RBI Functions & Structure

1Establishment and the RBI Act

The Reserve Bank of India was established on 1 April 1935 under the Reserve Bank of India Act, 1934. The bank was set up on the recommendation of the Hilton Young Commission (the Royal Commission on Indian Currency and Finance). The Act year and the start year are one year apart — that gap is a standard trap.

Ownership later changed: the RBI was nationalised on 1 January 1949. Headquarters today are in Mumbai; the bank originally sat in Kolkata.

Figure. Hilton Young Commission → RBI Act 1934 → bank opens 1 April 1935 → nationalised 1 January 1949. The one-year Act-to-start gap is the exam trap.

2Currency note issue

The RBI is the sole authority to issue currency notes in India under the minimum reserve system. The standing exception is the one-rupee note: the Re 1 note and all coins are issued by the Government of India (Ministry of Finance), not by the RBI.

A useful confirmation of the exception: the Re 1 note bears the signature of the Finance Secretary, not the RBI Governor.

Figure. Minimum-reserve note issue is the RBI's job except the standing exception: the Re 1 note and all coins are Government of India (Finance Secretary signs Re 1).

3Banker to the government

One of the RBI's classic central-bank roles is to act as banker, agent and adviser to the central and state governments. In that capacity it manages government accounts, handles receipts and payments, and advises on debt and monetary matters.

This is distinct from fiscal policy itself: the government spends and taxes; the RBI is the banker and adviser on the monetary side of the relationship.

Figure. Banker / agent / adviser to governments is the RBI hat — not fiscal policy itself. The government spends and taxes; the RBI banks and advises on the monetary side.

4Banker to banks and lender of last resort

As banker to banks, the RBI maintains banks' reserve accounts and sits at the centre of the interbank settlement system. When the banking system faces a liquidity crunch that markets cannot clear, the RBI can act as lender of last resort — providing emergency liquidity to solvent banks against eligible collateral.

Lender of last resort is a stability function, not everyday retail lending. Ordinary borrowers deal with commercial banks; banks deal with the RBI for reserves and emergency support.

Figure. Everyday path: banks keep reserve accounts at the RBI. Stability path: lender of last resort is emergency liquidity to solvent banks, not retail lending.

5Controller of credit

As monetary authority, the RBI regulates money supply and credit in the economy. The tools named in this topic's source notes are the repo rate, CRR, SLR and open market operations (OMO). How those tools are sized and ordered belongs with the monetary-policy topic; here the exam point is that credit control is an RBI function.

Raising policy rates or reserve ratios tends to tighten credit; the reverse tends to ease it. Direction of effect is the tested idea, not a current published percentage.

Figure. Credit-control stance, not a published rate history: raising repo / CRR / SLR or selling in OMO tightens; the reverse eases. Direction is the tested idea.

1. Name the hatCredit control is an RBI monetary-authority function, not a SEBI or Finance Ministry rate vote.
2. Pick the tool familyPolicy rate (repo), reserve ratios (CRR/SLR), or OMO — all act on liquidity and lending capacity.
3. Read the directionHikes and security sales tighten; cuts and purchases ease. Do not invent a 'current' percent.

6Regulator, FEMA and payments

Beyond issuing notes and running monetary tools, the RBI licenses and supervises banks. It also manages foreign exchange under the Foreign Exchange Management Act (FEMA) and oversees India's payment and settlement systems.

These are separate hats from 'banker to government': supervision and FX/payments oversight are regulatory and systems roles, not the government account relationship.

Figure. Three regulatory hats distinct from banker-to-government: license and supervise banks, manage FX under FEMA, oversee payment and settlement systems.

7Core functions at a glance

Bank exams often ask for a clean list of the RBI's core functions rather than a deep dive into one tool. The source sheet groups them as: monetary authority, issuer of currency, banker to the government, banker to banks (including lender of last resort), regulator of the banking and payment systems, and manager of foreign exchange reserves.

Use this concept as the night-before checklist; the earlier concepts unpack each row.

No diagram — six functions in a checklist carry no proportion, flow or hierarchy a figure must show; the core-functions table is the night-before artefact.

8Governor and Central Board

The RBI is headed by a Governor and by Deputy Governors. Its affairs are governed by the Central Board of Directors. Exam questions at this topic's depth usually stop at that structure — they do not require naming every current office-holder.

Do not confuse the Central Board (governs the bank's affairs) with the Monetary Policy Committee (sets the policy repo). MPC composition lives in the monetary-policy topic.

Figure. Governor and Deputies run the bank; the Central Board governs its affairs. Do not swap that Board for the Monetary Policy Committee that sets the policy repo.
