Introduction

Bond mutual funds are a standard investment option for Indian investors looking for consistent returns with moderate risk. The most important calculation you will need to do to analyse bond mutual funds is Yield to Maturity (YTM), which provides the expected return on a fixed-income investment. Anyone wanting to invest in India's rapidly evolving debt market must better understand YTM for a solid investment option. This article will provide an overview of YTM, how it applies to mutual fund returns, and how it is useful.

What is Yield to Maturity?

Yield to Maturity (YTM) gauges the total annualised return an investor can expect to earn on a bond if they hold it until maturity. In bond mutual funds, YTM is calculated from the weighted average yield of all the bonds in the portfolio based on the bond's market price, intrinsic value, coupon rate, and time to maturity. In calculating YTM, it is assumed that interest payments are reinvested at the same YTM return and that the bond was held until maturity.

Think of YT as a measurement of a fund's earning potential. For example, bond mutual funds with a YTM of 7% mean that an investor could expect approximately 7% return annually, given all things stay the same. Since most debt funds in India are issued in G-Sec (government security) and corporate bonds, YTM is useful for tracking performance.

Why YTM Matters

YTM has a major impact on bond mutual fund returns and provides Indian investors an opportunity for several value comparisons:

Return Comparison: It allows an investor to compare funds. For example, a corporate bond fund with an 8% YTM could be more attractive than a gilt fund with 6%, assuming a fair comparison of risk.

Income Estimation: Since YTM measures prospective dividends or interest payments, it indicates how much an investor might expect to receive every month or year. This will be important for retirees and/or individuals relying on monthly or yearly income. Higher YTMS often translate to bolstered actual distributions.

Portfolio Assessment and Future Refinements: YTM is useful in gauging, in real time, the mix of bonds in the fund, which can help understand the mix of credit and maturities. This is useful to understand a taxable bond fund that is mixed in terms of the type of bond, as longer-term bond funds can have higher YTMS and more daily fluctuations.

In the Indian economy, where the bond market is affected by RBI actions and inflation, YTM enables future bond fund performance trends to be gleaned in an ever-changing economic environment.

How YTM Affects Returns

Interest Rate Motion: There is an inverse relationship between YTM and bond price. When the RBI increases interest rates, as in the case of the RBI's action in 2022-2023, as prices decrease, YTM also decreases. Conversely, when rates fall, bond price increases, and YTM increases. Investors should follow developments on the RBI's repo rate, as it is the most effective indicator of likely trends in YTM in debt funds.

Fund Duration: Long-duration funds, such as gilt funds, will often have a higher YTM because of interest rate risk, whereas short-duration funds, such as liquid funds, will have a lower YTM, but it is reasonably stable.

Credit Quality: Funds with lower-rated bonds (AA rated) will offer higher levels of YTM than higher-rated bonds to account for the risk of default. A YTM fund of 9% will accrue more risk than a fund rated AAA at 7%.

For example, Fund X (corporate bonds; 7.5% YTM) may eventually outperform Fund Y (G-Secs; 6.8% YTM) but will have credit risks. Therefore, you can see how the YTM ultimately provides a balance to measure the trade-offs.

Limitations of YTM

Maturity Assumption: YTM is based on the idea that these bonds are held to maturity, which seems unlikely if managers are selling bonds early to gain or cut losses.

Reinvestment Risk: It assumes that the coupons are reinvested at the same YTM, which could be difficult if rates fall. Suddenly, coupons from a fund with a 7% YTM reinvested in bonds with a 5% yield will lessen your return.

Credit and Call Risk: The default of the company lending money (credit risk) or the fact that you could have to redeem (call) your bonds early will mess up your YTM calculations. This is especially true in the Indian corporate bond market.

Market Volatility: When the economic environment changes, your bond prices can fluctuate drastically, like during inflation, which impacts short-term price returns.

Taxation in India

Returns from debt funds based on YTM will get taxed per the investor's slab rate (from April 2025), with no indexation. High-YTM funds with active trading may distribute taxable amounts, thus impacting net returns. Taxes should be considered in your evaluations of YTM.

Conclusion

Yield to Maturity is a crucial metric for Indian investors regarding bond mutual funds, as it shows their potential return on investment and helps identify risks in the portfolio. Investors need to understand YTM as a measure, its limitations, and how it reacts to certain market factors while negotiating their way around the debt market in India. Whether you are looking for income or want to balance risk, YTM can help make more informed decisions. Evaluate the risk tolerance you are comfortable with, and get advice on how YTM fits your desired goals.
