<p>Very recently, the GBP has been raising against the Euro. I understand this has to do with the EU injecting €1.1 trillion until Sep 2016 and the elections in Greece.</p>

<p>My question is: when is this going to stop? I am uncertain as I don't know if the result of the EUR being much lower than GBP is also the result of speculation and, for that reason, it might not go beyond that.</p>

<p>What to expect then?</p>

There is no definitive answer for this question. Small things could change this pairing drastically. What if everyone dumping the Euro decided to buy into the GBP and caused a demand spike such that the GDB increased even while the Euro dropped? We would see a bigger gap between the currencies here than if, for instance, people leaving the Euro bought more heavily into the dollar of kroner etc. I would be skeptical of any person who claimed confidence in any pairing rate.

Thanks for your comment. If everyone started dumping the Euro, there would be a cause for it. What I mean by my question: What are the factors and why should we look at them? Not looking for a black and white answer, but I'm pretty sure guidance in this subject is possible.

I think the people that are willing to pay for expert answers to this question have done so, and you can see the average of their answers in the current exchange rate. I don't think you can expect to easily find any better answer.

The expert advice I got was biased as there was a motive for selling currency or perhaps loose the sale. I'm not sure I understand your point. I came to this site to get guidance on how to evaluate the situation. The user answering the question may not have a black/white answer, but there may points worth mentioning that I can consider when evaluating. What's so unreasonable about this?

Where is GBP/EUR exchange rate going?

Very recently, the GBP has been raising against the Euro. I understand this has to do with the EU injecting €1.1 trillion until Sep 2016 and the elections in Greece.

My question is: when is this going to stop? I am uncertain as I don't know if the result of the EUR being much lower than GBP is also the result of speculation and, for that reason, it might not go beyond that.

Just today, I was reading about a specialist saying now was the best time, but that specialist was also a seller pushing for a long-term contract to buy EUR (currency.co.uk) so I am uncertain about his opinion. He mentioned 1.32 was great, but later 1.3465 was achieved!
