The Reserve Bank of India (RBI) has given the green light to Saraswat Co-operative Bank, India's largest co-operative bank, to merge New India Co-operative Bank (NICBL) with itself. The merger will take effect from August 4. Saraswat Bank will absorb all assets, liabilities, and customers of NICBL from that date. Though top officials at Saraswat Bank refused to speak on the matter, the move puts into relief what such mergers will do to ordinary bank customers.
