Reviews to the calculation of the Producer Price Index

The calculation of the Producer Price Index will be reviewed starting from the Index for January 2019 so that the indices become annual chain-linked indices.

In practice, the shift to the chain-linked index method means that the weight structure of the Producer Price Index will in future be updated every year. The new weight structure will take effect starting from the Index for January of each year. In addition to the weight structure, product categories and the enterprise sample can also be updated annually, if needed. The base year of the Index remains unchanged (2015=100).

In future, the index calculation will be made so that each index series is chained forward with changes in the Index calculated according to the new weight structure. A more detailed description of the calculation method is available in the updated Producer Price Index for Manufactured Products and Producer Price Indices for Services 2015=100 Handbook for Users to be published in spring.

These changes improve the quality of the Index, because with their help, structural changes in production, exports and imports can be taken into account faster in future.
