Functions of the Reserve Bank of India (RBI)

Updated 10 October 2026 · Fact-checked

The Reserve Bank of India is India's central bank. It issues currency notes (except one-rupee notes and coins, which the Government issues), acts as banker and debt manager to the Government, acts as banker and lender of last resort to banks, keeps the country's foreign exchange reserves, and controls credit through monetary policy.

Understand Reserve Bank of India and Its Functions

A central bank is the apex bank of a country. It does not serve the public like a normal bank. It runs the money and banking system and keeps it stable. In India, this role is played by the Reserve Bank of India (RBI). It began work in 1935 and was nationalised in 1949.

Think of the RBI as the manager of the whole banking system. Commercial banks take deposits and give loans to people and businesses to earn profit. The RBI does not work for profit as its main aim. Its aim is currency stability, a sound banking system and economic growth.

The main functions are these:

Currency issue: The RBI issues currency notes of ₹2 and above. The Government of India issues the ₹1 note and all coins. The RBI puts all of them into circulation.
Banker to the Government: The RBI keeps the Government's accounts, receives and makes payments for it, gives short-term advances, manages public debt and raises loans for it. It also advises the Government on money matters.
Banker's bank: Banks keep part of their deposits with the RBI as cash reserves. If a bank runs short of funds, the RBI lends to it. This is why the RBI is called the lender of last resort. It also supervises banks and acts as the clearing house for settling inter-bank payments.
Custodian of foreign exchange reserves: The RBI holds and manages the country's foreign currency and gold reserves. It administers foreign exchange rules (under FEMA) and steps into the forex market to limit excessive volatility. The exchange rate itself is market-determined, not fixed by the RBI.
Controller of credit: It uses tools such as the repo rate, reverse repo rate, CRR and SLR to expand or reduce credit in the economy.

A clear difference helps in the exam. Commercial banks deal with the public and earn profit. The RBI deals with the Government and banks, regulates them, and does not compete with them for ordinary deposits and loans.

Key formulas to remember

Currency issue: RBI issues notes of ₹2 and above; Government of India issues the ₹1 note and all coins; RBI puts them into circulation; The RBI does not issue coins. Do not say the RBI issues every coin or note.
Banker to Government: RBI = Government's banker + agent + adviser + debt manager; Includes accepting receipts, making payments, ways-and-means advances and managing public debt.
Banker's bank: RBI = custodian of bank cash reserves + lender of last resort + clearing house + supervisor; Banks keep CRR balances with the RBI.
Custodian of reserves: RBI = keeper of foreign exchange and gold reserves + administrator of forex rules (FEMA) + curbs excess forex volatility; Reserves are held for the nation, not for any single bank. The exchange rate is market-determined.
Credit control tools: Quantitative: Bank Rate, Repo, Reverse Repo, CRR, SLR, open market operations; Qualitative: margin requirements, moral suasion, selective credit control; Details belong to the monetary policy topic.

How to solve Reserve Bank of India and Its Functions questions

Most RBI questions test one thing: can you match a function to the right role. Use this method.

1Read the question and spot the keyword: note, Government, banks, foreign, credit, profit.
2Match the keyword to a role: note issue, banker to Government, banker's bank, custodian of reserves, or controller of credit.
3If the question asks for a 'not a function' or 'except' option, find the one that a commercial bank does (for example, accepting deposits from the public for profit).
4Check for traps: one-rupee notes and coins come from the Government, not the RBI.
5For 'difference' questions, compare on purpose, customers, profit motive and note issue.
6Eliminate options that mix up roles, then pick the one that fits fully.

Quickest way: Keyword-to-role matching

When to use it: Use for any one-line MCQ on RBI functions or RBI versus commercial banks.

Note or currency → RBI is the issuer (except ₹1 note and coins).
Government accounts, public debt → banker to Government.
Cash reserve, lender of last resort, clearing → banker's bank.
Gold or foreign currency → custodian of reserves.
Deposits from public, loans for profit → commercial bank, not RBI.

Common mistakes in Reserve Bank of India and Its Functions

Saying the RBI issues all currency including the ₹1 note and coins.
Students remember 'sole note issuer' and stop there.
Fix: Remember that the Government of India issues the ₹1 note and coins. The RBI issues other notes and circulates everything.
Treating the RBI as a normal bank that takes deposits from the public.
The word 'bank' in the name misleads.
Fix: The RBI deals with the Government and banks. Public deposits and retail loans are commercial bank work.
Mixing banker to Government with banker's bank.
Both use the word 'banker'.
Fix: Ask who the customer is. Customer is Government → banker to Government. Customer is banks → banker's bank.
Thinking lender of last resort means the RBI lends to anyone in trouble.
The phrase sounds general.
Fix: It means the RBI lends to banks when they cannot get funds elsewhere, to protect the banking system.
Saying foreign reserves belong to commercial banks or the Government's budget.
Confusion about who holds reserves.
Fix: The RBI is the custodian of the country's foreign exchange and gold reserves.

Example 1

Which of the following is NOT a function of the Reserve Bank of India? (A) Issuing currency notes (B) Acting as banker to the Government (C) Accepting fixed deposits from the general public to earn profit (D) Keeping the country's foreign exchange reserves

Show the solution

List the RBI's roles: note issue, banker to Government, banker's bank, custodian of reserves, credit control.
Option A is note issue, an RBI function.
Option B is banker to Government, an RBI function.
Option D is custodian of foreign reserves, an RBI function.
Option C is ordinary commercial banking for profit, which the RBI does not do.

Answer: (C)

Example 2

A commercial bank faces a sudden cash shortage and cannot borrow from anywhere else. To which role of the RBI does the bank turn? (A) Issuer of coins (B) Lender of last resort as banker's bank (C) Custodian of gold (D) Adviser on public debt

Show the solution

The borrower is a bank, so the role is banker's bank, not banker to Government.
A bank that cannot raise funds elsewhere asks the central bank to lend.
This role is called lender of last resort.
Options A, C and D deal with coins, gold and Government debt, which are not about bank liquidity.

Answer: (B)

Exam tips

Expect 'which is NOT a function' questions. Eliminate by finding the profit-making commercial banking activity.
Learn the exact exception: the ₹1 note and coins are issued by the Government of India.
Link each role to its customer: Government, banks, the nation's reserves, the public (via credit control).
For RBI versus commercial bank, remember purpose: stability and regulation versus profit and public dealing.
Credit control tools are asked under monetary policy, so revise them with that topic.
