This article provides details of forthcoming changes and their indicative impact on the main Balance of Payments and International Investment Position estimates. These changes will be introduced when revised figures for the UK National Accounts and Balance of Payments, consistent with Blue Book 2017 and Pink Book 2017, are published on 29 September 2017.


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
  • 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.
