SWIFT also markets software and services to financial institutions, much of it for use on the SWIFTNet Network, and ISO 9362 bank identifier codes (BICs) are popularly known as SWIFT codes.The majority of international interbank messages use the SWIFT network. As of September 2010, SWIFT linked more than 9,000 financial institutions in 209 countries and territories, who were exchanging an average of over 15 million messages per day. SWIFT transports financial messages in a highly secure way, but does not hold accounts for its members and does not perform any form of clearing or settlement. SWIFT does not facilitate funds transfer, rather, it sends payment orders, which mustiness 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. 66 8. 2. 1 BRAC Bank Swift Network Diagram Fig-8. 37 Swift Network Diagram 8. 2. 2 SWIFT Infrastructure Overview A typical SWIFT customer environment consists of a combining of individual roles that interact with each other to provide messaging services.
