How to Build a Long-Term Bond Portfolio Using BondScanner

Saurabh Mukherjee 27 November 2025


Introduction

Long-term bond portfolios are designed with extended horizons—often 5, 10, 15, or 20 years—depending on the investor’s financial goals and risk profile.

While the Indian bond market offers many long-tenor instruments, the key challenge is navigating issuer choices, maturity structures, and bond features efficiently.

BondScanner provides a transparent, structured interface that helps users explore long-term bond options through filters, maturity tools, issuer data, disclosures, and yield snapshots (when available).

This article explains how to build a long-term bond portfolio using BondScanner, presented neutrally and in compliance with OBPP regulations.

What Is a Long-Term Bond Portfolio?

A long-term bond portfolio typically includes instruments with maturities such as:

  • 7 years

  • 10 years

  • 15 years

  • 20 years

  • 30 years (in some government securities)

Long-term portfolios may include:

  • Government securities (G-Secs)

  • State Development Loans (SDLs)

  • PSU bonds

  • High-rated corporate bonds

  • Perpetual bonds (with regulatory considerations)

  • Infrastructure bonds

  • Securitised instruments with long tenors

Long-term portfolios focus on stability of cash flows, predictability of maturity timelines, and clarity of structure—not on performance guarantees.

Why Long-Term Planning Matters

Long-term fixed-income planning helps:

  • structure cash flows

  • understand interest-rate sensitivity

  • align maturities with future needs

  • diversify across issuers and sectors

  • maintain predictable timelines for reinvestment

  • interpret risk factors through duration and credit analysis

BondScanner provides the tools to analyse these characteristics clearly.

Using BondScanner as a Discovery Tool

BondScanner offers:

  • advanced filters for rating, tenor, issuer type

  • maturity timelines

  • yield indicators (if available from exchanges)

  • bond structure summaries

  • issuer details

  • offer document visibility

  • security-type classification

  • real-time market data integrations (where applicable)

These features support structured exploration of long-term bonds.

Step 1: Define Your Time Horizon

Before selecting bonds, users benefit from clarifying:

  • intended horizon (5, 10, 15+ years)

  • expected liquidity requirements

  • sensitivity to long-duration exposure

  • risk tolerance for interest-rate movements

This helps decide whether to focus on intermediate (5–10 year) or extended (10–20 year) maturities.

Step 2: Use Filters to Explore Long-Term Instruments

BondScanner’s filters allow users to identify long-term bonds quickly.

Recommended Filter Categories for Long-Term Exploration:

  • Tenor: 7+ years

  • Rating: AAA, AA, A (user-defined)

  • Issuer Type: PSU, Government, Corporate

  • Coupon Type: Fixed or step-up

  • Security Type: Secured, unsecured, subordinated

  • Listing Status: Listed bonds for visibility

Filters help users narrow the universe to long-tenor options.

Step 3: Understand Ratings & Issuer Categories

BondScanner displays credit ratings for every bond:

  • AAA

  • AA+

  • AA

  • A and below

  • Structured/securitised ratings

Issuer categories to explore:

  • Government securities (central)

  • SDLs (state)

  • PSUs and quasi-sovereign issuers

  • Corporate issuers

  • Financial institutions

  • Infrastructure-focused entities

Understanding issuer type helps interpret credit characteristics without making any judgement on risk or suitability.

Step 4: Evaluate Maturity Profiles & Duration Exposure

Long-term bonds carry higher duration—meaning greater sensitivity to interest-rate changes.

BondScanner’s maturity tools show:

  • exact maturity date

  • remaining time to maturity

  • intermediate cash flows

  • whether the bond has staggered amortisation

This helps evaluate long-term behaviour of the bond’s cash flows.

Step 5: Analyse Call, Put & Step-Up Features

Long-term bonds may include optionality features that affect timelines:

Call Options

Issuer can redeem early.

Put Options

Investor can exit at specific dates (if applicable).

Step-Up Coupons

Coupon rates increase at predefined intervals.

BondScanner displays:

  • call schedule

  • put schedule

  • step-up dates

  • impact on yield indicators

Understanding optionality is essential for long-term planning.

Step 6: Review Yield Indicators & Pricing Data

Where available, BondScanner shows yield-related information based on regulated sources:

  • YTM (Yield to Maturity)

  • YTC (Yield to Call)

  • yield ranges

  • price indications

  • traded volumes

These indicators help users evaluate relative differences among long-term bonds.

They are not forecasts or guaranteed outcomes.

Step 7: Study Security Type & Ranking

For long-term portfolios, understanding security level is essential.

BondScanner highlights:

  • Secured bonds (charge on assets)

  • Unsecured bonds (general credit strength)

  • Subordinated/Tier-2 instruments

  • Perpetual/AT1 characteristics

  • Government securities with sovereign backing

Security classification helps users interpret repayment hierarchy.

Step 8: Compare Bonds Using BondScanner Tools

BondScanner provides comparison tools showing:

  • coupon

  • maturity

  • issuer type

  • security classification

  • rating

  • market data snapshots

  • call/put schedules

This is useful for comparing:

  • two 10-year PSU bonds

  • a 15-year SDL versus a long-dated G-Sec

  • different corporate issuers with similar tenors

The comparison functionality remains purely informational.

Step 9: Review Offer Documents & Risk Disclosures

For long-term bonds, documents contain essential information such as:

  • covenants

  • risk factors

  • call/put clauses

  • security details

  • project or asset information

  • financial disclosures

  • redemption structure

BondScanner links directly to:

  • offer documents

  • term sheets

  • regulatory filings

Document review ensures investors understand the fine print.

Framework Example: Building a 10–15 Year Portfolio

(Illustrative, neutral, not a recommendation)

A user exploring a balanced long-term profile may look at:

1. Government Securities (G-Secs)

Long-tenor (10–15 years) depending on issuance calendar.

2. State Development Loans (SDLs)

10-year maturities with clear auction-based issuance.

3. PSU Bonds

10–15 year secured bonds from large PSUs.

4. Corporate Bonds

Long-term bonds from high-rated companies.

This is only an illustrative structure to demonstrate how BondScanner can be used for diversification across tenors and issuer types.

Common Mistakes to Avoid

Users building long-term bond portfolios should avoid:

1. Focusing only on yield

Long duration increases interest-rate sensitivity.

2. Ignoring call features

Callability can shorten actual holding periods.

3. Overlooking issuer documents

Risk factors and covenants are essential.

4. Not reviewing listing status

Liquidity varies across instruments.

5. Not diversifying across issuer types

Concentration risk may increase exposure to sector-specific developments.

These considerations help maintain a structured approach.

Conclusion

A long-term bond portfolio requires careful exploration of maturity profiles, issuer categories, security types, ratings, and optionality features.

BondScanner’s tools make this exploration easier by offering transparent filters, yield indicators, maturity visuals, issuer data, bond structure summaries, and access to disclosures—all within the SEBI-compliant OBPP framework.

By combining structured discovery with responsible information access, investors can understand long-term bond characteristics more clearly.
