How has the Liquidity Saving Mechanism reduced banks’ intraday liquidity costs in CHAPS?

Banks require intraday liquidity to settle payments in CHAPS, the United Kingdom’s high-value sterling payment system. In April 2013, the Bank of England introduced a Liquidity Saving Mechanism (LSM) into the infrastructure used to settle CHAPS payments. The LSM has reduced CHAPS banks’ intraday liquidity requirements by around 20% (or £4 billion). The LSM has reduced incentives for banks to adopt adverse behaviours to economise on their intraday liquidity requirements, thus enhancing the resilience and efficiency of CHAPS.
