Producer Price Index

The Producer Price Index (PPI) is a monthly survey that measures the price changes of goods bought and sold by UK manufacturers and provides a key measure of inflation, alongside other indicators such as the Retail Prices Index (RPI), Consumer Prices Index (CPI) and Services Producer Prices Index (SPPI). This statistical bulletin contains a comprehensive selection of data on input and output index series. It contains producer price indices of materials and fuels purchased and output of manufacturing industry by broad sector.

The output price indices measure change in the prices of goods produced by UK manufacturers (these are often called 'factory gate prices').

The input price indices measure change in the prices of materials and fuels bought by UK manufacturers for processing. These are not limited to just those materials used in the final product, but also include what is required by the company in its normal day to day running.

Imported Price Indices (IPIs) are a series of economic indicators that measure change in the prices of goods and raw materials imported into the UK. IPIs are a key component of input price indices.

Exported Price Indices (EPIs) are a series of economic indicators that measure change in the prices of goods manufactured in the UK but destined for export markets.

Output prices: summary of statistics

The overall output price index rose 2.2 per cent in the year to August 2012, compared with a rise of 1.8 per cent in the year to July 2012. The output price index rose 0.5 per cent between July and August, compared with a rise of 0.1 per cent between June and July. The main contributions to the rise in the price index were from petroleum products, chemical & pharmaceutical products and tobacco & alcohol products.

Petroleum product prices rose 3.2 per cent between July and August and rose 1.5 per cent in the year to August. The increase of 3.2 per cent between July and August is the largest monthly rise since March 2011, when the index rose 4.4 per cent. The monthly rise was mainly due to a 3.1 per cent increase in the price of diesel & gas oil and a 2.8 per cent increase in the price of unleaded petrol.

Chemical & pharmaceutical product prices rose 0.9 per cent between July and August but fell 2.1 per cent in the year to August. The monthly rise was mainly due to a 6.7 per cent increase in the price of other organic basic chemicals and a 2.4 per cent increase in the price of plastics in primary forms. 

Tobacco & alcohol product prices rose 0.3 per cent between July and August and rose 8.6 per cent in the year to August. This is the highest annual rate since December 2008, when the index rose by 8.9 per cent. The monthly rise was due to a price increase of 0.5 per cent and 0.2 per cent for tobacco products and alcoholic beverages respectively.

Output price index excluding food, beverages, tobacco & petroleum

The output price index for manufactured products excluding food, beverages, tobacco & petroleum rose 1.2 per cent in the year to August, unchanged from last month. The last time the annual rate was lower was in December 2005, when the index rose 1.1 per cent. This index is not affected by changes in excise duty.

Input prices: summary of statistics

The overall input index rose 1.4 per cent in the year to August 2012, compared with a fall of 2.4 per cent in the year to July 2012. The input index for all manufacturing rose 2.0 per cent between July and August, compared with a rise of 0.4 per cent between June and July. The main contribution to the rise in the price index was crude oil. This rise was offset by price falls in home produced food, imported metals and fuels (incl CCL).

Crude oil prices rose 9.3 per cent between July and August and rose 4.0 per cent in the year to August. The monthly rise of 9.3 per cent is the highest monthly increase since March 2011, when the index rose 9.9 per cent.

Home produced food prices fell 1.9 per cent between July and August but rose by 13.8 per cent in the year to August. The monthly fall of 1.9 per cent is the highest monthly decrease since July 2011, when the index fell 4.2 per cent and is due to widespread decreases across a broad range of products, most notably a 11.9 per cent decrease in the price of home produced fresh vegetables and a 2.4 per cent decrease in the price of home produced potatoes. 

Imported metal prices fell 1.9 per cent between July and August and fell 13.8 per cent in the year to August. This is the lowest annual rate since records began (January 1997). The monthly fall of 1.9 per cent was due to widespread decreases across a broad range of  products, most notably a 4.6 per cent fall in the price of non EU imports of basic iron & steel & of ferro-alloys, a 1.9 per cent fall in the price of EU imports of copper and a 1.2 per cent fall in the price of EU imports of aluminium.

Fuel (incl CCL) prices fell 0.6 per cent between July and August but rose 5.0 per cent in the year to August. This is the lowest annual rate since March 2011, when the index rose 4.9 per cent. The monthly fall of 0.6 per cent was mainly due to a  decrease of 2.2 per cent in the price of gas.

Input price index excluding the food, beverages, tobacco & petroleum industries

The index for materials and fuels purchased by manufacturing industry excluding the food, beverages, tobacco & petroleum industries rose 1.0 per cent in seasonally adjusted terms between July and August. The unadjusted index fell 0.4 per cent in the year to August, compared with a fall of 1.5 per cent in the year to July.

