The Central Moneymarkets Unit (CMU) was established in 1990 to provide computerised clearing and settlement facilities for Exchange Fund Bills and Notes. In December 1993, the HKMA extended the service to other Hong Kong dollar debt securities. The CMU offers an efficient, safe and convenient clearing and custodian system for Hong Kong dollar debt instruments. The CMU service was further extended to non-Hong Kong dollar debt securities in January 1996. Over the years, the CMU has evolved to become the clearing and settlement system in Hong Kong for debt securities denominated in Hong Kong dollars and other major currencies, facilitating the bond market development in Hong Kong.
Today, the CMU has developed various external links with regional and international central securities depositories (CSDs) for a broader service coverage. Beyond settling debt securities, the CMU now also offers an extensive range of post-trade and debt issuance services, providing members a secure and efficient system across borders.

The CMU is a member of the Asia-Pacific Central Securities Depository Group (ACG) since 2001. In 2024, the CMU joined the International Securities Services Association (ISSA) as a member organisation of the Board of Directors.
