There are multiple factors behind Sterling’s collapse in the past fortnight to decade lows and the question remains whether these factors will reverse any time soon.
At the top of the pyramid of causes for Sterling’s demise, in my view, is not the UK’s large current account deficit or Bank of England (BoE) policy but the stance on EU membership which Prime Minister Theresa May has adopted.

Moreover, Theresa May will be subject to the will of her own Conservative Party – which on the whole supports membership of the UK or at least a softer form of exit from the EU – and of the people.
