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.
By GK24 Editorial Team· Published · 4 min read

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.

Practice MCQs on this topic
In which year was the State Bank of India created following the passage of the Imperial Bank of India into state ownership?
- A.1947
- B.1965
- C.1955
- D.1950
Show answer
Correct answer: C. 1955
Explanation
The correct answer is C, 1955. The All India Rural Credit Survey Committee found that rural credit needed a bank with a nationwide branch network, so Parliament passed the State Bank of India Act, 1955, and the Imperial Bank of India was taken over and renamed the State Bank of India with effect from 1 July 1955. The Imperial Bank itself had been formed in 1921 by joining the presidency banks of Bengal, Bombay and Madras.
Option A, 1947, is the year of independence and of no banking statute of this kind. Option B, 1965, is far too late; by then the State Bank already had its associate banks under the Act of 1959. Option D, 1950, is the year the Constitution came into force, and candidates pick it by association. Note also that 1949 was the year the Reserve Bank was nationalised, which is a different event from the creation of the State Bank.
Small Industries Development Bank of India (SIDBI) was established in which year?
- A.1990
- B.1988
- C.1992
- D.1994
Show answer
Correct answer: A. 1990
Explanation
The correct answer is A, 1990. SIDBI was set up under the Small Industries Development Bank of India Act, 1989 and began operations in 1990 as the principal financial institution for the promotion, financing and development of micro, small and medium enterprises. It started as a subsidiary of IDBI and its head office is at Lucknow, which is itself a frequently asked detail.
Option B, 1988, is the year before the Act and is a common trap. Option C, 1992, is the year the Securities and Exchange Board of India became a statutory body, and Option D, 1994, is the year the first new generation private banks were licensed after the Narasimham Committee report. Keeping the development institutions in order helps: NABARD in 1982, SIDBI in 1990, and the National Housing Bank in 1988, each set up by its own Act of Parliament.
How many commercial banks were nationalised in the first round on 19 July 1969?
- A.Six
- B.Eight
- C.Fourteen
- D.Twenty
Show answer
Correct answer: C. Fourteen
Explanation
The correct answer is C, Fourteen. On 19 July 1969 the government promulgated an ordinance nationalising fourteen major commercial banks, each of which held deposits of fifty crore rupees or more. The list included Central Bank of India, Bank of India, Punjab National Bank, Bank of Baroda, Canara Bank, Union Bank of India, Allahabad Bank, Indian Bank, Indian Overseas Bank, Syndicate Bank, Dena Bank, United Bank of India, United Commercial Bank and Bank of Maharashtra.
Option A, six, is the number nationalised in the second round of 15 April 1980. Option B, eight, matches no round, although the State Bank group once had seven associate banks. Option D, twenty, is the sum of the two rounds, fourteen plus six, and is the distractor that catches most candidates. Remember the pairs as fourteen in 1969 with fifty crore rupees, and six in 1980 with two hundred crore rupees.
In the second round of bank nationalisation in April 1980, how many banks were nationalised?
- A.Four
- B.Six
- C.Seven
- D.Eleven
Show answer
Correct answer: B. Six
Explanation
The correct answer is B, Six. On 15 April 1980 six private banks whose deposits were 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. With these, public ownership covered the greater part of bank deposits in the country.
Option A, four, is the number of anchor banks in the amalgamation that took effect on 1 April 2020. Option C, seven, was the number of associate banks of the State Bank of India under the Act of 1959. Option D, eleven, matches no event in this sequence. Note that five of these six banks were themselves later merged away: New Bank of India into Punjab National Bank, Vijaya Bank into Bank of Baroda, Oriental Bank of Commerce into Punjab National Bank, and Andhra Bank with Corporation Bank into Union Bank of India.
The Reserve Bank of India was nationalised with effect from:
- A.1 April 1935
- B.1 January 1949
- C.1 July 1955
- D.19 July 1969
Show answer
Correct answer: B. 1 January 1949
Explanation
The correct answer is B, 1 January 1949. The Reserve Bank of India began as a shareholders' institution in 1935 and was taken into full government ownership from 1 January 1949 under the Reserve Bank of India (Transfer to Public Ownership) Act, 1948. From that date the entire share capital of the central bank has been held by the Union government.
Option A, 1 April 1935, is the day the Reserve Bank began operations under the RBI Act, 1934, following the recommendation of the Hilton Young Commission, but it was then privately held. Option C, 1 July 1955, is the day the Imperial Bank became the State Bank of India. Option D, 19 July 1969, is the date of the first round of commercial bank nationalisation. All four dates belong to this topic, which is why the question is set as a list of them.
Which bank was merged with Punjab National Bank in 1993, in the first merger of two nationalised banks?
- A.New Bank of India
- B.Oriental Bank of Commerce
- C.United Bank of India
- D.Nedungadi Bank
Show answer
Correct answer: A. New Bank of India
Explanation
The correct answer is A, New Bank of India. New Bank of India, one of the six banks nationalised in 1980, ran into heavy losses and was amalgamated with Punjab National Bank in 1993. It was the first time one nationalised bank was merged into another, and for years it stood alone as an example of consolidation in the public sector.
Option B, Oriental Bank of Commerce, was indeed merged into Punjab National Bank, but in the round that took effect on 1 April 2020, not in 1993. Option C, United Bank of India, was merged into Punjab National Bank in that same 2020 round. Option D, Nedungadi Bank, was a small private bank of Kerala that was merged into Punjab National Bank in 2003. All three wrong options did eventually join Punjab National Bank, so only the year decides the answer.
In the amalgamation that took effect on 1 April 2020, Syndicate Bank was merged into which bank?
