As well as maintaining a broad overview of the financial system, the Bank contributes to the maintenance of financial stability by:
■ making funds available in the markets to deal with fluctuations in liquidity;
■ overseeing financial system infrastructure systemically significant to the UK, in particular payments systems whether based in the UK or abroad;
■ undertaking, in exceptional circumstances, official financial operations, in accordance with the Tripartite arrangements in the Memorandum of Understanding on financial stability, to limit the risk of problems in or affecting particular institutions spreading to other parts of the financial system.
