W ee Ee Cheong is a Singaporean billionaire and the patriarch of the Wee family, which controls the United Overseas Bank (UOB), one of Singapore's largest and most important banks. He is the eldest son of the late banking titan Wee Cho Yaw, who served as the bank's chairman for decades and built it into a major regional financial services group. The bank was founded by his grandfather, Wee Kheng Chiang. After his father's death, Wee Ee Cheong, along with his two siblings, inherited the family's vast fortune and their controlling stake in the bank.

Wee Ee Cheong has been deeply involved in the family's business for his entire career. He has served as the CEO and deputy chairman of UOB since 2007, taking over the day-to-day leadership from his father. As CEO, he has been responsible for steering the bank's strategy, navigating it through the global financial crisis, and overseeing its continued expansion across Southeast Asia. He is now the public face of the third generation of one of Singapore's most powerful and enduring banking dynasties.
