Foreigner German for “banging the close.”
Banging the close was one of two unethical things several currency market traders said they could do to game exchange rates because a handful of large banks controlled half the market, according to a June 2013 article in FAZ.net. Traders at the big banks could input trades before and after a huge trade’s 60-second window and have an effect on the rate, despite the fact that “The benchmark exchange rates are based on actual transactions and not on banks’ estimates like the L.I.B.O.R. reference rate is.” The second thing was to arrange their day’s work around a pending large trade; they would get a poorer exchange rate for the client in order to buy back her sold currency more cheaply than would have been the case.
The June 2013 article also said authorities were investigating benchmark manipulation in crude oil and swap markets.
