The European Commission found that in the period from 18 December 2007 to 31 January 2013 “some individual traders in charge of Forex spot trading of these currencies on behalf of the relevant banks exchanged sensitive information and trading plans, and occasionally coordinated their trading strategies through various online professional chatrooms”.
The commercially sensitive information exchanged by the banks in these chatrooms related to: outstanding customers’ orders (i.e. the amount that a client wanted to exchange and the specific currencies involved, as well as indications on which client was involved in a transaction); bid-ask spreads (i.e. prices) applicable to specific transactions; their open risk positions (the currency they needed to sell or buy in order to convert their portfolios into their bank’s currency); and other details of current or planned trading activities.
The information exchanges, following the tacit understanding reached by the participating traders, enabled them to make informed market decisions on whether to sell or buy the currencies they had in their portfolios and when.
Occasionally, these information exchanges also allowed the traders to identify opportunities for coordination, for example through a practice called “standing down” (whereby some traders would temporarily refrain from trading activity to avoid interfering with another trader within the chatroom).
The banks settled with the European Commission, thereby acknowledging their participation in the cartels.
