The core banking laws: RBI Act, BR Act, SBI Act and the Nationalisation Acts
Understand
A bank holds other people's money, so the State cannot leave banking entirely to private contracts. Laws decide who may run a bank, how much cash and safe assets it must keep, who supervises it and what happens when it fails. In India this framework rests on a handful of Acts, and each has a distinct job. The Reserve Bank of India Act, 1934 creates the regulator. It set up the RBI (which started work on 1 April 1935), gives it the sole right to issue bank notes, makes it banker to the Government and to banks, and contains the cash reserve rule for scheduled banks (Section 42) and the Monetary Policy Committee (Section 45ZB). The Banking Regulation Act, 1949 regulates the banks themselves: what 'banking' means, which businesses a bank may do, licensing, the statutory liquidity ratio, management, audit, mergers and winding up. Think of it this way: the RBI Act is about the RBI; the BR Act is about the banks the RBI regulates. Ownership laws sit beside these. The State Bank of India Act, 1955 converted the Imperial Bank of India into SBI. The Banking Companies (Acquisition and Transfer of Undertakings) Act, 1970 nationalised 14 banks (each with deposits above ₹50 crore) taken over in July 1969, and the Act of 1980 did the same for 6 more banks in April 1980. These two Acts are still the 'constitution' of the nationalised banks, which is why they are called 'corresponding new banks'. In 2025 all five of these Acts were amended together by the Banking Laws (Amendment) Act, 2025.
Rule
RBI Act, 1934: Section 22 — sole right to issue bank notes; Section 42 — CRR for scheduled banks; Section 45ZB — Monetary Policy Committee; Chapter III-B (Section 45-IA onwards) — registration of NBFCs.
RBI was nationalised with effect from 1 January 1949; the RBI Act itself is older than the BR Act.
BR Act, 1949 (passed as the Banking Companies Act, 1949; renamed in 1966): Section 5(b) defines banking — accepting deposits from the public for lending or investment, repayable on demand or otherwise and withdrawable by cheque, draft or order.
BR Act: Section 6 lists permitted business; Section 22 — no company may carry on banking without an RBI licence; Section 24 — SLR (maximum 40% of NDTL); Section 35A — RBI's power to give directions; Section 45ZA — nomination for deposits.
BR Act, Section 56 applies the Act to co-operative banks with modifications; the BR (Amendment) Act, 2020 widened RBI's powers over co-operative banks.
Other laws to place correctly: Negotiable Instruments Act, 1881 (cheques), DICGC Act, 1961 (deposit insurance), RRB Act, 1976, SARFAESI Act, 2002 (recovery), PMLA, 2002 (anti-money laundering), Credit Information Companies (Regulation) Act, 2005 and Payment and Settlement Systems Act, 2007.
Example
Suppose a fintech company in Pune starts taking ₹10,000 deposits from the public, repayable on demand and withdrawable by cheque, and lends the money onward. That activity is 'banking' under Section 5(b) of the BR Act. Without a licence under Section 22 it is illegal, whatever the company calls itself. If a licensed bank keeps less cash with the RBI than required, the penalty comes from Section 42 of the RBI Act; if it keeps too few liquid assets, the SLR rule in Section 24 of the BR Act applies.
| Law | Year | Main job |
|---|---|---|
| RBI Act | 1934 | Creates RBI; note issue, CRR (s.42), MPC (s.45ZB), NBFC regulation |
| Banking Regulation Act | 1949 | Licensing (s.22), SLR (s.24), directions (s.35A), nomination (s.45ZA) |
| SBI Act | 1955 | Imperial Bank of India converted into SBI |
| Banking Companies (Acquisition…) Acts | 1970 and 1980 | Nationalisation of 14 + 6 banks |
| Negotiable Instruments Act | 1881 | Cheques, bills, promissory notes; s.138 cheque dishonour |
Common mistake
CRR comes from Section 42 of the RBI Act, but SLR comes from Section 24 of the BR Act — do not swap the Acts.
The 1969 nationalisation (14 banks) is given effect by the 1970 Act, not by an 'Act of 1969' (the 1969 Ordinance and Act were replaced).
The BR Act was originally the Banking Companies Act, 1949; the name 'Banking Regulation Act' dates from 1966.
The RBI Act (1934) is older than the BR Act (1949), even though RBI was nationalised only in 1949.
