India to use PPI for GDP deflation
The Indian government is planning to use the Producer Price Index (PPI) instead of the Wholesale Price Index (WPI) to adjust GDP figures for inflation.
This change is expected to make India's GDP calculations more accurate and align them with international standards.
The new method will be used starting from the April-June quarter of 2026-27.
Economists believe this change won't significantly affect GDP growth rates in the short term, but it will make the size of real GDP more accurate.
The government has also updated the base year for GDP calculations to 2022-23 from 2011-12, which has led to changes in how inflation adjustments are made.
The WPI will be phased out in favor of the PPI, and the Consumer Price Index (CPI) will continue to be used for more detailed adjustments.
India will use the Producer Price Index (PPI) for GDP deflation starting April-June 2026-27.
The change aims to align national accounts data with international standards.
Economists expect minimal impact on GDP growth rates in the short term.
The base year for GDP series has been updated to 2022-23 from 2011-12.
Double deflation will be used in sectors like manufacturing and agriculture for more accurate measurements.
