The pound is at a historical prolonged low - except compared to the miners strike during 1984-5.
But it's interesting how the markets did not predict that remain could lose:
* On the 28th of May 2015, the EU referendum act was introduced. One pound in dollars was 1.46.
* It came into force on the 1st of Feb 2016, one pound in dollars was 1.42.
* On the 22nd of June 2016, the day before the referendum, one pound in dollars was 1.46 USD.
* By the 30th of June 2016, one pound in dollars was at 1.33, and it's stayed around the 1.30 mark for a long time.
* Right now it's only dropped to 1.28.
So I ask you:
If the markets foresaw the referendum (which the polls showed was always pretty close 51-49), why did the price of pounds not drop further before the referendum? Surely they knew there was a risk of 'leave' winning? Some people claim it was already 'priced in', however we can't see a significant drop between the legislation being announced, and the polls showing the election is close.
The conclusion I draw is that the markets aren't rational. Until the 'apocalyptic event' happens, people don't believe it will happen.
So that's why the pound didn't drop _before_ the referendum. Similarly, the pound will not drop before the UK drops out with no deal (despite it being a real possibility), because these things don't get priced-in in advance.
However, if there is no deal, we should probably see very large market movements.
