Investment banking services price index (IBSPI) measures the change in price of investment banking services. Annual data are available from 2010. The table presents data for the most recent reference period and the last four periods. Data is available in a Fisher, Laspeyres or Paasche index. The base period for the index is 2017=100.

Monthly raw data are processed at the most detailed level in order to calculate elementary unit-values defined by trade value/quantity. These unit-values are divided by the average unit-value of the previous year to obtain elementary unit-value indices, from which outliers are detected and removed. Elementary unit-value indices are then aggregated over countries and commodities, by using the Laspeyres, Paasche and Fisher formulae. Finally, the Fisher unit-value indices are chained back to the reference year (2015 = 100) and are used to approximate the import and export price movements.
