Sterling rose against the dollar yesterday (July 9th) and has continued to climb this morning after the Bank of England (BoE) announced that it would leave rates on hold at 0.5 per cent and keep its asset purchase programme on its current course.The pound had weakened earlier on the week amid widespread speculation that the Bank would boost the £125 billion programme by an additional £25 billion, picking up the slack offered by the Treasury.In its statement yesterday, the bank said it will "review the scale of the program again at its August meeting, alongside its latest inflation projections".Forex News reports that traders are now looking ahead to the publication of the June Producer Price Index which is due later today. Office for National Statistics figures for the May index showed that output for home sales of manufactured products fell 0.3 per cent in the year to May, compare to a rise of 1.3 per cent in the year to April.
