The euro hit a 4-day high against the dollar on Wednesday, after the European Commission said it would endorse Greece's plan to cut its budget deficit below the European Union ceiling of 3% of GDP by the end of 2012.
At the start of the European trading session, EUR/USD hit 1.3989, its highest rate since last Thursday. The pair was likely to find resistance at 1.4194, last Monday's high, and support at 1.3852, Monday's low.
The euro also rose 0.13% against the yen, reaching 126.36.
Worries over Greece's fiscal heath have hurt the euro over recent weeks.
On Tuesday, EC President Jose Manuel Barroso said in a statement that, "The Commission has assessed the program. The envisaged correction of the deficit is feasible but subject to risks."
