This provisional Market Notice sets out the expected design for a new financial stability tool – the Contingent NBFI Repo Facility – that the Bank of England intends to invite applications for later this year. The Bank is expanding its toolkit to intervene where severe liquidity-related dysfunction in gilt markets threatens financial stability, by developing a facility that will allow eligible Non-Bank Financial Institutions (NBFIs) to borrow cash against gilts at times of severe gilt market dysfunction.
