In a word, nothing
Recent stronger data releases have reduced the call/need for additional easing and I ( and everyone else ) expect the BOE to keep rates and QE on hold when they announce at 11.00 GMT
More likely to give rise to risk is the industrial and manufacturing production data due out at 08.30 GMT. Traders are positioning for positive readings given the recent better than expected PMI releases so the risk will be to the downside.
GBPUSD currently going nowhere fast at 1.5550, but attracting a few buyers in the dip.
EURGBP just popping back up to 0.8461 from session lows of 0.8456 as EURUSD makes a stronger rally to 1.3158
