End-of-Day Gilt Reference Prices

Tradeweb and FTSE Russell are the providers of Gilt and Treasury bill end-of-day reference prices, succeeding the previous provision by the U.K. Debt Management Office (DMO).

Tradeweb and FTSE Russell produce end-of-day Gilt reference prices in a manner consistent with IOSCO principles. Tradeweb calculates the reference prices based on data from the Tradeweb dealer-to-client U.K. Gilt trading platform; FTSE Russell operates as the administrator of the reference prices and uses these prices in the calculation of the FTSE Actuaries UK Gilts Index Series.
