Understanding Bonds: Types, Key Terms and How They Work
Summary
Bonds are debt securities that pay a fixed interest at regular intervals and return principal on maturity. The article discusses bond basics, types available in India, investor terminology, associated risks, and a clear comparison of bonds vs. stocks to help one allocate capital more deliberately.
Introduction
Bonds can add stability to a portfolio, offer predictable income, and balance the higher risks that often come with equities. This guide covers how they work, the types available in India, key terminology, associated risks, and how bonds compare with stocks.
What Are Bonds?
Bonds are fixed-income investments where investors lend money to a company or government. In return, the issuer pays regular interest and returns the original amount when the bond matures. Bonds can provide stable income and help diversify an investment portfolio.
In India, two regulators oversee this lending relationship: the RBI handles government bonds and Treasury Bills, while SEBI supervises corporate debt trading on the NSE and BSE. This regulatory split shapes the debt products available to retail investors, ranging from 91-day Treasury Bills to sovereign bonds with maturities of up to 30 or 40 years.
How Do Bonds Work?
The Government of India issues a bond with a face value of ₹1,000, an annual coupon of 7.26%, and a maturity of 10 years. An investor purchasing the bond at its face value of ₹1,000 would receive an annual coupon payment of ₹72.60. The coupon rate and other terms are specified when the bond is issued.
Then there is the secondary market. Bonds trade on exchanges after issuance, and prices move daily. An investor who purchases this bond for ₹940 will still receive ₹72.60 annually and ₹1,000 at maturity, despite purchasing the bond at a ₹60 discount to its face value. In this case, the actual return, the Yield to Maturity (YTM), is greater than 7.26%. If the bond is purchased for ₹1,060, the YTM will be lower than the coupon rate. This is why the coupon rate and yield are different.
One relationship is central to fixed income: bond prices move in the opposite direction of interest rates. When the RBI hikes the repo rate, new bonds will have higher coupons, and existing bonds with lower coupons will be less attractive. Their market prices fall. As interest rates fall, existing bonds with higher coupon rates generally become more valuable. These price fluctuations generally do not affect investors who hold the bond until maturity, provided the issuer fulfills its repayment obligations. Secondary-market investors monitor these price movements closely.
Types of Bonds
Bonds differ in their issuers, interest payment structures, investment tenures, and associated risk levels.
- Government Securities and Treasury Bills: Investors seeking relatively low-risk fixed-income investments often consider government securities. G-Secs are issued by the central and state governments and are generally considered among the lowest-risk fixed-income investments, with some running as long as 40 years. Treasury Bills sit at the other end of the timeline, maturing in just 91, 182, or 364 days.
- Corporate Bonds: Companies use these to raise money without diluting equity. The trade-off for investors is a higher interest rate than G-Secs, paired with real credit risk. Investors should therefore review the CRISIL, ICRA, or CARE credit rating before investing.
- Tax-Free Bonds: A now-discontinued category, previously issued by agencies like NHAI and REC, that let investors earn interest without owing tax on it.
- Sovereign Gold Bonds: Sovereign Gold Bonds: No new SGB tranches have been issued since February 2024, and the government has not announced plans to resume issuance. Existing SGBs remain tradeable on exchanges, are linked to gold prices, and pay a fixed annual interest of 2.50%. From April 1, 2026, tax-free capital gains at maturity apply only to original RBI subscribers, not to secondary market buyers.
- Floating Rate Savings Bonds: Unlike a standard bond with a fixed coupon, these reset periodically, so returns tend to climb when market interest rates do.
Key Bond Terms to Know
The language around bonds is precise. Some of the key bond terms are explained below:
- Face Value: Amount paid back at the time of maturity; usually it is ₹1,000 in India.
- Coupon Rate: The annual interest rate, expressed as a percentage of face value, set at issuance and fixed thereafter.
- Yield to Maturity (YTM): The rate of return an investor receives who buys the bond and holds it until maturity. YTM is calculated based on the bond’s current market price, par value, coupon interest rate and time to maturity.
- Credit Rating: A rating provided by agencies like CRISIL, ICRA, or CARE to indicate the issuer’s ability to meet its repayment obligations. AAA is the best; D is the default.
- Duration: How sensitive a bond’s price is to interest rate changes; the longer the duration, the greater the price swings a bond will experience when rates change.
Benefits and Risks of Bond Investing
Benefits of Bonds
- Income stability: Regular coupon payments can provide a predictable stream of income, making bonds suitable for retirees and investors with planned financial commitments.
