The organizational structure of the financial group to be formed in April through the integration of Sanwa Bank, Tokai Bank and Asahi Bank will be finalized by September, Sanwa Bank President Kaneo Muromachi said in a recent interview.

Muromachi said executives of what would be the second-largest banking group in the world are ironing out differences in business strategies the three city banks use.

"Before we decide on our future organizational structure, we must first decide what business strategies we will take," the 61-year-old top official of the major city bank said. "We need to coordinate the trio's business strategies in areas ranging from banking for individuals and small and midsize corporations, as well as operations for large firms and those overseas."
