Well this is the rumour service, so here goes. There's noise of another rogue trader, this time at Merrill Lynch. It's being rumoured that the individual is/was a Forex trader who was taking a long position on the Dollar. It's being said that ML will be taking a significant hit, in the region of $500m. Though, next to its billion dollar write-downs this figure appears insignificant. Could be interesting, though, since it could open a can of worms.
