What you need to know about reserve requirement...
In exchange for being allowed to lend money out to customers, banks are often required to keep a certain amount of deposits in reserve to cover potential withdrawals. This minimum is usually a percentage of the deposit liabilities owed to customers. The reserves usually consist of cash held in the bank's vaults, and its balance held with its central bank. UK banks used to set voluntary reserve targets in contracts with the Bank of England. This was abolished with the introduction of quantitative easing and interest on excess reserves in 2009.
