The secondary market is where bonds trade after they are issued. In India it is dominated by institutions, most bonds barely trade, and quoted prices can be stale. That shapes what you should reasonably expect as a retail buyer or seller.
Primary versus secondary
The primary market is the initial sale. A company issues bonds and raises money, either through a public issue at par or a private placement to institutions. Once that is done, the company has its money and is out of the picture except for paying coupons.
The secondary market is everyone trading those bonds among themselves afterwards. No new money reaches the issuer. This is where you buy a bond that was issued three years ago, and where you sell one before its maturity.
Who is actually trading
The Indian corporate bond market is overwhelmingly institutional. The large holders:
| Holder | Why they hold bonds | Trading behaviour |
|---|---|---|
| Insurance companies | Match very long-dated liabilities | Buy and hold to maturity |
| Pension and provident funds | Long horizons, predictable payouts | Buy and hold |
| Banks | Statutory and liquidity requirements | Mostly hold |
| Mutual funds | Deliver returns to unit-holders | The most active traders, but constrained by redemption flows |
The common thread: most of this money buys bonds to hold them, not to trade them. That single fact explains most of what follows.
Why liquidity is thin
- Buy-and-hold dominance. If the largest holders never sell, there is not much supply changing hands.
- Fragmentation. Instead of a few large benchmark issues that everyone trades, India has thousands of small private placements, each with its own coupon, maturity and terms. Trading interest that might have concentrated in a handful of liquid bonds is spread across thousands of illiquid ones.
- Structural bias to primary. A large share of issuance is privately placed straight to institutions who hold it. It never really enters active secondary circulation.
The result: a majority of listed corporate bonds trade infrequently. Many go days or weeks between trades. Some do not trade for months.
What thin liquidity means for you
Quoted prices can be stale. A last traded price from three weeks ago is not a reliable guide to what the bond is worth today, especially if rates or the issuer's situation have moved since. Always check the trade date next to the price. How to read a bond listing covers which fields to trust.
Spreads are wide. The gap between what a buyer will pay and what a seller will accept can be far wider than in equities. A seller in a hurry accepts a discount. A buyer in a hurry pays up. That spread is a real cost, usually larger than any brokerage.
Exiting early is not guaranteed. You can place a sell order any time the market is open, but there may be no buyer in your quantity at a price you will accept. Plan around holding to maturity. Treat an early exit as a possibility, not a feature.
Size matters against you. A small retail lot may actually be easier to place than a large one, because it can be absorbed without moving the price. But an odd lot can also be shunned. Neither direction is reliable.
How to work with it
- Assume maturity is your horizon. Buy bonds whose redemption date matches when you will need the money. A bond ladder engineers regular cash returns through maturities so you never depend on selling.
- Use aggregated trade data, not a single quote. Reported trades across the market give a better picture of fair value than one stale last price. EZBond aggregates NSE and NSDL reported data, prices, yields and volumes by ISIN, for exactly this reason.
- Value the bond yourself. Run the price you are quoted through the bond yield calculator and compare the resulting yield against comparable bonds. If a bond consistently trades cheaper than its calculated fair value, that is information about liquidity or the issuer, not an arbitrage.
- Factor the spread into the decision. If you might realistically need to sell early, the cost of crossing a wide spread should be part of your yield expectation, not a surprise later.
Is it improving?
SEBI and the exchanges have taken steps aimed at deepening the market. A request-for-quote platform for institutional trading, tighter disclosure norms, the OBPP framework to bring retail distribution into a regulated structure, and periodic reductions in minimum face value to widen participation. These help at the margin. The structural pattern, buy-and-hold institutions and fragmented issuance, changes slowly, and for now a retail investor should plan for illiquidity rather than assume it away.
The takeaway
India's secondary corporate bond market is institutional, buy-and-hold, and fragmented, so most bonds trade rarely and quoted prices can be old. Buy bonds you can hold to maturity, judge value from aggregated trade data rather than a single quote, and price the wide bid-ask spread into any plan that involves selling early.
