Well, that made for an interesting morning.

[randomness]

Polemic Paine describes the hilarity that ensued:

It’s the small hours of London Friday morning for me and the reasons for GBP's freediving world record attempt haven’t yet been formulated. Now I'm afraid that if you started reading this expecting me to tell you what is going on in GBP, then sorry, I don't know. But having worked in FX for a good chunk of my life I can have a good guess at what is now going on in the banks.

First, every salesperson is struggling to call all their clients who had 'call levels’ at zones never expected to be hit, whilst trying to fill orders in systems at levels that they think they can get away with. Oh, hang on, no they can’t do that anymore as they need audit trails. So, they will all be huddled around spot desks arguing over whose order was hit at what. Said spot dealers will be shouting a lot and staring at an automated blotter that is slowly dripping in a queue of trades that their antiquated order and back office system in some far off distant place on the planet is trying to process. Basically, there will be a lot of ‘WHAT THE FUCK IS MY POSITION.. ARRRGH ‘ going on.

Meanwhile, clients will be calling in demanding to know why their stops were done 7% below current market and why no one called them. Because if they had been called they would have bought it back at 8% below current markets because they are all retrospective geniuses.

Managers will be trying to recite the rules of engagement for filling stops but can’t find them so call compliance. However, compliance is asleep because they are mostly based in Head Office and that isn’t in the Antipodes, apart from the Antipodean banks whose compliance officers will be teaching some course to the catering staff on how not to deal with Yemeni banks.

By now the dealing systems will be catching up with what's going on and the spot traders now fit into two categories:-

Group 1 who look at their position screens and see a vast profit who split into groups 'A' and ‘B'. 'A' stays very quiet knowing that sales will want some of the profit if they see how much it is and ‘B' who stand up and declare themselves as trading Gods.

Meanwhile Group 2, on seeing vast losses, immediately write emails to every manager under the sun blaming their staggering losses on system latency and the ridiculous guaranteed stop levels that sales made them undertake. If they are lucky management will swerve the losses into a contingency book, but if they are unlucky and the bank was thinking of replacing them with a 'Raspberry Pi’ algorithm, they will be out of the door by close of Friday.

But back to sales. Those that are still on the phone are quoting the reason for the fall on anything that they feel everyone else is saying because no one has a real clue. They will probably repeat what JPMChase or Goldman say as they reckon that the guys there are cleverer than them and more likely to know. So, clients will currently be being told that it is due to- "Barriers being hit at 1.25, 1.20 , and 1.15" and if they can't even manage that will say "Stop losses”, which is a great generalised term that demands no justification. But some foolish folk will have done a Bloomberg News search for GBP and decided that it is due to the news that fracking had been allowed in North West England. Which is of course rubbish, because we all know that it happened because Diane Abbott was made the shadow Home Secretary.

By now very senior management will have come down to the dealing room. Bearing in mind this is out of London time zone, the senior managers involved will have absolutely no idea whatsoever about Sterling so will ask questions to frantic spot and sales folks along the lines of "Has Brexit been announced?" or "is this is a big move?" The frustrated dealing staff will have to tread a thin line with them, alternating between wanting to tell them to piss off and ingratiating themselves with them as, with the size of the losses they can see, they may well be up before them the following morning.
