ISI
n. countablen. a way to measure how much prices change for things that people buy. It is often used in countries like India to track how expensive life is getting.
n. a statistical measure that tracks changes in the price level of a weighted average market basket of consumer goods and services. Typically used in specific economic jurisdictions, such as India, to monitor inflation and adjust wages or pensions.
The government monitors the ISI to understand inflation trends.
Economists noted that the recent rise in the ISI was driven primarily by a sharp increase in food and fuel costs.
While the ISI provides a snapshot of consumer price volatility, critics argue that the current weighting of the basket fails to account for the shifting consumption patterns of the urban middle class.
Often used with the definite article ('the ISI') when referring to the specific index of a country.
