The USDJPY flash crash
I’ve ranted previously about people calling things “flash crashes” that don’t deserve the name. Fat fingers; gunning stops; these things aren’t a patch on the original flash crash. But what happened in USDJPY two days ago, in the witching hour between the Wednesday session in New York and the Thursday session in Singapore - that was worthy of being called a flash crash.
The least liquid time of day in the FX markets is after 5pm in New York: the NYC traders are in the pub; the Sydney traders are still waiting for their first cup of coffee to kick in; and the Tokyo and Singapore traders (except for a few dedicated souls) aren’t at their desks yet.
