New Delhi, Aug 30 (PTI) - In the biggest consolidation exercise in the banking space, the government on Friday announced four major mergers of public sector banks, bringing down their total number to 12 from 27 in 2017, a move aimed at making state-owned lenders global sized banks.

United Bank of India and Oriental Bank of Commerce will be merged with Punjab National Bank, making the proposed entity the second largest public sector bank (PSB).

Making the announcements, Finance Minister Nirmala Sitharaman said Syndicate Bank will be merged with Canara Bank, while Allahabad Bank will be amalgamated with Indian Bank.

Similarly, Andhra Bank and Corporation Bank will be consolidated with Union Bank of India.

In place of fragmented lending capacity with 27 PSBs in 2017, now there will be only 12 state-run banks post consolidation, Sitharaman said.

The finance minister also said banks will be provided adequate capital.

Last week, she had announced that the ₹ 70,000 crore capital infusion for PSBs for the current fiscal would be front-loaded.

Financial Services Secretary Rajiv Kumar, who was also present at the press conference, said there was no retrenchment in the past consolidations, including of SBI, and service conditions of employees improved.

"Employees will only benefit with the mergers," he added.

Earlier this year, Dena Bank and Vijaya Bank were merged with Bank of Baroda. Prior to this, the government had merged five associate banks of SBI and Bharatiya Mahila Bank with the State Bank of India.

Indian Overseas Bank, UCO Bank, Bank of Maharashtra and Punjab and Sind Bank will continue to function as earlier as they have strong "regional focus", Sitharaman added.

Post the consolidation announced on Friday, Punjab National Bank will have business size of ₹ 17.94 lakh crore, becoming the second largest PSB after SBI with a business of ₹ 52.05 lakh crore.

The consolidated Canara Bank will be the fourth largest bank with business of ₹ 15.2 lakh crore, followed by Union Bank of India at ₹ 14.59 lakh crore.

After subsuming Allahabad Bank, Indian Bank will be the seventh largest state-lender with business size of ₹ 8.08 lakh crore.

Bank of Baroda, after the merger with Vijaya Bank and Dena Bank, had become the country's third largest bank. It has a business of ₹ 16.13 lakh crore.

Bank consolidation creates larger state-owned lenders, merging several public sector banks to strengthen capital and scale. The government announced a major bank consolidation reducing public sector banks from twenty-seven to twelve by merging specified banks-United Bank of India and Oriental Bank of Commerce into Punjab National Bank; Syndicate Bank into Canara Bank; Allahabad Bank into Indian Bank; Andhra Bank and Corporation Bank into Union Bank of India-to concentrate lending capacity, create larger state-owned lenders and enhance scale and competitiveness.
