Decoding Debt Mutual Funds (Part III – The Decision Making)

We have learnt about debt mutual funds and its sub-categories, the risks and benefits of debt mutual funds and key events in recent history in our Part 1 and Part 2 of the series ‘Decoding Debt Mutual Funds in India’. Before we move on to the decision-making process, let us debunk a few myths surrounding them.

Which category of debt funds should I select?

The selection of category would depend on your time horizon, intent (whether you just want stable income or capital appreciation as well), liquidity needs and so on. A matrix by HSBC Mutual Fund lays it out well:

Key takeaways:

• As a thumb rule, fund’s duration should be close to your investment period/time horizon or slightly lower. Choosing a longer duration fund than your horizon can lead to you getting caught on the wrong side of the interest rate cycle and making poor returns.

• As the duration/tenure increases, the sensitivity to interest rate also increases, implying a greater probability of capital appreciation (but greater risk as well).

Which Fund Should I select within the category?

Within each category, an investor should look at the following things, in addition to the overall returns, when selecting a fund:

• YTM - compare the YTM to the category average. Beware that, if a fund's YTM is significantly higher than its peers (e.g., 8.5% vs 7.2%), it is likely taking higher credit risk.

• Credit Risk - Minimising credit risk is key to protecting your capital. Hence for safety purposes, stick to funds with 90%+ in AAA, A1+ and SOV (Sovereign) papers.

• AUM - AUM does matter in certain sub-categories like ‘Liquid’ or ‘Corporate Bond’ since larger AUM usually implies better negotiating power and liquidity buffers.

• Portfolio Composition - One needs to also check the ‘Top 10’ holdings of the scheme to evaluate concentration risk. E.g., if 6-8% of the portfolio is invested in a single company or group could signal a potential concentration risk.

• Potential Risk Class (PRC Matrix) - Every debt mutual fund is mandated to present a PRC matrix for its scheme in the fact sheet. Below is a sample PRC indicating various sub-categories mapped under the matrix.

Conclusion: Debt mutual funds in India represent a sophisticated alternative to traditional fixed deposits, offering superior liquidity, tax deferral in some cases and the potential for capital appreciation, but they demand a fundamental shift in mindset from "guaranteed safety" to "managed risk."

Unlike the static nature of FDs, these funds operate on a dynamic spectrum where returns are driven by the interplay of interest rate cycles and credit quality. While they serve as excellent tools for portfolio stability and income generation, historical precedents like the IL&FS crisis and the 2020 winding-up events underscore that they are not immune to credit defaults or liquidity freezes.

Therefore, successful investing in this asset class requires looking beyond past returns and strictly aligning the fund’s Modified Duration and PRC with your personal investment horizon, ensuring you are compensated adequately for the risks you choose to take.
