The projection is for Sterling to go down 25-30% against the dollar, so I expect the pound to be well below a Euro as well, and it will happen pretty soon.
We have had near parity with the dollar not so long ago and the long term average was around 1.65, so a fall from the current levels is to be expected in the circumstances (QE, massive deficit and debt).
The Pound already fell from $2.10 to $1.48 which is about than 30%.
Illinois is bankrupt, California is bankrupt, Florida is bankrupt. There is no reason for the $ to be as strong as it is now, let alone gain another 25% versus Pound…
Pound might go under 1 Euro temporary but will not stay there unless Greece and Portugal are kicked off Euro zone.
