RTGS systems are usually operated by a country's
central bank as it is seen as critical infrastructure for a country's economy. Economists believe that an efficient national payment system reduces the cost of exchanging
goods and services, and is indispensable to the functioning of the interbank, money, and capital markets. A weak payment system may severely drag on the stability and developmental capacity of a national economy; its failures can result in inefficient use of financial resources, inequitable risk-sharing among agents, actual losses for participants, and loss of confidence in the financial system and in the very use of money. RTGS system does not require any physical exchange of money; the central bank makes adjustments in the electronic accounts of Bank A and Bank B, reducing the balance in Bank A’s account by the amount in question and increasing the balance of Bank B’s account by the same amount. The RTGS system is suited for low-volume, high-value transactions. It lowers settlement risk, besides giving an accurate picture of an institution’s account at any point in time. The objective of RTGS systems by central banks throughout the world is to minimize risk in high-value electronic payment settlement systems. In an RTGS system, transactions are settled across accounts held at a central bank on a continuous gross basis. The settlement is immediate, final, and irrevocable. Credit risks due to settlement lags are eliminated. The best RTGS national payment systems cover up to 95% of high-value transactions within the national monetary market. RTGS systems are an alternative to systems of settling transactions at the end of the day, also known as the net settlement system, such as the
BACS system in the United Kingdom. In a net settlement system, all the inter-institution transactions during the day are accumulated, and at the end of the day, the central bank adjusts the accounts of the institutions by the net amounts of these transactions. The
World Bank has been paying increasing attention to payment system development as a key component of the financial infrastructure of a country and has provided various forms of assistance to over 100 countries. Most of the RTGS systems in place are secure and have been designed around international standards and best practices. There are several reasons for central banks to adopt RTGS. First, a decision to adopt is influenced by competitive pressure from the global financial markets. Second, it is more beneficial to adopt an RTGS system for the central bank when this allows access to a broad system of other countries' RTGS systems. Third, it is very likely that the knowledge acquired through experiences with RTGS systems spills over to other central banks and helps them make their adoption decision. Fourth, central banks do not necessarily have to install and develop RTGS themselves. The possibility of sharing development with providers that have built RTGS systems in more than one country (
CGI of UK holding the IP, CMA Small System of Sweden, JV Perago of South Africa,
SIA S.p.A. of Italy and Montran of USA) has presumably lowered the cost and hence made it feasible for many countries to adopt. == Existing systems ==
