Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what the average annual interest was on the UK’s foreign reserves in each of the last 10 years.

Information is not held in the form requested and could only be produced at a disproportionate cost due to the complexities of the analysis required.

The Exchange Equalisation Account (EEA) Annual Report and Accounts contains information on the financial position of the Government’s foreign exchange holdings, including the income and asset position. Details of the interest rate on special drawing rights is published by the IMF on a weekly basis. Rates of return may therefore be estimated with reference to this published information.
