As an October 23 summit of European leaders is unlikely to yield concrete results, there will be a second one within three days.
"Sunday's summit is unlikely to produce any real decisions, the real stuff will have to be done on Wednesday or even Friday," one senior euro zone source told Reuters. "It will be another euro zone leaders' summit."
The euro was last 0.2 per cent weaker on the day at US$1.3728.
Today, Germany slashed its forecast for 2012 growth to 1 per cent, from 1.8 per cent, and eased its outlook for this year to 2.9 per cent from 3 per cent.
"The pace of expansion has slowed down, as we expected," Germany's Economy Minister Philipp Roesler said, according to Reuters. He added that "our economy remains on a growth path."
In the US, data released today were cause for cautious optimism.
Factory activity in the US Mid-Atlantic region recovered in October and the number of Americans claiming new jobless benefits declined last week.
Even so, a drop in sales of previously owned homes and a benign increase in a gauge of future growth were clear reminders that the outlook remained uncertain.
"The numbers we have seen today provide some hints that the domestic economy is doing a little bit better, even with the challenges that are unfolding in Europe," Michael Strauss, chief economist at Commonfund in Wilton, Connecticut, told Reuters.
