FX Sweeps now offered by my broker...US$?

[catt]

My SIPP broker has just introduced this:

FX SWEEPS: Elect to convert cash held in your Standard or SIPP account into your chosen currency.

I do not trade forex but am aware of the trends in major currency pairs.

I am assuming this is an overnight sweep facility. If that is the case, would it be worth my while to sweep my daily cash balance into US dollars?

Any pointers much appreciated, thanks.

I should add that I am in the UK and my cash balance is in GBP.
