Statistical bulletin: Producer Price Inflation, November 2015 This product is designated as National Statistics

Released: 15 December 2015 Download PDF

Main points

  • The price of goods bought and sold by UK manufacturers, as estimated by the producer price index, continued to fall in the year to November 2015. Crude oil continued to drive down input prices, feeding through to a drop in output prices of petroleum products.
  • Factory gate prices (output prices) for goods produced by UK manufacturers fell 1.5% in the year to November 2015, compared with a fall of 1.4% in the year to October 2015.
  • Core factory gate prices, which exclude the more volatile food, beverage, tobacco and petroleum products, fell 0.1% in the year to November 2015, compared with a rise of 0.3% in the year to October 2015.
  • The overall price of materials and fuels bought by UK manufacturers for processing (total input prices) fell 13.1% in the year to November 2015, from a fall of 12.3% in the year to October 2015.
  • Core input prices, which exclude the more volatile food, beverage, tobacco and petroleum products fell 8.3% in the year to November 2015, compared with a fall of 6.7% in the year to October 2015.

What is the Producer Price Index (PPI)?

The Producer Price Index (PPI) is a monthly survey that measures the price changes of goods bought and sold by UK manufacturers and provides an important measure of inflation, alongside other indicators such as the Consumer Price Index (CPI) and Services Producer Price Index (SPPI). This statistical bulletin contains a comprehensive selection of data on input and output index series and also 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.

The factory gate price (the output price) is the price of goods sold by UK manufacturers and is the actual cost of manufacturing goods before any additional charges are added, which would give a profit. It includes costs such as labour, raw materials and energy, as well as interest on loans, site or building maintenance, or rent.

Core factory gate inflation excludes price movements from food, beverage, petroleum, and tobacco and alcohol products, which tend to have volatile price movements. It should give a better indication of the underlying output inflation rates.

The input price is the cost of goods bought by UK manufacturers for the use in manufacturing, such as the actual cost of materials and fuels bought for processing.

Core input inflation strips out purchases from the volatile food, beverage, tobacco and petroleum industries to give an indication of the underlying input inflation pressures facing the UK manufacturing sector.

Output prices: summary

Factory gate inflation fell 1.5% in the year to November 2015, compared with a fall of 1.4% last month.

The rate of both total output and core inflation has generally been falling since autumn 2011, when output inflation reached its post-economic downturn high of 5.3% in September 2011. During this period, core factory gate inflation has tended to run at a lower rate and show a smaller degree of volatility than total output inflation. However, since January 2014, core output price inflation has been running at a slightly higher rate than total output inflation: a result of the downward pressures from petroleum, which is excluded from the core measure of inflation (Figure A).

Looking at the latest estimates (Table A), movements in factory gate prices over the 12 months to November 2015 were as follows:

  • factory gate prices fell 1.5%, compared with a fall of 1.4% in the year to October 2015

  • core factory gate prices fell 0.1%, compared with an increase of 0.3% in the year to October 2015

  • factory gate inflation excluding excise duty fell 1.2%, unchanged from the year to October 2015

Between October and November 2015:

  • factory gate prices decreased 0.2%, compared with a fall of 0.1% last month

  • core factory gate prices decreased 0.2%, compared with a fall of 0.1% last month

Output prices: detailed commentary

Factory gate prices fell 1.5% in the year to November 2015, compared with a fall of 1.4% in the year to October 2015. Prior to July 2014, there had been no fall in the annual rate since October 2009, when it fell 0.1%. The main contribution to the annual rate for November 2015 came from petroleum products. Smaller falls in the prices of food products, and chemicals and pharmaceuticals also contributed towards the fall in the output of manufactured product prices (Figure B).

The monthly price index between October and November 2015 saw a fall of 0.2%, compared with a fall of 0.1% between September and October 2015. The majority of product groups showed decreases; downward movements for petroleum, clothing, textiles and leather, and food products provided the main downward contributions to the monthly rate (Figure C).

