Dubai: State Bank of Travancore (SBT) has said it is in the process of expanding its branch network units across Kerala and other metro cities. The bank plans to add more than 100 branches, including NRI-specific centres, over the next 12 months to its existing 880 units spread across the country, SBT Managing Director, P. Nanda Kumaran, said. The bank is expected to reach a branch network to more than 1,000 units soon, he said. The bank seeks to diversify products and services by foraying into gold bullion trade, he added. "Our target is to become one of the top ten banks in India within five-six years," Kumaran said. The SBT chief, who is on a visit to the UAE, said the bank has achieved a 28 percent growth in its NRI business in the last fiscal, partly due to an increase in interest rates following the deregulation of interest rates for NRE term deposits. SBT, a subsidiary of State Bank of India, recorded 24 percent growth in business that includes deposits and advances in 2011-2012 to 1,300 billion ($26 billion). The NRI segment accounts for 21 percent of the bank's total deposits while one-third of all overseas remittances to Kerala are through the bank. The lender also accounts for one-third of NRI deposits within the state, he said. The bank has set up a representative office in Dubai and manages City Exchange.
