Its 2.30am in London, so there are only a few hours before bums hit seats at the Bank of England .
There is some chatter about (its speculation) that the BoE will implement an emergency rate hike to dissuade further GBP selling. This will be a death knell for the UK economy (I'm overstating it, it won't die but it will be a catastrophic step for the economy).
Alternatively, that the Bank will step in to buy GPB, placing 'floor' bids or paying offers.
Stay tuned.
ps. Please ignore those explaining this as a 'fat finger' or a 'flash crash'. Its neither. Its fundamentally driven selling and then 'get me the **** out' selling on top of it.
