The euro inched up in choppy trading on Tuesday on hopes squabbling policymakers will come up with a solution to avoid a default by Greece, sentiment that also buoyed Asian shares.
Markets are waiting for a confidence vote on the government in the Greek parliament later in the day, a step toward the passage of more spending cuts in exchange for foreign loans.
Meanwhile, international lenders are making an unexpected visit to Athens to check on its resolve to implement painful austerity plans that have caused weeks of public protests and political confusion.
The euro last traded at $1.4340, well above the three-week low of $1.4073 it hit last Thursday, but down from the day's high of $1.4385.
In the big scheme of things, market players are starting to believe that euro zone policy makers, especially German policy makers, will try to avoid a hard landing in Greece, said Makoto Noji, senior strategist at SMBC Nikko Securities.

Japan's Nikkei average <.N225> was up 0.6 percent at 9412.87, MSCI's index of Asia-Pacific stocks <.MIAPJ0000PUS> excluding Japan was up 0.7 percent, and indices in Hong Kong and South Korea also rose.
The outlook for the Nikkei was largely rangebound trading for the rest of June, an analyst said.
At least until the central bank's tankan is out (on July 1), rises are likely to be limited to around 9,500, said Kenichi Hirano, a strategist at Tachibana Securities, referring to the Bank of Japan's quarterly survey of corporate sentiment.
The market has priced in bad sentiment for the April-June quarter, but if the outlook for July-September is bright, the market may rise further.
