The euro advanced across the board on Friday, jumping more than 2 percent against the yen, on optimism Greece was making progress in efforts to secure funding and stay in the euro zone.
The yen and the Swiss franc, which tend to do well during turmoil in financial markets, both lost ground as demand for riskier assets also picked up after Chinese shares rebounded.
Eurogroup President Jeroen Dijsselbloem said on Friday euro zone finance ministers may make a "major decision" when they hold an emergency session on Saturday to weigh the Greek proposal. Many in the market were optimistic, although there was a degree of caution about holding large bets going into the weekend.
A deal on Greek's debt over the weekend would ease some of the uncertainty surrounding the euro, said Joe Manimbo, senior market analyst at Western Union Business Solutions in Washington.
