This morning’s flash crash in Cable in which it dropped 9.5% in seconds and the low of which is still disputed raise some interesting questions for the creators of the FX Code of Conduct.
Several sources say that the mayhem was triggered by one account executing a large trade into the market, possibly for GBP 200 million. This was enough to send the market into freefall as liquidity during the already thin early Asian session, thinned out further.
If the order was executed by one account, or even by several accounts on behalf of one customer, questions have to be asked about why they did it then, and how they executed.
There is nothing like a flash event to get people excited and for news outlets to dust off and update the old “blame the algos” stories for publication. Equally, there are members of our industry of a (ahem) certain generation who are quick to jump on the bandwagon with the rejoinder “it wasn’t like that before the machines”.
As a member of that “certain” generation I can assure readers that it is utter nonsense and that last week's flash event was triggered by a human.
