Swift is a Belgian cooperative founded in 1973 and owned by its member banks, and it operates the messaging network through which most cross-border payment instructions travel between financial institutions worldwide. It is important to understand what it is not: Swift moves messages rather than money, and the actual funds settle through correspondent bank accounts, which is why the network became such an effective instrument for sanctions enforcement. Headquartered in La Hulpe near Brussels, it connects more than eleven thousand institutions in over two hundred countries and is under sustained pressure from instant payment schemes and blockchain settlement alternatives.