Petroleum product prices fell 16.5% in the year to November 2015, up from a fall of 17.8% in the year to October 2015. The largest decrease seen in this index was in July 2009, when it fell by 21.3%. The main contributions to the fall in the latest annual rate came from diesel and gas oil, motor spirit, and aviation turbine fuel.

Food products fell 1.5% in the year to November 2015, up from a fall of 1.7% in the year to October 2015. The monthly index for food products fell 0.2% between October and November 2015, up from a fall of 0.1% between September and October 2015. The main contribution to the decrease in the annual index came from dairy products, falling by 6.1% in the year to October 2015. The main contribution to the decrease in the monthly indices was from preserved meat and meat products which fell 0.4% between October and November 2015.

Chemical and pharmaceutical products fell 1.9% in the year to November 2015, down from a decrease of 1.7% in the year to October 2015, due to a fall in the price of chemicals and chemical products.

Clothing, textiles and leather product prices decreased 0.4% between October and November 2015, down from a fall of 0.2% between September and October 2015. A fall in the price of wearing apparel was the only contributor towards this decrease.

Core factory gate inflation

Core factory gate prices, which exclude the more volatile food, beverage, tobacco and petroleum product prices, giving a measure of the underlying factory gate inflation, fell 0.1% in the year to November 2015, compared with a rise of 0.3% in the year to October 2015. This is the first fall seen in this index since the year to November 2009. Falls in chemicals and pharmaceuticals, and transport equipment was partially offset by an increase in prices for other manufacturing products in the annual index.

The monthly index showed a fall of 0.2% between October and November 2015, compared with a decrease of 0.1% between September and October 2015. Clothing, textiles and leather, transport equipment, and chemicals and pharmaceuticals provided the largest contributions to the fall in the index, slightly offset by an increase in other manufactured products.

Output producer price index contribution to change in rate

The annual percentage rate for the output PPI in November 2015 fell 1.5%, compared with a fall of 1.4% last month, resulting in a decrease in the annual rate of 0.1 percentage points. The main contribution to the decrease came from clothing, textiles and leather, offset by petroleum products (Figure D).

Output PPI indices by grouping

Figure E shows the year on year growth in output PPI by grouping for the latest 2 months and the range of the price changes that have been seen in these sections since January 2015. It can be seen that the majority of output PPI indices have experienced little variance in inflation during 2015. Petroleum shows the biggest decrease, ranging from falls of 20.7% in January 2015 to 14.2% in May 2015. Tobacco and alcohol shows the biggest increase, ranging from rises of 3.6% in January 2015 to 0.4% in September 2015.

Input prices: summary

The price inflation of materials and fuels purchased by UK manufacturing industry, as measured by input prices, has been falling since November 2013 (Figure F). The movements in the index since February 2014 have shown input prices decreasing rapidly. The largest fall was seen in August 2015 (14.6%) with input prices currently falling by 13.1%. The core measure of inflation has also decreased through this period, but at a significantly slower rate, currently 8.3%.

Looking at the latest data (Table D), the main movements in the year to November 2015 were as follows: 

  • the total input price index fell 13.1%, compared with a fall of 12.3% in the year to October 2015 

  • the core input price index saw a fall of 8.3%, compared with a fall of 6.7% in the year to October 2015

  • the price of imported materials as a whole (including crude oil) fell 13.5%, compared to a decrease of 12.5% in the year to October 2015 ( Reference table 7 (229 Kb Excel sheet) )

Between October and November 2015:

  • the total input price index fell 1.6%, compared with no movement last month (Table D)

  • in seasonally adjusted terms (see Table D), the input price index for the manufacturing industry excluding the food, beverage, tobacco and petroleum industries fell 1.3%, unchanged from last month

Input prices: detailed commentary

The overall input index for all manufacturing, which measures changes in the price of materials and fuels purchased by manufacturers, fell 13.1% in the year to November 2015, compared with a fall of 12.3% in the year to October 2015. The main downward contributions to the index came from crude oil with a much smaller, but notable, downward contribution from imported metals.

