In Blue Book 2019, we have made considerable progress in improving how we compile estimates of gross domestic product (GDP), where we have used the foundations of a new framework to inform headline GDP estimates. This includes:
- progress in incorporating a wider set of more appropriate product deflators for each transaction, confronting these at a detailed level for the first time
- full integration of the institutional sectors into the balancing process of the Supply and Use framework
- improving our estimates of current price GDP by using new data sources to give information on the diversification of the services economy and the costs incurred by businesses
Further information is outlined in the National Accounts articles: Blue Book 2019 impacts on GDP current price and chained volume measure estimates: 1997 to 2016 that was published on 20 August 2019.
There are also a number of methodological improvements that will be incorporated into this year’s Blue Book. Stand-alone articles for National Accounts articles: Impact of Blue Book 2019 changes on gross fixed capital formation and business investment; National Accounts articles: Changes to the capital stock estimation methods for Blue Book 2019 and National Accounts articles: Improvements to the processing of Non-Profit Institutions Serving Households (NPISH) published on 20 August 2019 provide further details of these.
Nôl i'r tabl cynnwys2. Executive summary
This article details indicative estimates of the impact on UK trade in Blue Book 2019 and Pink Book 2019 – consistent with the quarterly national accounts (QNA) to be published on 30 September 2019.
This article focuses on the period from 1997 to 2016 and covers annual revisions to both current prices and chained volume measures and the trade implied deflator.
We have embarked upon and are delivering against an ambitious development plan for UK trade statistics. For Blue Book and Pink Book 2019 we are making improvements to the balance of payments (BoP) adjustments within trade in goods, and incorporating estimates of UK monetary financial institutions’ intragroup fees and cost recharges within trade in services. Improvements have been made to the way Weight Modified Consumer Price Indices (WMCPIs) are currently used in the deflation of trade in services. We have also improved the method to produce the trade in goods fuel deflator by using a better weighting system.
Trade in services received balancing adjustments, this was the largest contributor to the annual revisions. This is as a result of the annual supply and use balancing process, that is, the process used to reconcile the three approaches to GDP: income, output and expenditure.
Nôl i'r tabl cynnwys3. Methodological changes to UK trade in goods
This section details the methodological improvements we are making to trade in goods for Blue Book and Pink Book 2019.
We are improving our balance of payments (BoP) adjustments which are applied to trade in goods. Her Majesty's Revenue and Customs (HMRC) is the main source for our trade in goods data, delivering administrative data each month collected on an Overseas Trade Statistics (OTS) basis; this measures the physical movement of goods in and out of the UK. However, such data are on a different basis from that required for balance of payments statistics. To conform to the International Monetary Fund (IMF) definition (PDF, 3.01MB), we have to make various adjustments to certain transactions which are not reported to HMRC and, conversely, to exclude certain transactions that, although are reported by HMRC, do not involve a change in economic ownership.
One of the improvements revises the method for allocating the adjustments for merchanting and adjustments for goods sent abroad for processing to products. Merchanting is the purchase of a good by a resident from a non-resident and the subsequent resale of the good to another non-resident, without the good ever entering the resident economy. The value of these goods will not be present in the OTS data since they do not cross the customs border. Goods sent abroad for processing are goods that are exported or imported for processing where the enterprise doing that processing is not the economic owner. The value of these goods is present in the OTS data as they cross the customs border. The processor however does not have economic ownership over the goods, so the flow should not be included on a BoP basis.
Both of these adjustments are collected via the International Trade in Services Survey (ITIS) but these data are not available on a product basis. Product classifications are designed to categorise products that have common characteristics. We are now utilising the trade in goods microdata from HMRC to allocate these adjustments to a product based on the industry that reported the transaction. Linking the data in this way assumes that a trader operates in a single industry. While this may hold for simple firms, for more complex firms who have operations spanning multiple industries, the matching method used in this release will provide a more accurate apportionment of trade values to industry.
In addition, the processing of the trade in goods country by commodity dataset has been improved, maintaining the unrounded value to increase the accuracy of this granular dataset. Following Blue Book and Pink Book 2019, publications of the country by commodity dataset will be in British pounds rather than millions. While this has no impact on total trade in goods, it results in some reallocation across both the product and country dimensions.
