Sterling slides for fourth straight session ahead of BoE

Sterling fell against the dollar in American trade following earlier data from Britain, and amid a lack thereof from the US, the world's largest economy. 

As of 05:22 GMT, GBP/USD fell 0.62% to 1.3863 from the opening of 1.3949, with an intraday low at 1.3859, and a high at 1.3994. 

Earlier UK data showed the Halifax House Price Index dipped 0.6% in January, compared to a 0.8% drop in December, while analysts expected a 0.2% rise, as investors now await Bank of England's policy meeting on Thursday, expected to hold interest rates unchanged at 0.50% and the assets purchase program at 435 billion pounds. 

Earlier from the US, Federal Reserve Bank of New York President William Dudley spoke about banking culture at an event jointly hosted by Thomson Reuters and the European American Chamber of Commerce, in New York, while markets await Federal Reserve Bank of San Francisco President John Williams' speech at a community leaders luncheon, in Honolulu.
