← Writing / Debt & Fixed Income
A bond is a loan. You lend money to a government or a company. They pay you interest at regular intervals. At the end of the agreed period, they return your principal. That’s the whole idea. The complexity comes in the details, who is borrowing, what rate they’re paying, and what happens if you want your money back before the bond matures.
Most retail investors in India have very little direct exposure to bonds, and most financial conversations in this country are so equity-heavy that bonds feel like a foreign concept. That’s a mistake worth correcting, not because bonds are exciting, but because they serve a function in a portfolio that equity cannot.
The Basic Mechanics
When you buy a bond, three things are fixed at issuance: the face value (also called par value, usually ₹1,000 or ₹100), the coupon rate (the annual interest rate expressed as a percentage of face value), and the maturity date (when the borrower returns your principal).
Example: you buy a bond with face value ₹1,000, coupon rate 7 percent, maturity in 10 years. Every year you receive ₹70 in interest (7 percent of ₹1,000). After 10 years, you get ₹1,000 back. Simple and predictable.
The complication arrives if you want to sell the bond before maturity. The bond now trades in the secondary market, and its price will be different from ₹1,000, it will depend on what interest rates are doing in the economy at that time. This is the inverse relationship between bond prices and yields, which is the most important concept in fixed income.
Bond Prices and Yields, The Inverse Relationship Explained
Let’s stay with that example. You bought a bond at ₹1,000 paying 7 percent per year. Two years later, the RBI has raised interest rates and new bonds are now being issued at 9 percent. Nobody will pay you ₹1,000 for your old bond when they can get a 9 percent bond at par. They’ll only buy your bond at a discount, a price low enough that the ₹70 annual interest represents a 9 percent yield on what they’re actually paying.
Work it out: if someone pays ₹778 for your bond and receives ₹70 per year, that’s approximately 9 percent yield. So your bond’s market price has fallen from ₹1,000 to around ₹778, even though nothing about the bond itself has changed. The issuer hasn’t defaulted. The coupon hasn’t changed. It’s just that the market environment has shifted and your bond’s fixed return looks less attractive relative to new issuances.
Now run it the other way. If rates fall from 7 to 5 percent after you buy, your 7 percent bond looks attractive. People will pay more than ₹1,000 for it, the price rises above par. This is why bond investors celebrate when rates fall: existing bonds become worth more.
Price up, yield down. Price down, yield up. These always move opposite to each other, by definition.
Government Bonds: G-Secs, T-Bills, and SDLs
The safest bonds in India are issued by the central government. These are called Government Securities, or G-Secs. The government is not going to default on a rupee-denominated obligation, it can always print more rupees if it has to, which makes these instruments as close to risk-free as you can get in the domestic market.
Treasury Bills (T-Bills) are short-term government instruments, 91, 182, or 364-day tenures. They’re issued at a discount and redeemed at face value. No coupon payments; the return is the difference between what you pay and what you receive at maturity.
State Development Loans (SDLs) are bonds issued by individual state governments, Maharashtra, Tamil Nadu, Karnataka, and so on. They yield slightly more than central government bonds because there’s a marginal perception of higher risk, though in practice defaults by Indian state governments are extremely rare.
Retail investors can now buy G-Secs directly through the RBI Retail Direct platform, which removed the intermediary requirement that had historically kept individual investors out of this market.
Corporate Bonds: NCDs and Debentures
Companies borrow money through bonds too. In India, corporate bonds are often issued as Non-Convertible Debentures (NCDs). The “non-convertible” part means they cannot be converted into equity, unlike convertible debentures, which can turn into shares under certain conditions.
Corporate NCDs yield more than government bonds to compensate for credit risk, the possibility that the company might not repay. A well-rated company (AAA or AA+) might yield 7.5 to 8.5 percent when government bonds yield 7 percent. A lower-rated company might offer 10 to 12 percent, but that premium exists because the market perceives real default probability.
Credit ratings (by CRISIL, ICRA, CARE) are the primary tool for evaluating corporate bond quality. They’re not infallible, IL&FS was AAA rated before its collapse in 2018, but they’re a starting point. Don’t reach for yield by going down the credit quality curve without understanding what you’re accepting.
Why Retail Investors Ignore Bonds
The equity market has all the stories. Multibaggers, turnaround plays, smallcap discoveries, equity investing has a narrative quality that bonds simply don’t. A bond that pays you 7.5 percent per year and returns your principal in five years is the financial equivalent of a good night’s sleep. Useful, essential, not interesting enough to post about.
The result is that most retail investors in India have their safe money sitting in FDs while their risky money is in equity. The middle ground, bonds with credit risk higher than government paper but lower than equity risk, is largely absent from retail portfolios. This leaves people either with too much idle safety (FDs eating into real returns after inflation) or too much equity risk when they should be smoothing out volatility with fixed income.
The same instinct that makes people treat gold as boring until it suddenly isn’t, which I’ve written about in my gold piece, applies to bonds. The quiet instruments don’t get attention until something goes wrong and people suddenly need the stability they didn’t think they’d want.
Duration: How Interest Rate Sensitive Is Your Bond?
Duration is a measure of how sensitive a bond’s price is to changes in interest rates. A bond with a duration of 5 means that if interest rates rise by 1 percent, the bond’s price will fall by approximately 5 percent. Long-duration bonds (10+ year maturities) are more sensitive to rate changes than short-duration bonds (1 to 3 year maturities).
For retail investors who want bond exposure without getting caught in rate cycles, short-duration funds or holding bonds to maturity are the simplest approaches. If you hold to maturity, you don’t care what happens to the bond’s market price along the way, you’ll get your promised coupon and return your principal regardless.
If you’re buying through a bond fund (which is how most retail investors access this market), the fund manager handles the duration and credit decisions for you, but you’re exposed to NAV fluctuations based on rate movements.
How to Access Bonds as a Retail Investor
There are a few routes. The simplest is through debt mutual funds, short duration, medium duration, gilt funds, credit risk funds. These pool investor money and invest in a diversified bond portfolio, giving you professional management and liquidity.
For direct government bond investing, RBI Retail Direct is the clearest path. You open an account, link your bank, and can bid at government bond auctions or buy existing bonds in the secondary market. The interface has improved significantly since launch.
For corporate NCDs, public issues are periodically announced and you can subscribe through your demat account, similar to an IPO. Secondary market trading is thinner for bonds than equity, but it exists on NSE and BSE.
The connection between understanding bonds and building a durable financial structure is the same one I return to in farming and money, the idea that different assets serve different seasons and purposes, and the quiet, steady ones often carry more weight than they get credit for.
Bonds vs FDs: What’s the Actual Difference?
This question comes up often. Both are fixed income instruments. The differences are liquidity, yield, and flexibility.
FDs are more accessible and simpler. You can break them early with a small penalty. DICGC insures up to ₹5 lakh per depositor per bank. The return is clear and there’s no market risk to the principal if you hold to maturity.
Bonds, especially government bonds, carry no credit risk and often offer marginally better yields than bank FDs at equivalent tenures. But their price fluctuates in the secondary market, and accessing them requires a demat account and some familiarity with how to trade them.
For most retail investors, the practical answer is that FDs and debt mutual funds cover the fixed income need adequately. Direct bond investing makes more sense as you accumulate a larger portfolio and want more granular control over duration and credit exposure.
Practical takeaway: bonds are not a substitute for equity returns, they’re a stabiliser for the portion of your money that cannot afford significant drawdowns. Even a modest allocation to G-Secs or short-duration debt funds provides a buffer when equity corrects, and that buffer is more valuable than most investors realise until they need it.
