The PPI indicator measures change in the selling prices received by domestic producers for their output. The target set for goods and services included in the PPI is the entire marketed output of US producers
The set includes both goods and services purchased by producers as input to their operations. The price collected for the PPI is the revenue received by its producer, and excludes sales and excise taxes as they do not represent revenue to the producer. It is important to mention that goods and services also purchased by consumers directly from the service producer or indirectly from a retailer are included in this economical indicator.
The CPI, in contrast to the PPI, includes sales, excise taxes and imports, because they are necessary expenditures by the consumer of the item. The main difference between PPI and CPI is that the former is used to adjust real growth in output, while the latter is used to adjust income and expenditure streams for changes in the cost of living.
PPI is a similar economic indicator in terms of interpretation as the CPI, with the main purpose of measuring inflation. Generally, a rise in inflation reflects a decline in the purchase power of a country’s currency, which may lead to depreciation of that currency.
On the other hand, a rise in a country’s inflation may also lead to the rise of the nominal interest rates, which may attract the interest of investors for that country’s currency thus, leading to appreciation.
