Explanation: As a Banker to Banks, the Reserve Bank also acts as the ‘lender of the last resort’.

It can come to the rescue of a bank that is solvent but faces temporary liquidity problems by supplying it with much needed liquidity when no one else is willing to extend credit to that bank.

The Reserve Bank extends this facility to protect the interest of the depositors of the bank and to prevent possible failure of the bank, which in turn may also affect other banks and institutions and can have an adverse impact on financial stability and thus on the economy.
