The Society for Worldwide Interbank Financial Telecommunication (SWIFT) operates a worldwide financial messaging network, which exchanges messages between banks and other financial institutions. SWIFT also markets software and services to financial institutions, much of it for use on the SWIFTNet Network. ISO 9362 bank identifier codes (BICs) are popularly known as ’SWIFT codes‘.
SWIFT does not facilitate funds transfer, rather, it sends payment orders, which must be settled via correspondent accounts that the institutions have with each other. Each financial institution, to exchange banking transactions, must have a banking relationship by either being a bank or affiliating itself with one (or more) so as to enjoy those particular business features.
