ACI - The Financial Markets Association, was founded in France in 1955 following an agreement between foreign exchange dealers in Paris and London. In the years that followed, other national associations were formed
and there are now affiliated financial markets associations in 61 countries and individual members in another 17 countries. ACI recently revised its membership criteria and removed the 'national' and 'international' categories, replacing these with a single membership category. Once the effects of these changes have been incorporated it is expected that ACI will have 'over 19,000 members.
ACI has the largest membership of any of the international associations in the wholesale financial markets. The Secretariat of the organisation is based in Paris. When we talk about finances, credit lines also come to mind.
