CITYSTATE SAVINGS BANK was granted the license to operate as a thrift bank by the Bangko Sentral ng Pilipinas on August 7, 1997 and formally opened its banking doors to the public on August 8, 1997 with its first branch in Chino Roces Avenue, Makati City forging a solid partnership between a team of Filipino businessmen and a prominent Singaporean investment holding company. At present, the Bank's principal and administrative offices are located at Citystate Centre Building along Shaw Boulevard in Pasig City, Metro Manila.

Presently, Citystate Savings Bank has 24 branches in key cities and municipalities strategically located within Metro Manila and provincial areas; nineteen (19) in Metro Manila and four (4) provincial branches in Meycauyan, Baliuag, Plaridel and Cebu. This is part of the bank’s commitment to pursue an aggressive branch expansion to open 38 to 50 branches within the next three (3) years to cater to small and medium enterprises. To complement this expansion program, the bank pursued an aggressive ATM rollout program significantly in places with high pedestrian traffic inside malls and nearby transport terminals.

In the midst of the growing economy Citystate Savings Bank was formally listed at the Philippine Stock Exchange on January 2, 2002. This resulted to even greater heights as the performance of the bank increased dramatically with definite plans of expansion in terms of setting up more branches complemented with the development of new products and enhanced services. As a result, in October 2005, Citystate successfully ventured into a stock rights offer of P22 Million common shares which increased its capitalization to P670 Million from P450 Million.

In November 2006, Citystate Bank obtained its Trust and Foreign Currency Deposit license from the Bangko Sentral ng Pilipinas to accept dollar and other foreign currency denominated deposits and manages funds, securities, and properties for the benefit and advantage of the clients.