The method to produce the trade in goods fuel deflator has been improved for Blue Book 2019. Prices for petrol, diesel and kerosene from Bloomberg are weighted using the Digest of UK Energy statistics publication; which shows the volumes of each commodity traded on an import and export basis.
Nôl i'r tabl cynnwys4. Methodological changes to UK trade in services
For Blue Book and Pink Book 2019 in addition to balancing adjustments, we have incorporated a range of trade-specific methodological improvements. One of these improvements is the inclusion of estimates of UK monetary financial institutions’ intragroup fees and cost recharges in trade in services. This is in line with our planned improvements and ongoing developments of trade statistics. The Bank of England collects these data using its Profit and Loss (PL) form. Transactions between residents and non-residents will be included within trade in services for Blue Book 2019. Transactions between UK institutions are already captured in the income and output measures of GDP.
Intragroup fees and cost recharges cover:
- intragroup fees, including investment banking, advisory, brokerage, underwriting, insurance, loans and advances where these cannot be separately identified and explicitly reported within those items on Form PL
- cost recharges, applied when the costs of a centrally managed service are allocated and charged to each group entity; for example, software for the whole group may be purchased by one group entity but then recharged to other group entities
- other intragroup operating income and expenditure; any intra-group service income and expenditure not covered by intragroup fees or cost recharges
Example of cost recharging from the Bank of England’s profit and loss definitions (referred to on Form PL as transfer pricing):
Suppose the UK entity brokers a deal on behalf of its US subsidiary, making a £500 million trading profit on the deal. The £500 million is then transferred back to the US subsidiary which owns the trading portfolio. The US subsidiary is charged £10 million by the UK reporter for the service provided. This charge can be either implicit (a dealing profit of £500 million, of which only £490 million is transferred back), or explicit (a cost recharge expense of £10 million by the US subsidiary). Regardless of the exact transaction, reporting should be as follows:

Weight Modified Consumer Price Indices (WMCPIs) are currently used in the deflation of trade in services. The methodology for constructing WMCPIs has been improved for Bluebook 2019. We have updated the weight given to different currencies in the construction of the indices to better reflect the relative weight; these weights will now be updated every five years. A further four countries have been incorporated into this matrix, including China and India. These were selected based on the value of service trade with these countries.
The underlying data used to form export WMCPIs have been changed. GDP(O) deflators have replaced foreign CPI data, reflecting that export prices are more influenced by domestic input-price changes. Import prices continue to be formed from foreign CPI data.
The basket of currencies used to adjust exchange rates has also been modified. This reflects that international trade conducted by UK firms is largely agreed and transacted in three dominant currencies: British Sterling, US Dollar and the Euro. The proportion of each currency used in trade is calculated separately for exports and imports.
Nôl i'r tabl cynnwys5. Indicative impact of improved methods to UK trade balance
The indicative impact of the improvements we are making to the UK trade balance in current prices range from a downward revision of £1.4 billion in 2016 to an upward revision of £6.3 billion in 2013 (Table 1). The £6.3 billion upward revision to the UK trade balance in 2013 means the deficit has been revised from £29.0 billion to £22.8 billion (Table 2).
In Blue Book 2019, we will introduce a new framework to produce gross domestic product (GDP), both in current prices and in volume terms. Upwards revisions to the trade in services balance are largely as a result of the annual supply and use balancing process (that is, the process used to reconcile the three approaches to GDP; income, output and expenditure). Further information is available in National Accounts articles: Blue Book 2019 indicative impacts on GDP current prices and chained volume measure estimates: 1997 to 2016.

The package of planned revisions set out in this article introduces a number of improvements in line with our published UK trade development plan. In agreement with the work to expand and improve UK trade statistics, new statistics have been published including trade in goods by industry, trade in services by industry, as well as more granular trade in services data by service type and partner country. This is alongside more developments planned for the future, such as services trade by enterprise characteristics. Further details can be found in the article New frontiers in trade analysis published 29 January 2019.
