The Bank also says Brexit economic risks have already "begun to crystallise".

The report said the announcement was created to reduce pressure on lenders "to restrict the provision of financial services, including the supply of credit and support for market functioning".
Mr Carney also signalled the possibility of the Bank reviving its quantitative easing programme, as well as other actions to contain the fallout from the European Union referendum.
