Political factors will remain extremely important with the UK parliament returning from recess on Tuesday.

CFTC data will need to be watched very closely late in the US trading on Friday.

The Bank of England is unwilling to cut interest rates as long as a disruptive Brexit is avoided while the ECB will announce a comprehensive monetary-easing package in September.
