Functions of a Central Bank and Difference from Commercial Banks (ICSE Class 10)
Updated 17 October 2026 · Fact-checked
A central bank is the apex monetary institution of a country that regulates the money and banking system in the public interest; in India it is the Reserve Bank of India (RBI). Its main functions are issuing currency, acting as banker to the government, bankers' bank and lender of last resort, custodian of foreign exchange and controller of credit. Unlike commercial banks, it does not work for profit or deal with the public.
Notice that the RBI sits at the centre of six functions, from issuing currency to controlling credit, and it works for the public interest, not profit.

Understand Functions of a Central Bank and Difference from Commercial Banks
1. Meaning
A central bank is the highest bank of a country. It controls the monetary and banking system, works in the public interest and not for profit, does not deal directly with the general public, and is usually owned by the government. There is only one in a country. In India it is the Reserve Bank of India, set up in 1935 and nationalised in 1949, with its head office in Mumbai.
2. Functions
1. Issue of currency: only the central bank can issue notes, which gives uniformity, public confidence and control over the money supply. In India the RBI issues all notes except the one-rupee note; coins and the one-rupee note are issued by the Government of India and circulated through the RBI.
2. Banker, agent and adviser to the government: keeps the government's accounts, receives and makes payments, manages public debt, gives short-term loans and advises on monetary and economic matters.
3. Bankers' bank and supervisor: commercial banks keep part of their deposits with it as cash reserves; it licenses, inspects and supervises banks to protect depositors.
4. Lender of last resort: when a commercial bank cannot get funds anywhere else, the central bank lends against approved securities to prevent a failure.
5. Clearing house: settles claims between banks by adjusting their accounts with it, without moving cash.
6. Custodian of foreign exchange: holds the country's foreign currency and gold reserves and administers foreign exchange rules.
7. Controller of credit: regulates the volume and cost of bank credit to control inflation and support growth. Quantitative tools: repo rate (the rate at which it lends to banks), reverse repo rate, cash reserve ratio (CRR), statutory liquidity ratio (SLR) and open market operations. Qualitative tools: margin requirements, moral suasion and directing credit to priority sectors.
8. Developmental and other functions: promoting banking in rural areas, collecting and publishing data.
3. Central bank versus commercial banks
| Basis | Central bank | Commercial bank |
|---|---|---|
| Position | Apex bank | Works under the central bank |
| Objective | Public interest | Profit |
| Dealings | Not with the general public | With the public: deposits and loans |
| Note issue | Monopoly | Cannot issue |
| Number | One in a country | Many |
| Control | Controls banks | Controlled by it |
| Ownership | Usually government | Public or private sector |
| Lender of last resort | Yes | No |
4. Why credit control matters
Too much credit raises prices (inflation); too little slows production and jobs. By changing the rates and reserve ratios, the central bank makes loans dearer or cheaper for banks and so for the public.
5. Writing
Name the function, then explain it in one or two sentences. Do not mix foreign exchange custody (reserves) with note issue.

- (c) Moral suasion: it persuades banks to lend carefully; margin requirements or directing credit to priority sectors are other choices.
- Less credit reduces demand and slows price rise, though too much tightening can reduce growth and jobs.
Answer: (a) Controller of credit; (b) higher repo rate and CRR cut lending; (c) moral suasion.

Practice questions on Functions of a Central Bank and Difference from Commercial Banks

Q1 · 2 marks · Very short answerBoard level
Write two functions of a central bank.
Hint
Think notes and government.
Answer
It issues the currency of the country and acts as banker to the government. (Any two functions.)
Q2 · 4 marks · Short answerHarder board level
Suppose a person says that the Reserve Bank can give a housing loan to a salaried person. Is this correct? Explain with reference to its dealings.
Hint
Public dealings.

This is not correct. A central bank does not accept deposits from or lend to the general public. It deals with the government and the commercial banks. A housing loan to an individual is given by a commercial bank, which works for profit and deals directly with the public.
Q3 · 4 marks · Short answerHarder board level
Explain the function of the central bank as bankers' bank.
Hint
Reserves, supervision.
Answer
Commercial banks keep part of their deposits with the central bank as cash reserves (the cash reserve ratio).

Q4 · 4 marks · Short answerHarder board level
In what four ways does a commercial bank differ from the apex bank of a country?
Hint
Objective, public, note issue, number.
Answer
Objective: public interest versus profit. Public dealings: none versus deposits and loans. Note issue: monopoly versus none. Number: one versus many. Control: the central bank controls; commercial banks are controlled.
Q5 · 4 marks · Case-basedHOTS / competency
Suppose a rumour causes depositors to rush to a bank to withdraw savings, and the bank has little cash. Describe how the central bank can prevent the crisis from spreading and why this matters.
Hint
Last resort and supervision.
Answer
As lender of last resort the central bank can lend cash to the bank against approved securities, so that depositors are paid. As supervisor it can inspect the bank and reassure the public. This matters because loss of confidence in one bank can spread to others and harm the whole banking system and the economy.
