RBI IINSS-C Inflation Indexed National Savings Securities-Cumulative


The RBI i.e. Reserve Bank of India has launched the Inflation Indexed National Savings Securities-Cumulative Bond, also know as IINSS-C.
Which offers the investor(s) a return that’s 1.5 per cent more than inflation based on the consumer-price-index.

What is Consumer Price Index?

CPI i.e. Consumer Price Index, is the measure of changes in the price level of a basket of consumer goods and services bought by households. CPI is a numerical estimation calculated using the rates of a sample of representative objects the prices of which are collected from time to time.

Let’s discuss this very easy way.
Bank Fixed Deposits (FD) are the traditional investment vehicle for most Indian households.
According to a recent RBI report approximate 50% of household financial assets in India are in FDs.

One of the major drawbacks of FD is that they fail to beat inflation. Furthermore, interest on FD is also taxable. However, investor(s) have an choose to win the race against the rising prices without taking market risks.
To beat the price rise, invest in the IINSS-C bond.