Imported metal prices fell 19.7%, this is the largest decrease since records began in 1997. The main contribution came from imported products used in the manufacture of other basic metals and casting, which fell 20.2%. The price of the majority of metals measured in the PPI, have fallen significantly due to the recent performance of the Chinese manufacturing sector. Until recently the manufacturing sector in China has seen strong growth resulting in high demand, which pushed up prices. The current downturn in performance has meant a reduced demand for these materials and a sharp fall in their price.

The monthly input index fell 1.6% between September and October 2015, compared with no movement last month. This fall was driven by decreases in the price of crude oil, metals and chemicals, slightly offset by an increase in the price of fuel (see Table F and Figure F).

Crude oil annual prices have been falling since October 2013. The annual index fell 40.9% in the year to November 2015, Compared to a decrease of 40.7% in the year to October 2015. The monthly index for crude oil fell 7.3% between October and November 2015, compared with an increase of 1.9% between September and October 2015. The main contribution to both the annual and monthly indices came from imported crude petroleum and natural gas, which fell 40.3% in the year to November 2015, and 7.3% between October and November 2015.

In recent years, factors such as supply disruptions, concerns over the global economic recovery, instability in eurozone countries and the expectation of reduced demand have all affected oil prices. The current year on year drop is being driven by a significantly higher supply, primarily from OPEC countries, than global demand can keep up with. This oversupply in the market has caused prices to tumble and led to a number of American oil rigs temporarily ceasing production. The oversupply is so large that some analysts have suggested that oil prices could be significantly lower if it were not for the current Chinese level of demand for imported crude. This demand does not currently appear to come from their manufacturing sector, which by China’s recent standards is struggling, but from the desire to build up a surplus of oil while the price is relatively low.

The monthly index for fuel rose 1.6% between October and November 2015, compared with a rise of 0.5% last month. The increase was primarily due to gas distribution rising by 3.3%.

Core input price index (excluding purchases from the food, beverage, tobacco and petroleum industries)

The core input price index, in seasonally adjusted terms, fell 1.3% between October and November 2015, unchanged from last month. This index fell 8.3% in the year to November 2015, compared with a decrease of 7.0% in the year to October 2015.

The unadjusted index fell 8.3% in the year to November 2015, compared with a decrease of 6.7% last month; this is the largest decrease since records began in 1997. The monthly index fell 1.2% between October and November 2015, compared with a decrease of 0.6% last month. The decrease in the monthly rate is driven by falls in most of the indices except for fuel and home food materials, which showed slight growth. The biggest falls came from crude oil, imported metals and imported chemicals.

Input producer price index contribution to change in rate

The annual percentage rate for the input PPI in November 2015 fell 13.1%, compared with a decrease of 12.3% last month, resulting in a decrease in the annual rate of 0.8 percentage points. This was mainly due to falls in the contribution from fuel, imported chemicals, imported metals and imported food, this has been offset slightly by an increase in crude oil (Figure I).

Crude oil shows the biggest decrease, ranging from falls of 48.5% in January 2015 to 37.0% in May 2015. Other home produced materials shows the biggest increase, ranging from rises of 7.7% in March 2015 to 1.5% in October 2015.

Revisions

For this bulletin ( Reference tables 8R and 9R (229 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.

There are some large revisions in both the output and input indices caused by revisions from some data sources with high weights, for example, sugar and fish products. For more information about our revisions policy, see our website.

Background notes

  1. PPI standard errors

    We have published an article on the analysis of Producer Price Indices (PPI) using standard errors alongside this release. The article presented the calculated standard errors of the PPI during the period December 2014 to November 2015, for both month-on-month and 12-month growth.

  2. PPI Guidance

    Guidance on using indices in indexation clauses (197 Kb Pdf) has been published on our website. It covers producer prices, services producer prices and consumer prices.

    An up-to-date manual for the producer price index, including the import and export index is now available. PPI methods and guidance (1.18 Mb Pdf) provides an outline of the methods used to produce the PPI as well as information about recent PPI developments.

