Interest Rate Risk

The changes in interest rate have a bearing on the welfare of investors. As the interest rate goes up, the market price of existing fixed income securities falls, and vice versa.

This happens because the buyer of a fixed income security would not buy it at its par value or face value if its fixed interest rate is lower than the prevailing interest rate on a similar security.

For example, a debenture that has a face value of MR 100 and a fixed rate of 12% will sell at a discount if the interest rate moves up from, say, 1% to 14%.

While the changes in interest rate have a direct bearing on the prices of fixed income securities, they affect equity prices too, albeit somewhat indirectly.

The changes in the relative yields of debentures and equity shares influence equity prices.
