The Producer Price Index for the electricity sector during the four-quarter period ending Sept. 22, which marks the end of the second quarter of the current fiscal year, increased by 12% compared with the same period of the year before.
The sector’s PPI (using the Iranian year ending March 2017 as the base year) stood at 192.9 in Q2 (June 22-Sept. 22), indicating an increase of 2.4% compared with the preceding quarter and a rise of 10.9% compared with the same quarter of the year before.
PPI measures price movements from the seller's point of view. Conversely, the consumer price index measures cost changes from the viewpoint of consumers. In other words, this index tracks changes to the cost of production.
The importance of PPI lies in its predictive content for the future pattern of Consumer Price Index. Changes in PPI are usually reflected in CPI within a short period of time.
