Central Bank: Meaning and Functions (ICSE Class 10 Economics)

Updated 17 October 2026 · Fact-checked

A central bank is the apex institution of a country's monetary and banking system; in India it is the Reserve Bank of India. Its main functions are monopoly of note issue, banker to commercial banks (bankers' bank), banker, agent and adviser to the government, custodian of foreign exchange reserves and lender of the last resort. It works for the public interest, not for profit.

Notice that the central bank sits at the centre and serves banks and the government through six functions, aiming at stability rather than profit.

Understand Functions of a Central Bank

Meaning. The central bank sits at the centre of the banking system, issues currency, controls credit and supervises banks. It does not deal with the public in the way commercial banks do.

Functions.
1. Monopoly of note issue: sole right to issue currency notes, so notes are uniform and the money supply can be controlled. In India the RBI issues notes (coins are minted by the Government); the one-rupee note is issued by the Government of India.
2. Bankers' bank: commercial banks keep cash reserves with it; it acts as a clearing house to settle cheques between banks by book entries; it supervises and regulates banks.
3. Banker, agent and adviser to the government: keeps government accounts, gives short-term loans (ways and means advances), manages public debt and issues government securities, and advises on financial and monetary matters.
4. Custodian of foreign exchange reserves: holds and manages the country's reserves of foreign currencies and gold, helps keep the exchange rate stable and administers foreign exchange rules.
5. Lender of the last resort: when a commercial bank in crisis cannot get funds from any other source, the central bank helps by rediscounting bills or lending against approved securities, charging the bank rate.
6. Controller of credit: uses monetary policy tools (taken up in the next chapter section).

Central bank versus commercial bank. Central bank: apex, owned by the government, aims at stability, issues notes, deals with banks and the government. Commercial bank: aims at profit, accepts deposits from the public, lends to individuals and businesses.
