In a modern economy transactions between parties usually involve the exchange of items such as capital goods, labor, manufactured goods, services and legal claims for a “cash” consideration. The exchange may involve more than one currency and may involve a time difference between delivery of goods and actual payment. Such exchange transactions carry with them a number of risks including settlement failure and fraud. Financial organizations cooperate with one another to establish the infrastructure and procedures necessary to minimize these risks and transaction costs. These include formal markets such as stock exchanges, and automated systems to enable payments to be made both within individual countries and also cross-border.
The provision of clearing and payment systems is one of the most important operational services that banks provide. Payment systems may be either national or cross-border.
The most important international system is provided by the Society for Worldwide Interbank Financial Telecommunications (SWIFT). This is a cooperative owned by 7000 members operating in approximately 200 countries. SWIFT was established in 1973 and is based in Brussels, Belgium, but has operational centers around the world.
SWIFT provides two key services. First it provides a global telecommunications network to enable banks and other financial institutions to exchange electronic messages to instruct transfers of funds in a secure manner. Second it coordinates the standardization of the format of these messages. The latter is vital to allow banks to send, receive and interpret electronic payment instructions in an automated way.
SWIFT has three principal challenges. It must ensure it provides a secure service, maintains an extremely high level of reliability and has a well-managed implementation of changes in message formats or communications protocols. Most countries have their own clearing systems for payments made between banks, and on behalf of customers with accounts at these banks. The vast majority of these systems concern electronic transfers of funds but other means have to be used for payments involving paper checks.
