How to Build a Bond Ladder in India

A bond ladder is a portfolio of bonds with staggered maturity dates. As each bond matures, you reinvest the proceeds into a new bond at the long end. The result: predictable income, automatic reinvestment at prevailing rates, and no single-point interest rate exposure. This guide explains how to build one using Indian bonds — G-Secs, SDLs, and NCDs.

What problem does a bond ladder solve?

Bond investors face two risks in opposite directions:

• Reinvestment risk: If you buy one large long-dated bond and rates fall, you'll be stuck reinvesting coupons at lower rates when the bond eventually matures.
• Price risk (interest rate risk): If you need to sell before maturity and rates have risen, your bond's price will have fallen.

A ladder doesn't eliminate these risks, but it spreads them across time. When rates rise, your maturing bonds can be reinvested at the new, higher rates. When rates fall, you still have existing bonds earning higher yields locked in. You're never fully exposed to a single rate environment.

A ladder also provides liquidity at regular intervals — bonds mature and return principal on a schedule — without forcing you to sell anything at an unfavourable market price.

How a bond ladder works

Imagine you have ₹10 lakh to invest. Instead of putting it all into one 10-year G-Sec, you split it into five equal parts and buy bonds maturing in 2, 4, 6, 8, and 10 years:

Every two years, you have a bond maturing. You reinvest into the furthest rung. Over time, the ladder maintains its structure while you benefit from prevailing rates at each reinvestment point.

Choosing the right bonds for a ladder

The bond types you choose depend on your credit risk appetite and income needs:

G-Secs and SDLs — for sovereign-grade ladders

Central Government Securities and State Development Loans are the cleanest instruments for laddering. Zero default risk (sovereign), predictable semi-annual coupons, and liquid secondary markets (at least for benchmark maturities). You can buy them directly via RBI Retail Direct without a broker.

The yield disadvantage: G-Secs typically yield 6.8–7.5% (as of mid-2026). You won't earn more by taking more risk in this ladder.

PSU bonds — a middle ground

PSU bonds from NTPC, PFC, REC, IRFC, and NABARD are rated AAA and carry an implicit government backing. Yields are typically 20–60 basis points higher than G-Secs. They are listed on BSE and NSE, and secondary market liquidity is reasonable for larger lots. PSU bonds are available via OBPP platforms and brokers.

NCDs — for higher-yield ladders

Corporate NCDs offer higher yields but carry credit risk. For a ladder, stick to AAA or AA+ rated issuers and be cautious about ladder rungs that extend beyond 7–8 years for corporate paper (credit deterioration is harder to predict over longer horizons).

A mixed ladder — G-Secs for the outer rungs (7–15 years) and investment-grade NCDs for the inner rungs (2–6 years) — gives you higher near-term income while keeping tail-risk contained in sovereign paper.

Building a ladder step by step

Step 1: Define your time horizon and rung count

Common structures: 5 rungs × 2 years apart (up to 10 years), or 7 rungs × 1 year apart (up to 7 years). Annual rungs give more frequent reinvestment; biennial rungs reduce transaction overhead.

Step 2: Screen for available bonds at each maturity

Use RetailBonds.in's screener to filter by instrument type and maturity year. For G-Sec rungs, filter to instrument type "G-Sec" and sort by maturity. For NCD rungs, filter by rating tier (AAA or AA) and maturity year range. You'll rarely find a bond maturing exactly on your target date — find the nearest available maturity within 6–12 months of each rung.

Step 3: Check minimum investment amounts

G-Secs via RBI Retail Direct: ₹10,000 minimum per transaction. NCDs via OBPP: ₹10,000 minimum (reduced from ₹1 lakh in 2024). Brokerage accounts may have different lot sizes for secondary market purchases.

Step 4: Budget for reinvestment

Decide ahead of time: when a rung matures, will you reinvest the full principal (and allocate coupons elsewhere), or will you also redirect coupon income into the ladder? The latter compounds faster but requires tracking many small amounts.

Step 5: Maintain and review annually

Once a year, review: is the credit quality of your NCD rungs intact? Has a rating agency downgraded any issuer? Are there better bonds available at the next maturity you'll be reinvesting in? A ladder is low-maintenance but not zero-maintenance.

What a ladder doesn't solve

• Inflation risk: Fixed coupon bonds lose purchasing power if inflation rises faster than your yield. Ladder returns are in nominal terms.
• Credit risk: Ladders with corporate NCDs can suffer unexpected losses if an issuer defaults. No laddering structure prevents that.
• Liquidity within rungs: If you need to access capital before a rung matures, you may have to sell at market price, which could be below face value.
• Tax drag: Coupon income is taxed as interest income at your slab rate every year. LTCG applies to capital gains on bonds held over 12 months (36 months for unlisted bonds), but coupon income is ordinary income regardless of holding period.

Is a ladder right for you?

Bond ladders work well when you have:

• A known future liquidity need at specific dates (children's education, retirement corpus withdrawal, home purchase)
• Regular income requirements that you want to smooth over time
• A medium-to-long-term investment horizon (5–15 years)
• A preference for predictability over maximum return optimisation

A ladder is less useful for short-term investors (under 3 years) or for investors who actively want to trade around interest rate movements — in that case, duration management and bond funds may be more appropriate instruments.
