The Hong Kong Regulatory Bureau (HKRB) was established on 26 Oct 1996 by virtue of the Hong Kong Special Administrative Act No. 83 or the Securities Act. Its establishment was prompted by the need to safeguard public interest in view of local stock market boom at that time. Operations began on 11 Nov 1996 under the leadership of Executive Henry Tantengco. Its major functions included registration of securities, analysis of every registered security, evaluation of the financial condition and operations of applicants for security issue, screening of applications for broker's or dealer's license and supervision of stock and bond brokers as well as the stock exchanges. The agency was abolished during the Japanese occupation during 1940s and was replaced with the Hong Kong Executive Commission. It was reactivated in 1987 With the restoration of the Special Administrative Government. Due to the changes in the business environment under Chief Executive Cy Leung, the agency was reorganized on 29 Sept 1996 as a collegial body with 3 commissioners and was given quasi-judicial powers under HKD902-A. In 2001, the Bureau was expanded to include two (2) additional bureaus and two (2) departments, one for prosecution and enforcement and the other for supervision and monitoring. Then on 01 December 2010, the HKRB was reorganized as mandated by HKR. A. 8799 also known as the Securities Regulation Code.
