond is not a “buy and forget” product when the issuer’s credit quality is changing.
Major risks in corporate bonds
Credit/default risk is the risk that interest or principal is delayed or not paid. Interest-rate risk is the risk that market prices fall when prevailing yields rise; this is more pronounced in longer-duration bonds.
Liquidity risk appears when you want to sell but there are few buyers. Reinvestment risk matters when coupons received cannot be reinvested at a similar yield.
Callable bonds add another wrinkle: if rates fall, an issuer may exercise a call according to the terms, forcing the investor to reinvest earlier. Concentration is another common mistake.
Putting a large part of a portfolio into one high-yield issuer can turn an income allocation into a binary credit bet.
Corporate bond taxation in India
Interest from bonds is generally taxable according to the investor’s applicable income-tax treatment. Capital gains on sale or redemption depend on the nature of the security, holding period and current tax law.
Tax rules have changed in recent years, so investors should verify the treatment applicable to the specific bond and transaction year rather than rely on an old “listed bond = long-term after X months” rule.
When comparing a 9% bond with a bank deposit or debt fund, compare post-tax return, not just headline yield. A high-bracket investor may retain materially less than the coupon rate after tax.
How to build a safer bond allocation
Diversify across issuers and maturities. Many investors use a ladder: instead of buying one five-year bond, they spread maturities across one, two, three, four and five years. This can reduce reinvestment timing risk and create periodic liquidity.
For core capital, prioritise issuer quality and structure before chasing yield. Use lower-rated or subordinated debt only if you understand how it behaves in stress.
If individual bond analysis is impractical, a diversified debt fund, target-maturity fund or high-quality bond portfolio may be operationally simpler.
Bond Metrics
| Metric | Meaning | Investor use |
| Coupon | Interest based on face value | Shows contractual cash coupon |
| Market Price | Current trading price | Determines entry cost |
| YTM | Annualised yield implied by price and cash flows | Better comparison across bonds |
| Maturity | Date principal is due | Helps match cash-flow goals |
| Credit Rating | External credit-risk opinion | Starting point for issuer analysis |
| Duration | Price sensitivity to rates | Higher duration usually means higher rate sensitivity |
Bond Risk Checklist
| Risk | What to check | Possible mitigation |
| Credit risk | Rating rationale, leverage, cash flow | Diversify; prefer stronger issuers for core allocation |
| Interest-rate risk | Maturity/duration | Ladder maturities |
| Liquidity risk | Exchange volumes/platform depth | Avoid relying on early exit |
| Call risk | Call date and terms | Price call option into return expectations |
| Concentration | Issuer exposure | Cap per-issuer allocation |
FAQs on Corporate Bonds
Is YTM the same as guaranteed return?
No. YTM assumes promised cash flows are received and incorporates reinvestment assumptions. Default, early sale, call features and reinvestment can change realised return.
Are AAA corporate bonds risk-free?
No. AAA indicates a very high credit rating, but ratings can change and other risks such as interest-rate and liquidity risk remain.
Can I sell a corporate bond before maturity?
If it is tradable and a buyer is available, yes. The sale price may be above or below your purchase price.
What is an OBPP?
An Online Bond Platform Provider is a regulated online platform that offers eligible debt securities to investors. Verify registration through SEBI/exchange sources.
Are corporate bonds better than FDs?
They have different risk, liquidity, pricing and tax characteristics. Compare issuer risk, maturity, post-tax yield and whether you need deposit-style simplicity.
