A decision from our recent review of scope and purpose of the PPI was to start publishing as many commodity indexes as possible, subject to confidentiality and fit-for-purpose quality. Until the June 2015 quarter we published about 20 commodities.
From the September 2015 quarter, we are publishing additional commodity indexes in the Business Price Indexes information releases. We are publishing more than 100 output and more than 100 input indexes. A selection of commodities is available in the PPI tables and the remainder are in Infoshare.
See the downloadable Excel file under 'Available files' on this page for a list of the commodity indexes we are publishing, and a concordance from the old to the new tables. We reviewed all our commodities.
About the commodities
Most commodities are at the level we publish for the PPI industry-by-commodity weight tables. However, we are also publishing selected lower-level commodities if they meet our confidentiality and fit-for-purpose quality standards.
The commodities published are aggregations of the National Accounts 2006 Commodity Classification (NA06CC) used in our national accounts supply and use reconciliation. Some of the commodities are aggregated for confidentiality reasons.
We have included a commodity concordance table in the Excel file to show how the NA06CC aligns to the aggregated commodity categories.
We are publishing both output and input commodities. The output commodities are used in compiling the output PPI, and the input commodities for compiling the input PPI. The main differences between the two types are:
Output commodities: domestic sale prices (to households, businesses); export prices.
Input commodities: domestic purchase prices (from businesses); import prices.
Output commodities should contain prices measured at basic/producer’s prices (the price the producer receives for goods), while input commodities should be priced in purchaser’s prices (the price a producer pays for goods). In practice, we mainly collect prices in basic/producer’s prices – because the additional supplier load to get all prices in two pricing points outweighs the benefit.
