The scenario sounds familiar. A front page in the next day's UK press is released showing a Brexit-related story (in this case a second Scottish independence referendum) which is negative for the pound. Sterling starts selling off just after 10am Australian time and actually starts to sell off quite aggressively as the story spreads.
A story about October 7 and the sterling flash crash? Absolutely not. It happened this morning and would have prompted a few hearts to beat faster than usual on FX trading desks.
