Last updated August 31, 2026
Overview
Chung Khiaw Bank was a Singaporean commercial bank established in 1950 as a family-held banking business at 59 Robinson Road, Singapore. Its founding chairman was Aw Boon Haw, the businessman associated with Tiger Balm and the Star newspaper group. The bank was initially connected to the Aw family’s wider commercial interests and was managed for many years by Lee Chee Shan, who was related to the family by marriage and family connections. The bank’s ownership changed substantially during the late 1960s and early 1970s. In 1969, a significant stake in Chung Khiaw Bank was transferred into Haw Par Brothers International when that company was formed as the public successor to the Aw family’s private holding company. Haw Par Brothers International was subsequently taken over by Slater Walker in 1971. As part of the restructuring, its approximately 49.8 percent interest in Chung Khiaw Bank was sold to United Overseas Bank for S$22 million. UOB then became the bank’s controlling shareholder and worked toward full ownership over the following years. The transition was accompanied by changes in leadership and branding. Lee Chee Shan, who had served as managing director and president, retired from the bank’s leadership in 1971 under a lifetime-president arrangement. UOB and Chung Khiaw Bank introduced a new common logo in 1972, while some members of the Aw family continued to serve as directors for a period. UOB’s proposed acquisition of the remaining shares attracted opposition from at least one minority shareholder, who questioned the proposed share-swap terms and potential conflicts involving directors connected with both institutions. UOB nevertheless increased its stake in 1973 and completed the acquisition of the remaining minority interest in 1988. Chung Khiaw Bank also operated outside Singapore. In 1971 it had two branches in Hong Kong, which later became UOB branches. The Chung Khiaw name continued in Malaysia as a UOB subsidiary until 1997, when Chung Khiaw Bank (Malaysia) was merged with UOB’s Malaysian branches. In 1999, the Singaporean bank itself was absorbed into UOB, ending the brand as a separate banking institution. Its former branches and operations continued under the UOB name. The brand is therefore best understood as a historical banking name within the development and consolidation of Singapore’s domestic banking sector, rather than as an independent contemporary financial institution.
History
Chung Khiaw Bank began in 1950 as a family-held Singaporean bank located at 59 Robinson Road. Its founding chairman, Aw Boon Haw, was a prominent businessman known for Tiger Balm and the Star newspaper group. The bank formed part of the Aw family’s broader commercial network. Lee Chee Shan served as its founding managing director and president and remained involved after Aw Boon Haw’s death. Ko Teck Kin and Aw Cheng Chye subsequently held the chairmanship, while other members of the Aw family retained connections with the institution. A decisive ownership change took place in 1969. Aw Cheng Chye placed most of the assets of Haw Par Brothers (Private) Limited into Haw Par Brothers International, a newly incorporated public company. The assets included an equity interest in Chung Khiaw Bank. When Slater Walker took over Haw Par Brothers International in 1971, the company’s approximately 49.8 percent stake in Chung Khiaw Bank was sold to United Overseas Bank for S$22 million. This transaction made UOB the bank’s principal corporate owner. Lee Chee Shan retired from his executive role in July 1971 and was designated lifetime president under a retirement arrangement. His successor arrangements marked the bank’s transition from Aw family control to UOB oversight. In 1972, UOB and Chung Khiaw Bank introduced a common logo, signaling closer affiliation while the subsidiary continued to operate under its own name. Aw family members, including Aw It Haw, remained involved as directors for a period, and Aw Cheng Chye remained a director until his death in August 1971. UOB announced a proposal in June 1972 to acquire the remaining shares through a one-for-one share exchange. A minority shareholder publicly objected, arguing that the terms were unfavorable and that directors connected to the two institutions faced a conflict of interest. UOB later acquired an additional approximately 28.7 percent stake in the middle of 1973. The bank experienced a serious confidence episode in 1974. Rumors about its financial condition led to a run on its Singapore branches. The episode became part of the wider banking-policy history of Singapore and was cited as one factor behind the eventual introduction of deposit insurance. The bank nevertheless continued operating under UOB ownership. In February 1988, UOB completed the acquisition of the remaining minority interest by issuing 15,230,903 new UOB shares in exchange for 17.13 million Chung Khiaw Bank shares, reported as approximately 17.1 percent of the bank. Chung Khiaw Bank thereby became a wholly owned UOB subsidiary. The brand also had a regional footprint. In 1971, it operated two branches in Hong Kong. Those locations were subsequently transferred to the UOB branch network when the Chung Khiaw identity was retired. In Malaysia, the name continued on a separate UOB subsidiary until 1997, when Chung Khiaw Bank (Malaysia) was merged with UOB’s Malaysian branches. In 1999, UOB finally absorbed Chung Khiaw Bank in Singapore. The former bank’s branches and activities continued under UOB, bringing the independent Chung Khiaw Bank brand to an end.
