The Producer Price Index in the 12-month period ending September 22, which marks the end of summer, increased 6.6% compared to the same period of last year. Mehr News Agency also cited the Statistical Center of Iran’s latest report as saying on Monday that the PPI index indicates a 0.6% decrease compared to last summer, the report said. 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. PPI gauges the price fluctuations of goods and services for the producer whereas Consumer Price Index measures changes in the price level of a basket of consumer goods and services. According to SCI’s latest report on CPI inflation, the goods and services Consumer Price Index for urban areas increased 13.3% in the 12-month period ending October 22, compared to the similar period of last year.