- A.Canara Bank
- B.Union Bank of India
- C.Indian Bank
- D.Bank of Baroda
Show answer
Correct answer: A. Canara Bank
Explanation
The correct answer is A, Canara Bank. Under the amalgamation notified with effect from 1 April 2020, Syndicate Bank was merged into Canara Bank. Both banks had their roots in coastal Karnataka, Canara Bank at Mangaluru and Syndicate Bank at Udupi, so the merged bank kept a strong base in the same region.
Option B, Union Bank of India, absorbed Andhra Bank and Corporation Bank in the same round. Option C, Indian Bank, absorbed Allahabad Bank. Option D, Bank of Baroda, had already absorbed Vijaya Bank and Dena Bank a year earlier, from 1 April 2019. The four anchor banks of the 2020 round were Punjab National Bank, Canara Bank, Union Bank of India and Indian Bank, and remembering which six banks went into which of the four is the whole of this question.
Allahabad Bank, the oldest joint stock bank in India, was merged into which bank in 2020?
- A.Punjab National Bank
- B.Indian Bank
- C.Canara Bank
- D.Bank of India
Show answer
Correct answer: B. Indian Bank
Explanation
The correct answer is B, Indian Bank. Allahabad Bank, founded in 1865 and one of the fourteen banks nationalised in 1969, was amalgamated into Indian Bank with effect from 1 April 2020. Indian Bank, founded in 1907 at Madras, was the anchor bank, so the older institution disappeared into the younger one, which is the detail examiners like about this pair.
Option A, Punjab National Bank, absorbed Oriental Bank of Commerce and United Bank of India in the same round. Option C, Canara Bank, absorbed Syndicate Bank. Option D, Bank of India, was not an anchor bank in this round at all and continues as a separate public sector bank. After this round the number of public sector banks came down from twenty-seven in 2017 to twelve.
Vijaya Bank and Dena Bank were amalgamated with which bank with effect from 1 April 2019?
- A.Punjab National Bank
- B.Bank of Baroda
- C.Union Bank of India
- D.State Bank of India
Show answer
Correct answer: B. Bank of Baroda
Explanation
The correct answer is B, Bank of Baroda. With effect from 1 April 2019, Vijaya Bank of Karnataka and Dena Bank of Gujarat were merged into Bank of Baroda. It was the first three way amalgamation of public sector banks in India, and the merged entity became one of the largest public sector banks by branch network.
Option A, Punjab National Bank, took in Oriental Bank of Commerce and United Bank of India a year later. Option C, Union Bank of India, took in Andhra Bank and Corporation Bank in the same 2020 round. Option D, State Bank of India, had completed its own merger in 2017 by absorbing five associate banks and Bharatiya Mahila Bank. Note that Dena Bank was one of the fourteen banks of 1969 and Vijaya Bank one of the six of 1980.
The banks nationalised on 19 July 1969 were those holding deposits of at least:
- A.Rupees 25 crore
- B.Rupees 50 crore
- C.Rupees 100 crore
- D.Rupees 200 crore
Show answer
Correct answer: B. Rupees 50 crore
Explanation
The correct answer is B, Rupees 50 crore. The cut off used in the first round of nationalisation was deposits of fifty crore rupees or more as on the relevant date, and fourteen banks crossed it. The purpose stated in the preamble was to control the commanding heights of the economy and to direct credit to agriculture, small industry, exports and the weaker sections.
Option A, twenty-five crore rupees, matches no round. Option C, one hundred crore rupees, is a figure candidates invent as a midpoint. Option D, two hundred crore rupees, is the threshold of the second round in 1980, when six banks were nationalised. The pair to memorise is fifty crore rupees with fourteen banks in 1969 and two hundred crore rupees with six banks in 1980; papers often give the year and ask the amount, or give the amount and ask the number.
Rustom Cavasjee Cooper v. Union of India, decided by the Supreme Court in 1970, is known as the:
- A.Privy Purse case
- B.Bank Nationalisation case
- C.Fundamental Rights case
- D.Judges Transfer case
Show answer
Correct answer: B. Bank Nationalisation case
Explanation
The correct answer is B, the Bank Nationalisation case. R. C. Cooper, a shareholder and director of one of the affected banks, challenged the law of 1969, and an eleven judge bench of the Supreme Court struck it down because the compensation provided for the acquired undertakings was not adequate and the banks were barred from carrying on business. Parliament then enacted a fresh law, so nationalisation stood.
Option A, the Privy Purse case, is Madhav Rao Scindia v. Union of India, about the derecognition of the princes. Option C, the Fundamental Rights case, is Kesavananda Bharati v. State of Kerala of 1973, which laid down the basic structure doctrine. Option D, the Judges Transfer case, is S. P. Gupta v. Union of India. All four are landmark cases of the same period, which is why they appear together as options.
Which of the following was merged into the State Bank of India with effect from 1 April 2017?
- A.Bharatiya Mahila Bank
- B.Dena Bank
- C.Corporation Bank
- D.United Bank of India
Show answer
Correct answer: A. Bharatiya Mahila Bank
Explanation
The correct answer is A, Bharatiya Mahila Bank. From 1 April 2017 the State Bank of India absorbed its five remaining associate banks, the State Bank of Bikaner and Jaipur, the State Bank of Hyderabad, the State Bank of Mysore, the State Bank of Patiala and the State Bank of Travancore, together with Bharatiya Mahila Bank, which had been set up in 2013 as a bank focused on women customers.
Option B, Dena Bank, was merged into Bank of Baroda in 2019. Option C, Corporation Bank, went into Union Bank of India in 2020. Option D, United Bank of India, went into Punjab National Bank in 2020. Note that two associate banks had been merged into the State Bank earlier, the State Bank of Saurashtra in 2008 and the State Bank of Indore in 2010, which is why only five were left in 2017.
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.
