ABIZZ....
No, the quotes are all from the same article which I linked to.
The FX Rate for the € factors in strong economies such as Germany and Netherlands, but also basket case economies such as Greece and the potential banking meltdown in Italy.
At the moment, lots of people believe that Germany is getting a cheap ride on the backs of what used to be called the PIGS and the markets are more concerned / worried about what could go wrong in Greece and Italy than they are correctly reflecting the performance of the German economy.
Yes the € exrate factors in all the economies in the Eurozone, ie the confidence in the Eurozone as a whole.
The £ exrate factors only the confidence in the UK economy.
When the Euro was introduced the exrate was €1.60/£1 and stayed above €1.40 until the crash in 2008 - the Pound nosedived against the Euro and the USD.
As the Uk economy improved the confidence in Sterling improved over the following years and the £ exrate improved to reach €1.43/£1 in November 2015.
Since the worry about a possible Brexit before the vote and another nosedive after the vote , we are where we are today.
The £/USD has nosedived even more.
People talk about currencies being overvalued or undervalued, what therefore is the correct value, it doesn't exist.
If the GBP stayed where it is now, it can be sustainable and under normal circumstances if the UK economy improved, it may have gained again over time.
We are hearing that the UK economy is in fantastic shape and that it will be even better when it leaves the EU from Brexiters, fine if the markets agree with this opinion. If they don't, which is why the Pound has fallen so much over the past year then the fall may be far from over.
If the Pound did nosedive again, would this be sustainable around parity with the USD or €?
Yes it has dipped to near those levels in the past but only for very brief periods of time. If it was the norm it couldn't be sustainable.
The Uk being self-sufficient and having a zero defecit is highly unlikely and the more likely scenario is the defecit will increase if the economy stalled because of Brexit.
No-one can be proved right or wrong until the Uk leave the EU.
