The debt market is often considered by investors seeking relatively lower volatility and income potential. It is an integral part of the capital market ecosystem. Indian investors exploring debt funds may view them as a route to participate in fixed-income securities.
While certain debt fund categories may exhibit relatively lower volatility than equity-oriented investments, debt funds remain market-linked instruments and do not offer assured returns. In some market conditions, debt funds may offer different return outcomes compared to traditional bank deposits, although return outcomes are not guaranteed.
What is a debt fund in mutual funds?
In simple terms, a debt fund is a category of mutual fund that invests primarily in fixed-income securities. These securities include government securities, treasury bills, commercial papers, corporate bonds, certificates of deposit, and other money market instruments.
Investors may earn potential returns through interest income generated by these securities and through changes in the market value of the underlying instruments. Although the Net Asset Value (NAV) of debt funds fluctuates with changes in interest rates and market conditions, many debt fund categories are generally considered relatively less volatile than equities and derivatives.
The fundamental difference between debt funds and equity funds lies in the nature of the underlying investments. Equity investments represent ownership in companies, whereas debt funds invest in debt instruments issued by governments, financial institutions, and corporations. Fund managers allocate pooled investor money across such instruments in line with the scheme mandate.
The core objective of debt funds is to provide potential income generation along with relatively lower volatility compared to equity-oriented investments in certain scenarios. For retail investors, debt funds also provide access to institutional debt instruments that may otherwise require larger investment amounts in the direct bond market.
Features of debt mutual funds
The functioning of debt funds is generally based on three broad aspects: suitability, potential return generation, and risk management.
Suitability
Debt funds may be considered by investors with low-to-moderate risk appetite or those pursuing short-to-medium-term financial goals. In some cases, they may also help diversify portfolios during periods of equity market volatility.
For example, investors approaching retirement may allocate a portion of their portfolio to debt-oriented investments in an attempt to reduce overall portfolio volatility compared to equities.
Returns
Potential returns from debt funds generally arise from two sources:
- Interest income: Debt instruments in the portfolio generate coupon payments or interest income, which contributes to the overall portfolio return.
- Capital gains: Capital appreciation may occur when the market value of bonds rises, which may happen when broader market interest rates decline.
Risks
Debt funds carry various risks that investors should understand before investing.
- Interest rate risk: Bond prices and interest rates generally move inversely. When interest rates rise, bond prices may decline, which may reduce the fund’s NAV.
- Credit risk: This refers to the possibility that the issuer of a debt instrument may fail to meet interest payment obligations or repay the principal amount on time.
- Liquidity risk: Liquidity risk arises when a fund manager faces difficulty in selling securities in the market without materially impacting prices.
What are the types of debt funds?
To help investors align investments with their time horizons, SEBI categorises debt funds based on the maturity profile and credit quality of the underlying securities.
| Category | Profile |
| Overnight Fund | Maturity of 1 day |
| Liquid Fund | Maturity of up to 91 days |
| Ultra Short Duration Fund | Maturity between 3 months and 6 months |
| Low Duration Fund | Maturity between 6 months and 12 months |
| Money Market Fund | Maturity up to 1 year |
| Short Duration Fund | Maturity between 1 year and 3 years |
| Medium Duration Fund | Maturity between 3 years and 4 years |
| Medium to Long Duration Fund | Maturity between 4 years and 7 years |
| Long Duration Fund | Maturity above 7 years |
| Dynamic Bond Fund | Investment across duration profiles |
| Corporate Bond Fund | Minimum investment of 80% in corporate bonds rated AA+ or above |
| Credit Risk Fund | Minimum investment of 65% in corporate bonds rated AA or below |
| Gilt Fund | Minimum investment of 80% in government securities across maturity |
| Gilt Fund with 10-year Constant Duration | Minimum investment of 80% in government securities with 10-year duration |
| Banking and PSU Fund | Minimum investment of 80% in bonds issued by banks, PSUs, public financial institutions, and municipal bodies |
| Floater Fund | Minimum investment of 65% in floating rate instruments |
How does a debt mutual fund work?
The functioning of debt funds is closely linked to the Reserve Bank of India’s (RBI) monetary policy and interest rate movements. When investors purchase units of a debt fund, the Asset Management Company (AMC) uses the pooled money to invest in various debt instruments.
