The monthly producer inflation decreased from 1.6% in the month ending March 19 to -0.8% in the month ending April 19.
“Year-on-year producer inflation reached 20.9% for the month under review, indicating a 2.9 percentage point decline compared with that of the month before,” Hemmati was quoted as saying by the CBI website.
"Given the forward-looking nature of PPI, a decline in Consumer Price Index and inflationary expectations would be down the line," he added.
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 CPI measures changes in the price level of a basket of consumer goods and services purchased by households.
In other words, PPI is an index of prices measured at the wholesale, or producer level. It shows trends within the wholesale markets (as it was once called the Wholesale Price Index), production and manufacturing industries, as well as commodities markets, from the perspective of the seller.
According to Investopedia, PPI can serve multiple roles in improving investment-making decisions, because it can serve as a leading indicator of CPI.
When producers face input inflation, those rising costs are passed along to the retailers and eventually to the consumer.
PPI presents the inflation picture from a different perspective than CPI. Although changes in consumer prices are important for consumers, tracking PPI allows one to determine the cause of changes in CPI.
If, for example, CPI increases at a much faster rate than PPI, such a situation could indicate that factors other than inflation may be causing retailers to increase their prices.
However, if CPI and PPI increase in tandem, retailers may be simply attempting to maintain their operating margins.
All in all, a decrease in PPI is one of the signs of a probable slowdown in CPI in future months. Almost a perfect correlation exists between CPI and PPI.
