YES Bank is working on a plan to re-balance its business model by broad-basing the portfolio towards retail banking. Group president and country head of the bank Amit Kumar said over a period of time, the bank is getting equally focused on SMEs and retail banking directionally and it wants to see its business portfolio coming 33% each from large corporates, mid-segments and SMEs. The bank, which has taken its balance sheet size to over Rs 1,00,000 crore, depends on large corporates for 66% of its business. About 15% of its portfolio comprises the mid-segment and 17% belongs to small and medium enterprises (SMEs). The bank also wants to re-balance its resources of deposits. It gets about 20% of its deposits from CASA. Kumar said the bank would wish to take CASA to 35-40% in the next 12-18 months. For its deposits mobilisation, Yes Bank has also tapped cost effective foreign currency resources. In all, the bank has managed to raise $400 million in different tranches of the swap window recently provided by the Reserve Bank.
