As the extent and brutality of the Russian invasion of Ukraine has intensified, the United States, the European Union and the North American Treaty Organization (NATO) have responded with a remarkably consistent and unified regime of economic sanctions targeted at strangling the Russian economy. Last Saturday, the White House announced agreement on prohibiting certain Russian financial institutions for accessing the SWIFT global payment processing network. This step is so significant that the French Finance Minister dubbed it the “financial nuclear option”, and yet many people are unfamiliar with SWIFT or just how important it is to the efficient functioning of the global financial system.
Headquartered in Brussels, the Society for Worldwide Interbank Financial Telecommunication (SWIFT) is a massively interconnected communication network used to initiate, verify and transmit instructions about cross-border money and securities transfers around the globe. The organization is a non-profit consortium owned and governed by member financial institutions including many large banks, brokerage firms and central banks like the Federal Reserve and the Bank of England. The membership currently includes over 11,000 financial institutions in 213 countries and processes over half of all international financial transactions.
While SWIFT does not actually move any money, the system is relied upon to rapidly convey instructions regarding transfers between banks in different countries and validate those instructions quickly and electronically. Think of it as the Instant Messager for international finance.
Prior to 1977, financial transfers between banks in different countries required cumbersome and time-consuming manual communications over the primitive telecommunication service known as Telex (if you’re over 50, ask your dad or watch a 1960’s spy movie).
SWIFT was founded in 1973 by a collective of European and North American banks and originally included 239 institutions in 15 countries. Initial work focused on setting standards and designing a computer system for transmitting transaction instructions under a unified protocol. The system went live in 1977 and expanded rapidly. Today, SWIFT processes over 40 million instructions every day and facilitates the transfer of trillions of dollars’ worth of cash and securities.
