On the merger in the public sector banks, Subramanian said they are being done based on synergies, and policy is to exploit economies of scale.

As part of consolidation exercise, erstwhile Vijaya Bank and Dena Bank were merged with Bank of Baroda (BoB) effective April 1 to create the third-largest lender of the country.
The maiden three-way amalgamation is the first step in the consolidation of the public sector banking industry, recommended in 1991 by the Narasimham Committee report. Through this merger, the government has created an institution of global scale and size, thereby providing significant benefit to all stakeholders.
The consolidated entity started the operation with a business mix of over Rs 15 lakh crore on the balance sheet, with deposits and advances of Rs 8.75 lakh crore and Rs 6.25 lakh crore, respectively.
BoB, the second-largest public sector lender after State Bank of India, now has over 9,500 branches, 13,400 ATMs, and 85,000 employees to serve 12 crore customers.
Prior to the BoB merger, the government only had experience of State Bank of India which had merged five of its associate banks -- State Bank of Patiala, State Bank of Bikaner and Jaipur, State Bank of Mysore, State Bank of Travancore and State Bank of Hyderabad and also Bhartiya Mahila, effective April 2017.
