Proposed Merger
The proposed merger of the State Bank of India with its five associate banks and the Bharatiya Mahila Bank may pose several benefits.

1. The increased balance sheet size will enable the bank to obtain better pricing on both internationally sourced funds and domestic deposits, thus helping it lower lending rates and improve profitability. 
2. The added branch network and customer base will also help it expand reach and enable the lender to rationalise resources across the board. 
3. There are various estimates of the potential cost savings, with one projection putting the possible reduction in cost-to-income ratio at 1 percentage point. 
4. The lender’s increased size, in terms of assets, will also give it the requisite muscle to take on new competition from larger banking entities that are likely to be created by consolidation in the banking industry. 
5. The Bank Board Bureau has been tasked with overseeing a restructuring among public sector banks in keeping with the government’s aim of reducing the number of state-owned lenders and improving their financial health.

Challenges from merger
The merger will, however, pose its unique set of challenges. 
1.  The scale of the task is substantial given the total staff strength. With more than two lakh employees, the parent will add close to one-fifth that number by way of additions posing a huge test in terms of integration of roles, salary, perquisite and pension structures and, no less importantly, work cultures. 
2.  Much of the opposition from the bank unions stems from concerns relating to these issues. Customers of the smaller, community or regional market-focussed subsidiaries such as the State Bank of Travancore may be discomfited by having to deal with a larger, more impersonal lender, one where the size of their accounts may be viewed as comparatively marginal. For regulators, the new entity will throw up interesting oversight issues.
3.  Already identified by the Reserve Bank of India as the country’s key Domestic Systemically Important Bank, or too big to fail in simple terms, the enlarged SBI’s capital adequacy norms will climb and may require far more by way of infusion of funds than the Centre has committed so far. 

But such challenges must not be used to undermine the obvious benefits of merger.
