In India, Fixed deposits have long been a favourite investment choice of people, especially senior citizens, as it promise steady returns. It attracts those who are seeking a stable income. But it’s an illusion in the period of inflation. Inflation is the rate at which the general level of prices for goods and services rises, subsequently eroding the purchasing power of money. In simple terms, what money could buy today might not a few years down the line. Fixed deposits are financial instruments offered by banks where you deposit a lump sum amount for a fixed period at a predetermined rate of interest. Consider an investment of Rs 1 crore in a fixed deposit at a 6% annual interest rate and the annual rate of inflation is 5%. By the 10th year your pre inflation return is 1.79 crore, but post inflation it’s just 1.10 crore. The nominal value of investment in fixed deposits may appear to grow, inflation significantly diminishes their real value and purchasing power over time.
