Posted by Zeb BhamOngoing uncertainty about the financial situation in the eurozone is a factor that may be impacting foreign exchange trading at present.According to Reuters, the single currency yesterday (August 17th) slipped from its best performance in three weeks versus the US dollar - seen on Tuesday - to $1.4404, a 0.2 per cent tumble.Commenting on the situation, FX strategist at BNP Paribas in Singapore Rob Ryan suggested that fears about the debt issues spreading to other European nations have been quelled slightly by the European Central Bank's (ECB's) bond purchases."If the ECB feels the politicians are not moving, that they are beginning to rely on the ECB, they will have no choice but to step back again," he said.The comments are similar to those made to the newswire earlier this week by a trader at Kepler Capital Markets in Paris Patrice Perois, suggesting investors were left unconvinced about the strength of the eurozone following a meeting between German chancellor Angela Merkel and French president Nicholas Sarkozy.For more information on foreign exchange treasury services and risk management, visit our Corporate FX site
