CPI defines the change in retail prices for a basket of goods and services. CPI is considered more reliable if it does not take into account food and energy industries. When calculating this index prices for imported goods and services are taken into account. Consumer Price Index is the main indicator of inflation in the country.
This index should be analyzed together with PPI (Producer Price Index). If the economy develops in normal conditions, the increase in CPI and PPI can lead to an increase in key interest rates in the country. This, in turn, leads to growth of the dollar because of the increasing attractiveness of investing in currencies with higher interest rates.
