The Society for Worldwide Interbank Financial Telecommunication (Swift), legally S.W.I.F.T. SC, is a Belgian cooperative society providing services related to the execution of financial transactions and payments between certain banks worldwide. Its principal function is to serve as the main messaging network through which international payments are initiated. It also sells software and services to financial institutions, mostly for use on its proprietary "SWIFTNet", and assigns ISO 9362 Business Identifier Codes (BICs), popularly known as "Swift codes". The Swift messaging network is a component of the global payments system. Swift acts as a carrier of the "messages containing the payment instructions between financial institutions involved in a transaction". However, the organisation does not manage accounts on behalf of individuals or financial institutions, and it does not hold funds from third parties. It also does not perform clearing or settlement functions. After a payment has been initiated, it must be settled through a payment system, such as TARGET2 in Europe. In the context of cross-border transactions, this step often takes place through correspondent banking accounts that financial institutions have with each other. As of 2018, around half of all high-value cross-border payments worldwide used the Swift network, and in 2015, Swift linked more than 11,000 financial institutions in over 200 countries and territories, who were exchanging an average of over 32 million messages per day (compared to an average of 2.4 million daily messages in 1995). Though widely utilised, Swift has been criticised for its inefficiency. In 2018, the London-based Financial Times noted that transfers frequently "pass through multiple banks before reaching their final destination, making them time-consuming, costly and lacking transparency on how much money will arrive at the other end". Swift has since introduced an improved service called "Global Payments Innovation" (GPI), claiming it was adopted by 165 banks and was completing half its payments within 30 minutes.
