The euro rose on Tuesday on speculation that European Union nations could bail out errant member Greece, while global stocks were flat and emerging market shares climbed.
Expectations about a rescue for Greece followed news that European Central Bank President Jean-Claude Trichet was leaving a meeting of central bankers in Sydney early to attend a European Union leaders' summit.
EU leaders will hold a special summit on the economy on Thursday in Brussels amid increasing worries that Greece and other so-called peripheral euro zone economies cannot handle their debts and deficits.

The euro was up half a percent at $1.3716 and three-quarters of a percent at 122.83 yen.
