The GPI is the weighted arithmetic mean of three price indexes, the PPI, the CPI, and the NCCI. It reveals the sources of inflationary pressure and the evolution of the prices of the most relevant products and services for the producer, the consumer, and the construction industry.
The GPI was conceived at the end of the 1940s as a comprehensive measure of changes in prices in Brazil. An index is understood as comprehensive when it encompasses not only different activities, but also distinctive stages in the production process. Its construction enabled the GPI to be used as a deflator of the business activity index, thereby resulting in a monthly indicator of the level of economic activity. The weights of each component index correspond to shares of gross domestic expenditure, calculated based on the National Accounts.
