In the United Kingdom, the official bank rate is the rate that the Bank of England charges banks and financial institutions for loans with a maturity of 1 day. It is the British Government's key interest rate for enacting monetary policy.^[1] It is more analogous to the US discount rate than to the federal funds rate. The security for the lending can be any of a list of eligible securities (commonly gilts) and the transactions are overnight repurchase agreements. Changes are recommended by the Monetary Policy Committee and enacted by the Governor.

On 2 August 2018 the Bank of England base rate was increased to 0.75%,^[2] but then cut to 0.25% on 11 March 2020,^[3] and shortly thereafter to an all-time low of 0.1% on 19 March, as emergency measures during the COVID-19 pandemic.^[4] It has since increased fourteen times to its current rate of 5.25% as of 03 August 2023.^[5]

The official bank rate has existed in various forms since 1694 and has ranged from 0.1% to 17%.^[6] The name and meaning (depositing vs lending) of this key interest rate has changed over the years. The current name, Official Bank Rate, was introduced in 2006^[6] and replaced the previous Repo Rate (repo is short for repurchase agreement) in use since 1997. Previously (between 1981 and 1997) the name was Minimum Band 1 Dealing Rate and prior to that the Minimum Lending Rate.
