The three additional Indexed Long-Term Repo operations will allow banks, building societies and broker-dealers to obtain liquidity in exchange for assets such as mortgage loans.
This will enable banks to carry on lending if markets become stressed, and has been described as a 'precautionary measure'.
The Bank of England said it will 'continue to offer liquidity insurance via its other facilities' and will 'continue to monitor market conditions carefully and keep its operations under review'.
The operations are in addition to the regular ILTR operations which will continue to take place once a month.
Mark Carney is due in parliament today to give evidence on the Bank's preparations for the EU referendum.
