Constant Maturity Gilt Fund: A Practical Guide

A Constant Maturity Gilt Fund is a special type of gilt fund that maintains a fixed Macaulay duration of 10 years. It invests in government bonds with this specific maturity profile. Indian investors use these funds for stable long-term debt exposure.

This guide explains how Constant Maturity Gilt Funds work and how to use them.

What Is a Constant Maturity Gilt Fund?

This fund invests in government bonds while keeping the portfolio duration close to 10 years. The fund manager rebalances regularly to maintain this duration.

SEBI rules require a Macaulay duration of around 10 years.

How They Work

When you invest:

• The AMC pools money from many investors
• The fund manager picks government bonds totaling about 10 years duration
• The NAV reflects interest rate changes
• Portfolio is rebalanced as bonds approach maturity

The fixed duration gives a predictable rate-sensitivity profile.

Why These Funds Matter

Constant maturity gilt funds matter for three reasons:

1. They keep duration steady at 10 years
2. They offer pure government bond exposure
3. They suit long-term rate-cycle investors

A clean fund offers consistent rate exposure.

Benefits

These funds offer:

1. Zero credit risk
2. Predictable interest rate exposure
3. Suitable for long-term debt views
4. Steady income from government bonds

They suit investors with a long horizon.

Risks

Risks include:

• High interest rate sensitivity
• NAV falls when rates rise
• Returns are not fixed
• Tax impact

A clear plan helps manage these.

How to Invest

A common method:

1. Build a view on long-term interest rates
2. Pick a quality constant maturity gilt fund

A clean plan avoids these errors.

Constant Maturity Gilt vs Regular Gilt Funds

The two differ:

• Regular gilt: variable duration
• Constant maturity: fixed at 10 years

The constant maturity version is more predictable.

Constant Maturity Gilt vs Long Duration Funds

The two differ:

• Constant maturity gilt: only government, fixed 10-year duration
• Long duration funds: includes corporate bonds

Gilt funds have zero credit risk.

Asset Allocation Role

Constant maturity gilt funds form part of long-term safe debt allocation. Combine with equity, gold, and cash for full asset allocation.
