Keep a very close eye on the UK political news over the next couple of weeks if you are looking to trade this pair.
In the event of a tory leadership election to oust Theresa May, I have reason to believe that this would be short term bearish for the GBP due to the increased uncertainty. This happened last year during the post-Brexit Conservative party leadership election.
Conversely, the Conservative Party have now agreed to form a coalition government with the DUP of Northern Ireland; this could possibly result in a 'soft Brexit' on the cards as opposed to a 'hard Brexit', reason being Theresa May no longer has a mandate or the support for a 'hard Brexit'. The DUP will also likely make demands for the NI/Ireland border to remain a 'soft border' like it currently is - this would require the UK to retain freedom of movement within the EU, which could also mean that the UK remains in the single market. This would be bullish for the GBP in the long term as a result of the reduced economic risk, especially in the services sector which makes up close to 80% of the UK economy.
I am expecting continued heavy volatility in this pair over the next few weeks.
Short term buys are in the 1.262-1.264 previous region.
