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 three currency denominations may be settled using CHATS: Hong Kong dollar, euro, and US dollar.[1] In 2005, the dollar amount 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 volume of transactions that year was 84 times the GDP of Hong Kong.[2]

History

Prior to the launch of CHATS as a RTGS system, interbank settlements in Hong Kong relied on a multi-tier system which settled in a daily net basis. About 170 banks settled with 10 banks. These 10 banks, in turn, settled with Hongkong Bank, which then settled with the HKMA in a one-to-one basis. Hongkong Bank acted as the clearing house under this system, settling payments across its books in a net basis on the day following the transactions. The HKMA decided that this did not meet international standards as set by G10's Committee on Payment and Settlement Systems; following a six-month feasibility study, in June 1994, it decided to develop CHATS as a RTGS system.[3]

After two years of development, CHATS for Hong Kong dollars was launched on 9 December 1996.[4] CHATS for US dollars and euros were launched on 21 August 2000 and 28 April 2003, respectively.[5][6] In July 2007, the Regional CHATS Payment Services was also launched to link all participants in the three different CHATS versions for transactions involving currency exchange.[7]

Features

CHATS, like other RTGS systems, settles payment transactions on a "real time" and "gross" basis—payments are not subjected to any waiting period and each transaction is settled in a one-to-one manner such that it is not bunched with other transactions. It is a single-tier system where participants settle with one central clearing house. Payments are final, irrevocable, and settled immediately if there is sufficient funds in the participant's settlement account with the clearing house. Daylight overdraft is not offered in CHATS; payments that cannot be settled due to insufficient funds are queued. Banks are able to alter, cancel, and re-sequence payments in their queues.[3][4]

Since no daylight overdraft is offered, in order for the banks to avoid having to maintain large balances in their settlement accounts, which accrue no interest, so that payments are processed as soon as possible, interest-free intraday liquidity may be obtained by the banks through repurchase agreements, or repos. Intraday repos that are not reversed at the end of the business day are carried into overnight borrowing.[3][4]

Banks access CHATS by connecting to it via Member Bank Terminals which are provided by Hong Kong Interbank Clearing Limited. They may also develop their own software to access CHATS' terminal system provided that their software follow CHATS' messaging format and protocol.[4]

Hong Kong dollar CHATS

The HKMA, which is Hong Kong's central banking institution, acts as the clearing house for Hong Kong dollar (HKD) CHATS. All licensed banks in Hong Kong maintain HKD settlement accounts with the HKMA, and as of June 2000, restricted license banks "with a clear business need" may also open settlement accounts with the HKMA.[4] The volume of transactions in HKD CHATS in 2007, in raw number of transactions, totaled at 5,499,494.[8]
