FXStreet (Edinburgh) - The selling pressure remains unabated around the sterling today, dragging GBP/USD to the proximity of 1.4420, or fresh multi-year lows. GBP/USD weaker on data, yield spread The yields spread differential between the UK Gilts and US-T, mainly in the short end of the curve, keep favouring the latter and thus giving extra legs to the dollar, exacerbating the pair’s decline. In addition, the sterling is deriving further weakness from November’s poor Industrial and Manufacturing Production figures, adding to the recent deterioration of economic prospects for the UK economy. GBP/USD important levels The pair is now losing 0.82% at 1.4423 and a breakdown of 1.4400 (psychological level) would expose 1.4346 (low Jun.8 2010) and then 1.4229 (2010 low May 20). On the flip side, the next resistance aligns at 1.4947 (high Dec.24) ahead of 1.5015 (55-day sma) and finally 1.5158 (100-day sma). For more information, read our latest forex news.
