The response of the private sector led to the establishment of the CLS and the launch of the CLS system with 39 members and seven currencies: the  BIS central bankers’ speeches  1  Australian dollar, Canadian dollar, euro, Japanese yen, Swiss franc, UK pound sterling, and US dollar in September 2002.
Since then, the system has evolved to the current state where foreign-exchange transactions in 17 currencies are settled with a peak volume to date of over 2 million transactions per day and a peak value of more than $ trillion per day. In its evolution, the CLS added four more currencies in September 2003: the Danish krone, Norwegian krone, Singapore dollar, and Swedish krona.
