A bank merger is the process in which two or more banks combine their assets, liabilities, operations and resources to form a single banking entity.
In the case of Public Sector Banks (PSBs), mergers are generally aimed at creating larger, stronger and more efficient banks with greater financial capacity and wider operational reach.
Evolution of Bank Merger in India
The idea of bank consolidation has been discussed for several decades.
Second Narasimham Committee (1998)
The committee recommended a three-tier banking structure:
- 3 large banks with international presence.
- 8–10 national banks.
- A larger number of regional and local banks.
PJ Nayak Committee (2014)
The committee recommended reforms in the ownership and governance of PSBs, including consolidation and greater managerial autonomy.
Major Bank Mergers in India
| Year | Merger/Consolidation |
| 2017 | Five SBI associate banks merged with SBI |
| 2017 | Bharatiya Mahila Bank merged with SBI |
| 2019–20 | 10 nationalised banks consolidated into 4 larger banks |
| 2020 | Number of PSBs reduced to 12 |
The government also pursued the consolidation of Regional Rural Banks (RRBs) in different phases.
Why are Bank Mergers Needed?
Bank consolidation is mainly intended to improve the strength, efficiency and competitiveness of the banking sector.
- Strengthening weak banks: Stronger institutions can provide financial and managerial support to weaker banks.
- Creating globally competitive banks: Larger banks have greater balance-sheet capacity to compete internationally.
- Meeting Basel requirements: A stronger capital base helps banks meet regulatory capital requirements.
- Managing NPAs: Consolidation can strengthen the capacity of banks to deal with stressed assets.
- Diversifying risk: Larger banks can maintain more diversified loan portfolios.
- Supporting economic growth: Stronger banks can potentially provide greater credit to productive sectors.

Benefits of Bank Mergers
Economies of Scale
A larger customer base and wider branch network can help reduce duplication and improve cost efficiency.
Better Resource Utilisation
Merged banks can combine their branch networks, technology, human resources, customer base and infrastructure, improving overall resource utilisation.
Greater Financial Strength
Larger balance sheets can improve the ability of banks to absorb financial shocks and meet growing credit demand.
Improved Operational Efficiency
A smaller number of larger PSBs can make capital allocation, performance monitoring and strategic planning easier.
Wider Range of Services
Merged institutions can combine their strengths and provide customers with a broader range of banking products and services.
Greater Global Competitiveness
Larger banks may have greater capacity to raise funds, expand operations and compete in international markets.
Challenges of Bank Mergers
Transfer of Existing Weaknesses
A merger does not automatically eliminate the problems of a weaker bank. NPAs, operational weaknesses and other financial stress may be transferred to the merged entity.
Human Resource Issues
Differences in organisational culture, work practices, transfer policies and employee expectations can make integration difficult.
Customer-Related Concerns
Customers may initially face uncertainty regarding branches, account processes, technology platforms and service arrangements.
Risk of Excessive Concentration
Very large banks may gain greater market power, potentially reducing competition and affecting attention to local and smaller borrowers.
Merger Does Not Automatically Solve NPAs
Simply combining two balance sheets cannot resolve bad loans. Effective credit appraisal, monitoring and recovery mechanisms remain essential.
Way Forward
Bank consolidation should be accompanied by wider reforms in the banking sector.
- Strengthen corporate governance in PSBs.
- Improve credit appraisal and risk management.
- Ensure timely recognition and recovery of NPAs.
- Provide greater operational autonomy to bank management.
- Improve technology and customer service.
- Strengthen human-resource and organisational integration.
- Ensure that larger banks continue serving small, local and underserved borrowers.
Conclusion
Bank mergers can help create larger, stronger and more efficient banks, but size alone cannot guarantee a healthy banking system.
The success of consolidation ultimately depends on good governance, sound lending practices, effective risk management and efficient NPA recovery.
Therefore, bank mergers should be treated as one component of broader banking-sector reforms, rather than as a standalone solution.