- Capital preservation: If a bond is held to maturity, the investor should receive the full face value, provided the issuer does not default.
- Portfolio stability: Bonds can add stability to an investment portfolio.
- Priority in bankruptcy: Bondholders generally have a higher claim on a company’s assets than shareholders if the issuer goes bankrupt.
Risks of Bonds
- Interest rate risk: Bond prices generally fall when interest rates rise. Selling a bond before maturity could therefore result in a loss.
- Inflation risk: Inflation can reduce the purchasing power of fixed coupon payments over time.
- Credit risk: Lower-rated corporate bonds generally carry a higher risk of default.
- Liquidity risk: Bonds issued by smaller companies may be difficult to sell quickly at a fair price.
Bonds vs. Stocks: Which Is Right for You?
Bonds and stocks are very different in the way they pay and protect their investors. A bondholder is a lender. A shareholder owns a part of the company. The issuer of a bond is obligated to pay interest periodically and to repay the principal at maturity. Dividends are paid only if the company wants to and is able to pay them.
Stocks have historically provided the possibility of higher long-term returns but also greater price volatility. For example, the Nifty 50 has historically given higher returns in the long term, while government bonds have tended to give lower but more stable returns.
Bonds can also provide more stability in times of equity-market turbulence. The equity markets plunged in the 2008-09 financial crisis, but holders of government bonds continued to get paid interest as scheduled.
However, bonds are not risk-free, as they are exposed to interest rate, inflation, credit and liquidity risk. In terms of investing, you don’t have to pick between bonds and stocks. Depending on their financial objectives, risk appetite and investment horizon, investors may combine both asset classes. Debt mutual funds also offer a simpler way to get into the bond market.
| Basis | Bonds | Stocks |
| Investment type | Lending money to an issuer | Owning a share of a company |
| Income | Fixed or predetermined coupon payments | Dividends, if declared |
| Return potential | Generally lower but more predictable | Higher potential with greater volatility |
| Risk | Interest rate, credit, inflation and liquidity risk | Market and business risk |
| Bankruptcy claim | Higher claim on assets than shareholders | Paid after creditors |
| Typical role | Income and stability | Long-term growth |
Conclusion
Bonds can provide several advantages when included in an investment portfolio. They can provide scheduled income and the return of principal at maturity, while potentially reducing portfolio volatility during periods of equity-market weakness. For investors with specific financial commitments or limited tolerance for price swings, those properties are directly useful.
Access to India’s retail bond market has expanded through regulated investment platforms and digital distribution channels. Government securities can be accessed without a traditional brokerage intermediary through certain retail investment channels. Regulated platforms provide retail investors with access to corporate bonds across different investment amounts.
Final Takeaways
- Bonds provide a predictable stream of income through regular interest payments and the repayment of principal at maturity.
- Bonds have different risks. G-Secs are generally safer, and corporate bonds yield higher returns.
- YTM provides a more accurate picture of returns because it takes into account the bond’s price, the interest payments and the maturity date.
- Bond prices move in the opposite direction of interest rates. As rates rise, prices tend to fall.
FAQs
What are the main risks of investing in bonds?
Interest rates are the biggest risk. If interest rates rise after you buy a bond, the market value of a bond you bought previously may fall. There is also credit risk (the issuer may not make interest or principal repayments, more common with lower-rated corporate bonds) and inflation risk, where your fixed interest will slowly buy less over time. Credit and inflation risk may still be important, however, the effect of these risks on actual returns may be reduced if the bond is held to maturity.
What is the difference between the coupon rate and yield of a bond?
The coupon rate is the annual interest that is paid on the face value of the bond and is set when the bond is issued. YTM is the return on what you paid for the bond. If bought below par the YTM increases and if bought above par the YTM decreases. YTM is a better measure to compare bonds.
What happens when a bond reaches maturity?
The issuer pays back the full face value and your final coupon payment comes at about the same time. When the principal is paid back at maturity, the bond expires. For something like a 10-year G-Sec, it means you get your original ₹1,000 back, plus 10 years of interest checks.
Are bonds suitable for beginner investors?
Beginners often find government bonds a good starting point, as they generally have a lower credit risk and a simple repayment structure. Investors should consider the credit rating before investing in corporate bonds. That’s why so many beginners instead turn to debt mutual funds, where the fund manager picks and manages the underlying debt securities.
