As was pointed out many times prior to, and after, the vote, the pound was already on a downward trend to adjust for previous overpricing. The pound had already fallen from a high in 2015 of around 1.43 (up gradually from 2012/13 when it was around 1.16)

To attribute this solely to Brexit is a false premise. It was however a good excuse to finish the expected realignment swiftly.

You comment on my not responding.
By concentration on the exchange rate you are not responding to the expected a) massive black hole in the economy b) massive unemployment which were also forecast as being immediate responses to a leave vote. Do you agree that these did not occur? In which case 'project fear' was false.
