New inflation series: Food's weight to fall to 37% from 46%, Pg15

Key Highlights:

• New CPI series with 2024 as the base year will reduce the weight of food and beverage items from 45.86% to 36.75%.
• Housing will become a more prominent component of the CPI basket, potentially increasing overall retail inflation.
• The 2023-24 Household Consumption Expenditure Survey (HCES) reveals a decrease in the proportion of household spending on food in both rural and urban areas.
• The new CPI basket will include 358 items, an increase from the current 299.

Detailed Insights:

• The high weight of food in the CPI has been a concern because fluctuations in food prices significantly impact the headline inflation rate.
• The Reserve Bank of India (RBI) has faced challenges due to the outdated CPI series, which is based on consumption patterns from 2011-12.
• According to Engel's Law, as household income rises, the proportion spent on food decreases, which is reflected in the 2023-24 HCES.
• The RBI's monetary policy is less effective in addressing supply-side issues that affect food prices, limiting its ability to control inflation through interest rate adjustments.
• The flexible inflation targeting (FIT) framework, requiring the RBI to target a CPI inflation rate of 4% within a 2-6% band, is currently under review.
• The first inflation number under the new series will be released on February 12, with data for January.

Key Concepts Involved:

• Consumer Price Index (CPI): A measure that examines the weighted average of prices of a basket of consumer goods and services, such as transportation, food, and medical care.
• Inflation Targeting: A monetary policy strategy where a central bank announces an explicit inflation rate target and commits to adjusting monetary policy to achieve that target.
• Engel's Law: An observation in economics stating that the proportion of a household's income spent on food decreases as income increases.
