Bonds in India: Key Terms Every Investor Should Know

The bond market in India is gaining more attention than ever before. With government securities, corporate bonds, and new investment platforms opening doors to retail and global investors, understanding bond-related terms has become crucial for making informed investment decisions.

If you are new to bonds or looking to refine your fixed-income strategy, you will often come across terms like bps, ISIN, security, maturity date, face value, coupon rate, coupon frequency, credit rating, and more. Each plays a role in how bonds are priced, traded, and valued.

This guide breaks down these key terms in simple, practical language so you can navigate the bond market with confidence.

Bond Market India: The Basics

The bond market in India is where governments, corporations, and institutions issue debt securities to raise money. Investors who buy these bonds lend their money in exchange for regular interest payments and the eventual return of principal on maturity.

Bonds are considered relatively safer than equities, but understanding their structure and terminology is essential to avoid surprises and make smarter choices.

Key Bond Market Terms Every Investor Should Know

1. Basis Points (bps)

• Meaning: A unit to measure changes in interest rates or yields.

• 1 bps = 0.01%

• Example: If a bond’s yield increases from 6.50% to 6.75%, it has risen by 25 bps.

• Why It Matters: Even small changes in interest rates can significantly affect bond prices, especially for long-term bonds.

2. ISIN (International Securities Identification Number)

• Meaning: A 12-character alphanumeric code that uniquely identifies a bond.

• Example: IN0020250075 might refer to a specific Government of India bond maturing in 2025.

• Why It Matters: Helps investors track, verify, and settle transactions accurately in the bond market.

3. Security

• Meaning: In bond terms, “security” refers to the specific debt instrument you are investing in, such as a Government Security (G-Sec), Corporate Bond, or State Development Loan.

• Why It Matters: Different securities carry different risks, returns, and tax treatments.

4. Maturity Date

• Meaning: The date on which the bond issuer repays the principal amount to the bondholder.

• Example: A 10-year bond issued in 2023 will mature in 2033.

• Why It Matters: Bonds with longer maturities are more sensitive to interest rate changes.

5. Last Interest Payment Date

• Meaning: The most recent date on which the bond paid interest to investors.

• Example: If a bond pays interest semi-annually in June and December, the last interest payment date might be 30 June 2025.

• Why It Matters: Useful for calculating accrued interest if you buy or sell bonds between payment dates.

6. Next Interest Payment Date

• Meaning: The upcoming scheduled date for interest payment.

• Example: Continuing the above case, the next date would be 31 December 2025.

• Why It Matters: Helps investors plan cash flows from their bond investments.

7. Face Value (Par Value)

• Meaning: The nominal value of a bond, usually ₹1,000 in India, which is repaid at maturity.

• Why It Matters: Interest payments are calculated as a percentage of face value, and price premiums or discounts are measured against it.

8. Coupon Rate

• Meaning: The fixed annual interest rate the bond pays, expressed as a percentage of face value.

• Example: A 7% coupon on a ₹1,000 bond pays ₹70 annually.

• Why It Matters: Higher coupon rates mean higher regular income, but market prices may adjust based on prevailing rates.

9. Coupon Frequency

• Meaning: How often the bond issuer pays interest.

• Common Frequencies: Annual, semi-annual, or quarterly.

• Why It Matters: Determines how often you receive income and affects compounding returns.

10. Credit Rating

• Meaning: An independent assessment of the issuer’s ability to repay the bond, usually provided by agencies like CRISIL, ICRA, or CARE in India.

• Scale Example: AAA (highest safety) to D (default).

• Why It Matters: Higher ratings usually mean lower yields but more safety, while lower ratings carry higher yields but greater risk.

Why These Terms Matter for Investors?

Understanding these terms is not just about jargon, it’s about making better decisions.

• Pricing Impact: Changes in bps affect yields and market prices.

• Risk Assessment: Credit ratings and maturity dates help you judge default and interest rate risks.

• Liquidity Planning: Knowing interest payment dates aids in cash flow planning.

• Portfolio Strategy: Matching coupon frequency and type of security to your investment goals ensures better returns.

Let’s say you come across the following details on a bond:

• Security: Government of India 2030 G-Sec

• ISIN: IN0020300123

• Coupon Rate: 6.85%

• Coupon Frequency: Semi-annual

• Credit Rating: Sovereign (Highest Safety)

• Maturity Date: 30 June 2030

• Last Interest Payment Date: 30 June 2025

• Next Interest Payment Date: 31 December 2025

With this, you immediately know how much interest you’ll earn, when you’ll get paid, and how safe the bond is.