  3. Changing the way we publish datasets

    The 2 producer price datasets called Aerospace and Electronic Cost Indices (MM19) and Producer Price Indices (MM22) are now published on the Producer Price Index webpage with the statistical bulletin reference tables.

  4. How are we doing?

    We are constantly aiming to improve this release and its associated commentary. We would welcome any feedback you might have, and would be particularly interested in knowing how you make use of these data to inform your work. Please contact us via email: ppi@ons.gsi.gov.uk

  5. Article about rebasing the PPI and SPPI onto 2010=100

    As previously announced, we have taken forward the rebasing of the PPI onto a 2010=100 basis. The first published data using 2010=100 was released in November 2013. An article describing the results of this assessment was also published on 12 November 2013.

  6. Finding PPI data

    All of the data included in this statistical bulletin, alongside data for the full range of PPIs, is available in the associated reference tables. Also available are the datasets for the Aerospace and Electronic Indices and the Producer Price Indices, or these can be downloaded from the time series pages. There are PPI records (95.5 Kb Excel sheet) available which gives the higher, lower and equal to movements for each index. Each PPI has 2 unique identifiers: a 10 digit index number, which relates to the Standard Industrial Classification code appropriate to the index and a 4-character alpha-numeric code, which can be used to find series when using the time series dataset for PPI.

  7. Quality and methodology information

    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.

  8. European comparability

    The UK is required to compile and deliver the output PPI to Eurostat under the Short-Term Statistics Regulation. As a result, all EU countries must produce equivalent series on a comparable basis. Eurostat produce European aggregates for PPI and publish a monthly press release available on their website. This release uses the gross sector PPI as the headline figure here in the UK, we publish the top level PPI on a net sector basis. Detailed PPI figures for the UK and the rest of the EU are also published on Eurostat’s website.

  9. 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 (229 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% from 4 January 2011.

    The detailed input indices of prices of materials and fuels purchased ( Reference table 6 (229 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.

  10. 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.

  11. Definitions and explanations

    Definitions found within the main statistical bulletin are listed here:

    Index number

    A measure of the average level of prices, quantities or other measured characteristics, relative to their level for a defined reference period of location. It is usually expressed as a percentage above or below, but relative to, the base index of 100.

    Seasonally adjusted

    Seasonal adjustment aids interpretation by removing effects associated with the time of the year or the arrangement of the calendar, which could obscure movements of interest. Seasonal adjustment removes regular variation from a time series. Regular variation includes effects due to month lengths, different activity near particular events, such as bank holidays and leap years.

    Sampling variability

    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. Data in the bulletin are based on statistical samples and, as such, are subject to sampling ariability. If many samples were drawn, each would give different results.

    Prices

    All characteristics that determine the price of the products – including quantity of units sold, transport provided, rebates, service conditions, guarantee conditions and destination – are taken into account.

    The appropriate price is the basic price, which excludes VAT and similar deductible taxes directly linked to turnover, as well as all duties and taxes on the goods and services invoiced by the unit, whereas any subsidies on products received by the producer are added.

    Transport costs are included but only as part of the product specification.

    An actual transaction price and not a list price are given to show the true development of price movements.

    The output price index takes into account the quality changes in products.

    The price collected in period t refers to orders booked during period t (time of the order), not when the commodities leave the factory gates.

    For output prices on the non-domestic market, the price is calculated at national frontiers, FOB (free on board). This means that the seller pays for transportation of the goods to the port of shipment, plus loading costs, and the buyer pays freight, insurance, unloading costs and transportation from the port of destination to the factory.

  12. Accuracy

    Figures for the latest two months are provisional and the latest 5 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 are re-estimated every month. A routine seasonal adjustment review is normally conducted in the autumn each year.

    Every 5 years, producer price indices are rebased, and their weights updated to reflect changes in the industry. The rebasing article referred to in background note 1, informs users about work underway to rebase PPIs from a 2005=100 basis to a 2010=100 basis, and update the weights. PPIs will move to a 2010=100 basis from autumn 2013. More information about the impact of rebasing will be published as the project progresses and will be drawn to users’ attention in the regular statistical bulletin.
