A basket of goods is a standardised collection of specific consumer products and services whose prices are tracked over time to measure inflation and changes in the cost of living. The composition of the basket is designed to reflect the typical spending patterns of the target population — with each item weighted according to its proportional share of average household expenditure. In India, the Consumer Price Index (CPI) is based on a basket of goods and services that covers food and beverages (the largest weight at approximately 45%), fuel and lighting, clothing and footwear, housing, health, education, and miscellaneous services. The basket's composition and weights are periodically revised by the Ministry of Statistics and Programme Implementation (MoSPI) to reflect evolving consumption patterns. For Indian equity investors and macro analysts, CPI inflation data derived from the basket of goods is one of the most important economic indicators — it directly influences RBI monetary policy decisions on interest rates, which in turn affect bond yields, credit costs for companies, consumer spending, and ultimately corporate earnings and equity valuations. A basket of goods heavily weighted toward food items makes India's CPI particularly sensitive to agricultural output and monsoon conditions.
