What is the Essex Express and how does it impact forex trading? It is a commuter train which is shared by several key traders from different banks such as the Swiss bank UBS, the Japanese bank MUFG Bank and UK banks Barclays and RBS. Inside the train, they created a forex trading cartel in order to influence market prices. Another forex trading cartel created by traders on the Essex Express was the “Three-Way-Banana-Split” operated by traders from Swiss bank UBS, UK banks Barclays and RBS and US banks Citigroup and JPMorgan who collaborated in a chat room by that name.
