Tsai Hong-tu is a Taiwanese lawyer, banker and businessman who chairs Cathay Financial Holdings, one of Taiwan's leading financial services companies.

He earned a law degree from National Taiwan University in 1974, then went to the United States, where he completed a Juris Doctor and a PhD at Southern Methodist University in 1978.

Where Tsai Hong-tu's money comes from

Tsai's wealth comes from his family's stake in Cathay Financial Holdings. When his father died in 2004, Hong-tu and his brothers Tsai Cheng-da and T.Y. Tsai inherited stakes in the company. All three brothers are billionaires, as are their cousins Richard and Daniel Tsai, so the Tsai family counts several billionaires across two branches.

Cathay's business spans financial services in Taiwan, and the family also controls Cathay Real Estate, a property developer. Tsai has been known for giving as well. In 2010 Forbes listed him among the world's most altruistic people after he donated $3 million toward Typhoon Morakot relief and gave $7.8 million to National Taiwan University's law school in 2003.