Revisions

Revisions (Tables 8R and 9R)

For this bulletin reference tables 8R and 9R (223 Kb Excel sheet) highlight revisions to movements in price indices previously published in last month’s statistical bulletin. These are mainly caused by changes to the most recent estimates, as more price quotes are received, and revisions to seasonal adjustment factors, which are re-estimated every month. The headline figures for both input and output, for June 2012, have unusually high downward revisions. These revisions were mainly caused by quality adjustments due to late data.

    A Quality and Methodology Information (QMI) (95.6 Kb Pdf) paper for the PPI describes in detail the intended uses of the statistics presented in this publication, their general quality and the methods used to produce them.

  5. Producer Price Index and Services Producer Prices: implementation of SIC 2007

    Producer Prices has implemented the change to the Standard Industrial Classification 2007 (SIC 2007). The most significant change to PPI output prices involves the reclassification of ‘recovered secondary raw materials’ and ‘publishing’. These are no longer classified in the manufacturing sector, but are classified under services. In addition to this, a new SIC division, ‘repair, installation and maintenance of machinery and equipment’ has been created. Under SIC 2003 these activities were classified within the output of manufacturing, but as part of the specific industries where this activity took place.

    Fundamental changes have been made to the classification of the PPI Trade surveys, Import Price indices (IPI) and Export Price Indices (EPI). As part of the reclassification project the classification of these trade surveys have become compliant with Eurostat’s Short Term Statistics Regulation. The collection of IPI and EPI will now be on an SIC basis, a switch from the Standard International Trade Classification (SITC) and Combined Nomenclature (CN) previously used. PPI input prices are heavily dependent on IPI.

    For further information on the changes and impact of the SIC 2007 on prices please see the Economic and Labour Market Review for December 2010 (84.1 Kb Pdf) .

  6. Relevance to users

    Index numbers shown in the main text of this bulletin are on a net sector basis. The index for any sector relates only to transactions between that sector and other sectors, sales and purchases within sectors are excluded. However, the more detailed figures shown in reference tables 4 and 6 (223 Kb Excel sheet) are on a gross basis; that is, intra industry sales and purchases are included in each of these indices.

    Indices relate to average prices for a month. The full effect of a price change occurring part way through any month will only be reflected in the following month’s index.

    All index numbers exclude VAT. Excise duty (on cigarettes, manufactured tobacco, alcoholic liquor and petroleum products) are included, except where labelled otherwise. Since PPIs exclude VAT, they are not affected by the increase in the standard rate of VAT to 20 per cent from 4 January 2011.

    The detailed input indices of prices of materials and fuels purchased by industry (reference table 6) (223 Kb Excel sheet) do not include the climate change levy (CCL). This is because each industry can, in practice, pay its own rate for the various forms of energy, depending on the various negotiated discounts and exemptions that apply.

  7. Common pitfalls in interpreting series

    Expectations of accuracy and reliability in sample surveys are often too high. Revisions and sampling variability are inevitable consequences of the trade off between timeliness, accuracy and the burden on respondents. Details of sampling variability are included elsewhere in this bulletin.

    Very few statistical revisions arise as a result of ‘errors’ in the popular sense of the word. All estimates, by definition, are subject to statistical ‘error’ but, in this context, the word refers to the uncertainty in any process or calculation that uses sampling, estimation or modelling. Most revisions reflect either the adoption of new statistical techniques or the incorporation of new information which allows the statistical error of previous estimates to be reduced. Only rarely are there avoidable ‘errors’ such as human or system failures, and such mistakes are made quite clear when they are discovered and corrected.

  8. Accuracy

    Figures for the latest two months are provisional and the latest five months are subject to revisions in light of (a) late and revised respondent data and (b), for the seasonally adjusted series, revisions to seasonal adjustment factors which are re-estimated every month. A routine seasonal adjustment review is normally conducted in the autumn annually. There are no planned methodological changes in the next 12 months.

    The United Kingdom Statistics Authority has designated these statistics as National Statistics, in accordance with the Statistics and Registration Service Act 2007 and signifying compliance with the Code of Practice for Official Statistics.

    Designation can be broadly interpreted to mean that the statistics:

    • meet identified user needs;
    • are well explained and readily accessible;
    • are produced according to sound methods; and
    • are managed impartially and objectively in the public interest.

    Once statistics have been designated as National Statistics it is a statutory requirement that the Code of Practice shall continue to be observed.
