The Ministry of Statistics and Programme Implementation has recently changed the time for release of Consumer Price Index and Index of Industrial Production data from 5:30 pm to 4 pm. The change is aimed at giving more time to analyse these data and to align it with the closing time of major financial markets in India.

Consumer Price Index

  • Definition: CPI is a measure of retail inflation based on the prices of goods and services consumed by the country’s population.
  • Publication: It is released by the National Statistical Office (NSO) and includes rural, urban, and combined (national) data at the all-India level.
  • Base year: Currently, CPI is calculated taking 2012 as the base year.
  • Categories: CPI includes various categories such as food and beverages, clothing, housing, fuel and light, and recreation. Currently, CPI is calculated taking into account 299 items.

Index of Industrial Production

  • Definition: IIP is an economic indicator that measures the level of industrial production in an economy, reflecting short-term changes in the production volume of selected industrial products.
  • Publication: It is published by NSO under MoSPI.
  • Base Year: IIP is calculated taking 2011-12 as the base year.
  • Components: There are three main sectors under IIP – mining, manufacturing, and electricity. Apart from this, it is also classified into use-based categories such as basic goods, capital goods, and consumer durables.

Importance of CPI And IIP Data

  • CPI: It is the key inflation indicator that tracks changes in the prices of goods and services purchased by households. It is used for inflation targeting and monitoring price stability.
  • IIP: It is a measure of industrial activity and serves as an indicator of short-term industrial growth. It is used in policy making and assessment of the performance of the economy.

Purpose and concerns of change in timing

  • Due to incidents of data leak in 2013, the data release time was fixed at 5:30 pm to avoid affecting the day’s trading. However, it has now been changed to 4 pm to allow more time for data analysis. However, there are concerns about the potential impact on government bond and forex markets due to this new timing.
  • The ministry says that this change is in line with their commitment to transparency and accessibility and ensures better alignment on the data release day.
