I wish I knew more about the markets (currently). I wonder if the EU has cashed in is stock and shares in the UK (along with the U.S.) and now want to shut the EU door as fast as it can?
The UK is in shock now, and leaving the EU as this point is not in the UKs interests. in fact, its the strongest tool the UK has for recover and preparations. Holding the EU to ransom, for a filing day, waiting for all markets to level out and reducing the effect on the UK. (anyone in the position of the UK would probably do the same)
Sure, this is an assy thing to do to the EU, but they haven't played fair either... and looks like they wanted to just cut and run.
if the UK can keep the door open for a good 5 years (remember, the action of filing to leave is solely with the government, they can pick when, or not to at all- that would lead to civil unrest in the uk), set up pre trade negotiations with outside EU people, while the EU stays uncertain and keeps markets at a level the UK can deal with... Well, UK can come out of this doing quite well in 5-10 years
just a guess
