The euro hit a three-week high versus the dollar on Tuesday on a report that Germany could make concessions on efforts to put together a bailout for Greece, while Japanese shares rose on data suggesting industrial activity has begun to recover from a March earthquake.
The euro rose to $1.4407, its highest in three weeks, supported by a Wall Street Journal report that Germany was considering dropping its demand for an early rescheduling of Greek bonds in order to facilitate a new package of aid loans for heavily-indebted Greece.
European shares were expected to open higher, with financial spreadbetters calling Britain's FTSE 100 <.FTSE>, Germany's DAX <.GDAXI> and France's CAC-40 <.FCHI> to open up 0.7-0.8 percent.
The European Union wants to draft a second bailout package for Greece to release vital loans next month and avert the risk of the euro zone country defaulting.
Trader said the euro's next upside target was $1.45.
The euro zone problems appear to be subsiding for now. Or putting it another way, the market appears to have stopped looking at them as a factor for now, said Teppei Ino, a currency analyst at Bank of Tokyo-Mitsubishi UFJ, adding the market could focus on upcoming U.S. data releases. Key numbers including ISM manufacturing and payroll data are due this week.

Companies expect the recovery to continue in June, a sign they are making progress in recovering from the March earthquake.
Investors got past the weak data in April and cheered the strong outlook by buying futures, said Tsuyoshi Segawa, an equity strategist at Mizuho Securities.
