SWIFT

The Society for Worldwide Interbank Financial Telecommunication (SWIFT) provides a network that enables financial institutions worldwide to send and receive information about financial transactions in a secure, standardized and reliable environment. SWIFT also sells software and services to financial institutions, much of it for use on the SWIFTNet Network, and ISO 9362. Business Identifier Codes (BICs, previously Bank Identifier Codes) are popularly known as "SWIFT codes".

The majority of international interbank messages use the SWIFT network. As of 2015, SWIFT linked more than 11,000 financial institutions in more than 200 countries and territories, who were exchanging an average of over 15 million messages per day (compared to an average of 2.4 million daily messages in 1995).[1] 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.¹

SWIFT does not facilitate funds transfer: rather, it sends payment orders, which must be settled by correspondent accounts that the institutions have with each other.
