describe the function of lender of last resort performed by the central bank
Lender of last resort A lender of last resort (LOLR) is the institution in a financial system that acts as the provider of liquidity to a financial institution which finds itself unable to obtain sufficient liquidity in the interbank lending market and other facilities or sources have been exhausted. It is, in effect, a government guarantee of liquidity to financial institutions. Since the beginning of the 20th century, most central banks have been providers of lender of last resort facilities, and their functions usually also include ensuring liquidity in the financial market in general. The objective is to prevent economic disruption as a result of financial panics and bank runs spreading from one bank to the next from a lack of liquidity in one. Different definitions of the lender of last resort exist in literature. A comprehensive one is that it is "the discretionary provision of liquidity to a financial institution (or the market as a whole) by the central bank in reaction to an adverse shock which causes an abnormal increase in demand for liquidity which cannot be met from an alternative source".[1]
