Overview

Real-time gross settlement (RTGS) systems are specialist funds transfer systems where the transfer of money or securities takes place from one bank to any other bank on a "real-time" and on a "gross" basis to avoid settlement risk. Settlement in "real time" means a payment transaction is not subjected to any waiting period, with transactions being settled as soon as they are processed.

However, real time does not necessarily mean immediately or instantly and can be subject to processing (e.g., wire transfers via FedWire are real time but can take hours in some cases while the issuing or reviewing bank’s wire room reviews or processes it, if necessary). "Gross settlement" means the transaction is settled on a one-to-one basis, without bundling or netting with any other transaction. "Settlement" means that once processed, payments are final and irrevocable.

History

As of 1985, three central banks implemented RTGS systems, while by the end of 2005, RTGS systems had been implemented by 90 central banks.

The first system that had the attributes of an RTGS system was the US Fedwire system which was launched in 1970. This was based on a previous method of transferring funds electronically between US federal reserve banks via telegraph. The United Kingdom and France both independently developed RTGS type systems in 1984. The UK system was developed by the Bankers' Clearing House in February 1984 and was called CHAPS. The French system was called SAGITTAIRE. A number of other developed countries launched systems over the next few years.

These systems were diverse in operation and technology, being country-specific as they were usually based upon previous processes and procedures used in each country.

Operation

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.

Existing systems

In 2010, the World Bank published a report on payment systems worldwide, which investigated these countries' usage of real-time gross settlement systems for large-value payments.
