Bank Nationalisation and Mergers in India: 1949 to 2020
Complete notes for banking exams on the nationalisation of the RBI and of banks in 1969 and 1980, and every public sector bank merger from 1993 to 2020.

Indian banking has been reshaped twice by the state: once by taking private banks into public ownership, and again by folding those public banks into one another. Nationalisation ran from 1949 to 1980 and was meant to push credit towards agriculture, small industry and the districts the private banks had ignored. Amalgamation ran from 1993 to 2020 and was meant to leave fewer, larger, better capitalised public sector banks. Every banking paper asks from this timeline, and the questions are almost always a year, a number or the name of the bank a smaller bank went into.
How public banking was built
The Reserve Bank of India began as a shareholders' bank on 1 April 1935 under the Reserve Bank of India Act, 1934, and was taken into public ownership on 1 January 1949 by the Reserve Bank of India (Transfer to Public Ownership) Act, 1948. The Banking Regulation Act was passed the same year and remains the law under which banks are licensed, supervised and amalgamated. In 1955 the Imperial Bank of India, itself formed in 1921 from the presidency banks of Bengal, Bombay and Madras, was taken over by the state and renamed the State Bank of India under the State Bank of India Act, 1955, on the recommendation of the All India Rural Credit Survey Committee. The State Bank of India (Subsidiary Banks) Act, 1959 brought the banks of the former princely states in as its associate banks.
The two rounds of nationalisation
On 19 July 1969 the government issued an ordinance nationalising fourteen commercial banks, each with deposits of fifty crore rupees or more. They were Allahabad Bank, Bank of Baroda, Bank of India, Bank of Maharashtra, Canara Bank, Central Bank of India, Dena Bank, Indian Bank, Indian Overseas Bank, Punjab National Bank, Syndicate Bank, United Commercial Bank, Union Bank of India and United Bank of India. The Supreme Court struck the 1969 law down in Rustom Cavasjee Cooper v. Union of India, the Bank Nationalisation case, on the ground that the compensation provided was not adequate, and a fresh Act was passed at once. A second round followed on 15 April 1980, when six banks with deposits of two hundred crore rupees or more were nationalised: Andhra Bank, Corporation Bank, New Bank of India, Oriental Bank of Commerce, Punjab and Sind Bank, and Vijaya Bank.
Institutions that followed
| Year | Milestone |
|---|---|
| 1935 | Reserve Bank of India begins working under the RBI Act, 1934 |
| 1949 | RBI nationalised; Banking Regulation Act enacted |
| 1955 | Imperial Bank of India becomes the State Bank of India |
| 1969 | Fourteen banks nationalised; the Lead Bank Scheme begins |
| 1975 | Regional Rural Banks set up, the first being Prathama Bank at Moradabad |
| 1980 | Six more banks nationalised |
| 1982 | NABARD established for rural and agricultural refinance |
| 1990 | Small Industries Development Bank of India begins work |
| 1991 and 1998 | Narasimham Committee reports on banking sector reform |
The mergers
| Effective from | Banks merged | Into |
|---|---|---|
| 1993 | New Bank of India | Punjab National Bank |
| 2004 | Global Trust Bank | Oriental Bank of Commerce |
| 1 April 2017 | Five associate banks and Bharatiya Mahila Bank | State Bank of India |
| 1 April 2019 | Vijaya Bank and Dena Bank | Bank of Baroda |
| 1 April 2020 | Oriental Bank of Commerce and United Bank of India | Punjab National Bank |
| 1 April 2020 | Syndicate Bank | Canara Bank |
| 1 April 2020 | Andhra Bank and Corporation Bank | Union Bank of India |
| 1 April 2020 | Allahabad Bank | Indian Bank |
The merger of New Bank of India with Punjab National Bank in 1993 was the first amalgamation of two nationalised banks. The 2017 round brought the State Bank of Bikaner and Jaipur, Hyderabad, Mysore, Patiala and Travancore, along with Bharatiya Mahila Bank, into the State Bank of India. The round that took effect on 1 April 2020 was the largest: four anchor banks absorbed six others and the number of public sector banks came down from twenty-seven in 2017 to twelve.
The law and the private side
- Voluntary amalgamation of two banking companies is sanctioned by the Reserve Bank under Section 44A of the Banking Regulation Act, 1949.
- Section 45 of the same Act lets the Reserve Bank seek a moratorium and place a scheme of compulsory amalgamation for a failing bank before the central government.
- Private banks have merged on the same pattern: Centurion Bank of Punjab into HDFC Bank in 2008, Bank of Rajasthan into ICICI Bank in 2010, ING Vysya into Kotak Mahindra Bank in 2015, and Lakshmi Vilas Bank into DBS Bank India in 2020.
- IDBI Bank was reclassified as a private sector bank in 2019 after the Life Insurance Corporation acquired a majority stake in it.
- HDFC Limited, the housing finance company, was merged into HDFC Bank in 2023, the largest merger in Indian corporate history at the time.
Exam Point of View
Banking papers ask this topic as dates, numbers and pairings. Learn the four dates first: 1935, 1949, 1955 and 1969. Learn the two rounds as pairs, fourteen banks at fifty crore rupees in 1969 and six banks at two hundred crore rupees in 1980, because papers give one half and ask the other. Then learn the merger map of 2020: Oriental Bank of Commerce and United Bank of India into Punjab National Bank, Syndicate Bank into Canara Bank, Andhra Bank and Corporation Bank into Union Bank of India, and Allahabad Bank into Indian Bank. Also expected are the sections of the Banking Regulation Act, 1949 on amalgamation, and the Cooper case. The commonest trap is the number twenty, the total of the two rounds, offered as the answer for 1969.

Read the full explanation →Frequently Asked Questions
Why were banks nationalised in 1969?
Private banks lent mainly to large industry and trade, and branches were concentrated in cities. Nationalisation was meant to bring banking to rural and semi-urban areas and to direct credit to agriculture, small industry, exports and the weaker sections, which was later formalised as priority sector lending.
Which bank is the oldest public sector bank in India?
Allahabad Bank, founded in 1865, was the oldest joint stock bank in the country and was nationalised in 1969, but it ceased to exist as a separate bank when it was merged into Indian Bank in 2020. Among the banks working today, Punjab National Bank, founded in 1894, is the oldest swadeshi bank.
How many public sector banks are there after the 2020 merger?
The amalgamation notified with effect from 1 April 2020 reduced the number of public sector banks from twenty-seven in 2017 to twelve, made up of the State Bank of India and eleven nationalised banks. Any later change would come through a fresh government notification.
Under which law are two banks amalgamated?
A voluntary amalgamation of two banking companies is approved by the Reserve Bank under Section 44A of the Banking Regulation Act, 1949. For a failing bank, Section 45 lets the Reserve Bank seek a moratorium and place a compulsory scheme of amalgamation before the central government, as was done for Global Trust Bank and Lakshmi Vilas Bank.
