The National Clearing House was established in 1994 by the National Bank of Cambodia to enable banks to clear and settle the interbank obligations arising from business transactions of economic agents. The National Clearing System (NCS) is operated by the National Clearing House, which is located on the premises of the NBC. The NCS has been continuously modernized in order to improve the security of the system in line with technology advancement, provide more convenience to the participants, and to enhance the capacity for clearing consistent with the development of the banking sector and economy. The NCS was enhanced to an automated system and launched in December 2012, which is capable of centrally clearing interbank payment transactions by checks and electronic payment orders, namely Direct Credit, Direct Debit and Credit Remittance, denominated in USD and KHR.

The NBC also provides the check exchange center for participants to exchange physical checks. Besides the check exchange centers located in the National Clearing House, there are currently four check exchange centers at the NBC’s provincial branches in Siem Reap, Kampong Som, Kampong Cham, and Battambang and will be extended to another two provinces namely Svay Rieng and Banteay Meanchey soon.
