What are Debt Funds?

A debt fund is a mutual fund that invests in debt instruments. There are different types of debt funds to suit investors with varying risk-return profiles, investment horizons, and financial goals. Debt funds invest in all kinds of debt, such as treasury-bills, government securities, commercial paper, certificates of deposits, money market instruments, securitized debt, and corporate bonds.

The key difference between a debt fund and an equity fund is that they invest in different asset classes. Equity funds invest 65% or more of their assets into equity and equity-linked products, while debt funds hold mainly bonds and cash assets. Remember that the value of an investment depends on the prices of the securities that make up the investment. Since bond prices tend to be less volatile than stock prices, debt fund values are more stable than the value of equity funds. In other words, debt funds are considered to be less risky, especially when held for short periods of time.

1. Types of Debt Funds

Overnight Funds:

Overnight Funds invest in securities having a maturity of 1 day, typically money market instruments. These funds aim to provide liquidity and convenience, rather than high returns. They are suitable for investors (mainly corporate treasuries) looking to park funds for a very short period.

Liquid Funds:

Liquid Funds invest in debt securities with less than 91 days to maturity. They are suitable for investors who want to park temporary cash surpluses for a few days, as they provide steady returns with minimum NAV volatility.

Ultra-short Duration Funds:

Ultra-short Duration Funds are suitable for investors who have an investment horizon of at least 3 months. These funds earn slightly higher yields than liquid funds and are considered to be a low risk investment. Some ultra-short duration funds may invest in lower-rated bonds to push up their yields.

Low Duration Funds:

Low Duration Funds are moderately risky and provide reasonable returns. They are useful for those looking to invest for around 6 months to one year. Their portfolio may include bonds with a weaker credit rating to kick up yields.

Money Market Funds:

Money Market Funds invest in debt instruments with maturity upto one year. They aim to generate returns from interest income, while their slightly longer duration offers some scope for capital gains.

Short Duration Funds:

Short Duration Funds invest in a judicious combination of short and long-term debt, as well as across credit ratings. These funds are recommended for investment horizons of 1-3 years. They usually earn higher returns than liquid and ultra-short duration funds, but also show more NAV fluctuations.

2. Why invest in debt funds?

Debt funds offer many benefits, especially to retail investors, or to investors who have traditionally kept their money in bank deposits.

  • Access to Professional Expertise and Market Returns:

    Investing in a debt fund offers the opportunity to earn interest as well capital gains from debt. It allows retail investors to access money markets or wholesale debt markets- segments in which they cannot directly invest.
  • Lowers Portfolio Risk:

    Since debt funds are less risky than equity funds, a strategic allocation to the best performing debt funds reduces risk and brings stability to an investment portfolio. Tactical investments in debt funds are useful to take advantage of temporary yield opportunities.
  • Range of investment options:

    Debt funds are available along the entire spectrum of maturity and credit risk. Shorter duration funds generate regular and stable income. Longer duration funds earn from interest income as well as capital gains, and suit investors who can take on higher NAV volatility. Overnight funds, liquid funds, corporate bond funds and low duration funds tend to invest in the safest debt products. Ultra-short and short duration funds may be structured to take on credit risk to provide higher returns.
  • Liquidity:

    Debt funds are very liquid, and can be redeemed easily, usually within one or two working days of placing the redemption request. Unlike bank fixed deposits or recurring deposits, there is no lock-in period. While a few funds may impose a small exit load for early withdrawal, in general, there are no penalties when a mutual fund investment is withdrawn.
  • Low Cost Investment:

    According the SEBI norms, the total expense ratio of a debt fund cannot exceed 2% of Assets under Management. Among debt funds, overnight and liquid funds have very low expense ratios, while dynamic and long-term funds charge higher expense ratios.
