Published by Jamie JemmesonForeign exchange traders with long-positions on the pound have been advised that the currency may fall to a three-month low against the dollar.According to Gaitame.com Research Institute, a division of Japan's biggest currency margin trader, the pound is moving towards a 'dead cross', where recent declines are pushing the currency towards its longer-term moving average, suggesting a period of extended declines.Speaking to Bloomberg, Kumiko Gervaise, an analyst at the research institute, forecast: "It now looks to be only a matter of time before the 20- day moving average falls below the 200-day moving average."If such falls are witnessed, the pound may fall as low as $1.57, a level not seen since October 13th.Elsewhere, the Financial Times has warned that 2010 will be a tough year for sterling, with some analysts predicting that it may hit parity against the euro after many close shaves.In addition to the continuing impact of the financial crisis, political uncertainty ahead of the next election is also likely to weigh on the strength of the pound.For more information on foreign exchange treasury services and risk management, visit our Corporate FX site