Each instrument has a face value, coupon rate, and maturity date. The NAV of the fund is updated daily based on the market value of these securities. When the RBI reduces repo rates, older bonds carrying higher coupon rates may witness increased demand, which may increase their market prices and positively impact the fund’s NAV.
Conversely, when interest rates rise, the prices of existing bonds may decline, which may negatively impact debt fund valuations, especially in longer-duration categories. This process is commonly referred to as mark-to-market (MTM) valuation.
How should you invest in debt funds?
A disciplined approach to debt investing generally depends on aligning the investment horizon, credit quality, and risk profile with the investor’s financial goals.
Matching duration
Consider selecting debt fund categories based on the investment horizon. For instance, investors with short-term goals may evaluate liquid funds or ultra short duration funds. Investing in long-duration categories for short-term requirements may expose investors to higher interest rate volatility.
Checking credit quality
Review the AMC’s monthly factsheets to assess the credit quality of the underlying instruments, including ratings such as AAA and AA.
Watching the expense ratio
Debt fund return potential may be affected by expense ratios over time. Comparing the Total Expense Ratio (TER) across schemes may help investors evaluate costs more effectively.
Certain additional factors may also be considered while investing in debt mutual funds:
- Investment horizon: Debt funds are available across different maturity profiles and may be selected based on financial goals and investment horizon.
- Credit quality: Evaluate the quality of securities held within the scheme portfolio before investing.
- Expense ratios and exit loads: Review the expense ratio and applicable exit load structure before investing in any debt fund.
- Consistency: Although past performance does not guarantee future returns, historical performance across different market cycles may help investors evaluate consistency.
- Interest rate risk: Returns from debt funds may be impacted by changes in interest rates, particularly in long-duration debt fund categories.
- Management: The experience of the fund management team and the scheme’s investment process may also be relevant factors for investors to review.
Why should you invest in a debt mutual fund?
Debt mutual funds may offer several features that some investors may consider depending on their financial goals, liquidity requirements, and risk appetite.
Professional fund management
Many retail investors may not have the expertise required to analyse credit quality, interest rate movements, or macroeconomic developments. Debt mutual funds provide access to professional fund managers who manage duration, liquidity, credit exposure, and portfolio allocation in line with the scheme mandate.
Investment options
Some debt mutual fund schemes offer IDCW payout options. However, IDCW payouts are not assured and depend on the availability of distributable surplus.
Relatively lower volatility
Compared to equity-oriented investments, several short-duration and high-credit-quality debt fund categories may exhibit relatively lower volatility. However, debt funds remain subject to market and credit risks.
Liquidity
Many debt funds may offer redemption proceeds within one or two working days, subject to scheme-specific timelines and applicable conditions. Certain liquid funds may also provide instant redemption facilities within prescribed limits.
Benefits of debt funds
Debt mutual funds offer several features that may make them relevant for portfolio diversification and liquidity management.
- Income potential with relatively lower volatility: Debt mutual funds invest in instruments such as corporate bonds, treasury bills, government securities, and money market instruments. Certain categories may exhibit relatively lower volatility compared to equities, although they are not risk-free.
- Relatively higher liquidity: Compared to certain traditional investment products with lock-in requirements, many debt funds may offer relatively higher liquidity.
- Multiple duration options: Debt funds are available across multiple maturity profiles, ranging from overnight funds with one-day maturity exposure to long-duration gilt funds.
- Professional portfolio management: Fund managers manage debt fund portfolios by monitoring duration, liquidity, and credit exposure in line with the scheme mandate.
- Diversification: Debt as an asset class may help diversify a portfolio because it does not always move in line with equity markets.
- Cost efficiency: Investing directly in bonds may involve transaction-related and custody-related costs. Mutual funds may help reduce these costs through pooled investing structures.
Taxation of debt funds in India
For debt mutual fund units purchased on or after April 1, 2023, capital gains are generally taxed at the investor’s applicable income tax slab rate, irrespective of the holding period. The earlier long-term capital gains treatment with indexation benefit is generally not available for such investments.
For units purchased before April 1, 2023, different tax treatment and grandfathering provisions may apply depending on the holding period and applicable regulations. Investors may consider consulting a tax advisor for guidance regarding their individual tax situation.
