The universe of debt funds is vast, with SEBI defining 16 distinct categories to cater to various investment horizons and risk appetites.
For a beginner, this can seem overwhelming. However, these categories can be grouped into logical buckets based on the two key risks: interest rate risk (managed through duration) and credit risk.
A simple way to understand the categories based on duration is to remember the rule: the longer the fund's duration, the more sensitive it is to interest rate changes.
1. Funds for Very Short-Term Goals (Ultra-Low Risk)
These funds are designed for parking money for a few days to a few months, with the highest priority on safety and liquidity.
Overnight Fund: Invests in securities that mature in just one day.
It has negligible interest rate and credit risk, making it the safest category.
Liquid Fund: Invests in debt and money market instruments with a maturity of up to 91 days.
It offers slightly higher returns than an overnight fund with very low risk.
Ideal for building an emergency fund or parking money for a few weeks or months.
2. Funds for Short-Term Goals (Low to Moderate Risk)
These funds are suitable for goals that are between 3 months and 3 years away.
They take on slightly more interest rate risk to generate better returns.
Ultra-Short Duration Fund: Portfolio Macaulay duration between 3 to 6 months.
Low Duration Fund: Portfolio Macaulay duration between 6 to 12 months.
Money Market Fund: Invests in high-quality money market instruments with a maturity of up to 1 year.
Short Duration Fund: Portfolio Macaulay duration between 1 to 3 years.
A popular choice for goals that are 2-3 years away.
3. Funds for Medium to Long-Term Goals (Higher Interest Rate Risk)
These funds invest in longer-maturity bonds and are suitable for investors with a longer time horizon who can tolerate higher NAV volatility due to interest rate movements.
Medium Duration Fund: Portfolio Macaulay duration between 3 to 4 years.
Medium to Long Duration Fund: Portfolio Macaulay duration between 4 to 7 years.
Long Duration Fund: Portfolio Macaulay duration greater than 7 years.
4. Specialty Funds (Based on Credit Risk or Issuer Type)
These funds follow specific investment mandates related to the type of bonds they hold.
Corporate Bond Fund: Must invest at least 80% of its assets in the highest-rated corporate bonds (AA+ and above).
It takes on minimal credit risk.
Credit Risk Fund: Must invest at least 65% of its assets in corporate bonds rated below the highest quality (AA or lower).
It intentionally takes on higher credit risk in pursuit of higher yields.
This is a high-risk category not suitable for beginners.
Gilt Fund: Invests a minimum of 80% in government securities (G-Secs).
These funds have zero credit risk (as the government is the borrower) but can have high interest rate risk depending on the maturity of the G-Secs they hold.
Banking and PSU Fund: Invests at least 80% in debt instruments of banks, Public Sector Undertakings, and Public Financial Institutions, which are generally considered high-quality issuers.
Dynamic Bond Fund: The fund manager actively manages the portfolio's duration, shortening it when they expect interest rates to rise and lengthening it when they expect rates to fall.
Floater Fund: Invests at least 65% in floating rate instruments, whose interest payments adjust to changes in market rates.
This helps to minimize interest rate risk.
By matching your investment time horizon to the fund's duration profile, you can select the most appropriate debt fund for your specific financial goal.
