You posted this in another forum. My response is there.

The other responses here are suggesting that you will find a better relative rate in a few years. I am not predicting one way or another (I have lived in the UK for 10 years and also hold a US passport).

The USD/BPS rate is less favorable to the USD now then at any time in the last 10 years. If you take a longer view you will find that 1.80 dollars to the pound is actually much closer to the historical average then the last 10 years implies. If history is an reasonable indication of the future then I am not sure you will find the rate in 4 year favoring dollars. You might find the rate right now is about as good as it will get.

The deficit is driving a lot of the adjustment and the deficit has a long way to go.
