Clearing House Automated Transfer System

The Clearing House Automated Transfer System, or CHATS, is a Real Time Gross Settlement (RTGS) system for the transfer of funds in Hong Kong. It is operated by Hong Kong Interbank Clearing Limited, a private company jointly owned by the Hong Kong Monetary Authority (HKMA) and the Hong Kong Association of Banks. Transactions in four currency denominations may be settled using CHATS: Hong Kong dollar, renminbi, euro, and US dollar. In 2005, the value of Hong Kong dollar CHATS transactions averaged HK$467 billion per day, which amounted to a third of Hong Kong's annual Gross Domestic Product (GDP); the total value of transactions that year was 84 times the GDP of Hong Kong.
