If you know what debt funds are, then let us go a step further and tell you how is it that they generate returns. The choice of the best debt funds for investment also, just like any other mutual fund, depends upon your investment
objective and risk appetite. The returns gathered by debt mutual funds come from two sources- the interest accrued by the underlying securities and the capital gains garnered.
Now, though it is widely said that debt mutual funds come with very low risk, it is practically not true for all the funds. The two major types of risks associated with investing in debt funds are interest rate risk and
credit risk. The former is related to the fluctuation in the bond price, with fluctuation in the interest rates of the market. The longer the duration of a debt fund, the more it is exposed to interest rate risk. The other risk
is credit risk, which is basically saying that the party you are lending your money to through the debt security, may not be able to repay the money back to you.
The interest rates are inversely proportional to the bond’s price. If the interest rate falls, the bond price increases. Let us understand this with an example. If you purchase a bond of face value Rs 1000 at 8% interest
and maturity of 5 years, the interest on your bond will be 8% of Rs 1000, i.e. Rs 80 per year. Now, when the market interest rate increases, the new bonds will be more lucrative than yours, and hence, your bond will trade at a
lower price than the original face value. Similarly, the bond price goes up in the case of a decrease in interest rate. Now, by varying the duration of the securities held in a debt fund, the fund managers may aim to gain an advantage
from the interest rate changes. Now, different debt funds types adopt different investment strategies to achieve their objectives, and thus, these risks come in different degrees with every type of fund. Let us see how.
