Published by Zeb BhamUncertainty remains about the euro in foreign exchange markets and there is concern among some economists that more European countries could soon require financial assistance similar to that currently being provided to Greece.That is according to Reuters, which suggested that analysts are awaiting further indicators on the state of the market from the European Central Bank policy meeting.Meanwhile, Portugal's credit rating was downgraded by Moody's to junk status as the single currency edged higher versus the greenback today (July 6th) to $1.4460, a 0.2 per cent rise.Commenting on the move, Koji Fukaya, Credit Suisse Securities in Tokyo's director of global foreign exchange research, said: "The Portugal news doesn't really change fundamentals. That's why the market's reaction was limited to one day. If we were talking about Spain, now that would be a totally different story."The week started positively for the euro as on Monday it traded at $1.4553, which Bloomberg noted was its best performance against the dollar in several weeks.For more information on foreign exchange treasury services and risk management, visit our Corporate FX site
