Unveiling the role of credit ratings in debt mutual funds

Credit ratings play an important role in debt mutual funds. They indicate the creditworthiness and default risk of companies and financial instruments like bonds, debentures and commercial papers that debt funds invest in. Higher credit ratings signify higher safety and lower risk, while lower ratings imply higher risk of default. Read on to find out more.

Understand credit rating agencies

Credit rating agencies like CRISIL, ICRA, CARE and Brickworks analyze and rate the creditworthiness of companies and their financial instruments based on factors such as financial performance, management quality, competitive position and cash flows. They assign ratings ranging from ‘AAA’ (highest safety) to ‘D’ (default). Ratings of ‘A’ and above are considered investment-grade. Debt mutual funds invest in instruments rated investment-grade and higher.

Impact of ratings on debt fund portfolios

The rating assigned to a company and its papers like debentures or commercial papers impacts their inclusion in a debt fund’s portfolio. Funds usually invest a majority in highly rated instruments to ensure high safety and liquidity. For example, liquid and money market funds invest in ‘A1+’ and ‘AAA’ rated papers for high safety. As ratings go down, risks rise. So, lower-rated papers may find a place only in small portions of a portfolio, or in funds targeting high returns with higher risk like corporate bond funds.

Monitor ratings regularly for allocation adjustments

Debt fund managers regularly monitor ratings assigned to companies they invest in. If ratings are downgraded, especially below investment-grade, they may sell papers to comply with the fund’s investment mandate. For example, if papers of a company in a liquid fund’s portfolio are downgraded below ‘A1’ or ‘AAA’, the manager will sell them. Similarly, if ratings improve, managers may allocate more to highly rated papers. Continuous monitoring of ratings helps optimize fund portfolio risk and return.

Study the impact of past downgrades 

It is important for investors to study how a debt fund has dealt with past credit downgrades in their portfolio. Check if the fund manager took prompt action to exit downgraded papers to contain risks, especially for more conservative funds. For higher risk funds, see that additional risks from downgrades were managed prudently without significant impact on returns. The fund’s policy on investing in lower-rated papers also provides guidance on their appetite for credit risk that you must be comfortable with before investing.

Look beyond just ratings for a holistic view

While important, credit ratings are not the sole factor to consider when evaluating top mutual funds. Also, assess the overall portfolio quality based on the type of issuers, proportion of higher and lower-rated papers, concentration levels, etc. The fund manager’s track record and experience in navigating difficult market conditions also matter. Study the performance of the fund during periods when there were large-scale downgrades to see how risks were managed. Check if the returns adequately compensate for the risks in the fund before choosing one aligned to your needs.

Credit ratings provide a crucial reference point for debt fund managers to construct high-quality investment portfolios and for investors to choose funds matching their risk preferences. However, they must be interpreted along with other factors like portfolio attributes, fund policies and manager skills to make an informed choice. Regular monitoring and review of how funds handle any changes in ratings help ensure your debt fund investments remain stable, safe and profitable over the long run.
