T homas Wu is a Taiwanese billionaire and the chairman of Taishin Financial Holdings, a major financial services group in Taiwan. He is a member of the powerful and influential Wu family, which has been a dominant force in Taiwanese business for generations. His father, the late Wu Ho-su, was the patriarch who built the family's initial empire. After his father's death, the family's assets were divided among his sons.

Thomas took control of the family's financial services assets and founded Taishin Financial Holdings in 2001. He has since built it into a major player in the Taiwanese market, with a key subsidiary in Taishin International Bank, as well as businesses in securities and insurance. His career has been marked by a long and often contentious battle to gain full control of another major financial institution, Chang Hwa Bank, a fight that has involved years of legal and political maneuvering. His wealth is derived from his family's substantial stake in the publicly traded Taishin Financial Holdings.
