Real-time gross settlement
Real time gross settlement systems (RTGS) are specialist funds transfer systems where transfer of money or securities takes place from one bank to another on a "real time" and on "gross" basis. Settlement in "real time" means payment transaction is not subjected to any waiting period. The transactions are settled as soon as they are processed. "Gross settlement" means the transaction is settled on one to one basis without bunching or netting with any other transaction. Once processed, payments are final and irrevocable.
RTGS systems are typically used for high-value transactions that require immediate clearing, in some countries the RTGS systems may be the only way to get same day cleared funds and so may be used when payments need to be settled urgently such as when purchasing a house. However most regular payments would not use a RTGS system, but instead would use a national payment system or network that allows participants to batch and net payments.
RTGS systems are usually operated by a country's Central bank as it is seen as a critical infrastructure for a country's economy. Economists view 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
Central banks and RTGS
This "electronic" payment system is normally maintained or controlled by the central bank of a country. There is no physical exchange of money; the central bank makes adjustments in the electronic accounts of Bank A and Bank B, reducing the amount in Bank A's account by $100,000 and increasing the amount of Bank B's account by the same. 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 of time. Such 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 UKs, BACS system. In the net settlement system, all the inter-institution transactions during the day are accumulated. At the end of the day, the accounts of the institutions are adjusted. The implementation of RTGS systems by central banks throughout the world is driven by the goal 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. Settlement is immediate, final and irrevocable. Credit risks due to settlement lags are eliminated. The best RTGS national payment system cover up to 95% of high-value transactions within the national monetary market.
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. Several reasons exist for central banks for RTGS adoption decisions to include counterparts in the system. 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 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 (Logica CMG of UK, CMA Small System of Sweden, JV Perago of South Africa and SIA SpA of Italy, Montran of USA) has presumably lowered the cost and hence made it feasible for many countries to adopt. By 1985, three central banks had implemented RTGS systems. At the end of 2005, the use of RTGS systems had spread to 90 central banks.
Systems in Europe covering multiple countries
TARGET2 is the Real Time Gross Settlement system for the Euro currency, and is offered by the Eurosystem, which comprises the European Central Bank and the National Central Banks of those countries that have adopted the Euro currency. The Eurosystem and the European System of Central Banks will co-exist as long as there are EU Member States outside the Euro area. TARGET2 is used for the settlement of central bank operations, large-value Euro interbank transfers as well as other euro payments. TARGET 2 provides real-time financial transfers, debt settlement at central banks which is immediate and irreversible.
