The service producer price index (SPPI) is defined as an output price index for the service production of resident producers. It has two main goals. The first is to be a short-term indicator of the business cycle. In this respect SPPI has to reflect changes in prices as fast as possible. The second is to be a suitable deflator for value developments. SPPI should thus represent all output as defined in National Accounts and follow, as closely as possible, the accrual principle in recording prices. Data are not seasonally adjusted.
