One of the central dramas of the early seasons of The Wire is the cat-and-mouse game between Avon Barksdale’s drug operation and the detectives of the Major Crimes Unit. The drug dealers started off using pagers and pay phones. When the police tapped the pagers and the phones, Barksdale’s people switched to “burner” cell phones that they threw away before the police could tap them. By Season 4, Proposition Joe advised Marlo Stanfield not to use phones at all.
Well, apparently, Wall Street currency traders don’t watch The Wire. I don’t think anyone was surprised to learn that major banks including JPMorgan, Citigroup, Barclays, RBS, and UBS conspired to manipulate currency prices — something that regulators have been investigating for over a year and a half. One common strategy was cooperating to time large transactions in order to manipulate daily benchmark rates at which other client transactions are executed.
